Abstract
A clench wrench has a structure including a handle and an engaging head. The engaging head defines an engaging space. A clenching device is mounted on the engaging head. The clenching device includes a resilient clenching member fixed to the engaging head and having a free end. The clenching member has a clenching portion at the free end. The free end of the clenching member is bendable to selectively clench an object. A block is disposed on the engaging head and abuts against the clenching member and counteracts a force that causes the clenching portion to move from the first position to the second position.
Claims11
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 respectively, wherein the engaging head defines an engaging space for receiving the object engaged with 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 and includes the engaging space extending through the front and back sides and defining an opening in each of the front and back sides;
- a clenching device configured for clenching the object mounted on the engaging head, wherein the clenching device includes a resilient clenching member having a fixed end fixed to the engaging head and a free end, wherein the clenching member has a clenching portion at the free end, wherein the free end of the clenching member is bendable such that the clenching portion is operably movable in a first mode located at a first position and capable of clenching the object received by the engaging space, and a second mode disposed away from the engaging space and located at a second position and capable of letting the object engaged in the engaging space of the engaging head disengage therefrom;
- and
- a block disposed on the engaging head and abutting against the clenching member and counteracting a force that causes the clenching portion to move from the first position to the second position,
- wherein the clenching member has a middle portion, which is bendable, located between the fixed end and the free end, and wherein the block abuts against the middle portion, wherein the middle portion and the fixed and free ends, in a lateral direction, each has a cross-sectional area, and the cross-sectional area of the middle portion is smaller than the cross-sectional areas of the respective fixed and free ends.
