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.

Please refer to FIGS. 1 to 4 , the present utility model provides a technical solution for an adjustable surveying and mapping instrument bracket: an adjustable surveying and mapping instrument bracket, comprising a fixed disc 1 , an outer strut 4 , an inner strut 5 and a pin 12. A shaft seat 2 is fixedly installed on the bottom surface of the fixed disc 1, and a shaft rod 3 is fixedly installed inside the shaft seat 2. Through the cooperation of the shaft seat 2 and the shaft rod 3, the outer support rod 4 can be rotatably connected and installed inside. , to achieve the effect of rotating and installing the outer support rod 4 and the inner support rod 5, the surface of the shaft rod 3 is rotatably connected with the outer support rod 4, the two sides of the outer support rod 4 are internally provided with a chute 10, and the inside of the chute 10 slides There is a pulley 9, through the cooperation of the pulley 9 and the chute 10, the inner strut 5 can slide inside the outer strut 4, so as to achieve the effect of limited sliding to facilitate the extension and shortening of the inner strut 5, the pulley 9 is rotated and installed On both sides of the inner strut 5, and the inner strut 5 is inserted in the middle of the outer strut 4, through the cooperation of the outer strut 4 and the inner strut 5, the surveying and mapping instrument installed on the top surface of the fixed disk 1 can be stably placed, To achieve the effect of extending or shortening according to the current terrain, one end of the outer support rod 4 is fixedly installed with a limit sleeve 6, and the inner support rod 5 is inserted into the limit sleeve 6.
