Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; it may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model in specific circumstances.

[0017] The utility model provides a highly stable split cutter printer, comprising a printer body 10 and an upper cover 20; the printer body 10 is provided with a movable cutter 11; the upper cover 20 above the movable cutter 11 is provided with a fixed cutter 21;

[0018] The printer body 10 is provided with a movable blade 12 for the movable blade 11 to move; a first positioning groove 13 and a second positioning groove 14 are sequentially provided along the length direction on one side of the movable blade 12; and the upper cover 20 is provided with an elongated positioning post 22;

[0019] When the upper cover 20 is assembled with the printer body 10 , the positioning posts 22 are engaged with the first positioning grooves 13 and the second positioning grooves 14 .

[0020] When implementing it specifically, Figure 1 As shown, a highly stable split cutter printer includes a printer body 10 and an upper cover 20; the printer body 10 is provided with a movable cutter 11; the upper cover 20 above the movable cutter 11 is provided with a fixed cutter 21; the printer body 10 adopts an existing printer mechanism; the structures of the movable cutter 11 and the fixed cutter 21 and the cutting principle thereof are all prior art and will not be described in detail here;

[0021] The printer body 10 is provided with an elongated movable blade 12 for the movable blade 11 to move; a first positioning groove 13 and a second positioning groove 14 are sequentially provided along the length direction on one side of the movable blade 12; and an elongated positioning post 22 is provided on the upper cover 20.

[0022] When the upper cover 20 is assembled with the printer body 10 , the positioning posts 22 are engaged with the first positioning grooves 13 and the second positioning grooves 14 .

[0023] The highly stable split cutter printer provided by the embodiment of the present utility model adds an elongated positioning post 22 around the fixed knife 21 of the upper cover 20, and adds a first positioning groove 13 and a second positioning groove 14 that are mutually compatible with the positioning post 22 around the movable knife 11 of the printer body 10. When the upper cover 20 and the printer body 10 are assembled, the positioning of the split knife is achieved through the engagement and positioning of the positioning post 22 with the first positioning groove 13 and the second positioning groove 14, thereby reducing the cumulative assembly error of the split knife and improving the paper cutting stability of the split knife.

[0024] Furthermore, the opening ends of the first positioning groove 13 and the second positioning groove 14 are both chamfered.

[0025] When implementing it specifically, Figure 1 As shown, the positioning post 23 is cylindrical; the upper ends of the first and second positioning grooves 13, 14 are open, with chamfers on both sides. By increasing the diameter of the upper ends of the positioning grooves by chamfering, the engagement time between the positioning post 22 and the first and second positioning grooves 13, 14 can be shortened, thereby improving assembly efficiency.

[0026] Furthermore, the upper cover 20 is connected to the printer body 10 via a rotating shaft 23;

[0027] The length direction of the rotating shaft 23 is perpendicular to the length direction of the positioning column 22 .

[0028] When implementing it specifically, Figure 1 As shown, the upper cover 20 is connected to the printer body 10 via a shaft 23; the length of the shaft 23 is perpendicular to the length of the positioning post 22. Due to the structural arrangement of the shaft 23 and the positioning post 22, when the upper cover 20 and the printer body 10 are assembled, the end of the positioning post 22 closest to the shaft 23 can first enter the first positioning groove 13. As the positioning post 22 continues to move toward the printer body 10, it is restrained by the first positioning groove 13 for a second time, further reducing assembly errors of the split blade.

[0029] Furthermore, the first positioning groove 13 and the second positioning groove 14 are respectively provided at two ends of the movable blade 12 .

[0030] In a specific implementation, the first positioning groove 13 and the second positioning groove 14 are respectively provided at both ends of the movable blade 12. By providing the first positioning groove 13 and the second positioning groove 14 at both ends of the movable blade 12 in the length direction, the interference or influence on the cutter during paper cutting can be reduced.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
