[0026] It also includes a first welding groove 17 and a second welding groove 18. The first welding groove 17 is arranged at a corresponding position on the anti-theft lock flange 5, the rotating track flange 6 and the rotating lock flange 7. The second welding groove 18 is arranged at a corresponding position on the bottom of the side of the outer protective shell 1 and the upper part of the side of the rotating lock 8.

[0027] The device position is locked and fixed by the locking device; the locking device is automatically reset by the resetting device, so that the device has the ability to automatically lock after connection, reducing the situation of forgetting to lock, and the rotation position of the rotary lock 8 is limited by rotating the limit block 16, which makes it easy for the locking device to quickly find the locking position, thereby improving the practicality of the device.

[0028] Compared with the locking device and resetting device involved in the cited patent (CN202020685911.3), the locking device and resetting device in this patent are significantly different from the structure of this patent. The locking device and resetting device in this patent have obvious installation and disassembly advantages, and the anti-theft lock hole 2 in the above-mentioned patent is less adaptable than the limit lock hole 15 in this case. Therefore, the claims in this patent do not involve infringement of the cited patent (CN202020685911.3).

[0029] The above is only a preferred embodiment of the present invention.
