For a long time, the extrusion molding of plastic profiled materials has been a relatively weak category in my country's plastic processing industry. Single-screw extruders are used, and the extrusion die produces profiled materials with relatively simple cross-sections at a relatively low rate. In the process of processing profiled materials, it is often necessary to use a cutting frame to realize the cutting operation of the profiled materials to ensure that the cutting quality of the profiled materials is high, the speed is fast, and the effect is good.

[0004] The inventor discovered in his daily work that in the process of using universal cutting processing, there are existing universal cutting frames such as the above-mentioned that can adjust both the vertical height and the horizontal height. During the adjustment process, since the structure used for the vertical height adjustment is four bolt columns, and since the four bolt columns need to be operated separately, when the staff performs the adjustment operation, they need to rotate the bolt columns step by step, and since the bolt columns are restricted on the four corners, the bolt columns will interfere with the adjustment of the device, causing some structures of the device to get stuck during adjustment.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
