The disadvantage of this fastening method is that the efficiency of fastening adjacent components is low, and it needs to be rotated multiple times to fasten
On the other hand, the plane on the adjacent side of the nut and the thread is at a fixed angle of 90° or 135° to the length direction of the screw. When the screw length direction is not 90°, the fastening effect of these two fasteners will be greatly reduced

The invention discloses an impact type fastening combining and connecting bolt. The included angle between the top end plane of a bolt sleeve of the combining and connecting bolt and the length direction of the combining and connecting bolt is within the range of 15-165 degrees, and the included angle between the top end plane of a bolt body of the combining and connecting bolt and the length direction of the combining and connecting bolt is within the range of 15-165 degrees. The fastening force between the bolt sleeve and the bolt body is from a parallel barb structure on the inner surface of the bolt sleeve and the outer surface of the bolt body. The combining and connecting bolt can be fastened in a butt joint mode through mechanical head-on collision and has the advantages of being efficient, convenient and high in strength.
Description
technical field [0001] The invention relates to an impact-type fastening assembly nail, in particular to an assembly nail suitable for fastening adjacent components with irregular surfaces. Background technique [0002] At present, there are generally metal screw and nut combinations or plastic screw and nut combinations as fasteners on the market. The fastening methods of these two types of fasteners are all completed by the nut rotating clockwise or counterclockwise on the thread of the screw. The disadvantage of this fastening method is that the efficiency of fastening adjacent components is low, and multiple rotations are required to fasten. On the other hand, the plane on the adjacent side of the nut and the thread is at a fixed angle of 90° or 135° to the length direction of the screw. When the length direction of the screw is not 90°, the fastening effect of these two fasteners will be greatly reduced. Contents of the invention [0003] The object of the present ...
