[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides a serpentine structure that is convenient for the connection and disassembly of the end heads. When the connecting part is assembled with the connecting seat and the head end is assembled with the head end seat, the head end seat is embedded in the interior of the head end, and the connecting seat is embedded in the interior of the connecting part. The card ball is squeezed, so that the connecting block drives the spring to contract and generate elastic force, and then the serpentine structure is twisted. After the card ball is driven by the accommodating box to rotate to the corresponding position with the second positioning hole or the first positioning hole, the elastic force of the spring pushes the connecting block to move, so that the card ball is automatically embedded in the interior of the second positioning hole and the first positioning hole, and then automatically positioned during assembly without the need for staff observation, and the card connection of the card ball improves the stability after positioning, which is beneficial to subsequent assembly operations.
