[0025] The left and right ends of the mounting plate 1 are both hinged with support columns 11, and the mounting plate 1 is fixed by the support columns 11. The support columns 11 are arranged with the inner side higher and the outer side lower. A cone head 12 is arranged at the lower end of the support column 11, and the cone head 12 is used to facilitate the insertion of the support column 11. The upper surface of the box body 2 is recessed downward to form a slide groove with a circular structure, and the slide groove is used to provide a movable space for the slider 41. The slide groove is arranged on the outer side of the circular rod 5, and a plurality of sliders 41 are equidistantly arranged at the lower end of the surveying and mapping instrument body 4. The slider 41 is used to guide the surveying and mapping instrument body 4.

The movement of the slider 41 is facilitated by the bull's eye ball 42, and the rolling part of the bull's eye ball 42 fits with the bottom end of the inner part of the slide groove.

[0026] When in use, first move the surveying and mapping instrument body 4 to a suitable position, then place the support column 11 on the ground, and press the support column 11 so that the support column 11 is inserted into the specified position, thereby fixing the surveying and mapping instrument body 4. When it is necessary to fine-tune the surveying and mapping instrument body 4, first hold the handle 9, and then turn the handle 9 to rotate the disc 8 connected to the handle 9, and then rotate the worm 6 connected to the disc 8.

[0027] See also Figure 2 , Figure 3 and Figure 4 A cylinder 21 is arranged at the front end of the box body 2, and the cylinder 21 provides an installation space for the circular plate 23. The circular plate 23 is slidably arranged in the cylinder 21, and the circular plate 23 is used to realize the movement of the round rod 24. The inner rear wall of the cylinder 21 is equidistantly arranged at one end of a plurality of elastic members 22, and the elastic member 22 can be a spring, and the circular plate 23 is rebounded by the spring. The other end of the elastic member 22 is connected to the circular plate 23. A round rod 24 is arranged at the front end of the circular plate 23, and the round rod 24 is used to squeeze the disc 8.

[0028] When in use, the vertical plate 26 is first pushed backward, so that the vertical plate 26 and the round rod 24 move backward under the action of the thrust, and then the round plate 23 connected to the round rod 24 moves backward. In the process of the circular plate 23 moving backward, the elastic member 22 arranged at the rear end of the circular plate 23 is squeezed, so that the elastic member 22 generates an elastic force, and then the disc 8 rotates. When the disc 8 rotates to a suitable position, the thrust on the vertical plate 26 is released, so that the circular plate 23 moves forward under the action of the elastic force, and then drives the round rod 24 to move forward, and at the same time makes the round rod 24 contact with the disc 8, thereby squeezing the disc 8, and then the anti-skid pad 25 arranged at the front end of the round rod 24 contacts the anti-skid groove opened at the rear end of the disc 8.
