[0025] Specifically, before using this combined structure, the microscope's swing arm needs to be fixed to the support rod 4, and the sliding assembly 3 is matched with the bearing assembly 2, so that the push-pull rod 31 can be pushed and pulled smoothly in the bearing assembly, thereby facilitating the microscope to be pulled closer or further away; at the same time, the block 33 can be used to prevent the push-pull rod 31 from being pulled to the end and disengaging from the bearing assembly 2.

[0026] The bearing assembly 2 includes a bearing member and a first adjusting screw 24. The bearing member is slidably mounted on the main bracket 1. The first adjusting screw 24 is arranged on the rear side of the bearing member. The tightness of the bearing member can be controlled by the first adjusting screw 24, so as to facilitate the upward and downward movement of the position of the bearing member on the main bracket 1. The push-pull rod 31 is slidably arranged in the bearing member; when the position of the bearing member on the main bracket 1 is adjusted up and down, the height of the push-pull rod 31 can be indirectly adjusted, and then the height of the support rod 4 connected to the push-pull rod 31 can be indirectly adjusted.

[0027] Reference Figure 5 The bearing component includes a first bearing block 21, a second bearing block 22 and a plurality of bearing limit columns 23. The first bearing block 21 is fixedly connected to the second bearing block 22, and the middle part of the connection is respectively recessed inward to form a sliding channel 25. The plurality of bearing limit columns 23 are arranged in two rows and symmetrically arranged on the inner side walls of the sliding channel 25 on both sides.
