[0026] In this embodiment, by providing a fixing mechanism 2, the connecting wire connected to the power supply body 1 can be fixed by clamping. By providing a bidirectional threaded rod 22 and a limit rod 23, and the bidirectional threaded rod 22 can threadably drive the two threaded sleeves 24, the two threaded sleeves 24 can simultaneously move in the same direction and in the opposite direction on the bidirectional threaded rod 22, thereby achieving the purpose of controlling the distance between the clamping block 1 26 and the clamping block 27. At the same time, the clamping block 1 26 and the clamping block 27 can fit with the end of the connecting wire, thereby fixing the end, thereby ensuring the stability of the connection between the connecting wire and the power supply body 1.

[0027] Example 2

[0028] like Figure 1-Figure 3 As shown, an auxiliary mechanism 3 is provided on one side of the fixing mechanism 2, and the auxiliary mechanism 3 includes an elastic rod 31, and the elastic rod 31 is fixedly connected to the clamping block 1 26 and the clamping block 2 27.

At the same time, the sliding sleeve 25 will slide on the limiting rod 23, and the inner diameter ring of the bearing 28 will be driven to rotate by the bidirectional threaded rod 22. , to ensure the stability of the rotation of the bidirectional threaded rod 22, until the clamping block 1 26 and the clamping block 2 27 tightly clamp the end of the connecting line, then align the fixing block 1 32 and the fixing block 2 33, and place the cable of the connecting line between the fixing block 1 32 and the fixing block 2 33, and then pass the two slotted bolts 35 through the fixing block 1 32 and the fixing block 2 33, and threadedly connect them with the nuts 36 until the fixing block 1 32 and the fixing block 2 33 fit together, and under the protection of the rubber pad 34, the cable of the connecting line is tightly fixed. At this time, even if the outside world causes accidental touch to the connecting line and the power supply body 1, it will not cause poor contact between the connecting line and the power supply body 1, or damage to the connecting line.
