For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] An embodiment of the present utility model provides a printer that can be adapted to different cutter replacements, including a printer core 10 and two or more cutter modules; the cutter types of at least two of the cutter modules are different;

[0026] The printer core 10 is provided with a first fixing part 21;

[0027] Each of the cutter modules is provided with a second fixing part 301;

[0028] During assembly, the cutter module is detachably connected in the paper feeding direction through the first fixing part 21 and the second fixing part 301.

[0029] In specific implementation, the printer that can be adapted to different cutter replacements includes a printer core 10 and two or more cutter modules; the cutter types of at least two cutter modules are different; both the printer core 10 and the cutter module can adopt existing structures, such as an integral cutter module 31 and a split cutter module 32;

[0030] As Figure 1 shown, the printer core 10 is provided with a first fixing part 21;

[0031] As Figure 3 、 Figure 4 shown, each of the above two or more cutter modules is provided with a second fixing part 301;

[0032] As Figure 5 、 Figure 6As shown in the figure, during assembly, the cutter module is detachably connected in the paper feeding direction through the first fixing part 21 and the second fixing part 301. The detachable connection methods of the first fixing part 21 and the second fixing part 301 include but are not limited to bolt connection, snap connection, buckle connection and other structures.

[0033] During use, a printer movement 10 is equipped with two or more cutter modules. By setting the same second fixing part 301 structure on different cutter modules and detachably connecting the second fixing part 301 with the first fixing part 21, different cutter modules can be adaptively connected to the first fixing part 21 of the printer movement 10. When the user needs to replace the cutter module, the original cutter module is disassembled, and a new cutter module is replaced and installed.

[0034] The printer provided by the embodiment of the present utility model that can adapt to different cutter replacements solves the problem that the existing printers have too limited usage scenarios and cannot meet the multi-scenario usage needs of users through the structure of detachably connecting the first fixing part 21 provided on the printer movement 10 and the same second fixing part 301 provided on different cutter modules.

[0035] Further, fixing plates 20 are provided on both sides of the printer movement 10. The first fixing parts 21 are provided at the opposite positions of the two fixing plates 20.

[0036] Second fixing parts 301 are provided at the positions corresponding to the first fixing parts 21 on both sides of the cutter module. The first fixing part 21 is detachably connected to the corresponding second fixing part 301.

[0037] During specific implementation, as Figure 1 shown, fixing plates 20 are provided on both sides of the printer movement 10. The two fixing plates 20 are arranged oppositely along the printer movement 10. The first fixing parts 21 are provided at the corresponding positions of the two fixing plates 20.

[0038] Second fixing parts 301 are provided at the positions corresponding to the first fixing parts 21 on both sides of the cutter module. The first fixing part 21 is detachably connected to the corresponding second fixing part 301. By applying force to the cutter module through the two fixing plates 20, the interference and influence of the cutter module on the printer movement 10 during operation can be reduced, and the overall stability of the printer can be improved.

[0039] Further, the first fixing part 21 is a through hole, the second fixing part 301 is a threaded groove, and the threaded end of the bolt member 40 passes through the through hole and is threadedly connected to the threaded groove.

[0040] In specific implementation, the first fixing part 21 is a through hole; the second fixing part 301 is a threaded groove; the threaded end of the bolt part 40 passes through the through hole and is threadedly connected to the threaded groove. Through the connection between the bolt part 40 and the threaded groove, the detachable connection between the cutter module and the printer movement 10 is realized. The connection between the bolt and the threaded groove has a simple structure and is convenient for disassembly and installation.

[0041] Furthermore, a clamping groove 22 is also provided on the inner side wall of the fixing plate 20; one side of the clamping groove 22 is open, and the other side is recessed downward; a clamping protrusion 302 is provided at a position corresponding to the clamping groove 22 on the cutter module;

[0042] The clamping protrusion 302 is arranged in the recess through the clamping groove 22; when the clamping protrusion 302 is arranged in the recess, the first fixing part 21 corresponds to the second fixing part 301.

[0043] In specific implementation, as Figure 1 、 Figure 2 shown, the opposite sides of the two fixing plates 20 are the inner sides. A clamping groove 22 is provided on the inner side wall of the fixing plate 20; one side of the clamping groove 22 facing the paper feeding direction is open, and the other side is recessed downward; a clamping protrusion 302 is provided at a position corresponding to the clamping groove 22 on the cutter module;

[0044] During assembly, the clamping protrusion 302 enters the recess through the clamping groove 22. At this time, the first fixing part 21 also corresponds to the second fixing part 301. Through the structure in which the clamping protrusion 302, the clamping groove 22 cooperate with the first fixing part 21 and the second fixing part 301, on the one hand, the cutter module can be aligned, so that the cutter module is correctly installed on the printer movement 10; on the other hand, the stability of the cutter module after installation is improved.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
