Abstract:
A fixing device for quickly fastening and releasing a mechanical part that bears on a support base, said device comprising a bayonet latching mechanism and an associated screw-and-nut clamping mechanism organized coaxially with said latching mechanism, the two mechanisms being actuated one after the other by actuating a common rotary drive member in the same direction, wherein the device further comprises temporary coupling means interposed between the drive member and the latching and clamping mechanisms, and organized in such a manner that over a first angle of rotation of the drive member said drive member is constrained to rotate with the latching mechanism, and that over a second angle of rotation of the drive member, said drive member is released from the latching mechanism and is constrained to actuate the clamping mechanism.
