HAND-DRIVEN MECHANICAL SCREWDRIVER

摘要

A hand-driven mechanical screwdriver includes a holding assembly, a drive mechanism supported by the holding assembly, and a working element. The holding assembly includes a bracket and a sliding channel defined in the bracket. The drive mechanism includes a connecting element and a screw rod threadably engaged within the connecting element. An activator is rotatably connected to the connecting element and slidably positioned within the holding assembly bracket sliding channel. The working element is attached to the second end of the screw rod. When the activator is slid along the sliding channel, the connecting element moves from near the second end of the bracket towards the first end of the bracket rotating the threadably engaged screw rod and the working element attached to the screw rod.
