[0010] Further, the cutter sliding clamp is slidably connected to the surface of the scale chute, the fixing nut forms a telescopic structure on the surface of the scale chute, and the fixing nut forms a sliding structure on the surface of the fixed chute. The cutter sliding clamp forms a fixing structure on the surface of the scale chute through the fixing nut.

[0011] Further, the threaded abutting rod is threadedly connected to the surface of the cutter mounting seat and forms a telescopic structure, and the cutter sliding clamp controls its position on the scale plate through the threaded abutting rod.

[0012] Further, on one side surface of the cutter sliding clamp a threaded hole is provided, the threaded connection head forms a telescopic structure through the telescopic cylinder, and the threaded connection head forms a rotatable movable connection at one end of the telescopic wall of the telescopic cylinder.

[0015] 3. Beneficial effects:

[0016] The utility model is reasonably designed. Before printing, according to the width of the printing paper, the threaded abutting rod is rotated and adjusted so that the threaded abutting rod extends from one end of the starting block, and the cutter sliding clamp and the longitudinal cutter slidingly connected to the surface of the scale plate are pushed to one side of the printing paper. At the same time, the fixing nut is rotated to fix the cutter sliding clamp on the surface of the scale chute in the scale plate. At this time, the telescopic cylinder works, and the telescopic wall of the telescopic cylinder extends, driving the threaded connection head to move to the threaded hole on one side of the cutter sliding clamp. When the threaded connection head contacts the threaded hole, the threaded connection head is rotated to fixedly connect the threaded connection head with the cutter sliding clamp. At this time, the fixing of the cutter sliding clamp on the surface of the scale chute by the fixing nut is released, so that the cutter sliding clamp forms a sliding structure on the surface of the scale plate again. The printing paper is repeatedly cut by the repeated telescoping of the telescopic cylinder, avoiding the situation that when the length of the cut paper is short, the moving stroke of the cutter is too long, resulting in power waste.
