In the third direction Z, the distance between the two protrusions 38 is less than the length of the sliding shaft 315, and the length of the sliding shaft 315 is less than the distance between the two grooves 37. The protrusions 38 block the sliding shaft 315 in the moving direction of the sliding shaft 315, preventing the sliding shaft 315 from moving further and leaving the groove 37. The distance between the two protrusions 38 is less than the length of the sliding shaft 315 and less than the distance between the two grooves 37, which can make the sliding shaft 315 normally slide in the groove 37, and the sliding shaft 315 will not move out of the groove 37, improving the stability of the cooperation and the reliability of the structure. The length of the sliding shaft 315 is the length of the sliding shaft 315 in the axial direction. The side wall of the groove 37 near the shaft 322 is provided with a flat portion 371 corresponding to the positions of the first positioning groove 3212 and the second positioning groove 3213.

The first positioning groove 3212 and the second positioning groove 3213 are limit structures of the sliding shaft 315. When the sliding shaft 315 is arranged in the first positioning groove 3212 or the second positioning groove 3213, the sliding shaft 315 will not continue to move in the sliding groove 3211, which can prevent the distance between the sliding shaft 315 and the stop portion 314 from changing, affect the on-off state of the flush pipe 5, and increase the reliability and stability of the structure. When the flush pipe 5 is in a closed state, the first gap 316 is less than or equal to the sum of the thicknesses of the two layers of the flush pipe 5. When the flush pipe 5 is in an open state, the first gap 316 is greater than the sum of the thicknesses of the two layers of the flush pipe 5.

When the sliding shaft 315 is located in the second positioning groove 3213, the first gap 316 is greater than the sum of the thicknesses of the two layers of the flush pipe 5. At this time, it is in an open state. It is convenient to operate and the structure is reliable.

[0059] The first positioning groove 3212 and the second positioning groove 3213 are arc-shaped grooves, the radius of the arc-shaped groove is greater than the radius of the sliding shaft 315 and less than the diameter of the sliding shaft 315. It not only ensures the smooth movement of the sliding shaft 315 into the arc-shaped groove, but also does not need to move in the radial direction of the rotating shaft 322 when the sliding shaft 315 moves into the sliding groove 3211. Only by rotating the rotating shaft 322, the movement of the sliding shaft 315 in the sliding groove 3211 and the smooth entry and exit of the first positioning groove 3212 and the second positioning groove 3213 can be realized. The rotating portion 321 is fan-shaped, and the angle of rotation of the rotating shaft 322 and the sliding shaft 315 is less than or equal to 90 degrees. In this way, the on-off of the flush pipe 5 can be realized by a smaller stroke.
