[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] A new type of portable printer, such as Figures 1 to 3 As shown, it includes a main body 1, on which a paper bin cover 2 is rotatably connected, a rubber roller 3 is arranged on the paper bin cover 2, and the rubber roller 3 is extended along the width direction of the main body 1, the rubber roller 3 is close to the movable end of the paper bin cover 2, and a shaft sleeve 4 is arranged at the end of the rubber roller 3, and the shaft sleeve 4 is sleeved on the rotating shaft of the rubber roller 3. A driving bracket 5 is arranged in the main body 1, and a clamping assembly 6 is arranged on the driving bracket 5. When the paper bin cover 2 is closed, the clamping assembly 6 fixes the shaft sleeve 4, thereby realizing the clamping fixation of the paper bin cover 2.

[0024] The clamping assembly 6 includes a limit platform 601 arranged at the end of the driving bracket 5, and elastic arms 602 are arranged on both sides of the limit platform 601. There is a gap between the two sides of the limit platform 601 and the elastic arms 602. The gap makes the elastic arms 602 more flexible and can be deformed at a larger angle. The bottom of the elastic arm 602 and the limit platform 601 are integrally formed on the driving bracket 5. The distance above the two elastic arms 602 is smaller than the diameter of the sleeve 4. When the paper bin cover 2 is closed, the sleeve 4 pushes the elastic arms 602 on both sides of the limit platform 601 outward and abuts against the limit platform 601. The elastic arms 602 abut against the sleeve 4 under the action of elastic force, thereby clamping and fixing the sleeve 4, and then fixing the paper bin cover 2 in a closed state.

[0025] A guide surface 603 is arranged on the top of the elastic arm 602 near the rotating shaft of the paper bin cover 2, and the guide surface 603 is arranged at an angle. When the paper bin cover 2 rotates, the outer elastic arm 602 will block the rotating trajectory of the shaft sleeve 4 and may be easily stuck. Therefore, a guide surface 603 is arranged on the top of the outer elastic arm 602. When the paper bin cover 2 is closed, a certain external force is used to press downward, and the shaft head can be squeezed into between the elastic arms 602 along the guide surface 603. Similarly, when the paper bin cover 2 is opened, the shaft sleeve 4 will also slide out along the guide surface 603.

[0026] A driving motor 8 is installed at the bottom of the driving bracket 5, and a driving gear is set on the output shaft of the driving motor 8. A driven gear 9 is coaxially fixed to the end of the rubber roller 3. When the paper bin cover 2 is closed, the driven gear 9 meshes with the driving gear to drive the rubber roller 3 to rotate.

[0027] The end of the driving bracket 5 is provided with a clearance groove 10. When the paper bin cover 2 is closed, the driven gear 9 penetrates into the clearance groove 10 to prevent the driven gear 9 from interfering with the connection between the shaft sleeve 4 and the clamping assembly 6, making the spatial layout more reasonable.

[0028] In this embodiment, shaft sleeves 4 are provided at both ends of the rubber roller 3, and clamping assemblies 6 cooperating with the shaft sleeves 4 are provided at both ends of the driving bracket 5. By providing two sets of shaft sleeves 4 and clamping assemblies 6, both ends of the rubber roller 3 are fixed at the same time, making the paper bin cover 2 more stable when clamped.

[0029] A mounting frame 11 is fixed on the paper bin cover 2, the rotating shaft of the rubber roller 3 is fixed in the mounting frame 11, the shaft sleeve 4 is in contact with the outer side of the mounting frame 11, and the shaft sleeves 4 at both ends can also limit the rubber roller 3 so that the rubber roller 3 will not deviate left and right.

[0030] like Figure 4 As shown, the paper bin cover 2 is provided with an easy-lifting portion 7, which makes it easier for the user to apply force to the paper bin cover 2 and lift it up. The easy-lifting portion 7 includes a groove 701 opened on the surface of the movable end of the paper bin cover 2, and a crossbeam 702 is provided above the groove 701. The paper bin cover 2 can be lifted by hooking the crossbeam 702 with fingers.

[0031] like Figure 5 As shown, in this embodiment, two supporting ribs 12 are symmetrically arranged at the bottom of the main body 1. The two supporting ribs 12 are close to the left and right ends of the main body 1. The main body 1 is placed on the ground through the supporting ribs 12.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
