[0023] When the fixing device of the surveying instrument designed by the present invention is used, the connecting block 31 provided at the bottom of the connecting plate 1 is inserted into the connecting groove 32 to preliminarily connect the connecting plate 1 and the support plate 21. Because the connecting block 31 includes the first connecting portion 311 and the second connecting portion 312, and the second connecting portion 312 is set to be an isosceles trapezoid, and the moving block 33 is provided with a wedge-shaped surface that fits the second connecting portion 312, as the connecting block 31 is gradually inserted, the moving block 33 will be squeezed first. At this time, the connecting block 31 will press the provided first buffer spring. As the moving block 33 gradually moves downward, when the compressed moving block 33 is level with the plug-in groove 35 provided on the first connecting portion 311, the compressed first buffer spring will push the moving block 33, causing the moving block 33 to move into the plug-in groove 35, stably connecting the connecting block 31 and the support plate 21. No bolts are required during the entire installation process, which makes the installation more convenient and quick, thereby improving the work efficiency of the construction workers.

[0024] Preferably, Figures 1 to 3 As shown, a driving assembly 4 is provided on one side of the support plate 21, and the driving assembly 4 includes a pair of moving rods 41, an extrusion rod 42, a second return spring 43 and a pair of hinged rods 44. The pair of moving rods 41 are arranged in a one-to-one correspondence with the pair of moving blocks 33. One end of the pair of moving rods 41 passes through the support plate 21 and is slidably connected to the support plate 21. The sliding direction of the moving rod 41 is consistent with the moving direction of the moving block 33. The axis of the extrusion rod 42 is horizontally set and is perpendicular to the axis of the connecting block 31.

A pair of hinged rods 44 are arranged in a one-to-one correspondence with the pair of moving rods 41. One end of the hinged rod 44 is fixedly connected to the moving rod 41, and the other end is fixedly connected to the extrusion rod 42.

[0025] In the present invention, a driving assembly 4 is provided on one side of the support plate 21 for use in conjunction with the connecting assembly 3. When the surveying instrument body 8 needs to be separated from the fixed bracket body 2, it is only necessary to press the provided squeezing rod 42 to squeeze the provided second spring. When the squeezing rod 42 moves toward the side of the support plate 21, the moving rod 41 is hinged to the squeezing rod 42 through the hinge rod 44. At this time, the moving rod 41 will move away from the connecting block 31. Since the moving rod 41 is slidably provided on the support plate 21 and connected to the moving block 33, the moving rod 41 will pull the provided moving block 33 to be pulled out of the insertion slot 35. In the present invention, hinge rods 44 are provided on the opposite sides of the extrusion rod 42, so that a pair of moving rods 41 drive their respective moving blocks 33 to move away from each other, thereby pulling out the two moving blocks 33 from their respective plug-in slots 35. At this time, the construction personnel only need to lift the connecting plate 1 to complete the separation of the surveying instrument body 8 and the fixed bracket body 2. It is convenient and quick to use. When the separation is completed, the squeezed second buffer spring will push the extrusion rod 42 back to its original position, and the moving rod 41 will drive the moving block 33 to return to its original position to facilitate the next installation and use of the surveying instrument body 8 and the fixed bracket body 2.

[0026] Preferably, the second connecting portion 312 is completely matched with the connecting groove 32, the movable block 33 is fixedly connected to the first telescopic rod 5 at one end away from the connecting block 31, one end of the first telescopic rod 5 is fixedly connected to the support plate 21, the first return spring 34 is sleeved on the first telescopic rod 5, one end of the extrusion rod 42 is fixedly connected to the second telescopic rod 6, and the second return spring 43 is sleeved on the second telescopic rod 6.

[0027] In the present invention, the second connecting portion 312 is completely matched with the connecting groove 32, which prevents the connecting block 31 from shaking after connection, further improving the connection stability between the connecting plate 1 and the support plate 21, and stably guides the first buffer spring through the first telescopic rod 5, and stably guides the second buffer spring through the second telescopic rod 6.

[0028] Preferably, Figures 1 to 3 As shown, the fixed bracket body 2 also includes a support column 22, a bearing disc 23 and a limiting rod group 24. The support column 22 is vertically fixedly connected to the bottom of the support plate 21. The support column 22 is arranged on the bearing disc 23. A number of limiting rod groups 24 are provided, and a plurality of limiting rod groups 24 are arrayed and hinged to the circumference of the bearing disc 23. The limiting rod group 24 includes a first support rod 241, a second support rod 242, a limiting plate 243 and a limiting anchor rod 244. The first support rod 241 is tilted and one end is hinged to the bearing disc 23. The second support rod 242 is slidably inserted into the first support rod 241. The first support rod 241 and the second support rod 242 are limited by the limiting member 7. The second support rod 242 is hinged to the limiting disc. A plurality of limiting anchor rods 244 are vertically arranged at the bottom of the limiting disc. A spirit level 9 is embedded in the top of the support plate 21.

[0029] In the present invention, the supporting disc 23 is supported by the limit rod group 24, and the supporting disc 23 supports the support plate 21 through the support column 22 provided on the top, and the limit assembly array in the present invention is hinged to the circumference of the supporting disc 23, further improving the overall stability of the fixed bracket body 2. The inventor found in actual application that the traditional fixed bracket is not convenient for reasonable adjustment according to the actual situation of the surveying and mapping area, resulting in the tilting of the support plate 21, which in turn causes the surveying instrument body 8 installed on the support plate 21 to be in a tilted state, resulting in deviations in the data measured by the surveying instrument. The second support rod 242 of the present invention is slidably arranged in the first support rod 241, and the second instrument support rod is also hinged to the supporting disc 23. According to the actual support situation, it is only necessary to adjust the depth of the second support rod 242 inserted into the first support rod 241. When used together with the supporting disc 23 and the limit disc, observing the spirit level 9 provided on the support plate 21 can ensure that the support plate 21 is in a horizontal state, thereby ensuring the accuracy of the data measured by the surveying instrument.

[0030] Preferably, Figures 1 to 3 As shown, the limiting member 7 includes a limiting screw 71, and a plurality of limiting holes 72 are opened on the first support rod 241 and the second support rod 242 along the sliding direction of the second support rod 242. A nut 73 is sleeved on the limiting screw 71, and the top of the connecting plate 1 is fixedly connected to the surveying instrument body 8.

[0031] When adjusting the second support rod 242, pull the set second support rod 242 to adjust it to the appropriate position, then pass the limiting screw 71 through the first support rod 241 and the second support rod 242 in sequence, and then screw the nut 73 onto the limiting screw 71 to complete the limiting of the second support rod 242 and the first support rod 241, ensuring that the limiting assembly provides stable support for the supporting disc 23.

[0032] The method of using the engineering surveying and mapping instrument fixing device of the present invention is as follows:

[0033] According to the position to be surveyed, first pull the second support rod 242, pass the limiting screw 71 through the first support rod 241 and the second support rod 242 in sequence, and then screw the nut 73 on the limiting screw 71 to complete the limiting of the second support rod 242 and the first support rod 241. After adjusting the multiple groups of limiting rods 24, observe the level 9 provided on the support plate 21 to ensure that the support plate 21 is in a horizontal state;

[0034] When the cam 33 is in the unlock state, the locking cam 33 is unlocked and the locking cam 33 is unlocked, so that the cam 33 can be unlocked and the master lock 33 is unlocked.

[0035] When the surveying and mapping work is completed, the extrusion rod 42 is pressed to squeeze the second spring. When the extrusion rod 42 moves toward the side of the support plate 21, the moving rod 41 is hinged to the extrusion rod 42 through the hinge rod 44. At this time, the moving rod 41 moves away from the connecting block 31. Since the moving rod 41 is slidably arranged on the support plate 21 and connected to the moving block 33, the moving rod 41 will pull the moving block 33 out of the insertion slot 35. In the present invention, by arranging hinge rods 44 on the opposite side of the extrusion rod 42, the moving rod 41 will move to the side away from the connecting block 31. , so that the pair of moving rods 41 drive their respective moving blocks 33 to move away from each other, thereby pulling the two moving blocks 33 out of their respective plug-in slots 35. At this time, the construction personnel only need to lift the connecting plate 1 to complete the separation of the surveying instrument body 8 and the fixed bracket body 2. It is convenient and quick to use. When the separation is completed, the squeezed second buffer spring will push the squeezing rod 42 back to its original position, and the moving rod 41 will drive the moving block 33 to return to its original position to facilitate the next installation and use of the surveying instrument body 8 and the fixed bracket body 2.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
