Abstract

A power tool combination includes a power tool and an auxiliary handle. The auxiliary handle includes a second grip, a clamping assembly, and a locking assembly that includes an operation member. When a position state of the operation member is changed, the locking assembly is switched between a locked state and a released state. When the locking assembly is switched to the released state, the operation member applies a drive force to at least one of a first clamping arm and a second clamping arm so that the first clamping arm and the second clamping arm move away from each other.

First claim

What is claimed is:

1 . A power tool combination, comprising:
a power tool comprising a housing comprising a substantially tubular first housing and a first grip for holding, wherein the first grip is formed on or connected to the first housing; and an auxiliary handle comprising:
a second grip;
a clamping assembly connected to the second grip and comprising a first clamping arm and a second clamping arm that are disposed opposite to each other to clamp the first housing; and
a locking assembly having a locked state where a relative movement between the clamping assembly and the first housing is restrained and a released state where the first clamping arm and the second clamping arm are caused to move away from each other to allow the relative movement between the clamping assembly and the first housing,
wherein the locking assembly comprises an operation member, when a position state of the operation member is changed, the locking assembly is switched between the locked state and the released state, and, when the locking assembly is switched to the released state, the operation member applies a drive force to at least one of the first clamping arm and the second clamping arm so that the first clamping arm and the second clamping arm move away from each other, and wherein the auxiliary handle further includes a connecting rod, the connecting rod including a smooth segment and a threaded segment, where the smooth segment is connected to the second grip, and the threaded segment is disposed at an end of the smooth segment facing away from the second grip.

2 . The power tool combination according to claim 1 , wherein the at least one of the first clamping arm and the second clamping arm is connected to the operation member.

3 . The power tool combination according to claim 1 , wherein the locking assembly further comprises a connector connecting the first clamping arm to the second clamping arm.

4 . The power tool combination according to claim 3 , wherein the connector is driven by the operation member.

5 . The power tool combination according to claim 3 , wherein positions of the operation member comprise a first position corresponding to the locked state and a second position corresponding to the released state, and the first position is different from the second position.

6 . The power tool combination according to claim 5 , wherein the operation member rotates about a second axis to switch between the first position and the second position, and the second axis intersects with an extension direction of the second grip.

7 . The power tool combination according to claim 5 , wherein the operation member rotates about a second axis to switch between the first position and the second position, the connector is rotatably connected to the operation member and is rotatable relative to the operation member about a third axis, and the third axis is offset from the second axis.

8 . The power tool combination according to claim 5 , wherein a first end of the connector is connected to the first clamping arm, and a second end of the connector is limited by the second clamping arm when the operation member is at the first position.

9 . The power tool combination according to claim 8 , wherein a limit member is disposed on the second clamping arm, and the second end of the connector is limited by the limit member.

10 . The power tool combination according to claim 1 , wherein, when the position state of the operation member is changed, the operation member drives the at least one of the first clamping arm and the second clamping arm to slide along an extension direction of the second grip.

11 . The power tool combination according to claim 1 , wherein, when the position state of the operation member is changed, a position state of the second grip relative to the housing is not changed.

12 . The power tool combination according to claim 1 , wherein, when the position state of the operation member is changed, a position of the operation member relative to the second grip is changed.

13 . The power tool combination according to claim 1 , wherein the first housing is configured to have a longitudinal axis, and the locking assembly is located above the first housing in a direction of the longitudinal axis.

14 . The power tool combination according to claim 13 , wherein an extension direction of the second grip is substantially perpendicular to the longitudinal axis.

15 . A power tool combination, comprising:
a power tool comprising a housing comprising a substantially tubular first housing and a first grip for holding, wherein the first grip is formed on or connected to the first housing; and an auxiliary handle comprising a second grip, a clamping assembly connected to the second grip and comprising a first clamping arm and a second clamping arm that are disposed opposite to each other to clamp the first housing, and a locking assembly having a locked state where a relative movement between the clamping assembly and the first housing is restrained and a released state where the first clamping arm and the second clamping arm are caused to move away from each other to allow the relative movement between the clamping assembly and the first housing, wherein the locking assembly further comprises an operation member, when a position state of the operation member is changed, the operation member drives at least one of the first clamping arm and the second clamping arm to move, and, when the position state of the operation member is changed, a position state of the second grip relative to the housing is not changed, and wherein the auxiliary handle further includes a connecting rod, the connecting rod including a smooth segment and a threaded segment, where the smooth segment is connected to the second grip, and the threaded segment is disposed at an end of the smooth segment facing away from the second grip.

16 . An auxiliary handle suitable for connection to a substantially tubular first housing of a power tool comprising:
a second grip; a clamping assembly connected to the second grip and comprising a first clamping arm and a second clamping arm that are disposed opposite to each other to clamp the first housing; and a locking assembly having a locked state where a relative movement between the clamping assembly and the first housing is restrained and a released state where the first clamping arm and the second clamping arm are caused to move away from each other to allow the relative movement between the clamping assembly and the first housing, wherein the locking assembly comprises an operation member, when a position state of the operation member is changed, the locking assembly is switched between the locked state and the released state, and, when the locking assembly is switched to the released state, the operation member applies a drive force to at least one of the first clamping arm and the second clamping arm so that the first clamping arm and the second clamping arm move away from each other, and wherein the auxiliary handle further includes a connecting rod, the connecting rod including a smooth segment and a threaded segment, where the smooth segment is connected to the second grip, and the threaded segment is disposed at an end of the smooth segment facing away from the second grip.

17 . The auxiliary handle according to claim 16 , wherein, when the position state of the operation member is changed, the operation member drives the at least one of the first clamping arm and the second clamping arm to slide along an extension direction of the second g
