Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 3, the utility model provides a technical solution for a vertical surveying and mapping support structure that is convenient for fixing: including a fixed disk 1 and a surveying instrument body 101 rotatably installed on the outer top surface of the fixed disk 1. The outer bottom surface of the fixed disk 1 is fixedly installed with ear plate seats 102 arranged at equal intervals in a circumferential manner. The inner sides of the three ear plate seats 102 are rotatably sleeved with a first support arm 103. At the same time, a clamping component 2 capable of quickly disassembling and assembling the first support arm 103 is provided on the outer side walls of the three ear plate seats 102. The clamping component 2 includes a first through hole 201 opened at the top of the outer side walls of the three first support arms 103, and second through holes 202 adapted to the first through hole 201 are opened on the outer side walls of both sides of the three ear plate seats 102. The inner sides of the first through hole 201 and the second through hole 202 are fixedly connected to each other by a first limiting rod 203 inserted together, and one end of the three first limiting rods 203 extends to the outer side wall of the ear plate seat 102 and is fixedly installed with a first square block 204. A return spring 205 is fixedly connected between the first square block 204 and the ear plate seat 102 and located outside the first limiting rod 203. A first pull ring 206 is fixedly installed on the outer side wall of the first square block 204 and away from the ear plate seat 102. First, pull the first pull ring 206 so that the first limiting rod 203 is driven to move horizontally along the inner sides of the first through hole 201 and the second through hole 202 and be pulled out under the connection of the first square block 204, and then the surveying instrument body 101 can be quickly separated from the first support arm 103, and it can be replaced and transported according to different environments. At the same time, release the first pull ring 206, and under the action of the return spring 205, the first limiting rod 203 can re-fix the first support arm 103 and the surveying instrument body 101, simplifying the disassembly and assembly steps, thereby improving the work efficiency of replacement and fixing, and being beneficial to long-term use and promotion.

[0024] The outer wall of the three groups of first support arms 103 is provided with a sliding groove 104, and the interior of the sliding groove 104 is fixedly connected with the second support arm 105 through an extension component 3. The extension component 3 includes first limiting holes 301 arranged vertically and evenly spaced on the inner wall of the sliding groove 104, and second limiting holes 302 adapted to the first limiting holes 301 are provided on the outer wall of the second support arm 105. The first limiting holes 301 and the second limiting holes 302 are connected to each other by a second limiting rod 303 inserted together. The support arms 105 are fixed to each other, one end of the three second limiting rods 303 extends to the outer wall of the second support arm 105 and is fixedly installed with a second block 304, and a second pull ring 305 is fixedly installed on the outer wall of the second block 304. A connecting seat 306 is rotatably installed on the outer bottom surface of the three groups of second support arms 105, and an annular latch 307 is fixedly installed at the center position of the outer bottom surface of the connecting seat 306. Grooves 308 are provided at equal intervals on the outer peripheral side walls of the three groups of connecting seats 306, and a support plate 309 is rotatably installed on the inner side of the groove 308. When the surveying instrument body 101 is transported to the designated location, the annular latch 307 at the bottom of the connecting seat 306 is fixedly inserted into the soil ground, and then the supporting plate 309 is rotated from the groove 308 and placed horizontally to stably fix the connecting seat 306 at the designated location, so that the first support arm 103 and the second support arm 105 can provide stable support and fixation for the surveying instrument body 101 to prevent the surveying instrument body 101 from tipping over. At the same time, when the second pull ring 305 is pulled to remove the second limiting rod 303 from the first limiting hole 301 and the second limiting hole 302, the second supporting arm 105 can slide and extend inside the sliding groove 104, thereby raising the height of the surveying instrument body 101, so that the height of the surveying instrument can be adjusted in time according to the on-site conditions, which is conducive to improving the flexibility and practicality of the device in actual use.

[0025] The working principle of the utility model is as follows: when in use, the surveying instrument body 101, the first support arm 103 and the second support arm 105 are first transported to the designated positions in sequence, and then the first limiting rod 203 fixes the first support arm 103 and the ear plate seat 102 to each other, thereby connecting the surveying instrument body 101 to the first support arm 103, and then pulls the first support arm 103 to expand it outward, and allows the annular clamping teeth 307 on the second support arm 105 to be fixedly inserted on the soil ground, and then the support plate 309 is rotated from the groove 308 and placed horizontally to stably fix the connecting seat 306 at the designated place, providing a stable support and fixing effect for the surveying instrument body 101 while limiting and fixing the surveying instrument body 101.

[0026] Meanwhile, when it is necessary to replace different surveying instruments, directly pull the first pull ring 206, so that under the connection of the first square block 204, the first limiting rod 203 is driven to move horizontally along the inner sides of the first jack 201 and the second jack 202 and pulled out. Then, the surveying instrument body 101 can be quickly separated from the first support arm 103 and replaced. Then, under the action of the return spring 205, the replaced surveying instrument body 101 can be fixed again. This simplifies the disassembly and assembly steps, improves work efficiency, and during the replacement process, the support structure always ensures a stable fixed state, avoiding the trouble of subsequent re-fixing.

[0027] Meanwhile, when pulling the second pull ring 305 to take out the second limiting rod 303 from the first limiting hole 301 and the second limiting hole 302, the second support arm 105 can be made to slide and extend inside the sliding groove 104, so as to lift the height of the surveying instrument body 101, enabling the height of the surveying instrument to be adjusted up and down in a timely manner according to the on-site situation.

[0028] Finally, after use, the surveying instrument body 101 can be separated from the first support arm 103 again and transported separately according to needs, thereby reducing the possibility of damage to the surveying instrument body 101 during transportation.

[0029] The above is only the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
