[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present utility model provides a technical solution: a POS printer with a detachable cover body, including a POS printer body 1, an operation panel 101 and a wiring hole 102;

[0023] An operation panel 101 is installed inside the POS printer main body 1. A wiring hole 102 is provided on one side of the POS printer main body 1. An operation button 103 is installed on the side of the POS printer main body 1 where the wiring hole 102 is provided. A paper cassette bin body 2 is provided inside the POS printer main body 1. A thermal printing component 401 is installed inside the paper cassette bin body 2. A thermal paper body 201 is placed inside the paper cassette bin body 2. A flip cover body 3 is installed on one side of the POS printer main body 1. A transmission component 4 is connected to the bottom of the flip cover body 3. An outer flip cover 5 is provided on the outside of the flip cover body 3;

[0024] A docking post 501 and a limiting ring 502 are installed at the bottom of the outer flip cover 5. A clamping post 503 and a plugging post 504 are installed inside the flip cover body 3. The size of the plugging post 504 matches the size of the docking post 501. The clamping post 503 is inserted into the inside of the limiting ring 502. A guiding layer 505 is provided on one side of the flip cover body 3, and a limiting groove 506 is provided on the side of the flip cover body 3 close to the guiding layer 505. A limiting block 507 is connected to the bottom of the outer flip cover 5. The limiting block 507 is engaged with the limiting groove 506.

[0025] During specific implementation, to improve product production efficiency and reduce production costs, an outer flip cover 5 is provided on the outside of the flip cover body 3. When installing, first insert and limit the docking post 501 at the bottom of the outer flip cover 5 with the plugging post 504 on the upper side of the flip cover body 3. After limiting, continue to press the outer flip cover 5 downward. At this time, the limiting ring 502 at the bottom of the outer flip cover 5 will be squeezed by the clamping post 503 to deform to both sides until the limiting ring 502 is inserted with the clamping post 503, and the rotational installation of the outer flip cover 5 can be completed. At the same time, after the side of the outer flip cover 5 away from the limiting ring 502 is squeezed along the guiding layer 505 by the limiting block 507, it will be inserted and limited with the limiting groove 506 on one side of the flip cover body 3, and the position of the outer flip cover 5 can be limited to avoid shaking during use. For this POS printer with a detachable cover body, an outer flip cover 5 that is convenient for disassembly and assembly is provided on the outside of the flip cover body 3. When replacing, just remove the outer flip cover 5 and replace it, which reduces production costs and improves replacement efficiency.

A positioning groove 601 is provided inside the positioning frame 6. The two sides of the positioning frame 6 are connected to a connecting block 603 through an elastic wristband 602. A first suction block 604 is installed inside the connecting block 603. A second suction block 605 is installed inside the inner side of the positioning frame 6. The first suction block 604 and the second suction block 605 are arranged with opposite magnetic poles.

[0027] In specific implementation, to prevent the POS printer from falling due to hand slippage during use and hitting the ground and being damaged, a positioning frame 6 is installed at the bottom of the POS printer body 1, and elastic wristbands 602 are connected to both sides of the positioning frame 6. When using the POS printer body 1, the POS printer body 1 is sleeved with the user's forearm through the elastic wristbands 602 to limit the POS printer body 1, effectively preventing the POS printer body 1 from falling. When the POS printer body 1 needs to be stored after use, the elastic wristbands 602 are folded, the connecting block 603 is rotated, and the connecting block 603 is inserted into the positioning slot 601. At this time, the second suction block 605 inside the positioning slot 601 will attract the first suction block 604 at the connecting block 603 to limit the connecting block 603. This POS printer with a detachable cover is provided with elastic wristbands 602 and a connecting block 603 that can be stored and used, effectively preventing the POS printer body 1 from falling off during use and being convenient for storage after use.

[0028] In summary, when using this POS printer with a detachable cover, first press the operation button 103 to open the POS printer body 1, then dock it with the wiring hole 102 through a data cable to conduct the information to be printed to the operation panel 101 of the POS printer body 1 for display, and control the conveying component 4 to convey the thermal paper body 201 inside the paper cassette bin body 2 through the operation panel 101, and print the information on the thermal paper body 201 through the thermal printing component 401.
