As shown in figures 1-3, the quick-replaceable hand riveter head comprises a connecting piece 1, wherein one end of the connecting piece is inserted with a gun head 2, the other end of the connecting piece 1 is connected with a fixing head 3 in a threaded manner, and the fixing head 3 is inserted with the gun head 2 and coaxially arranged.

Specifically, fixed head 3 is used for being connected with the hand riveter, and connecting piece 1 is used for fixed rifle head 2 and fixed head 3, and rifle head 2 is pegged graft in connecting piece 1 and is withstood through fixed head 3 to rifle head 2, fixed head 3 and connecting piece 1 can synchronous rotation, and rifle head 2 can regularly be changed, prevents the fracture.

In a preferred embodiment, the gun head 2 is a bolt, the top of the gun head 2 is provided with a limiting block 21, and the limiting block 21 is provided with a polygonal groove 22.

The gun head 2 is a common bolt, the cost is low, the gun head 2 can be effectively prevented from being broken in a product only by regular replacement, and the limiting block 21 and the gun head 2 are integrally formed.

Further, the lower surface of the fixing head 3 is provided with external threads, and a polygonal protrusion 31 matched with the polygonal groove 22 is formed at the bottom of the fixing head 3.

When in use, the convex blocks 31 are inserted into the grooves 22, so that the fixed head 3 and the gun head 2 are tightly connected.

The connecting piece 1 is a hexagonal nut with two open ends, the inner surface of one end opening of the connecting piece 1 is provided with an inner thread matched with the outer thread, a flange 11 is formed at the opening of the other end of the connecting piece 1, the diameter of the opening of the flange 11 is smaller than that of the limiting block 21, and the gun head 2 penetrates through the flange opening and is limited in the connecting piece 1 through the limiting block 21.

Specifically, the flange 11 cooperates with the limiting block 21 to limit the gun head 2 in the connecting piece 1, and the gun head 2 is fixed by inserting the lug 31 of the fixing head 3, so that the gun head 2, the fixing head 3 and the connecting piece 1 integrally rotate, and the outer diameter of the limiting block 21 is attached to the inner diameter of the connecting piece 1, so that the gun head 2 is prevented from shaking.
