[0034] The left lower end of the fixed plate 9 is rotatably connected with a large gear 13, and the inside of the large gear 13 and the upper end shaft of the bevel gear assembly 20 are both provided with a ratchet assembly 17, and the outside of the ratchet assembly 17 is provided with a small gear 16, and the small gear 16 and the tooth row 14 are meshed with each other; the movable plate 12 is slidably connected to the left and right ends of the rotating column 10, and the laser displacement sensor 11 is fixed through the middle of the movable plate 12; the movement direction of the small gear 16 is unidirectional movement, and a tooth block 18 is provided at an equal angle above the inner wall of the rotating column 10, and the tooth block 18 is meshed with the large gear 13;

[0035] When the angle of the laser displacement sensor 11 needs to be adjusted, the hydraulic cylinder 15 is controlled to operate, and the hydraulic cylinder 15 moves the gear row 14 left and right. When the gear row 14 moves to the left, the gear row 14 moves to rotate the upper and lower small gears 16. The large gear 13 rotates counterclockwise through the setting of the ratchet assembly 17, and the bevel gear assembly 20 does not rotate. The rotation of the large gear 13 drives the tooth block 18 to rotate, and the rotation of the tooth block 18 drives the rotating column 10 to rotate. The rotation of the rotating column 10 causes the internally installed parts to rotate synchronously. The rotation of the rotating column 10 will cause the small gear 16 to rotate, and the setting of the ratchet assembly 17 will not affect The gear row 14 moves normally, and the angle of the laser displacement sensor 11 can be adjusted.
