[0009] Further preferably, the connecting column, the pressure-bearing seat and the connecting cover are an integrated structure.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In the utility model, the coaxiality between the roller body and the through hole can maintain the uniform force applied to the guide roller at all locations during use, thereby avoiding the guide roller from breaking during the force application process. The anti-slip groove can increase the friction coefficient of the outer surface of the roller body, so that the guide roller has a stable transmission capacity during use and avoids slipping.

[0012] In the utility model, the positioning slot can be used to maintain the synchronous rotation operation between the connecting cover and the roller body during use, wherein the connection method between the roller body and the connecting cover is relatively simple and convenient to operate, and the connection method can also use rollers of different sizes, which is convenient for replacing and adjusting different guide rollers. The connecting covers on the left and right sides can support the roller body, and the connecting column, the pressure-bearing seat and the connecting cover are integrally cast and have higher pressure-bearing capacity. The cross-section of the end of the connecting column adopts a polygonal structure, which is convenient for the disassembly and adjustment of the guide roller as a whole.
