[0068] When the interference engagement of the paw 2 and the tooth 6 is needed, the operating lever 21 is pushed, and under the pushing action of the operating assembly on the pushing assembly, the guide rod 4 moves along the axis in the direction of approaching the chuck 1, the gradually expanding part 16 on the guide rod 4 is in contact with the driving part 13 on the paw 2 and gradually pushes the driving part 13 to make the paw 2 rotate, and the paw 2 obtains the folding movement trend; at this time, the paw 2 and the tooth 6 are uncertain in the initial state position, so there are two possibilities in the process of the paw 2 approaching the tooth 6, if the clamping part 11 of the paw 2 is just staggered with the tooth peak of the tooth 6, with the movement of the guide rod 4, the paw 2 is successfully folded and interference with the tooth 6 is formed, at this time, when the second power end input power, the tooth 6 will transmit the torque to the paw 2, the chuck 1 and the first power end. If the clamping part 11 of the paw 2 is just not staggered with the tooth peak of the tooth 6, just abuts against the tooth peak of the tooth 6, the bending part 12 of the paw 2 will form rigid contact with the tooth peak of the tooth 6 at the moment, but because the outer end of the paw 2 and the tooth peak of the tooth 6 are both gradually tapered from inside to outside, so it can be considered that at this moment, the linear contact between them and the mutual extrusion; because the second connecting part 5 is keyed connected with the second power end, and the rotary connection between the paw 2 and the chuck 1 also has a certain assembly gap, so when the outer end of the paw 2 and the tooth peak of the tooth 6 extrude each other, the paw 2 and the tooth 6 will lose stability under the driving force of the paw 2, which will promote the guide rod 4 to produce a small rotational deviation angle, under the guidance of the tapered structure of the outer end of the paw 2 and the tooth peak of the tooth 6, the outer end of the paw 2 produces the folding movement of approaching the tooth 6 and side slipping relative to the tooth 6, and then successfully forms interference with the tooth 6 after a short pause, and then realizes the transmission of torque.

[0069] When the interference engagement of the paw 2 and the tooth 6 is needed, the operating lever 21 is pushed, and under the pushing action of the operating assembly on the pushing assembly, the guide rod 4 moves along the axis in the direction of approaching the chuck 1, the gradually expanding part 16 on the guide rod 4 is in contact with the driving part 13 on the paw 2 and gradually pushes the driving part 13 to make the paw 2 rotate, and the paw 2 obtains the folding movement trend; at this time, the paw 2 and the tooth 6 are uncertain in the initial state position, so there are two possibilities in the process of the paw 2 approaching the tooth 6, if the clamping part 11 of the paw 2 is just staggered with the tooth peak of the tooth 6, with the movement of the guide rod 4, the paw 2 is successfully folded and interference with the tooth 6 is formed, at this time, when the second power end input power, the tooth 6 will transmit the torque to the paw 2, the chuck 1 and the first power end. If the clamping part 11 of the paw 2 is just not staggered with the tooth peak of the tooth 6, just abuts against the tooth peak of the tooth 6, the bending part 12 of the paw 2 will form rigid contact with the tooth peak of the tooth 6 at the moment, but because the outer end of the paw 2 and the tooth peak of the tooth 6 are both gradually tapered from inside to outside, so it can be considered that at this moment, the linear contact between them and the mutual extrusion; because the second connecting part 5 is keyed connected with the second power end, and the rotary connection between the paw 2 and the chuck 1 also has a certain assembly gap, so when the outer end of the paw 2 and the tooth peak of the tooth 6 extrude each other, the paw 2 and the tooth 6 will lose stability under the driving force of the paw 2, which will promote the guide rod 4 to produce a small rotational deviation angle, under the guidance of the tapered structure of the outer end of the paw 2 and the tooth peak of the tooth 6, the outer end of the paw 2 produces the folding movement of approaching the tooth 6 and side slipping relative to the tooth 6, and then successfully forms interference with the tooth 6 after a short pause, and then realizes the transmission of torque.
