Specifically, one end of the elastic element 97 abuts against the first limiting element 91, the second limiting element 93 or the third limiting element 95, and the other end abuts against the abutting seat 77. In this embodiment, the two elastic members 97 respectively push against two opposite ends of the third limiting member 95, so that the third limiting member 95 is connected to the first limiting member 91 and the second limiting member 93 in a limiting manner. Alternatively, the elastic member 97 may be a spring or an elastic sleeve or the like having elasticity.
