The first rod 300 is slidably engaged with the first substrate 100 along the axial direction of the first rod 300. The second rod 400 is fixedly connected to the second substrate 200.

A bearing platform 410 is disposed at an end of the second rod 400 close to the first rod 300, and a grounding end 420 is disposed at an end of the second rod 400 far from the first rod 300.

The height of the positioning sleeve 800 can be adjusted by matching the first extension arm 810 of the positioning sleeve 800 with the first hook 510 with different heights, so that the stability of the first rod body 300 is improved. When the mounting height of the bearing table 410 is different, the sliding distance of the first rod 300 is different, and the position of the positioning sleeve 800 is adjusted, so that the positioning sleeve 800 can better improve the stability of the first rod 300.
