Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A positioning pin 75 is fixedly connected to the top of the protective cover 3. A positioning sleeve 76 is sleeved on the surface of the positioning pin 75. The bottom of the positioning sleeve 76 is fixedly connected to the top of the objective lens 2.

[0023] As a technical optimization solution of the utility model, by setting a positioning mechanism 7, the angle of the rotating shaft 5 and the protective cover 3 can be positioned to prevent the protective cover 3 from automatically rotating, resulting in the protective cover 3 being unable to align with the objective lens 2, thereby improving the working efficiency of the protective cover 3.

[0024] refer to Figure 2The left side of the positioning pin 75 is fixedly connected with a guide block 8 , and the guide block 8 is located inside the positioning sleeve 76 .

[0025] As a technical optimization solution of the present invention, by providing a guide block 8, the positioning pin 75 can be guided to avoid the positioning pin 75 being difficult to insert into the positioning sleeve 76, thereby improving the insertion efficiency of the positioning pin 75.

[0026] refer to Figure 4 A reinforcement block 9 is fixedly connected to the right side of the surface of the rotating shaft 5 , and the right side of the reinforcement block 9 is fixedly connected to the left side of the mounting block 4 .

[0027] As a technical optimization solution of the utility model, by setting a reinforcement block 9, the connection between the rotating shaft 5 and the mounting block 4 can be reinforced to avoid breakage of the rotating shaft 5 and the mounting block 4 during use, to prevent the rotating shaft 5 and the mounting block 4 from failing to cooperate, and to improve the use effect of the rotating shaft 5 and the mounting block 4.

[0028] refer to Figure 3 A wear-resistant plate 10 is fixedly connected to the left side of the spring 74 , and the wear-resistant plate 10 is located on the surface of the rotating shaft 5 .

[0029] As a technical optimization solution of the utility model, by setting a wear-resistant plate 10, the spring 74 can be isolated from contact with the moving block 73, avoiding friction between the moving block 73 and the surface of the spring 74 when rotating, causing the surface of the spring 74 to be worn, thereby improving the safety of the use of the spring 74.

[0034] The working principle and use process of the utility model are as follows: when in use, when the user needs to move the level body 1 and the objective lens 2, the moving block 73 is pushed to the right, the moving block 73 compresses the spring 74, the moving block 73 drives the rotating shaft 5 to move to the right, the rotating shaft 5 drives the block 72 to move to the right, the block 72 withdraws from the interior of the square groove 71, the rotating shaft 5 loses the positioning effect, the protective cover 3 also loses the positioning effect, the protective cover 3 is rotated, the protective cover 3 drives the rotating shaft 5, the block 72 and the moving block 73 to rotate, the protective cover 3 is separated from the objective lens 2, the objective lens 2 loses the shielding protection of the protective cover 3, thereby having the advantage of convenient protection.

[0035] To sum up: the construction engineering level, through the coordinated use of the level body 1, the objective lens 2, the protective cover 3, the mounting block 4, the rotating shaft 5, the mounting sleeve 6 and the positioning mechanism 7, solves the problem that the objective lens cover is connected to the surface of the objective lens through a threaded connection.
