[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution adopted by the utility model is as follows: a displacement sensor proposed by the utility model includes a displacement sensor body 1, a mounting seat 2, an adjustment cavity 3 and an adjustment component 4, the adjustment cavity 3 is rotatably arranged in the mounting seat 2, the adjustment component 4 is arranged in the adjustment cavity 3, the upper end of the adjustment component 4 extends to the top of the adjustment cavity 3, the displacement sensor body 1 is installed on the adjustment component 4, a rotating shaft 11 is provided in the middle of the lower bottom wall of the adjustment cavity 3, a rotating seat 12 is provided on the mounting seat 2, the adjusting cavity 3 is rotatably arranged in the mounting seat 2 through the cooperation of the rotating shaft 11 and the rotating seat 12, an annular limit gear ring 13 is provided in the mounting seat 2, elastic cards 14 are symmetrically provided at both ends of the rotating shaft 11, the elastic cards 14 are engaged and connected with the annular limit gear ring 13, and a plurality of fixed brackets 15 are provided on the mounting seat 2.

[0019] like Figure 3 and Figure 2 As shown, the adjustment component 4 includes an adjustment handle 5, an adjustment shaft 6 and a sensor fixing frame 7. The adjustment shaft 6 is rotatably arranged between the two inner walls of the adjustment cavity 3, and the adjustment handle 5 is rotatably arranged on one side of the adjustment cavity 3. One end of the adjustment shaft 6 handle extends into the adjustment cavity 3 and is arranged opposite to the middle of the adjustment shaft 6.
