[0042] Working principle: first, the staff needs to replace the grouting pipeline 3, the cylinder 17 starts to work. The driving end of the cylinder 17 extends and retracts, and since the driving end is fixedly connected with the connecting block 16, the connecting block 16 will move. The connecting block 16 and the pull rod 15 are in a rotating connection relationship, and the movement of the connecting block 16 will pull or push the pull rod 15. The pull rod 15 is fixedly connected with the sliding plate 14, so that the sliding plate 14 slides on the slide column 13 along the axial direction of the slide column 13. The inner wall of the sliding plate 14 is rotatably connected with the connecting rod 19 through a special bearing structure, and when the sliding plate 14 slides, the connecting rod 19 will move.

[0043] The operator manually exerts force on the rotating block 6 on the rotating disc 5 to rotate the rotating disc 5, and since the rotating disc 5 is fixedly connected with the rotating shaft 4, the rotation of the rotating disc 5 drives the rotating shaft 4 to rotate in the inner wall of the grouting pipeline 3 through high-precision bearings, and the rotation of the rotating shaft 4 further drives the ball valve 7 to perform opening and closing actions, when the rotating disc 5 rotates to a specific position, the spring 9 fixed in the outer column 8 of the outer wall of the rotating disc 5 exerts a force on the stop block 10 connected with the spring 9 and the clamping ball 11 on the stop block 10 to play a role.
