Preferably, the edge of the slider 4 has a rounded shape to facilitate the movement of the slider 4 into and out of the opening in the follower 3, thereby preventing jamming.
The control hand wheel 2 is sleeved on the tray 5 between the driving part 1 and the driven part 3 and can rotate on the tray 5. The check ring 11 is arranged between the top of the inner vertical surface of the operating hand wheel 2 and the bottom surface of the driving part 1, so that the driving part 1 can be prevented from being worn when the operating hand wheel 2 rotates. Spiral guide holes corresponding to the number of the sliding grooves are formed in the middle of the control hand wheel 2, a pin shaft 10 penetrates through the spiral guide holes and is fixed on the sliding block 4, an external thread is arranged at the upper end of the pin shaft 10 and is connected with the inner end of a long screw rod 9 through a thread, and the outer end of the long screw rod 9 is supported and connected into a control spring seat 14 on the driving part 1 through a spring 8.

The inner side wall of the spiral guide hole takes the center of the control hand wheel 2 as the center of a circle, the radius of the outer side wall is gradually reduced, and the reduction of the radius of the outer side wall is equal to the radial movement distance of the sliding block 4; in this embodiment, the radius of the outer sidewall is gradually decreased in a clockwise direction, and when the pin 10 moves along the spiral guide hole, the spiral guide hole tightly presses the pin 10, thereby dragging the slider 4 to move in a radial direction. The inner side wall of the spiral guide hole can be provided with a thickened part to increase the contact surface with the pin shaft 10, so that the stress of the pin shaft 10 is more uniform.
The positioning spring seat 12 is arranged on the outer side of the control hand wheel 2, the positioning pin 13 is arranged in the positioning spring seat 12 through the spring 8 and abuts against the positioning spring seat 12 through the spring 8, positioning holes are respectively formed in the positions, corresponding to the positioning pin 13, of the driving part 1 in the engaging and disengaging states of the clutch, the positioning pin 13 is ejected out of the positioning spring seat 12 through the spring 8, the positioning pin 13 is inserted into the positioning holes to fix the control hand wheel 2, and therefore misoperation caused by the fact that the control hand wheel 2 rotates along with inertia is avoided.
When the operating hand wheel 2 is rotated anticlockwise, the pin shaft 10 drives the sliding block 4 to slide inwards to the sliding groove under the action of the spiral guide hole, the clutch is disengaged, the positioning pin 13 is pushed into the positioning hole by the spring 8, and the operating hand wheel 2 is prevented from rotating along with inertia. When the control hand wheel 2 is rotated clockwise, the spiral guide hole releases pressure, the pin shaft 10 moves outwards along the spiral guide hole under the action of the spring 8 and the long screw 9 to drive the sliding block 4 to slide outwards, the sliding block 4 is embedded into the opening along with the rotation of the driving part 1 to be aligned with the opening on the driven part 3, the clutch is connected, and the spring 8 pushes the positioning pin 13 into the positioning hole to prevent the control hand wheel 2 from rotating along with inertia.
