[0036] For example, the existing back clip structure of the walkie-talkie adopts direct pins. After the user uses it for a period of time, the direct pins fall off, the back clip function fails, and the product is damaged and cannot be used, resulting in functional failure. After the direct pins are replaced with the stop and positioning pins 1, the pins add the stop and positioning functions without changing the assembly space and the original structure, solving the problem of the pins falling off during product use, eliminating product functional hazards, and improving the customer's product experience satisfaction.
