[0002] A countersunk head rivet is a commonly used rivet. The head of the countersunk head rivet can be completely sunk into the surface of the connected material, making the connection surface flat without protrusion. The lengthened rod evacuated countersunk head rivet is a special evacuated countersunk head rivet. Its characteristic is that on the basis of the standard evacuated countersunk head rivet, the length of the nail rod is increased to meet some special usage requirements.

[0003] When using the lengthened rod evacuated countersunk head rivet to fix an object, because the nail rod is relatively long, after the riveting work on the nail rod is completed, the nail head may shift, resulting in an uneven situation at the interface of the nail rod, which has a certain impact on the fixing work of the object. Content of the Utility Model

Four sliders are fixedly connected to the side surface of the rivet body and are symmetrically distributed. The outer side of the slider is slidably connected to the inside of the first chute. An extrusion groove II is formed on the side surface of the rivet body. Through the cooperation of the slider, the groove and the first chute, the nail head can be limited, effectively preventing the nail head from shifting.

[0007] Further preferably, a threaded groove is formed on the side surface of the rivet body, and a nail head is fixedly connected to the top of the rivet body, enabling it to extrude the support block so that the support block can limit and fix the object.

[0008] Further preferably, a second chute is formed on the side surface of the nail head, and the outer side of the second chute is slidably connected to the top of the support block. A clamping groove is formed on the top of the nail head, which can guide the extrusion direction of the nail head to prevent the nail head from shifting, reducing the damage rate of the device.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:
