Abstract

A clench wrench includes a structure defining a handle and an engaging head. The engaging head has a front side and a back side and includes an engaging space extending through the front and back sides. The engaging space defines an opening on both the front and back sides. A clenching device is mounted on the engaging head and includes a clenching member. The clenching member includes a clenching portion and is operable in a first mode in which the clenching portion is located at a first position capable of clenching the object engaged with the engaging head, and in a second mode in which the clenching portion is disposed away from the engaging space and is located at a second position capable of letting the object engaged with the engaging head to disengage therefrom.

First claim

What is claimed is:

1. A clench wrench comprising:
a structure including a first body defining a handle for a user to grasp and a second body defining an engaging head for engaging with an object to be clenched, wherein the engaging head includes an engaging space for receiving the object to be clenched and to be driven by the clench wrench, wherein the engaging head has two opposite sides with one side defining a front side and the other side defining a back side respectively, with the engaging space extending through the front and back sides and defining an opening each of the front and back sides; and
a clenching device mounted on the engaging head, with the clenching device including a clenching member connected with the engaging head, wherein the clenching member includes a fixed end, a clenching portion at a free end opposite to the fixed end, and a middle portion extending between and interconnecting the fixed end and the clenching portion, wherein the middle portion and the fixed and free ends, in a lateral direction, each have a cross-sectional area, wherein the cross-sectional area of the middle portion is smaller than the cross-sectional areas of the respective fixed and free ends, wherein the fixed end is immovably fixed to the engaging head and includes an abutment surface abutting with a shoulder of the engaging head preventing pivoting of the fixed end relative to the engaging head, with the clenching member being resilient with the clenching portion being moveable relative to the fixed end when pushed to deform the middle portion from a first mode in which the clenching portion is located at a first position capable of clenching the object engaged with the engaging head and a second mode in which the clenching portion is disposed away from the engaging space and is located at a second position capable of letting the object engaged with the engaging head to disengage therefrom, with the middle portion being free of contact with the object to be clenched in the first and second members.

2. The clench wrench as claimed in claim 1 wherein the clenching member is disposed on one of the front and back sides of the engaging head.

3. The clench wrench as claimed in claim 2 , wherein the fixed end of the clenching member and one of the front and back sides of the engaging head respectively include a hole and a first engaging hole, and wherein a first fastener inserts into the hole and the first engaging hole and fastens the fixed end of the clenching member on the engaging head.

4. The clench wrench as claimed in claim 3 , wherein the clenching member is a metallic member.

5. The clench wrench as claimed 1 , wherein the clenching portion is located at the first position when the clenching portion is not pushed.

6. The clench wrench as claimed in claim 1 , wherein the clenching member is a metallic member.

7. The clench wrench as claimed in claim 1 , wherein the clenching portion of the clenching member has an outer edge forming a sloped guiding edge, wherein the object inserting into the engaging space movably abuts against the sloped guiding edge, and wherein the sloped guiding edge has a lower end and an upper end extending divergently in an insertion direction of the object into the engaging space.

8. The clench wrench as claimed in claim 1 , wherein the engaging space is defined by an inner periphery of a ratchet wheel, wherein the ratchet wheel is rotatably engaged with the engaging head and has a center of rotation about an axis, and wherein the axis extends in a thickness direction of the engaging head.

9. The clench wrench as claimed in claim 8 further comprising a switch device interacted with the ratchet wheel and configured to releasably stop the ratchet wheel from rotation, and wherein the switch device includes an input control exposed from the engaging head.

10. The clench wrench as claimed in claim 1 , wherein the clenching member is a thin plate that has a substantially smaller thickness than a thickness of the engaging head.

11. The clench wrench as claimed in claim 1 , wherein the engaging head includes a wall disposed above and shielding the clenching member.

12. The clench wrench as claimed in claim 11 , wherein the fixed end of the clenching member and one of the front and back sides of the engaging head and the wall respectively include a hole and a first engaging hole and a first engaging aperture, and wherein a first fastener inserts into the hole and the first engaging hole and the first engaging aperture and fastens the clenching member and the wall on the engaging head.

13. The clench wrench as claimed in claim 12 , wherein one of the front and back sides of the engaging head and the wall respectively include a second engaging hole and a second engaging aperture, and wherein a second fastener inserts into the second engaging hole and second engaging aperture and fastens the wall on the engaging head.

14. The clench wrench as claimed in claim 1 , wherein the clenching member has a main body and includes a lever protruding upwardly from the main body.
