[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The provided insert block, storage slot, first spring, buckle, slot and card slot provide convenience for the installation and disassembly of the device, making it more time-saving and labor-saving during maintenance. The fixation can be completed by simply inserting the insert block into the slot and snapping the buckle into the slot.

[0013] 2. The top plate and the second spring provide convenience for disassembly of the device. When the plug is inserted into the slot, the top plate will be squeezed, thereby compressing the second spring. During disassembly, the buckle is pressed, and the top plate will push the plug out of the slot under the reaction force of the second spring to complete the disassembly.
