The short section 6 for measuring the inclination and the circuit board 7 are prior art and will not be described in detail here. A sliding cavity 10 is opened on the outer wall of the short section 1 on the left and right sides of the closed cover plate 3, and an arc-shaped connecting plate 11 is vertically inserted into the sliding cavity 10, an arc-shaped baffle 2 is fixed on the arc-shaped connecting plate 11 outside the short section 1, a spring 9 is fixed on one side of the arc-shaped connecting plate 11 in the sliding cavity 10, and one side of the spring 9 is fixedly connected to the inner wall end of the sliding cavity 10 away from the arc-shaped connecting plate 11, and the arc-shaped connecting plate 11 forms a reset structure through the spring 9. The side-view width of the arc-shaped connecting plate 11 is smaller than the side-view width of the arc-shaped baffle plate 2, and the side-view cross-section of the sliding cavity 10 is smaller than the side-view cross-section width of the arc-shaped baffle plate 2. When the arc-shaped baffle plate 2 is loosened, the arc-shaped baffle plate 2 moves toward the middle of the closed cover plate 3 through the arc-shaped connecting plate 11 under the action of the spring 9, so that the left and right sides of the closed cover plate 3 are shielded by the arc-shaped baffle plate 2, and the short segment 1 and the closed cover plate 3 can be fixed, and the arc-shaped baffle plate 2 plays a role in sealing the sliding cavity 10, preventing the sliding cavity 10 from being exposed, and the spring 9 is easily damaged by the entry of external objects.

[0022] See also Figure 3-5, the two sides of the cavity 4 close to the outer wall of the short section 1 are arranged in the shape of step grooves 14, and the bottom of the closed cover plate 3 is arranged in the shape of a step area 12 at the position corresponding to the step groove 14. The closed cover plate 3 and the short section 1 are in step surface contact, which plays a preliminary sealing effect; a rubber sealing pad 2 13 is arranged at the position of the step area 12 at the bottom of the closed cover plate 3, and a rubber sealing pad 1 8 is integrally fixed on one side of the rubber sealing pad 2 13, and the rubber sealing pad 1 8 is tightly fitted with the inner wall of the cavity 4.
