The top of the second compression spring 14 is fixed with an extrusion plate 15, and the extrusion plate 15 is slidably connected with the support table 1, so that when the protection frame 3 is lowered in the inside of the support table 1, the bottom of the protection frame 3 can be supported by the cooperation of the extrusion plate 15 and the second compression spring 14, so that the protection frame 3 will not be lowered without external force.

[0030] Preferably, the bottom of the inside of the support table 1 and located at the side where the two positioning plates 12 are away from each other are fixed with travel blocks 24, so that when the two positioning plates 12 are away from each other, the positioning plate 12 cannot continue to move when the positioning plate 12 is contacted with the travel block 24, and the position of the limiting block 16 on the positioning plate 12 corresponds to the position of the protection frame 3 lowered in the inside of the support table 1, and when the protection frame 3 is lowered in the inside of the support table 1 and contacted with the top of the travel block 24, the lowering of the protection frame 3 in the inside of the support table 1 is the maximum depth, and the protection frame 3 will not be contacted with the top of the measuring instrument main body 2.

[0032] In the embodiment, the structures all have their own service life, and in actual manufacturing and application, different materials of corresponding structures can be replaced according to the use needs, and the rigidity of the spring and the elasticity of the pressure resistance can be selected according to the specific need of the extrusion degree in actual application.

[0033] In the embodiment, the motor is a self-locking motor, which can normally drive the connected structure to rotate when it is powered on, and when the motor stops working, it can prevent the connected structure from rotating through the self-locking function.

[0034] The use process of the angle laser measuring instrument provided by the application is as follows: in use, the protection frame 3 is installed inside the support table 1 outside the measuring instrument main body 2 through sliding, so that, when the protection frame 3 is lowered inside the support table 1, the top and both sides of the measuring instrument main body 2 are protected by the protection frame 3, preventing external stones and other objects from contacting the measuring instrument main body 2, and at the same time, when the protection frame 3 is lowered, the limiting block 16 is extruded by the contact between the second extrusion slope 20 and the first extrusion slope 17, so that the limiting block 16 drives the positioning plate 12 to move synchronously after being extruded, at this time, the two positioning plates 12 move close and drive the first compression spring 13 to compress, when the limiting block 16 corresponds to the position of the first rectangular groove 21 on the protection frame 3, at this time, the limiting block 16 is not extruded by external force, and after rebounding by the compression of the first compression spring 13, the limiting block 16 enters the inside of the first rectangular groove 21, so that the protection frame 3 cannot be directly pulled upward to separate from the support table 1, and at the same time, the lowering of the protection frame 3 drives the second compression spring 14 to compress through the extrusion plate 15, and then the bottom of the protection frame 3 is supported by the rigidity of the second compression spring 14, so as to realize the protection of the top and both sides of the measuring instrument main body 2 by the protection frame 3. When the protection frame 3 needs to be separated from the support table 1, the protection frame 3 can be extruded downward again, so that, when the protection frame 3 is lowered and contacts the adjusting plate 18 supported by the supported block 19 through the second extrusion slope 20, at this time, the lowering of the protection frame 3 extrudes the adjusting plate 18 again, so that the positioning plate 12 drives the first compression spring 13 to compress and move again, and at the same time, when the lowering of the protection frame 3 makes the adjusting plate 18 reset through the rebound of the first compression spring 13, the adjusting plate 18 enters the inside of the first rectangular groove 21, so that, when the protection frame 3 moves upward, the adjusting plate 18 rotates inside the positioning plate 12, and at the same time, after the upward rotation of the adjusting plate 18, the adjusting plate 18 is supported by the limiting block 16, and then, through the inclination of the adjusting plate 18, the protection frame 3 rises and extrudes the adjusting plate 18 through the contact, so that the protection frame 3 moves upward and separates from the support table 1. When the measuring instrument is in use, the lens of the measuring instrument main body 2 is irradiated by external sunlight, the displacement driving motor 10 can be driven to work to drive the first gear 11 to rotate, the rotation of the first gear 11 drives the second gear 23 connected through meshing to rotate, the rotation of the threaded rod 9 drives the displacement plate 8 connected through threads to move, the translation of the displacement plate 8 inside the fixed shell 4 drives the sunshade 5 to move synchronously, so that the sunshade 5 extends from the top of the protection frame 3 and is located at the top of the lens of the measuring instrument main body 2, and then the sunshade 5 shields the lens of the measuring instrument main body 2 from sunlight.
