Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1 to 2 , the present invention provides a technical solution: a total station that can be placed on various grounds, including a leveling seat 1 , a telescopic rod 2 , a support plate 3 and a total station body 4 . The leveling base 1 is provided with a fixed support foot 7 and two movable support feet 8. The top of the fixed support foot 7 is welded with the leveling base 1, and the fixed support feet 7 and the movable support feet 8 are evenly distributed in a ring with the leveling base 1 as the center. 8. After penetrating the leveling seat 1, it is fixedly connected with the movable rod 9, and the leveling seat 1 is bolted to connect the guide cylinder 10. The guide cylinder 10 is sleeved and slidably matched with the movable rod 9. The side wall of the guide cylinder 10 is threadedly connected to the bolts of the first adjusting bolts 11 . The first adjusting bolts 11 are bolts with handles, and the handles are round cakes with anti-slip textures. By rotating the first adjusting bolt 11 so that the bolt is squeezed with the movable rod 9 , the first adjusting bolt 11 can fasten and loosen the movable rod 9 , and the height of the movable leg 8 extending from the leveling seat 1 can be adjusted. The movable rod 9 penetrates through the top of the guide cylinder 10 and is fixedly connected to the pedal 13.
