Specifically, a limiting block (not shown) extending along an axial direction is disposed on an outer peripheral wall of the connection sleeve 210, a limiting groove (not shown) extending along an axial direction is disposed on an inner wall of the rotation sleeve 220, and the limiting block of the connection sleeve 210 can move along an axial direction in the limiting groove of the rotation sleeve 220, so that the connection sleeve 210 and the rotation sleeve 220 can only move relatively along the axial direction and cannot rotate relatively along the circumferential direction. The gear 230 is fixedly sleeved on the outer wall of the rotating sleeve 220, the gear 230 on the rotating sleeve 220 is meshed with the rack in the closed track 110, when the moving rod 240 drives the rotating disc 200 to move along the closed track 110, the gear 230 on the rotating sleeve 220 is meshed with the first rack 111, the rotating sleeve 220 rotates, and the moving rod 240 can only move in the closed track 110 and does not rotate, so that the rotating sleeve 220 drives the connecting sleeve 210 to rotate and further drives the rotating disc 200 to rotate.
Specifically, the moving rod 240 is in screw fit with the connecting sleeve 210, specifically, a threaded groove is formed in the inner wall of the connecting sleeve 210, and threads are formed on the outer peripheral wall of the moving rod 240, and the moving rod 240 and the connecting sleeve are connected through the threads.

That is, the connection sleeve 210 rotates to drive the rotating disc 200 to rotate, and at the same time, the connection sleeve 210 drives the rotating disc 200 to move along the axial direction of the rotating disc 200.
For example, when the moving rod 240 rotates clockwise along the closed track 110, the gear 230 on the rotating sleeve 220 is meshed with the rack, and the rotating sleeve 220 drives the connecting sleeve 210 to rotate counterclockwise and drives the connecting sleeve 210 to move upwards along the axial direction thereof, so as to drive the rotating disc 200 to rotate counterclockwise and lift.
In a further embodiment, the gears 230 on the front sides of the adjacent two rotating sleeves 220 in the moving direction are engaged with the racks first, and the other gear 230 is engaged with the racks later. Specifically, there is a space between every two adjacent racks, that is, there is a space between the first rack 111 and the second rack 112, between the second rack 112 and the third rack 113, and between the third rack 113 and the fourth rack 114. Taking the example that the rotating discs 200 rotate clockwise along the closed track 110 and taking the intervals between the first rack 111 and the second rack 112 and the intervals between the second rack 112 and the third rack 113 as the example, one of the two rotating discs 200 is positioned in the interval between the first rack 111 and the second rack 112, the other is positioned in the interval between the second rack 112 and the third rack 113, the two rotating discs 200 synchronously move in the closed track 110, and the rotating disc 200 positioned in the interval between the second rack 112 and the third rack 113 is meshed with the third rack 113 firstly, namely rotates and rises firstly; the rotating disk 200 located in the interval between the first rack 111 and the second rack 112 is then engaged with the second rack 112, i.e., is rotated up.
Specifically, in this embodiment, 8 rotating discs 200 are disposed in the closed track 110 at intervals, as shown in fig. 3, for example, 8 rotating discs 200 move synchronously in the closed track 110, and the gear 230 on the rotating sleeve 220 of each two adjacent rotating discs 200 is meshed with the rack in a sequence, that is, in the moving direction, the gear 230 on the rotating sleeve 220 of one rotating disc 200 located at the front side of the two adjacent rotating discs 200 is meshed with the rack first, that is, the rotating disc 200 is lifted up by rotation first, the rotating disc 200 is lifted up by rotation second, and meanwhile, the rotating disc 200 is lifted up by rotation first, the rotating disc 200 located at the front side is lifted up by rotation second, and then the valve end cover 400 on the two adjacent rotating discs 200 is prevented from rubbing against the contact surface.
For example, when the first rotary table 200 moves clockwise in the closed orbit 110, the gear 230 on the rotary sleeve 220 of the first rotary table 200 is engaged with the first rack 111, the first rotary table 200 rotates counterclockwise while the height increases, the second rotary table 200 moves synchronously with the first rotary table 200 after the first rotary table 200 moves to the interval between the first rack 111 and the second rack 112, the gear 230 on the rotary sleeve 220 of the first rotary table 200 is disengaged from the interval between the first rack 111 and the second rack 112 to engage with the second rack 112, and then the gear 230 on the rotary sleeve 220 of the second rotary table 200 is engaged with the first rack 111. Meanwhile, the gear 230 on the rotating sleeve 220 of the first rotating disc 200 is separated from the second rack 112, that is, the first rotating disc 200 stops rising first, then, the gear 230 on the rotating sleeve 220 of the second rotating disc 200 is separated from the first rack 111, rising is stopped later, at this time, the valve end cover 400 on the second rotating disc 200 rises until abutting the valve end cover 400 on the first rotating disc 200, and then, the first rotating disc 200 rises first, and the second rotating disc 200 rises later, so that friction is avoided.

In a further embodiment, the closed track 110 may be circular, or may be other shapes, for example, in this embodiment, the closed track 110 is formed by two straight sections and an arc section, where an included angle of the two straight sections is 90 ° as shown in fig. 7, and the other ends of the two straight sections are connected by the arc section to form a closed track. The first rack 111 and the second rack 112 are located in a straight section on the left side of the closed track 110, the third rack 113 and the fourth rack 114 are located in a straight section on the right side of the closed track 110, and the first rack 111, the second rack 112, the third rack 113 and the fourth rack 114 are all outside the closed track 110. An arc-shaped rack 115 is arranged in the arc section of the closed track 110, the arc-shaped rack 115 is arranged on the inner side of the closed track 110, the shape of the arc-shaped rack 115 is matched with that of the arc section, and teeth of the arc-shaped rack 115 face the closed track 110. The rotating disk 200 moves in opposite directions in the two straight sections of the closed track 110 and moves in the circular arc end. For example, when the rotating disk 200 moves in the straight section and rotates counterclockwise, the rotating disk 200 rotates clockwise when moving in the arc section, and at the same time, when the rotating disk 200 moves in the straight section, the rotating disk 200 can rotate counterclockwise and rise, and when moving in the arc section, the rotating disk 200 can rotate clockwise and drop.
