The female card end gets into and holds the intracavity and carry on spacingly, and the pothook just with the draw-in groove joint of female card end under the torsional spring effect hook portion, makes things convenient for the position of draw-in groove to prescribe a limit to, makes the joint more accurate convenient.

The clamping groove is an annular groove, a boss is formed at the end part of the female clamping end, the hook part is arranged at the end part of the clamping hook, a groove is arranged behind the hook part, and the groove is connected with the boss in a matched mode. The annular groove enables the female clamp end to enter the accommodating cavity at any angle, so that the hook portion can be conveniently and accurately clamped with the annular groove, and when the hook portion is clamped with the annular groove, the groove is clamped with the boss, so that the connection is more stable, and the bracelet is prevented from falling off better.

Further the outer side of the hook part is in arc transition, and the boss is in a round table shape. The boss is in a round table shape, on one hand, the boss can conveniently enter the accommodating cavity under the guiding effect, on the other hand, the boss can better push the outer side of the hook part in arc transition after entering the accommodating cavity, so that the hook rotates along the hinge end, and the hook part is automatically clamped with the clamping groove under the action of the torsion spring.

Further public card portion is streamlined, and it is established that hold the great other end of chamber end less, pothook middle part articulates in the fluting, and the pothook is the horizontality under the joint state, and the top surface of pothook keeps flat with holding the chamber surface. Because the big end of public card portion one end is little, under the joint state, pothook front end and public card portion big end hold the tie and make rear end and public card portion rear portion form the difference in height, conveniently press the pothook rear end down and make it rotate along the hinged end and separate with the draw-in groove, make things convenient for it to open.

Furthermore, the female clamping part is also in a streamline shape, and the female clamping part and the male clamping part are clamped and matched to form a spindle shape integrally. The wholeness is good, and the appearance is more pleasing to the eye.

To sum up, the utility model provides a simple structure, convenient connection and open, be difficult for the pine to take off, the pleasing to the eye bracelet connection structure of appearance.
