| 摘要 |
The invention concerns a device for connecting two parts in two different manners, - a flexible manner with an elastic suspension (3b), - a rigid manner by means of levers (4a) linked to one of the parts (2), resting on a stop (5) of the part, and co-operating with the part (1) by a V(6a) and a pressing element (7a, 14) coupled with the part (1) which thrusts the parts against their stop. The force of the element (14) defines a threshold of rigidity beyond which the connection becomes flexible again.
