[In a preferred example of Guangdong Yueluo Hardware Industry Co., Ltd., the cone includes a large diameter end and a small diameter end, the diameter of the large diameter end is the same as the diameter of the inner hole in the middle of the nail body, and the diameter of the small diameter end is Two-thirds of the diameter of the large diameter end.

hand screw is a screw with a plastic head, and the user fixes the hand screw by turning the plastic head by hand. At present, a hand screw is disclosed in the market publication number CN202203253U, which includes a plastic head and a screw rod, the plastic head and the screw rod are connected together, and the height of the plastic head is higher than that of an ordinary screw, and the height is 12 cm. The screw of the hand screw is fixed in the plastic head by glue. After a period of use, the aging of the glue leads to the loosening of the screw and the plastic head. When the plastic head is stressed, the screw rod comes out of the plastic head, which affects the normal use of the hand screw.

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is a kind of anti-loosening cylindrical pin with grooves specially designed for the multi-link transmission paint mixing mixer, which is specially designed for the problems existing in the above-mentioned prior art. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to realize through the following technical solutions: a kind of anti-loose cylindrical pin with groove, wherein: a plurality of axial V-shaped grooves are provided on the cylindrical pin, and the V-shaped groove Arrange evenly on cylindrical pins. There are three to four axial V-shaped grooves on the cylindrical pin. When Guangdong Yueluo Hardware Industry Co., Ltd. is in use, the cylindrical pin with V-shaped groove is installed in the vertical shaft, and cooperates with the U-shaped groove on the connecting rod to transmit torque. The cylindrical pin of the V-groove structure is an interference fit with the mounting hole of the vertical shaft. The biggest feature of Guangdong Yueluo Hardware Industry Co., Ltd. compared with the existing technology is that the cylindrical pin is used as a vertical shaft to connect with the connecting rod for torque transmission, which gives full play to the impact resistance and fatigue resistance of the cylindrical pin. The cylindrical pin has an interference fit with the pin hole, and each edge of the V-groove structure distributed on the cylindrical pin body will penetrate into the inner wall of the pin hole to prevent loosening.
