[0024] As Figs. 1-2As shown, the embodiment designs a rivet limiting shock top iron structure, which comprises a top iron body 1, a shock absorbing sleeve 3, a shock absorbing spring 8 and other components.

[0025] The top iron body 1 is cylindrical; the top iron body 1 is generally a solid iron product, and the front end face of the top iron body 1 is in abutment with one end of the rivet during use. When the other end of the rivet is processed using a pneumatic rivet gun, the impact force generated will be transmitted to the top iron body 1 along the rivet.

[0026] The shock absorbing sleeve 3 is sleeved on the outside of the top iron body 1, the front side of the shock absorbing sleeve 3 has an opening, the rear end of the top iron body 1 extends into the shock absorbing sleeve 3, and the front end of the top iron body 1 extends out of the shock absorbing sleeve 3. The top iron body 1 can slide in the front-rear direction of the shock absorbing sleeve 3.

[0027] The shock absorbing spring 8 is arranged in the shock absorbing sleeve 3, and the rear end of the top iron body 1 abuts against the shock absorbing sleeve 3 through the shock absorbing spring 8, so as to utilize the shock absorbing spring 8 for shock absorption. This can effectively alleviate the transmission of impact force to the worker during rivet installation, achieve impact force buffering, and reduce the risk of pain, fatigue and occupational diseases to the worker.

[0028] A limiting nut 2 is sleeved on the outside of the front end of the top iron body 1, the limiting nut 2 can be threadedly connected with the top iron body 1, and the front end face of the limiting nut 2 is flush with the front end face of the top iron body 1. Thus, when the front end face of the top iron body 1 is clamped against the rivet, the front end face of the limiting nut 2 is also close to the rivet.

[0029] A plurality of soft limiting support feet 5 are arranged on the front end face of the limiting nut 2, and the number of the limiting support feet 5 can be three, as shown. Fig. 2 The limiting support feet 5 can be annularly distributed, and the limiting support feet 5 can be made of rubber material. When the top iron body 1 clamps the rivet, the limiting support feet 5 are compressed and deformed to be flush with the front end face of the top iron body 1. Through the limiting support feet 5, the friction force on the rivet is increased, the probability of displacement between the rivet and the end face of the top iron body 1 is reduced, the stability of the top iron body 1 supporting the rivet is improved, the axis of the top iron body 1 is not easy to be inclined after being aligned with the axis of the rivet, and the rivet head forming quality is improved.

The nut of the anti-falling screw 4 is arranged in the long groove, so as to prevent the top iron body 1 from being detached from the front end of the shock absorbing sleeve 3.

[0031] As the preferred structure of the above-mentioned embodiment, further: the damping guide rod 7 is fixedly arranged at the center of the rear end of the top iron body 1, and the damping spring 8 is sleeved outside the damping guide rod 7, the damping guide rod 7 can guide the extension and contraction of the damping spring 8, so as to prevent the damping spring 8 from being deflected during the extension and contraction process, the gap between the end of the damping guide rod 7 and the rear end of the damping sleeve 3 is smaller than the gap between the limiting nut 2 and the damping sleeve 3, and also smaller than the length of the anti-falling groove. The damping guide rod 7 can be inserted and matched with the top iron body 1, and the thread at the front end of the damping guide rod 7 can be threadedly connected with the threaded hole at the rear end of the top iron body 1.

[0032] The rear end of the damping sleeve 3 is semispherical, and the rear end of the damping spring 8 abuts against the inner spherical surface of the semispherical shape.

[0033] As the preferred structure of the above-mentioned embodiment, further: the outer wall of the rear end of the damping sleeve 3 is connected with the handle 6; the handle 6 can be welded and fixed with the damping sleeve 3; the handle 6 is perpendicular to the axial direction of the damping sleeve 3, and the handle 6 can be held by the operator, so as to improve the convenience of use.
