<p>The fixing device is designed for revolving and permanent fixation of the handle in a specific position. By it, reliable fixation and complete safety is attained during the revolving itself. The device comprises a two-section casing (1) in the front part and on the inner side of which inner teeth (2) and grooves (3) are machined. Teeth (2) are fitted in guiding grooves (4), machined on the basic body (15), guiding teeth (5) are fitted in grooves (3), also machined on the body (15). In predetermined interval on the guiding teeth (5) longitudinal grooves (6) are fabricated, the depth of which is equal to that of the guiding grooves (4). In one of them, the front end of a pivotally fixed plate (7) is found, which at its rear end is supported by the pushed spring (8). Around the middle of the fixing plate (7) a fixed revolving pin (9) is fitted, having a longitudinal hole (10) is found in its free end. In it a guiding pin (11) is fitted, fixed to a pivotally fitted two-arm lever (12), the lower end of which is fitted above a start-up button (14). 1 claim, 3 figures</p> |
