Therefore, the input shaft cannot drive the telescopic lantern ring to rotate in the initial zero-degree to three-degree rotation process; however, the limiting ring is arranged on the input shaft, and four limiting arc blocks on the limiting ring are matched with four limiting arc grooves on the driving ring; the input shaft can drive the driving ring to rotate; the driving ring rotates to drive the three driving shafts to rotate around the axis of the driving ring; the three driving shafts can respectively drive the three trigger blocks to rotate around the axis of the driving shaft by rotating; on one hand, the rotation of the trigger block can lead one square trigger block positioned on one side of the rotation direction of the trigger block to move along the guide groove; in the moving process of the square trigger block, the dead teeth are in frictional contact with the output disc under the action of the second spring in the initial state, and the frictional force between the dead teeth and the output disc is greater than the elastic force of the second spring; the square trigger block moves to press the second spring; when the trigger block enables the compression state of the second spring to reach the limit state in the rotating process; the rotation of the trigger block can drive the corresponding square trigger block to rotate around the axis of the driving ring; the square trigger block rotates to drive the corresponding arc-shaped shell to rotate around the axis of the driving ring; the rotation of the arc-shaped shell can drive the installation ring to rotate;

compressing a third spring during the movement of the square trigger block; finally, the dead teeth and the square trigger groove reach a balanced state under the action of friction force among the second spring, the third spring, the dead teeth and the output disc; when the installation ring rotates, the 15 driving rods are driven to rotate around the axis of the installation ring; the 15 driving rods drive the 15 driving sheets to rotate around the axis of the mounting ring; the 15 driving sheets rotate to drive the 15 swinging teeth to swing around the corresponding rotating shafts; during the swinging process of the swinging teeth; when the inclined plane of the swing tooth is parallel to the side face of the corresponding square tooth; the blocking tooth positioned on one side of the rotation direction of the trigger block just moves to the outer side of the first square groove corresponding to the output disc; under the action of the second spring; the blocking teeth can be extruded into the first square groove; when the blocking teeth are matched with the corresponding first square grooves, the second spring and the third spring are in a free telescopic state; the inclined surface of the blocking tooth is just contacted and matched with the side edge of the first square groove; when the blocking teeth are matched with the corresponding first square grooves, the second spring is in a free telescopic state and the third spring is in an ultimate stretching state; the inclined plane of the blocking tooth is completely positioned on the inner side of the first square groove; so that the dead teeth can be blocked by the first square groove; namely, the mounting ring is clamped by the output disc; namely, the swinging teeth are clamped by the mounting disc; at the moment, the trigger plate on the input shaft just contacts with the limiting block; the input shaft rotates to drive the telescopic lantern ring to rotate; the telescopic lantern ring rotates to drive the input disc to rotate; the input disc rotates to drive 15 square teeth to rotate around the axis of the input disc; the 15 square teeth rotate to drive the 15 swing teeth to rotate around the axis of the input disc; 15 swinging teeth rotate to drive the output cylinder to rotate; the output cylinder rotates to drive the output disc to rotate; the output disc rotates to drive the output shaft to rotate; namely, the input shaft can drive the output shaft to rotate; when the input shaft stops rotating; the input shaft rotates reversely for a certain angle; during rotation of the input shaft; the input shaft can drive the driving ring to rotate for a certain angle; the driving ring drives the three driving shafts to rotate around the axis of the driving ring; the three driving shafts rotate a certain angle to enable the three driving shafts to drive the three triggering blocks to restore to the original positions; at the moment, the telescopic lantern ring is restored to the original position under the action of the second scroll spring; the mounting ring can be restored to the original position under the action of the first scroll spring; in the installation ring recovery process; the installation ring can drive 15 swing teeth to restore to the principle position; meanwhile, the square trigger block is restored to the original position under the action of a third spring; when the blocking teeth are matched with the corresponding first square grooves, the second spring and the third spring are in a free telescopic state; the inclined surface of the blocking tooth is just contacted and matched with the side edge of the first square groove; therefore, the installation circular ring rotates to drive the blocking teeth to restore to the original position; when the output shaft rotates; the output shaft can drive the swinging teeth to rotate around the axis of the output shaft; the front driving force of the first scroll spring to the mounting ring is greater than the elastic force of the first spring; therefore, the swing teeth can extrude the square teeth on one hand when rotating; so that the square teeth move to one side close to the input shaft hole; the square teeth move to drive the input disc to move; the input disc moves to drive the trigger ring to move; the trigger ring moves to drive the limiting ring to move; the limiting arc block and the limiting arc groove can be separated by the movement of the limiting ring; meanwhile, the mounting ring is in a static state at the moment; therefore, the rotation of the output shaft can lead the swinging teeth to swing for a certain angle; the angle enables the swing teeth to be smoother in the process of pushing the square teeth; when the square teeth are pushed to be separated from the swing teeth; the rotation of the swinging teeth can not drive the input disc to rotate; thereby not driving the input shaft to rotate; the output shaft can drive the mounting ring to rotate through the first volute spiral spring after rotating for a certain angle; the mounting ring can drive the driving ring to rotate through the driving shaft; because the limit arc block and the limit arc groove are separated at the moment; so the driving ring can not drive the limiting ring to rotate when rotating; namely, the input shaft is not driven to rotate;

When one uses the clutch designed by the invention; when the input shaft is rotating; because two groups of limit blocks are symmetrically arranged on the inner circular surface of the telescopic lantern ring in the angle triggering mechanism, which is far away from one end of the input disc; an included angle of 6 degrees is formed between two limiting blocks in each group of limiting blocks; two trigger plates are symmetrically arranged on the outer circular surface of one end of the input shaft, which is far away from the input shaft hole; the two trigger plates are respectively matched with the two groups of limiting blocks; each trigger in the two trigger plates and the two corresponding limiting blocks form an included angle of 3 degrees. Therefore, the input shaft cannot drive the telescopic lantern ring to rotate in the initial zero-degree to three-degree rotation process; however, the limiting ring is arranged on the input shaft, and four limiting arc blocks on the limiting ring are matched with four limiting arc grooves on the driving ring; the input shaft can drive the driving ring to rotate; the driving ring rotates to drive the three driving shafts to rotate around the axis of the driving ring; the three driving shafts can respectively drive the three trigger blocks to rotate around the axis of the driving shaft by rotating; on one hand, the rotation of the trigger block can lead one square trigger block positioned on one side of the rotation direction of the trigger block to move along the guide groove; in the moving process of the square trigger block, the dead teeth are in frictional contact with the output disc under the action of the second spring in the initial state, and the frictional force between the dead teeth and the output disc is greater than the elastic force of the second spring; the square trigger block moves to press the second spring; when the trigger block enables the compression state of the second spring to reach the limit state in the rotating process; the rotation of the trigger block can drive the corresponding square trigger block to rotate around the axis of the driving ring; the square trigger block rotates to drive the corresponding arc-shaped shell to rotate around the axis of the driving ring; the rotation of the arc-shaped shell can drive the installation ring to rotate; on the other hand, the rotation of the trigger block can enable the other square trigger block in the two corresponding square trigger blocks to drive the square trigger block to move along the corresponding guide groove under the action of the extrusion force of the output disc; compressing a third spring during the movement of the square trigger block; finally, the dead teeth and the square trigger groove reach a balanced state under the action of friction force among the second spring, the third spring, the dead teeth and the output disc; when the installation ring rotates, the 15 driving rods are driven to rotate around the axis of the installation ring; the 15 driving rods drive the 15 driving sheets to rotate around the axis of the mounting ring; the 15 driving sheets rotate to drive the 15 swinging teeth to swing around the corresponding rotating shafts; during the swinging process of the swinging teeth; when the inclined plane of the swing tooth is parallel to the side face of the corresponding square tooth; the blocking tooth positioned on one side of the rotation direction of the trigger block just moves to the outer side of the first square groove corresponding to the output disc; under the action of the second spring; the blocking teeth can be extruded into the first square groove; when the blocking teeth are matched with the corresponding first square grooves, the second spring and the third spring are in a free telescopic state; the inclined surface of the blocking tooth is just contacted and matched with the side edge of the first square groove; when the blocking teeth are matched with the corresponding first square grooves, the second spring is in a free telescopic state and the third spring is in an ultimate stretching state; the inclined plane of the blocking tooth is completely positioned on the inner side of the first square groove; so that the dead teeth can be blocked by the first square groove; namely, the mounting ring is clamped by the output disc; namely, the swinging teeth are clamped by the mounting disc; at the moment, the trigger plate on the input shaft just contacts with the limiting block; the input shaft rotates to drive the telescopic lantern ring to rotate; the telescopic lantern ring rotates to drive the input disc to rotate; the input disc rotates to drive 15 square teeth to rotate around the axis of the input disc; the 15 square teeth rotate to drive the 15 swing teeth to rotate around the axis of the input disc; 15 swinging teeth rotate to drive the output cylinder to rotate; the output cylinder rotates to drive the output disc to rotate; the output disc rotates to drive the output shaft to rotate.

when the input shaft 5 stops rotating; as shown in fig. 21a, the input shaft 5 is first rotated in reverse by a certain angle; during rotation of the input shaft 5; the input shaft 5 drives the driving ring 7 to rotate for a certain angle;

the rotation of the swinging teeth 10 does not drive the input disc 20 to rotate; thereby not driving the input shaft 5 to rotate; after the output shaft 1 rotates for a certain angle, the first volute spiral spring 6 drives the mounting ring 43 to rotate; the rotation of the mounting ring 43 drives the driving ring 7 to rotate through the driving shaft 31; because the limit arc block 48 and the limit arc groove 45 are already separated at the moment; so that the driving ring 7 can not drive the limiting ring 47 to rotate; i.e. without driving the input shaft 5 to rotate; the driving thin sheet 15 can ensure that when the mounting ring 43 drives the swinging tooth 10 to swing; the mounting ring 43 does not interfere with the oscillating tooth 10.
