[0011] Preferably, two groups of connection grooves are respectively opened on both sides of the installation cover, and two groups of connection blocks are respectively fixedly connected to both sides of the installation groove.

[0012] Preferably, the connecting block is movably connected to the connecting groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the thermal printer paper cutter made of ceramic material can not only prevent the blade from being worn and rusted, but also can pre-cut the printed paper to improve the cutting smoothness;

[0014] (1) The fixed knife and the movable knife of the paper cutter structure are both made of ceramic. The ceramic blade has higher strength than the traditional steel-based nickel-plated blade, which can effectively reduce the speed of blade wear to increase the service life of the blade. The ceramic blade can effectively prevent the blade from rusting and maintain the sharpness of the blade for a long time, thereby effectively preventing the blade from wearing too fast or rusting.

[0015] (2) By arranging a driving gear, a driving motor, a driving shaft, a positioning groove, a transmission structure, a limiting plate, a fixing plate, a positioning shaft and a positioning hole, when cutting, the driving motor is first started to drive the driving gear to rotate through the driving shaft. While the driving gear rotates, the driving knife is driven to rise and fall continuously through the transmission structure. During the lifting and lowering of the movable knife, the printed paper can be pre-cut to improve the flatness during subsequent cutting. At the same time, the limiting plate inside the mounting groove is attached to one end of the movable knife to effectively limit the movable knife, thereby improving the stability of the movable knife when it is lifted and lowered, thereby realizing automatic pre-cutting of the printed paper.
