When the signal transmission line and the signal input head 7 need to be connected, it is only necessary to insert the docking ring 10 into the outer surface of the signal input head 7, and put the docking head 17 on the outer surface of the connecting bolt 6. In this process, the movable ring 18 is pushed by the support spring 22 to move to the end of the outer surface of the docking ring 10 close to the signal input head 7, so that the card bolt 20 can be inserted into the card hole 8, so that the docking ring 10 can be installed on the outer surface of the signal input head 7. When the signal transmission line is to be disassembled, it is only necessary to pull the movable ring 18 on the outer surface of the docking ring 10 to compress the support spring 22 through the slider 24. In this process, the guide block 21 is squeezed to compress the support assembly 16, and the clamping bolt 20 can be pulled out from the inside of the clamping hole 8 and stored in the inside of the support assembly 16, thereby releasing the restriction between the docking ring 10 and the signal input head 7. After that, it is only necessary to easily pull the docking ring 10 to remove it from the signal input head 7.
