Abstract

A hedge trimmer includes a first housing with a first handle, a second housing with a second handle, a transmission mechanism combined to the first housing, a trimming blade for being driven by the transmission mechanism to carry out a shearing motion, an electric motor combined to the first housing and for driving the transmission mechanism, and a battery pack combined to the second housing and for supplying power to the electric motor. The first and second housings respectively include first and second rotation connection parts for making them be connected and rotatable around a rotation axis. The second housing has first and second rotation positions when being rotated with respect to the first housing. A plane perpendicular to the rotation axis is obliquely intersected with a plane perpendicular to a longitudinal axis of the trimming blade.

First claim

What is claimed is:

1 . A hedge trimmer comprising:
a trimming blade, extending along a longitudinal axis, configured for carrying out a reciprocating motion; a first housing, being formed or connected with a first handle, having a first locking portion; a second housing, being formed or connected with a second handle, and rotatable with respect to the first handle around a rotation axis, wherein a plane perpendicular to the rotation axis is obliquely intersected with a plane perpendicular to a longitudinal axis of the trimming blade; a transmission mechanism, being combined to the first housing, for driving the trimming blade; an electric motor, being combined to the first housing, for driving the transmission mechanism; a battery pack, being combined to the second housing ,for supplying the electric motor with electric power; a trigger configured for controlling the electric motor; and a control member, being movably connected to the first housing or the second housing, comprising a stopper portion and a second locking portion cooperable with the first locking portion; wherein the control member has a first position and a second position with respect to the second housing whereby, when the control member is at the first position, the first locking portion and the second locking portion are engaged with each other and the first housing and the second housing are relatively fixed, and, when the control member is at the second position, the stopper portion stops movement of the trigger, the first locking portion and the second locking portion are disengaged with each other, and the second housing is allowed to rotate with respect to the first housing around the rotation axis.

2 . The hedge trimmer as claimed in claim 1 , wherein the first locking portion is formed with a recess and the second locking portion is formed with a protrusion matched with the recess.

3 . The hedge trimmer as claimed in claim 1 , wherein the control member further comprises a manipulating portion located between the second handle and the battery pack.

4 . The hedge trimmer as claimed in claim 1 , wherein the hedge trimmer further comprises a biasing member fixedly connected to the second housing for applying a biasing force to enable the control member to move from the second position to the first position.

5 . The hedge trimmer as claimed in claim 1 , wherein the control member is slidable between the first position and the second position along a linear path.

6 . The hedge trimmer as claimed in claim 1 , further comprising a damping member wherein the damping member is disposed between a first rotation connection part of the first housing and a second rotation connection part of the second housing.

7 . The hedge trimmer as claimed in claim 1 , wherein the first housing defines a plurality of recesses for facilitating the control member to lock a relative position of the first housing and the second housing and an angle difference of adjacent ones of the plurality of recesses is 15° or an integer times of 15° in a circumferential direction of the rotation axis.

8 . The hedge trimmer as claimed in claim 1 , wherein the second housing has a first rotation position and a second rotation position with respect to the first housing and, when the second housing is rotated to the first rotation position, a plane in which a longitudinal axis of the second handle locates is parallel to the longitudinal axis of the trimming blade and, when the second housing is rotated to the second rotation position, the second handle is rotated 90 degrees with respect to the first rotation position.

9 . The hedge trimmer as claimed in claim 8 , wherein, when the second housing is rotated to the second rotation position, the second handle and the battery pack are located at two sides of a plane defined by intersection of an axis of the electric motor with the longitudinal axis of the trimming blade.

10 . The hedge trimmer as claimed in claim 1 , wherein the rotation axis and an axis of the electric motor are obliquely intersected.

11 . A hedge trimmer comprising:
a first housing, formed or connected with a first handle, having a first rotation connection part; a second housing, formed or connected with a second handle, having a second rotation connection part being connected with the first rotation connecting part and rotatable around a rotation axis between a first rotation position and a second rotation position with respect to the first rotation connection part, wherein a plane perpendicular to the rotation axis and a plane perpendicular to a longitudinal axis of a trimming blade are obliquely intersected; a transmission mechanism, associated with the first housing; a trimming blade, configured to be driven by the transmission mechanism to carry out a shearing motion; an electric motor, associated with the first housing, configured for driving the transmission mechanism; and a battery pack, associated with the second housing, configured for supplying power to the electric motor.

12 . The hedge trimmer as claimed in claim 11 , wherein, in the plane perpendicular to the longitudinal axis of the trimming blade, the first rotation connection part and the electric motor are located at a same side of the trimming blade.

13 . The hedge trimmer as claimed in claim 11 , wherein in the plane perpendicular to the longitudinal axis of the trimming blade, the first rotation connection part and the first handle are located at a same side of the trimming blade.

14 . The hedge trimmer as claimed in claim 11 , wherein, when the second housing is rotated to the first rotation position, a plane in which a longitudinal axis of the second handle locates is parallel to the longitudinal axis of the trimming blade and, when the second housing is rotated to the second rotation position, the second handle is rotated with 90 degrees with respect to the first rotation position.

15 . The hedge trimmer as claimed in claim 14 , wherein the second handle has a midsplit plane, and the second handle is at least partly symmetrical with respect to the midsplit plane and, when the second housing is rotated to the first rotation position, the midsplit plane of the second handle is parallel to the longitudinal axis of the trimming blade.

16 . The hedge trimmer as claimed in claim 14 , wherein the second handle has a midsplit plane, the second handle comprises a main handle portion for facilitating a user to grip, the main handle portion is disposed symmetrical with respect to the midsplit plane and, when the second housing is at the second rotation position, in the midsplit plane, the main handle portion and a center of gravity of the battery pack are located at two sides of the longitudinal axis of the trimming blade.

17 . The hedge trimmer as claimed in claim 11 , wherein, when the second housing is rotated to the first rotation position, in a direction parallel to the longitudinal axis of the trimming blade, the second handle is rotated to the nearest position distant from the first handle and, when the second housing is rotated to the second rotation position, a distance between the second handle and the first handle is greater than a distance between the second handle and the first handle when the second housing is rotated to the first rotation position.

18 . The hedge trimmer as claimed in claim 17 , wherein, when the second housing is rotated to the second rotation position, the second handle and the battery pack are located at two sides of the longitudinal axis of the trimming blade.
