It can be understood that, a side of the abutting part 313 of the first limiting part 31 facing the video collector 50 is provided with an elastic cushion block, and a limiting groove is formed on the elastic cushion block to buffer the abutting pressure of the first limiting part 31 on the video collector 50, and simultaneously maintain the integrity of the outer surface of the video collector 50 in the first direction. To improve the stability of the first limiting member 31, the first limiting member 31 is provided with two telescopic rods 311 and two first elastic members 312, one first elastic member 312 is sleeved on one telescopic rod 311, one end of each telescopic rod 311 facing the interface 20 is connected to the abutting member 313, and the two telescopic rods 311 are arranged in parallel. The cover plate 12 in any of the above embodiments is provided with heat dissipation holes 12A to dissipate heat from the space in the interior 11.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
