PURPOSE: To provide an apparatus capable of being mounted or dismounted, such as assembled or removed quickly and easily, used repeatedly, maintained in right position when mounted or dismounted, and locked in an ensured way. CONSTITUTION: The apparatus comprises a first connecting member 1 and a second connecting member 2 having a first member and a second member. When assembled, the two connecting members 1, 2 are first engaged with each other along an engaging shaft. A fixing element 13 of the first connecting member 1 is inserted into a receiving element 23 of the second member 2 by the engagement. The apparatus further comprises a cylindrical sliding element i.e., a tube 3 having a returning spring 12 separating the first connecting member 1 from the second connecting member 2, and playing a pressurizing function for holding the inserted fixing element 13 in the receiving element 23. The tube 3 has a built-in spring 4 for connecting and locking the fixing element 13 and the receiving element 23 in a secured way, as well as a rod 35 for cooperating with the spring 4 to unlock by exerting and releasing pressurizing on the rod 35. The fixing and receiving elements 13, 23 have complimentary shapes. |
