A project not only includes the construction process, but also covers all the preliminary preparations. In the early preparations of the project, various measuring equipment is needed to plan the construction site. Therefore, a measuring equipment that is easy to fix the project cost is used to measure the project site.

[0003] Prior art includes a utility model with publication number CN214889875U, which discloses a measurement device for engineering cost that is easy to fix.

[0024] In this embodiment: the fixing device 6 is arranged inside the connecting seat 1, and the fixing device 6 includes a positioning column 61 and a connecting groove 62. The connecting groove 62 is opened on the surface of the connecting seat 1, the positioning column 61 is fixedly connected to the lower surface of the base 3, the positioning column 61 is clamped with the inner wall of the connecting groove 62, and a clamping groove 63 is opened on the surface of the positioning column 61. A positioning block 64 is fixedly connected to the side of the positioning column 61, and the positioning block 64 is clamped with the inner wall of the connecting groove 62.

[0025] Specifically, a pull hole 65 is formed inside the connection groove 62 , and a clamping plate 66 is slidably connected to the inner wall of the pull hole 65 .

[0026] In this embodiment, by providing a clamping plate 66, the positioning column 61 can be restricted, thereby reducing the possibility that the device is easily separated from the inside of the connecting base 1 when in use, causing the measuring device 4 to shake.

[0027] Specifically, the clamping plate 66 is clamped with the inside of the clamping slot 63 , a concave hole 68 is opened on the surface of the clamping plate 66 , and the clamping slot 63 is provided to facilitate the connection between the clamping plate 66 and the positioning column 61 .

[0028] Specifically, a first spring 67 is fixedly connected to the inner wall of the recessed hole 68 , and one end of the first spring 67 away from the recessed hole 68 is fixedly connected to the inside of the pulling hole 65 . The first spring 67 is provided to facilitate applying a restoring elastic force to the clamping plate 66 .

[0029] In this embodiment: a protective device 7 is provided on the surface of the measuring instrument 4, and the protective device 7 includes a connecting column 71 and a protective cover 72. The connecting column 71 is fixedly connected to the surface of the measuring instrument 4, and the protective cover 72 is provided on the surface of the lens 5. One end of the protective cover 72 is fixedly connected to a rotating rod 74, and a rotating groove 73 is provided on the surface of the connecting column 71. A limiting groove 75 is provided at one end of the rotating groove 73. The rotating rod 74 is rotatably connected to the inner wall of the rotating groove 73, and a limiting block 76 is fixedly connected to the side of the rotating rod 74, and the limiting block 76 is clamped with the inner wall of the limiting groove 75.

[0030] In this embodiment, the protective cover 72 is provided to protect the lens 5, thereby reducing the risk of dust being easily absorbed by the surface of the lens 5 when the device is in use, thereby reducing the risk of the lens 5 being blocked and unable to be used.

[0031] Specifically, one end of the rotating rod 74 is fixedly connected to the second spring 78 , and one end of the second spring 78 away from the rotating rod 74 is fixedly connected to the rotating block 77 . The second spring 78 is provided to facilitate applying a restoring elastic force to the rotating rod 74 .

[0032] Specifically, the rotating block 77 is rotatably connected to the inner wall of the rotating groove 73 , and the rotating block 77 is provided to facilitate the rotation of the second spring 78 .

[0033] Working principle: When the equipment is in use, the user opens the bracket 2, then places the bracket 2 on the ground, and then connects the base 3 at the lower end of the measuring device 4 with the connecting seat 1 to firmly connect the measuring device 4. When the equipment is in use, the user pulls the card plate 66. When the card plate 66 moves, it drives the first spring 67 to displace and deform to generate elastic force, and then the card plate 66 moves out of the inside of the card slot 63, and then the positioning column 61 loses its restraint. Pulling the positioning column 61 drives the positioning block 64 to move out of the inside of the connecting slot 62, and then the positioning column 61 loses its restraint and escapes from the inside of the connecting slot 62. By setting the fixing device 6, the measuring device 4 is effectively fixed, which plays a role in facilitating and quickly fixing the measuring device 4, reducing the situation that when the equipment is in use, the measuring device 4 and the connecting seat 1 are generally firmly connected by bolts. The use of bolts requires tools to operate, and the use of tools is too cumbersome, which makes it difficult to quickly fix the measuring device 4, thereby improving the practicality of the equipment.

[0034] When the device is in use, the user pulls the protective cover 72 to move. When the protective cover 72 moves, it drives the rotating rod 74 to move. When the rotating rod 74 moves, it drives the limiting block 76 to move out of the limiting groove 75. Then the rotating rod 74 drives the second spring 78 to displace and deform to generate elastic force. Then the rotating rod 74 rotates and drives the brick to rotate. Then the rotating rod 74 drives the protective cover 72 to separate from the surface of the lens 5. By setting up the protective device 7, the surface of the lens 5 is effectively protected, which plays a role in protecting the surface of the lens 5. When the device is in use, the lens 5 is easily adsorbed with dust, the surface of the lens 5 is blocked, and the lens 5 is difficult to observe. The practicability of the device is improved.
