ABSTRACT:
A positionable screwdriver includes a first housing member, a second housing member pivotally connected with the first housing member, and a positionable mechanism arranged between the first and second housing members. The positionable mechanism has a locking button, a leaf spring, a positioning block, a retaining member, and a spring. The positioning block is formed with a plurality of radial teeth and fixed to the first and second housing members. The locking button is arranged within the second housing member and positioned over the leaf spring. A top of the locking button is provided with a raised portion extending upwardly through an opening of the second housing member. The spring has an end bearing against another end of the locking button so as to keep the locking button positioned over the leaf spring, thereby keeping engagement between the leaf button and the positioning block.
