[0025] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-8 A label printer, comprising: The machine casing 1 has a printer core 11 for printing inside and a paper output port 12 for paper output on one side. A paper cutting module is disposed inside the housing 1. The paper cutting module includes a paper cutting part 13 corresponding to the paper outlet 12, a drive seat 2 corresponding to the paper cutting part 13, and a cutter 3 inserted into the drive seat 2. The paper cutting part 13 is provided with a paper cutting hole 131 corresponding to the cutter 3. The drive seat 2 is provided with a locking mechanism 4 for locking the cutter 3. The number of cutters 3 is set to several, and the blades are all different. The housing 1 is provided with a mounting hole 14 for inserting the cutter 3, a paper cutting key 5 for driving the drive seat 2 to drive the cutter 3 to cut towards the paper cutting hole 131, and a cutter key 6 for driving the locking mechanism 4 to unlock or lock.

[0026] The above structure, by setting several cutter components 3, each with a different blade head, allows users to change different blade heads to cut the label paper in different ways according to their own needs. Cutting methods include cutting the paper for use as an adhesive label, making dotted cuts for users to tear off the stub, and punching cuts to insert into the binder ring as a label, etc. In addition, through the setting of locking mechanism 4 and cutter key 6, the cutter can be stably locked by locking mechanism 4 to prevent the cutter from flying out and causing accidental injury when cutting paper. The cutter key 6 can also be used to unlock locking mechanism 4 for cutter replacement, which is convenient, quick and safe.

[0027] Specifically, the plurality of cutting blades 3 are a first cutter 31, a second cutter 32, and a third cutter 33. The first cutter 31 has a first blade 311 at its tip, the second cutter 32 has a serrated blade 321 at its tip, and the third cutter 33 has a second blade 331 spaced apart and a plurality of straight blades 332 at its tip. The first cutter 31 is used to cut the label paper, the second cutter 32 is used to make dotted line cuts on the label paper, and the third cutter 33 is used to punch holes in the label paper and then cut it. Preferably, the number of straight blades 332 is set to two. In other embodiments, the number of straight blades 332 can be adjusted adaptively according to specific circumstances.

[0028] To ensure timely waste paper disposal, the drive seat 2 and the paper cutting part 13 are arranged vertically. The blade of the cutter 3 is inserted downward into the paper cutting hole 131 to cut paper. The paper cutting hole 131 is provided with several pins 7 corresponding to the straight cylindrical blade 332. The lower end of the straight cylindrical blade 332 is provided with an annular and sharp cutting part 3321, and the interior is provided with a paper guide hole 3322 with an annular inward protrusion at the lower end and an upper end connected to the outside through the mounting hole 14. With the addition of the pins 7 and the paper guide hole 3322, when the third cutter 33 is inserted downward into the paper cutting hole 131 to cut, the pins 7 are inserted into the straight cylindrical blade 332 and push the circular waste paper cut by the cutting part 3321 into the paper guide hole 3322. This allows the circular waste paper cut off by the third cutter 33 to be pushed into the paper guide hole 3322 by the insertion pin 7 each time it cuts, thus preventing the waste paper from falling into the label printer and causing the machine to jam. Furthermore, by connecting the upper end of the paper guide hole 3322 to the outside, the waste paper can be easily poured out or removed for cleaning when the waste paper accumulates to a certain extent, thus achieving timely cleaning of the waste paper.

[0029] To improve the locking strength of the locking mechanism 4, the cutter 3 includes a cutter holder 34 and a cutter head located at the lower end of the cutter holder 34.

A plurality of annularly spaced balls 44 are embedded through the side wall of the limiting sleeve 41. The plurality of balls 44 are pressed inward by the locking ring 43 and limited to be embedded in the limiting groove 341. The cutter key 6 is used to press down the locking ring 43 to disengage from the plurality of balls 44 and unlock the cutter 3. The above structure, through the arrangement of several balls 44, allows the locking ring 43 to be sleeved on the outside of the limiting sleeve 41 by the locking spring 42. The balls 44 are then pressed inward and can be firmly locked in the limiting groove 341, thereby stably limiting the displacement of the cutter 3 in three dimensions, improving the locking strength of the locking mechanism 4. Furthermore, the locking mechanism 4 can be stably unlocked by pressing down the cutter key 6 to replace the cutter 3. After inserting the new cutter 3 into the drive seat 2 and releasing the cutter key 6, the locking mechanism 4 can again lock the cutter 3 with high strength through the balls 44, improving the stability of the cutter 3 after installation, and thus improving the stability of the cutter 3 in cutting paper.

[0030] To improve the ease of assembling and disassembling the cutter component 3, the cutter button 6 is movably positioned at the bottom and used to unlock the cutter component 3 upon pressing. The mounting hole 14 is located through the middle of the cutter button 6. This structure, by placing the mounting hole 14 in the middle of the cutter button 6, exposes the upper end of the cutter component 3 within the mounting hole 14 after pressing the cutter button 6 to unlock the cutter component 3. This facilitates disassembly or assembly by the user using their fingers to grasp the upper end of the cutter component 3, greatly improving the ease of assembly and disassembly.

[0031] To improve the flatness of the cut, the bottom of the drive seat 2 is also provided with a paper pressing component 21 located between the cutter 3 and the paper outlet 12. The paper pressing component 21 is elastically set. The core is located on the side of the cutter 3 away from the paper cutting edge. The core includes a movable print head 111 and a pressure roller 112 that rolls and presses against the print head 111. The housing 1 is provided with a reset spring 15 for driving the drive seat 2 and the paper cutting key 5 to reset. The cutter key 6 is driven to reset by the locking spring 42. Specifically, the paper pressing component 21 can be made of a highly elastic material such as a rubber block or a silicone block. After the drive seat 2 is pressed down, the paper pressing component 21 presses the outer end of the label paper and the pressure roller 112 presses the inner end of the label paper, so that the cutter can stably cut the label paper and improve the flatness of the cut.

[0032] Specifically, the housing 1 includes a lower housing 16 and an upper housing 17 that is rotated and covered on the lower housing 16. A paper tray 18 and a paper outlet 12 are formed between the upper housing 17 and the lower housing 16. The paper cutting part 13 is located on the top of the lower housing 16 near the paper outlet 12. The drive seat 2 is slidably positioned on the upper housing 17 near the paper outlet 12. The lower housing 16 has a charging port 161 for charging at the bottom and a control button 162 for turning the machine on and off at the front.
