By providing the temperature measuring rod 6, the temperature measuring rod 6 can enter the inclinometer pipeline before the detection rod 4, so that the operator can understand the temperature in the inclinometer pipeline and avoid damage to the detection rod 4.

[0026] It also includes a contraction structure, which includes a cylinder 10, which is fixedly installed on one side of the inner cavity 9, and the telescopic end of the cylinder 10 is fixedly connected to one end of the double-sided toothed plate 11; the contraction structure also includes two sets of gears 12, which are respectively meshed with the top and bottom surfaces of the double-sided toothed plate 11, and the center of the gear 12 is rotatably connected to the side wall of the inner cavity 9 through a rotating shaft, and a connecting rod 13 is fixedly installed on one side of the gear 12, and a pulley 14 is rotatably installed on the top of the connecting rod 13; a limiting groove 15 is provided on the side wall of the inner cavity 9, and the two sides of the double-sided toothed plate 11 are slidably matched with the limiting groove 15, and openings for the pulley 14 to extend out are provided at the top and bottom of the inner cavity 9.
