[0029] Each reinforcing component 4 includes an elastic fixing plate 401, a fixing inclined plate 402, a fixing ring 403, and a spring 404. Each elastic fixing plate 401 is located at the bottom of the shock-absorbing mounting port 6 and at the top of the connecting plate body 1. Each elastic fixing plate 401 has a fixing inclined plate 402 on the side away from the connecting plate body 1. Each fixing inclined plate 402 has a fixing ring 403. The inner diameter of each fixing ring 403 is adapted to the outer diameter of the corresponding fixing inclined plate 402. The inner wall of each fixing ring 403 is movably connected to the fixing inclined plate 402 by threads. Rotating the fixing ring 403 makes it gradually approach the connecting plate body 1 on the fixing inclined plate 402. The gradually thickening design of the fixing inclined plate 402 near the connecting plate body 1 makes the elastic fixing plate 401 continuously close and press against the internal shock-absorbing bottom cylinder during the rotation of the fixing ring 403 until the installation and fixation of the connecting plate body 1 and the shock-absorbing bottom cylinder will not be loose.

[0030] Each elastic fixing piece 401 is provided with a spring 404. Each spring 404 is located between the fixing ring 403 and the connecting plate body 1. One end of each spring 404 is fixedly connected to the top of the connecting plate body 1. The size of each spring 404 is adapted to the external size of the corresponding elastic fixing piece 401. When the fixing ring 403 moves closer to the connecting plate body 1, the spring 404 is squeezed, which will give the fixing ring 403 a lateral squeezing force, making the fixing ring 403 itself less prone to loosening.

[0031] Each shock-absorbing mounting port 6 is provided with a shock-absorbing fixing port 7 at its bottom end. Each shock-absorbing fixing port 7 is located at the bottom end of the connecting plate body 1. The shock-absorbing fixing port 7 helps to fix the shock-absorbing bottom cylinder and reduces its compression on the edge of the shock-absorbing mounting port 6.
