| 摘要 |
The invention relates to a fixing device for quickly fastening and releasing a mechanical part that bears on a support base, the device comprising a latching mechanism of the bayonet type and an associated clamping mechanism of the screw-and-nut type that is organized coaxially therewith, the mechanisms being actuated one after the other by actuating a common rotary drive member in the same direction, and the device having a temporary coupling means interposed between that member and the mechanisms so that over a first angle of rotation of the drive member said drive member actuates the latching mechanism, and then over a second angle of rotation, said drive member is uncoupled from the latching mechanism and actuates the clamping mechanism.
