The side surfaces of the six driving sheets are respectively provided with an installation plate; and the six mounting plates and the outer circular surface of the clutch inner ring are respectively provided with an extension spring, and the six extension springs pass through the six spring avoiding grooves. When the input shaft is rotating; the input shaft can drive the driving ring shell to rotate; because the inner ring of the clutch is in a static state at the moment; the driving ring shell rotates to drive the six driving sheets to swing around the corresponding circular arc surface axes; in the rotating process of the six driving pieces; gaps between the upper ends of the six driving pieces and the inner circular surface of the first mounting groove on the clutch outer ring can be increased; while the input shaft is rotating; the input shaft can drive the trigger plate to rotate; the trigger plate cannot move transversely; the V-shaped trigger groove on the first trigger rod is matched with the V-shaped trigger cambered surface on the trigger plate; therefore, the rotation of the trigger plate can enable the first trigger rod to move towards one end, close to the supporting groove on the outer ring of the clutch, of the first circular hole; the annular inclined plane on the first trigger rod is matched with the six second trigger rods; the first trigger lever moves to cause the six second trigger levers to move along the trigger slots to the side away from the input shaft; the first trigger rod moves to drive the mounting block to move; the mounting block moves to drive the driving sheet to move; the gaps between the upper ends of the six driving sheets and the inner circular surface of the first mounting groove on the outer ring of the clutch are compensated through the movement of the driving sheets; the six driving plates are in contact with the inner circular surface of the mounting groove on the clutch outer ring; at the moment, the driving ring shell drives the six driving pieces to rotate, and then the six driving pieces are compressed; meanwhile, the trigger plate continues to push the first trigger rod in the process; finally, the annular inclined plane of the first trigger rod is just contacted with a first circular hole on the clutch inner ring; meanwhile, one end of the trigger plate, which is provided with the V-shaped trigger cambered surface, is just locked with the side surface of the square groove on the first trigger rod in the rotating process; therefore, the rotation of the trigger plate drives the first trigger rod to rotate; the first trigger lever rotates to drive the inner ring of the clutch to rotate; at the moment, the rotating speed of the clutch inner ring is the same as that of the driving ring shell; therefore, the rotation of the clutch inner ring can drive the six driving plates to rotate around the axis of the clutch inner ring; the six driving plates rotate to drive the outer ring of the clutch to rotate; the lower end of the driving sheet is an arc surface; the lower ends of the six driving pieces are arranged in six third mounting grooves through the matching of pins and pin holes; when the six driving sheets are driven by the driving ring shell to rotate; the six driving pieces can prevent the driving pieces from interfering with the mounting block in the rotating process through the arc surfaces at the lower ends of the balls; the width of the square groove is smaller than the length of the trigger plate; the depth of the V-shaped trigger cambered surface on the trigger plate is less than that of the square groove. The function of the trigger plate is to ensure that the trigger plate can push the first trigger rod to move and cannot be separated from the first trigger rod when rotating in the initial state; meanwhile, when the annular inclined plane of the first trigger rod is just contacted with the first circular hole on the clutch inner ring, the trigger plate rotates to smoothly drive the first trigger rod to rotate; in the invention, the driving ring shell can firstly drive the driving sheet to rotate for a certain angle; the function of the clutch is to ensure that the inner ring of the clutch drives the driving plate to rotate; the driving sheet can smoothly drive the outer ring of the clutch to rotate; when the outer ring of the clutch rotates in the initial state; an included angle of ninety degrees is formed between the driving sheet and the tangent direction of the contact point of the driving sheet and the inner circle surface of the outer ring mounting groove of the clutch; therefore, the outer ring of the clutch can not drive the driving plate to rotate when rotating; namely, the inner ring of the clutch is not driven to rotate; and thus does not drive the clutch input shaft to rotate.

When one uses the clutch designed by the invention; when the input shaft is rotating; the input shaft can drive the driving ring shell to rotate; because the inner ring of the clutch is in a static state at the moment; the driving ring shell rotates to drive the six driving sheets to swing around the corresponding circular arc surface axes; in the rotating process of the six driving pieces; gaps between the upper ends of the six driving pieces and the inner circular surface of the first mounting groove on the clutch outer ring can be increased; while the input shaft is rotating; the input shaft can drive the trigger plate to rotate; the trigger plate cannot move transversely; the V-shaped trigger groove on the first trigger rod is matched with the V-shaped trigger cambered surface on the trigger plate; therefore, the rotation of the trigger plate can enable the first trigger rod to move towards one end, close to the supporting groove on the outer ring of the clutch, of the first circular hole; the annular inclined plane on the first trigger rod is matched with the six second trigger rods; the first trigger lever moves to cause the six second trigger levers to move along the trigger slots to the side away from the input shaft; the first trigger rod moves to drive the mounting block to move; the mounting block moves to drive the driving sheet to move; the gaps between the upper ends of the six driving sheets and the inner circular surface of the first mounting groove on the outer ring of the clutch are compensated through the movement of the driving sheets; the six driving plates are in contact with the inner circular surface of the mounting groove on the clutch outer ring; at the moment, the driving ring shell drives the six driving pieces to rotate, and then the six driving pieces are compressed; meanwhile, the trigger plate continues to push the first trigger rod in the process; finally, the annular inclined plane of the first trigger rod is just contacted with a first circular hole on the clutch inner ring; meanwhile, one end of the trigger plate, which is provided with the V-shaped trigger cambered surface, is just locked with the side surface of the square groove on the first trigger rod in the rotating process; therefore, the rotation of the trigger plate drives the first trigger rod to rotate; the first trigger lever rotates to drive the inner ring of the clutch to rotate; at the moment, the rotating speed of the clutch inner ring is the same as that of the driving ring shell; therefore, the rotation of the clutch inner ring can drive the six driving plates to rotate around the axis of the clutch inner ring; six driving plates rotate to drive the outer ring of the clutch to rotate.
