[0016] Further, the top end face and the bottom end face of the fixing plate are fixedly installed with guide blocks, and the guide blocks are slidingly sleeved in the protection shell.

[0017] The beneficial effects of the above further scheme are:

[0018] The sliding cooperation of the guide block and the protection shell provides accurate guiding for the movement of the fixing plate in the protection shell. When installing, disassembling or adjusting the position of the fixing plate, the guide block can ensure smooth sliding of the fixing plate in the predetermined direction, avoid deviation and jamming of the fixing plate, and make the operation process more smooth and convenient. At the same time, this guiding structure helps to maintain the relative position accuracy between the fixing plate and the protection shell, ensures accurate alignment of the first clamping groove and the second clamping groove, and ensures that the alarm wire body can be stably clamped, thereby improving the assembly quality and stability of the entire wire harness structure.
