BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

A lock clutch device comprising a knob 1 , a first turntable 2 , a return spring 3 , a second turntable 4 , a push plate 5 , an execution component 6. Spring 7, rotation shaft 8, and rotation ring 9; the first turntable 2 is fastened to the knob 1; the return spring 3 is set inside the second turntable 4, and the first turntable 2 is set on the second turntable 4 The outside, the first turntable 2, the return spring 3, and the second turntable 4 are rotatable about the same central axis; the push plate 5 has a slot 51, the first antenna 31 on the return spring 3, and the second antenna 32 In the slot 51 of the push plate 5, when the return spring 3 is rotated by the external force, the first antenna 31 and the second antenna 32 push the push plate 5 to move left and right; the shaft 8 has a hole 81 and the actuator 6 , the spring 7 is sequentially assembled in the hole 81 of the rotating shaft 8; the push plate 5 is opposite to the actuator 6; the rotating ring 9 is mounted on the rotating shaft 8, and the two can rotate around the same central axis;

As shown in Fig. 1 and Fig. 2, the knob 1 rotates clockwise when subjected to an external force, thereby driving the first turntable 2 Rotating clockwise together, as the first turntable 2 rotates, the rib 21 of the first turntable 2 applies a circumferential force to the first antenna 31 of the return spring 3, forcing the return spring 3 to rotate clockwise, thereby driving the push plate 5 Move to the right, push the plate 5 and push the actuator 6 to move to the right in the guide hole 81 of the rotary shaft 8, and execute the execution pin 61 of the assembly 6 to the spring during the right shift. Compression is generated, and as the actuator 6 moves, the hole 81 of the execution pin 61 projecting from the rotary shaft 8 is inserted into the groove 91 of the rotary ring 9, thereby forming the rotary shaft 8 and the rotary ring 9 Connection, at this time, the clutch device is in an engaged state, and can be interlocked with each other;

As shown in Fig. 3 and Fig. 4, when the knob 1 is rotated counterclockwise by an external force, the first turntable 2 is driven. Rotating counterclockwise together, as the first turntable 2 rotates counterclockwise, the rib 22 of the first turntable 2 applies a circumferential force to the second antenna 32 of the return spring 3, forcing the return spring 3 Rotate counterclockwise to move the push plate 5 to the left, cancel the thrust of the push plate 5 on the actuator 6. The actuator 6 moves to the left under the spring force of the spring 7 to reset the pin 61. The rear end exits the groove 91 of the rotary ring 9 and retracts into the hole 81 of the rotary shaft 8, thereby forming a separation of the rotary shaft 8 and the rotary ring 9, and the clutch device is in a separated state;

In summary, the clutch is controlled by the clockwise and counterclockwise rotation of the knob to control the connection and disengagement of the clutch.
