Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

Referring to fig. 1-3, the guide wheel adjusting structure in this embodiment includes a swing arm 3 and a fixing plate 1, one end of the swing arm 3 is movably connected to the fixing plate 1, and further includes a cam 2 and a cam shaft 22, the cam shaft 22 passes through the cam 2, and further includes a handle 21, the handle 21 is connected to the cam 2, and the cam 2 can rotate around the cam shaft 22 under the action of the handle 21. The surface of the cam 2 is provided with a groove 23, the groove bottom of the groove 23 is provided with a bulge 233, the bulge 233 divides the groove 23 into a first groove 231 and a second groove 232, the other end of the swing arm 3 is abutted against the groove 23, and the swing arm 3 can swing around the connecting point 33 of the swing arm 3 and the fixing plate 1 under the action of the cam 2. One end of the swing arm 3 is provided with a first roller 31, and the first roller 31 can roll along the surfaces of the first groove 231 and the second groove 232.
