| 摘要 |
The invention concerns a fixing device for angular positioning by fast rotation, comprising a toothed base plate (2) fixed on a snowsurf board surface (20) by means of a screw passing through a cap (3) maintaining a plate (1) in free rotation. It is maintained in fixed angular horizontal position by engagement of a lever (4) provided with toothing (10) matching the base plate (2) toothing (7). By exerting pressure on the control member (11) the plate (1) is unlocked thereby becoming free to rotate about the axis (24). |
