[0024] The lifting drive assembly 1 can drive the paper pressing frame 2 to move up and down, and the paper pressing assembly can cooperate with the paper support assembly to press the paper tightly.

[0025] By means of the structural coordination of the anti-slip groove 201 and the anti-slip protrusion 301 , the paper can be further compressed effectively, thereby preventing the cutter assembly from sliding during the paper cutting process.

[0026] An anti-skid layer is provided on the anti-skid groove 201 and the anti-skid protrusion 301 , and the anti-skid effect can be further improved by providing the anti-skid layer.

[0027] The anti-skid grooves 201 are arranged through both ends of the pressing portion, and the anti-skid protrusions 301 are also arranged through both ends of the paper supporting portion.

[0028] The through-going setting can be used to perform anti-slip treatment on the entire end of the paper to ensure a smooth cutting surface.

[0029] The cross-sectional shape of the paper supporting portion is W-shaped, and the stability of the anti-slip effect can be effectively improved through the W-shaped setting.

[0030] Obviously, the anti-skid groove 201 is provided on the lower pressing part, the paper supporting part is provided on the paper supporting part, and the anti-skid protrusion 301 cooperating with the anti-skid groove 201 is provided on the paper supporting part to achieve an anti-skid effect. The number of the anti-skid groove 201 and the anti-skid protrusion 301 can also be, for example, two, three, four, etc., which can also achieve the effect of the above solution.

[0031] The paper support assembly includes a lifting compression spring 4 and a paper support 3 arranged above the lifting compression spring 4. There are two groups of paper support assemblies and two groups of pressing parts. The two groups of pressing parts cooperate with the two groups of paper supports 3 respectively, and the cutter assembly is arranged between the two groups of paper support assemblies.

[0032] The two sets of paper support assemblies can effectively assist a single cutter to cut paper stably and prevent shaking or deviation at the left and right ends of the paper.

[0033] The cutter assembly comprises a cutter mounting frame 6 and a paper cutter 5. The cutter mounting frame 6 is provided with a mounting position matched with the paper support assembly, and the mounting position is provided with a clearance groove matched with the paper support frame 3 for lifting and lowering movement.
