[0002] A rivet is a nail-shaped object used to connect two parts with a through hole and a cap at one end. In riveting, interference fit is used to connect the riveted parts. There are many types of rivets, and they are not restricted by form. Brushed rivets are one of them.

[0003] Some existing brushed rivets may have low riveting strength after riveting due to insufficient strength of the supporting tube. Some existing brushed rivets may also cause rebound due to metal stress during riveting, which may cause the rivet to slip during riveting. Therefore, a brushed rivet with an anti-slip structure is urgently needed to solve the above problems. Summary of the invention

[0011] As a preferred technical solution of the present invention, the upper and lower surfaces of the inner connecting column are matched with the notch to provide an arc-shaped support block, the width of the arc-shaped support block matches the width of the notch and one end of the arc-shaped support block is horizontally rectangular and is attached to the outer surface of the connecting tube, and a first push rod is provided between the two arc-shaped support blocks and the stop block.

[0012] As a preferred technical solution of the present invention, a friction layer is provided on the outer surfaces of the arc-shaped support block and the micro-block.

[0013] As a preferred technical solution of the present invention, the arc-shaped support block and the micro-card block are made of soft and elastic materials.
