The technical solution starts the motor 1 to drive the rotating shaft 1 to rotate, so that the conical gear 1 drives the conical gear 3 to rotate, the conical gear 3 drives the rotating shaft 2 to rotate, the rotating shaft 2 synchronously drives the conical gear 2 and the groove wheel to rotate, and the conical gear 2 controls the rotating roller 3 to rotate, when the conical gear 3 rotates, it controls the rotating roller 1 to rotate synchronously, and the groove wheel drives the anti-skid pad to vertically pull out the grouting gun head to prevent the grouting gun head from bending when being pulled out.

[0004] However, the above technical solution relies on the cooperation of multiple bevel gears to link the operation of multiple groove wheels, and then pushes the grouting head up by the friction between the rotation of the grooves and the grouting head, so as to realize the extraction operation of the grouting head. However, the overall structure of this technical solution is relatively complicated, and the friction force is reduced due to loss when pushing the grouting head up, which will affect the stability of the technical solution in pushing the grouting head.
