[0012] Preferably, a fourth protective layer is provided inside the protective coating layer, and an oil-resistant coating is provided inside the fourth protective layer.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By welding a second rod body to the other end of the first rod body, and installing a fixing bolt between the first rod body and the second rod body, the second rod body designed by welding with the first rod body can effectively increase the hardness and strength of the first rod body, and is not prone to bending or breaking during use. The fixing bolt can increase the stability of the connection between the first rod body and the second rod body, thereby increasing the stability during use and optimizing the use process.

[0015] 2. A protective leather cover is provided on the periphery of the first rod body and the second rod body, and a protective coating layer is provided on the periphery of the first rod body and the second rod body. The design of the protective leather cover can increase the protective effect of the first rod body and the second rod body, so that the first rod body and the second rod body are not easy to rust and corrode and age. The anti-rust coating in the first protective layer can further increase the anti-rust effect of the first rod body and the second rod body. The corrosion-resistant coating in the second protective layer can further increase the corrosion-resistant effect of the first rod body and the second rod body. The flame-retardant coating in the third protective layer can provide the first rod body and the second rod body with flame-retardant and high-temperature resistant effects. The oil-resistant coating in the fourth protective layer can provide the first rod body and the second rod body with oil-resistant effects, thereby optimizing the use process.
