In a specific embodiment, the locking mechanism comprises a sliding groove 5 and a pin 6, the sliding rail 3 slides in the sliding groove 5, a first limiting hole 7 is formed in the sliding rail 3, a second limiting hole 8 corresponding to the first limiting hole 7 is formed in the sliding groove 5, the pin 6 penetrates through the first limiting hole 7 and the second limiting hole 8 to limit the relative position of the sliding rail 3 and the sliding groove 5, a limiting boss 9 with a diameter larger than the diameter of the first limiting hole 7 and the diameter of the second limiting hole 8 is arranged at one end of the pin 6, a threaded section 10 is arranged at the other end of the pin 6, and when the sliding rail 3 and the sliding groove 5 are locked, a nut is screwed at the end of the pin 6.
After the slide rail is adjusted in place, locking is carried out by using a pin 6, and the length of the pin is longer than the width of the slide rail so as to meet the fixing requirement; the sliding groove and the inclinometer working part shell can be formed by one-time processing so as to meet the requirement of sealing performance.
