In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a ball inflation riveting fixed knot constructs, includes the assembly base, the top intermediate position of assembly base is provided with cylindricality riveting post, the inside of cylindricality riveting post is provided with the round hole, the top of assembly base is provided with the action part, the inside of action part and the position that corresponds the cylindricality riveting post are provided with the pilot hole, the inside of round hole is provided with pipe portion inflation ball.

Preferably, a groove is provided near the upper side of the mounting base, and the size of the area of the groove is the same as the size of the area of the action component.

Preferably, when the assembly base and the actuating member are in a connected state, an upper surface of the groove of the assembly base and an upper surface of the actuating member are flush with each other.

Preferably, the assembly base and the cylindrical riveting column are arranged in an integrated structure.

Preferably, the edge of the assembly hole is provided with a chamfer structure.

Preferably, the diameter of the cylindrical rivet column is the same as that of the assembly hole.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a processing out earlier the cylindricality of having the round hole on the assembly base rivets the post, then processing one on the action part that needs to be fixed and assembly base on the cylindricality rivet the post with the pilot hole of diameter, and do the chamfer at the edge of pilot hole, only need during the assembly with the pilot hole of action part embolia the cylindricality of assembly base on riveting the post, then impress the round hole that the cylindricality riveted the post with pipe portion inflation ball and make its inflation in, thereby play the effect of rivet, traditional structure, can enough fix the very little part of structure, again elegant appearance.
