The triangular prism block 3 and the device observation point are in the same vertical plane and are used for initially finding the observation point; The main protection component 4 includes a sliding block 401. The sliding block 401 is slidably installed in the installation frame 2. One end of the sliding block 401 is installed with a connecting frame 409. A protection frame 405 is installed on the side of the connecting frame 409 away from the sliding block 401. A V-shaped elastic piece 407 is installed on the side of the sliding block 401 away from the connecting frame 409. Clamping blocks 408 are installed on both sides of the V-shaped elastic piece 407. Two clamping grooves 7 are opened on both symmetric sides of the installation frame 2, and the clamping blocks 408 are clamped in the clamping grooves 7; The auxiliary protection component 5 includes a plug-in block 501 and a protection net 504. The inner cavity side wall of the protection frame 405 is installed with a protection net 504, and an elastic ring 508 is arranged on the protection net 504; The plug-in blocks 501 are symmetrically inserted into the front side of the surveying instrument body 1. Connecting ropes 503 are symmetrically installed on the side walls of the plug-in blocks 501. One side of the connecting rope 503 away from the plug-in block 501 is connected to the elastic ring 508; Among them, during the process of the sliding block 401 and the protection frame 405, the connecting rope 503 will pull the elastic ring 508, so that the elastic ring 508 is stretched to avoid the protection net 504 blocking the observation line of sight of the surveying instrument body 1.

[0021] In a further embodiment, referring to Figure 1 - Figure 7 , connecting plates 402 are respectively installed at both ends of the V-shaped elastic piece 407, and a fixing plate 403 is installed in the middle of the V-shaped elastic piece 407; Among them, the clamping block 408 is clamped in the clamping grooves 7 at different positions to realize the position adjustment of the sliding block 401, the connecting frame 409 and the protection frame 405.

[0022] In a further embodiment, referring to Figure 1 - Figure 7 , plug-in grooves 8 are symmetrically opened on the front side of the surveying instrument body 1, and grooves 9 are symmetrically opened on one side of the top surface of the surveying instrument body 1. The grooves 9 communicate with the plug-in grooves 8; The groove 9 is in a "T" shape, the plug-in block 501 is in a "T" shape, and the bottom surface of the groove 9 does not penetrate the surveying instrument body 1; The plug-in block 501 is inserted into the plug-in groove 8, the mounting plate 502 is inserted into the groove 9, and the limiting plates 10 are symmetrically rotatably installed on the top surface of the surveying instrument body 1. The limiting plates 10 are provided with clamping holes 12; Among them, the shape designs of the groove 9 and the insertion block 501 are such that when the insertion block 501 is inserted into the groove 9, the horizontal movement of the insertion block 501 is restricted, and the groove 9 does not penetrate through the surveying instrument body 1, so that when the insertion block 501 is inserted into the groove 9, the downward movement of the insertion block 501 is restricted.

[0023] In a further embodiment, referring to Figure 1 - Figure 7 , an installation box 505 is installed on the top surface of the installation plate 502. A spring 506 is installed on the bottom surface of the inner cavity of the installation box 505. A limiting column 507 is installed on the side of the spring 506 away from the installation box 505. The outer wall of the limiting column 507 is in contact with the inner wall of the clamping hole 12; Among them, when the insertion block 501 needs to be taken out from the insertion slot 8, the limiting column 507 is pressed, and the limiting column 507 is completely pressed into the installation box 505, so that the limiting column 507 is disengaged from the clamping hole 12. Then the limiting plate 10 is rotated to release the limit on the auxiliary protection component 5, and then the insertion block 501 is taken out upward.

[0024] In a further embodiment, referring to Figure 1 - Figure 4 , sliding frames 6 are symmetrically arranged at the front end of the surveying instrument body 1. Positioning blocks 404 are slidably installed in the sliding frames 6. The two positioning blocks 404 are symmetrically distributed on both sides of the protection frame 405; Among them, the sliding frames 6 assist in limiting the moving direction of the protection frame 405.

[0025] In a further embodiment, referring to Figure 1 - Figure 4 , the protective cover 11 and the protection frame 405 slide relative to each other to improve the light-shielding property of the protection frame 405.

[0026] The working principle of the present invention is as follows: When the device is in use, after the device is set up, press the two connecting plates 402 to move closer to the middle. The two connecting plates 402 drive the two ends of the V-shaped elastic piece 407 to move closer to the middle. Subsequently, the clamping blocks 408 at the two ends of the V-shaped elastic piece 407 respectively move from the clamping grooves 7 into the interior of the installation frame 2; Subsequently, push the fixing plate 403 to drive the sliding block 401 and the protection frame 405 to move until the clamping block 408 is aligned with the next set of clamping grooves 7. Then release the pressing on the connecting plate 402. Under the elastic action of the V-shaped elastic piece 407, the clamping block 408 is clamped into the corresponding clamping groove 7 to realize the position limitation of the sliding block 401; During the movement of the sliding block 401 and the protection frame 405, the connecting rope 503 will pull the elastic ring 508, so that the elastic ring 508 is stretched, avoiding the protective net 504 from blocking the observation line of sight of the surveying instrument body 1; After use, repeat the above operations to reset the slider 401 and the protective frame 405. At this time, under the action of the elastic ring 508, the elastic ring 508 and the protective net 504 will return to their original state, and the protective net 504 covers the lens of the device, reducing the possibility of direct contact between foreign objects and the lens. The operator can safely place the device in the instrument box or other places without worrying about the lens being affected by external factors; After the device has been used for a long time, the reset performance of the V-shaped elastic piece 407, the protective net 504, and the elastic ring 508, which are elastic components, will decrease. At this time, to ensure the normal use of the device, first press the limit post 507 to completely press the limit post 507 into the installation box 505, so that the limit post 507 is disengaged from the clamping hole 12. Then rotate the limit plate 10 to release the limit on the auxiliary protection component 5, and then take out the plug-in block 501 upward; Furthermore, press the two connecting plates 402 towards the middle. The two connecting plates 402 drive the two ends of the V-shaped elastic piece 407 towards the middle. Then the clamping blocks 408 at both ends of the V-shaped elastic piece 407 respectively move from the clamping grooves 7 into the interior of the installation frame 2. And continuously press the fixing plate 403 to move the slider 401, the connecting plate 402, and the fixing plate 403 out of the installation frame 2. At the same time, slide the positioning block 404 out of the sliding frame 6 to realize the disassembly of the main protection component 4 and the auxiliary protection component 5; During installation, align the positioning block 404 on the protective frame 405 with the sliding frame 6, and make the positioning block 404 slide with the sliding frame 6. Then insert the fixing plate 403, the connecting plate 402, and the slider 401 into the installation frame 2 so that the clamping block 408 and the clamping groove 7 are directly clamped with each other; Finally, insert the plug-in block 501 into the plug-in groove 8, and make the mounting plate 502 snap into the groove 9. Then press the limit post 507 to press the limit post 507 into the installation box 505. At the same time, rotate the limit plate 10 so that the clamping hole 12 on the limit plate 10 corresponds to the limit post 507. Then under the action of the spring 506, the limit post 507 is clamped into the clamping hole 12 to realize the quick installation and disassembly of the main protection component 4 and the auxiliary protection component 5, improving the maintenance efficiency of the device.
