Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a flying head rivet that draws flower, includes the nail core 1 and locates the pin fin 2 of 1 upper ends of nail core, and 1 outside cover of nail core is equipped with the nail body 3, and the nail body 3 comprises last pressure disk 4, pergola 5 and lower pressure disk 6, is equipped with spacing arch 601 in the pressure disk 6 round hole down, and spacing groove 101 has been seted up to the position that is close to the upper end on the nail core 1. According to the utility model, the structure of the nail body 3 of the existing flying-head garlands rivet is improved, so that the nail body 3 is not flying, but the flower stand 5 is folded to form a disc-type structure when the nail body 3 consisting of the upper pressure plate 4, the flower stand 5 and the lower pressure plate 6 is pressed, thereby improving the contact area of riveting and improving the connection strength. The utility model has ingenious structural design, and compared with the traditional flyhead gard rivet, the utility model has high and stable connection strength.
