[0036] like Figure 1 , Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a connecting component includes a metal ring 4 fixedly connected to the outer wall of the connecting base 1, a connecting sleeve 41 slidably connected to the outer wall of the connecting base 1, and a threaded groove 42 arranged on the inner wall of the connecting sleeve 41. The connecting sleeve 41 connects the FC jumper head to the device thread through the threaded groove 42, and the metal ring 4 is socketed with the annular groove in the interface to complete the alignment work before the FC jumper head is connected.

[0037] like Figure 2 and Figure 4As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the buffer assembly includes a support frame 5 fixedly connected to the outer wall of the connecting sleeve 41, a shock-absorbing spring 51 fixedly connected to the outer wall of the support frame 5, and an anti-touch sleeve 6 slidably connected to the outer wall of the shock-absorbing spring 51, and the shock-absorbing spring 51 is symmetrically distributed about the central axis of the support frame 5.
