Ratchet wrench, comprising movable head to be controlled with transversally positioned element

摘要

The tool is assembled of a longitudinal handle (10) accommodating several bits and a separate head (20) with a cube-shaped extension (21) for joining one of them. The handle (10) has a central slot (11) at its lower end with two lateral elements serving as a bearing for an extension (22) protruding from the rear of the head (20) and provided with a toothed upper segment (23). A threaded bolt is guided through bores in both parts. The position of the head (20) can be changed after a spring supported pin (33) acting on a spherical element has been pressed.
