The first extension plate 5314 and the second extension plate 5315 are disposed opposite to each other, and a guide groove 5316 is provided between the first extension plate 5314 and the second extension plate 5315. The clip sub-portion 5332 can gradually approach the grip portion 531 along the guide groove 5316, and finally the clip 5312 can be clipped into the connection hole 5333.

It can be understood that, during the clamping process, the clamp 5312 and the clamp portion 5332 need to be elastically deformed, and when the clamp portion 5332 cannot be rebounded due to excessive elastic deformation, there may be assembling failures such as clamping failure or clamping dislocation. In order to prevent the clamping portion 5332 from being deformed excessively and thus not clamped. The second extension plate 5315 may extend in a direction away from the connecting portion 533, such that the second extension plate 5315 is disposed opposite to the buckle 5312. It can be understood that the second extension plate 5315 is disposed opposite to the clip 5312, so that the deformation of the clip portion 5332 can be limited when the clip portion 5332 is clipped to the clip 5312, and the situation of failure to clip or misplacement of clipping can be avoided.

In order to avoid poor installation, the clamping condition of the clamping position needs to be confirmed in time in the clamping process. The clip portion 5332 has an opening 5319, and the opening 5319 is disposed opposite to the protrusion 5318 of the clip 5312 to observe the clipping condition between the clip 5312 and the clip portion 5332.
