Abstract
A wrench with clamping functions is disclosed. The wrench includes a main body, a forcing jaw, a restraining jaw, and a clamping device disposed on the restraining jaw. The main body has an extending direction. The end of the forcing jaw is further from the main body than the end of the restraining jaw along the extending direction. The clamping device includes an elastic member and a block supported by the elastic member and protruded towards a forcing surface of the forcing jaw. When the block is pressed by an exterior force from a workpiece, the block can be partially pushed back into a space of the restraining jaw. On the other hand, the block returns to the origin position if the exterior force is removed, and the workpiece is clamped by the protruded block and the forcing jaw.
