[0023] A push rod 6 is provided at a position on the outer surface of the level ruler body 1 corresponding to the first clamping block 405, and one end of the push rod 6 is inserted into the inner wall of the level ruler body 1 and slidably connected to the inner wall of the level ruler body 1, and limiting circular blocks are welded and fixed at both ends of the push rod 6. When the baffle 401 needs to be disassembled, the push rod 6 is pressed to push the first clamping block 405 out of the inner wall of the level ruler body 1, so that the baffle 401 and the level ruler body 1 are separated from each other, and then the limiting circular block is used to limit the push rod 6 to prevent the push rod 6 from detaching from the inner wall of the level ruler body 1.

[0024] The inner wall connected to the level ruler body 1 is provided with a horizontal device 5, and the horizontal device 5 includes a leveler 501. A second spring 502 is fixedly connected to the inner wall of the connection between the leveler 501 and the level ruler body 1. One end of the second spring 502 is fixedly connected to the inner wall of the leveler 501, and the other end is welded and fixed with a second clamping block 503 which is slidably connected to the inner wall of the leveler 501.

During the movement of the clamping plate 302, the reset spring 304 is squeezed, so that the elastic potential energy of the reset spring 304 increases. The elastic potential energy of the reset spring 304 is used to clamp the clamping plate 302 and the installation groove 301 together, so as to achieve the purpose of fixing and straightening the two sections of the level ruler body 1. The baffle plate 401 is installed in the connecting groove opened on the outer wall of the level ruler body 1, so that the inner wall of the connecting groove squeezes the first clamping block 405, and the first clamping block 405 is forced to shrink and enter the baffle plate 4 01, and at the same time, the first spring 404 is squeezed to increase the elastic potential energy of the first spring 404. When the position of the first clamping block 405 moves to correspond to the clamping slot opened on the inner wall of the connecting groove, the elastic potential energy of the first spring 404 is used to push the first clamping block 405 into the clamping slot to achieve fixed installation of the baffle 401, and the rotating rod 402 is rotated to drive the reflecting mirror 403 to adjust the angle. After the angle of the reflecting mirror 403 is adjusted to a suitable position, the reflecting mirror 403 is used to observe the level 501 to straighten the level ruler body 1.
