Abstract

The locking mechanism including a pair of springs, each spring having a locking pin at one end and being fastened at the other end within the handle of the tool, the two locking pins protruding above the surface of the tool handle and tightly fitting within the two apertures of the tool holder. The locking mechanism also including two activators, each activator having a portion extending outside the tool handle and a portion within the tool handle resting on one of the springs. When the activators are pushed, the springs are forced downward, resulting in the locking pins being moved downward from the surface of the tool handle and out of the apertures of the tool holder, thereby releasing the tool from the tool holder.
