Embodiment:

Coupling is seen accompanying drawing 1 to 5, coupling comprises the first shaft coupling body 1 and the second shaft coupling body 2, the center of the first shaft coupling body 1 and the second shaft coupling body 2 offers axis hole 3 respectively, the first shaft coupling body 1 and the second shaft coupling body 2 are suitable for being separately fixed in two rotating shafts, and the first shaft coupling body 1 and the 2 concentric settings of the second shaft coupling body, the utility model can realize that by the cooperation of the first shaft coupling body 1 and the second shaft coupling body 2 two folk prescriptions between the rotating shaft are to transmission.

Further point out, be respectively arranged with two guiding surfaces that are obliquely installed 4 on the fitting surface of the described first shaft coupling body 1 and the second shaft coupling body 2, guiding surface 4 lays respectively on the end face of annular wall body of the first shaft coupling body 1 and the second shaft coupling body 2, guiding surface 4 on the first shaft coupling body 1 joins end to end, and the guiding surface 4 on the second shaft coupling body 2 joins end to end; Wherein, the connecting part of the most significant end of the least significant end of a guiding surface 4 and adjacent another guiding surface 4 forms a shoulder 5.Guiding surface 4 on the first shaft coupling body 1 and the first shaft coupling body 1 play the guiding role, 5 snap action of shoulder on the first shaft coupling body 1 and the first shaft coupling body 1.
