The end of the drive rod 10 is fixedly connected with a stepping motor 11, and the stepping motor 11 is fixedly connected with the support frame 3. The drive rod 10 has an L-shaped structure.

[0029] The support mechanism 2 rotatably connected with the measuring instrument body 1 can be designed to be circularly slid inside the sliding frame 9 by the drive rod 10 on the stepping motor 11 during use. Then, the sliding frame 9 is limited by one of the racks 7, so that the rack 7 is driven to move while driving the other two racks 7 through the connecting plate 8. Thus, the rack 7 drives the gear 5 and the support leg 6 thereon to rotate, so that the measuring instrument body 1 can be stably supported. This design can ensure stable support while facilitating transportation and use.
