[0021] Reference Figure 1 and Figure 2 The printer shown in the figure is easy to disassemble and assemble the cutter assembly, which includes a main body 1, a paper bin 2, a mounting plate 3, a cutter assembly 4 and a switch plate 5, wherein the paper bin 2 and the mounting plate 3 are fixedly arranged in the main body 1, and the mounting plate 3 is located on one side of the paper bin 2, a first mounting position 21 is opened at the upper end of the paper bin 2, and a second mounting position 31 is arranged on the mounting plate 3, the cutter assembly 4 can be placed in the first mounting position 21 from top to bottom, and the switch plate 5 is rotatably connected to the second mounting position 31, and the upper end of the switch plate 5 is provided with a buckle claw 51, and the lower end is provided with a A switch button 53 is provided, a buckle groove 41 is provided at the lower end of the cutter assembly 4 at a position corresponding to the buckle claw 51, and an elastic member 52 is also provided between the mounting plate 3 and the switch plate 5. The elastic member 52 acts on the switch plate 5 so that the switch plate 5 always has a tendency to rotate relative to the mounting plate 3, and the buckle claw 51 always has a tendency to move toward the cutter assembly 4 as the switch plate 5 moves. The switch button 53 passes through the lower end of the main body 1 so that a person can pull the switch button 53 by hand, thereby driving the switch plate 5 to rotate relative to the mounting plate 3.

[0022] When installing the cutter assembly 4, the cutter assembly 4 is inserted into the first installation position 21 from top to bottom, and the buckle groove 41 at its lower end passes over the buckle claw 51 so that the buckle claw 51 can buckle and fix the cutter assembly 4, and the cutter assembly 4 is connected and fixed to the paper bin 2 / main body 1; when disassembling the cutter assembly 4, a person manually pulls the switch button 53 to drive the switch plate 5 to rotate relative to the mounting plate 3, and the buckle claw 51 rotates with the switch plate 5 to disengage from the buckle groove 41, and the other hand of the person can drive the cutter assembly 4 to be removed from the paper bin 2 / main body 1 from bottom to top.

[0023] In some possible embodiments, the first installation position 21 is two vertical guide grooves formed on opposite sides of the paper bin 2, and guide blocks are correspondingly provided on opposite sides of the cutter assembly 4. During installation, the guide blocks are aligned with the vertical guide grooves so that the cutter assembly 4 is inserted into one side of the paper bin 2 from top to bottom.

[0024] In some possible embodiments, the second mounting position 31 is two rotating holes relatively arranged on the mounting plate 3, and rotating shafts 54 are arranged on opposite sides of the switch plate 5. The rotating shafts 54 can be inserted into the rotating holes, and the rotating shafts 54 are arranged in the middle of the switch plate 5. When a person manually pushes the switch button 53 to move away from the center of the main body 1, the switch plate 5 rotates relative to the mounting plate 3 and drives the claw 51 to rotate away from the buckle groove 41. After the hand is released, the elastic restoring force of the elastic member 52 can drive the switch plate 5 to rotate and reset, and the claw 51 rotates with the switch plate 5 in the direction close to the buckle groove 41 and buckles into the buckle groove 41.

[0025] In some possible embodiments, two mounting guide grooves 32 are provided on the mounting plate 3, and the mounting guide grooves 32 are arranged above the second mounting position 31. One end of the elastic member 52 is crimped to the bottom of the mounting guide groove 32, and the other end is crimped to the switch plate 5, that is, the elastic member 52 is always compressed and always applies a force to the switch plate 5, so that the buckle claw 51 has a tendency to always approach / buckle into the buckle groove 41.

[0026] In some possible embodiments, an inclined guide surface 511 is formed at the upper end of the pawl 51, the purpose of which is to force the pawl 51 / switch plate 5 to rotate when the lower end surface of the cutter assembly 4 is crimped against the pawl 51, so that the pawl 51 can pass over the lower end surface of the cutter assembly 4 and be engaged in the buckle groove 41.

[0027] In some possible embodiments, the printer of the present application also includes a base 6, and the main body 1 is fixedly mounted on the base 6. The base 6 is also provided with a through hole 61 for accommodating the switch button 53 to pass through. Furthermore, the lower end surface of the base 6 should also be provided with a supporting foot, and the height of the switch button 53 passing through the base 6 should not be higher than the supporting foot to ensure that the printer can be placed stably on a plane; further, the switch button 53 is arranged close to the edge of the main body 1 so that a person can easily push the switch button 53 by hand. Specifically, a person only needs to push the switch button 53 toward the center of the main body 1 to disengage the claw 51 from the buckle groove 41, and the elastic member 52 can drive the switch plate 5 / switch button 53 to reset.

[0028] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
