DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0016] Embodiment: As Figures 1-3As shown in the figure, the utility model provides a positioning type cadastral surveying and mapping device, which includes a support ring 1. A bottom plate 11 is fixedly installed inside the support ring 1. Symmetrically distributed support rods 12 are fixedly installed at the bottom end of the bottom plate 11. A movable plate 13 is detachably installed on the outer side of the support rods 12. Symmetrically distributed fixed rods 14 movably penetrate through the top end of the movable plate 13. An installation plate 15 is fixedly installed at the top of the fixed rods 14. Symmetrically distributed rotating rods 16 are rotatably arranged above the movable plate 13. Symmetrically distributed inclined plates 17 are fixedly installed on the outer side of the rotating rods 16. A first jacking plate 18 is fixedly installed at the bottom end of the inclined plate 17. The first jacking plate 18 and the installation plate 15 are used in cooperation. A second jacking plate 19 is fixedly installed at the top end of the inclined plate 17.

[0017] Symmetrically distributed fixed blocks 2 are fixedly installed on the outer side of the movable plate 13. A vertical rod 21 is fixedly installed at the top end of the fixed block 2. A movable plate 22 is movably sleeved on the outer side of the vertical rod 21. The movable plate 22 and the two fixed blocks 2 are fixedly connected by a first spring 23. A T-shaped plate 24 is fixedly installed at the top end of the movable plate 22. Symmetrically distributed connecting plates 25 are fixedly installed at the bottom of the T-shaped plate 24. The T-shaped plate 24 and the connecting plates 25 are both used in cooperation with the second jacking plate 19.

[0018] Symmetrically distributed second springs 3 are fixedly installed at the bottom end of the movable plate 22. The other end of the second spring 3 is fixedly connected with the movable plate 13. By setting the second spring 3, the reset speed of the movable plate 22 is improved.

[0019] Evenly distributed anti-slip blocks 4 are fixedly installed at the top end of the T-shaped plate 24. By setting the anti-slip blocks 4, the stability of the staff's pressing is improved.

[0020] Thread grooves 5 are opened at the bottom of the support rods 12. The top end of both sides of the movable plate 13 rotatably penetrates through sleeves 51. The sleeves 51 are threadedly sleeved on the bottom of the support rods 12. By setting the thread grooves 5, the sleeves 51 can be taken out from the support rods 12, which is convenient for disassembling the movable plate 13.

[0021] Two groups of symmetrically distributed support blocks 6 are fixedly installed at the top end of the movable plate 13. The rotating rods 16 rotatably penetrate through the corresponding support blocks 6. By setting the support blocks 6, the rotating rods 16 can be supported to rotate smoothly.

[0022] Annularly distributed connecting blocks 7 are fixedly installed on the outer side of the support ring 1. Inclined rods 71 are movably arranged at the bottom end of the connecting blocks 7. By setting the connecting blocks 7 and the inclined rods 71, the stability of the support ring 1 is improved, and thus the stability of the measuring instrument is improved.

[0023] The number of the second springs 3 is three, which can reduce the pressure borne by the first spring 23 and increase the service life of the first spring 23 and the second spring 3 at the same time.

[0024] Working principle: In actual use, place the support rod 12 in a suitable position, and then insert the fixing rod 14 into the movable plate 13. The staff makes the fixing rod 14 insert into the ground by stepping on it with feet or with the aid of tools, providing stability for the movable plate 13 and the support rod 12. When it is necessary to remove the fixing rod 14, apply pressure to the T-shaped plate 24 in the direction of the movable plate 13 to drive the T-shaped plate 24 to descend. At this time, the T-shaped plate 24 drives the second jacking plate 19 and the moving plate 22 to descend, so that the second jacking plate 19 drives the inclined plate 17 to rotate with the rotating rod 16 as the fulcrum. At this time, the first jacking plate 18 rises, thereby driving the mounting plate 15 to rise, so that the fixing rod 14 is pulled out of the ground. During the descending process of the moving plate 22, it can apply pressure to the first spring 23 to cause it to deform. When the pressure on the T-shaped plate 24 is stopped, the first spring 23 releases its elastic force, driving the moving plate 22 and the T-shaped plate 24 to rise. At the same time, the T-shaped plate 24 drives the second jacking plate 19 to rise through the connecting plate 25, so as to be able to reset the second jacking plate 19, facilitating the next use by the staff.

[0025] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
