[0041] like Figures 1 to 6 As shown, an embodiment of the utility model provides a microscope stand, including a lifting platform 100, a first horizontal arm 200, a ball 300, an elastic member 400, a first locking member 500, a second horizontal arm 600, a connecting arm 700, a lifting rod 800 and a base 900.

[0042] Among them, the lifting rod 800 is vertically arranged and movably connected with the lifting platform 100 up and down. A third locking member 810 is arranged on the side wall of the lifting platform 100. The lifting platform 100 can be limited on the support rod through the third locking member 810, that is, the height can be adjusted up and down through the lifting platform 100. Specifically, the third locking member 810 is a hand screw. Further, the lower end of the support rod is clamped with the base 900, and the base 900 is fixed on the object.
