The guide rod 130 is parallel to the screw rod 110, and the mounting block 220 is provided with a guide hole that cooperates with the guide rod 130, and the guide rod 130 passes through the guide hole.

[0039] In one embodiment of the present invention, the number of guide rods 130 is a plurality corresponding to the mounting blocks 220, and each guide rod 130 is correspondingly disposed on each mounting plate 120. The guide rod 130 extends in the axial direction of the screw rod 110 away from the mounting plate 120. Each mounting block 200 is correspondingly penetrated by a guide rod 130. The structure can be referred to Figure 2 As shown, there may be four guide rods 130, mounting blocks 220 and mounting plates 120, and the corresponding connecting rods 300, image collectors 400 and brackets 150 are also four in number and arranged at intervals of 90°.

[0040] In one embodiment of the present scheme, the support assembly 100 also includes an anti-rotation seat 140 and a plurality of brackets 150.

The angle of the inclined surface matches the maximum adjustment angle of the image collector 400. In this solution, the adjustment angle of the image collector 400 can be specifically designed to be 45°±5°, but it is certainly not limited to this.

Specifically, each connecting rod 300 includes two sub-rods, which are respectively located on both sides of the image collector 400 to improve the stability of the structure.

[0044] In one embodiment of the present solution, both ends of the connecting rod 300 are connected to the mounting block 220 and the image collector 400 through fisheye joints of positive and negative threads, respectively, to achieve interlocking and anti-loosening. The first end of the connecting rod 300 is connected to the mounting block 220 through a first fisheye joint, and the middle part of the image collector 400 is hinged to the second end of the connecting rod 300 through a second fisheye joint, and the first fisheye joint and the second fisheye joint are positive and negative threads.
