[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a handheld printer thermal sheet installation structure, including an outer shell, the outer side of the outer shell is rotatably connected to an upper cover, the inner side of the outer shell is provided with an inner body, the outer side of the inner body is fixedly connected to a metal fixing frame, the interior of the metal fixing frame is provided with an empty groove, the thermal sheet body is installed inside the inner body and the empty groove, the outer side of the metal fixing frame is fixedly connected to a shielding frame, and the shielding frame is fixedly installed inside the outer shell.
[0006] Preferably, the interior of the upper cover is rotatably connected to a glue stick, the exterior of the outer shell is rotatably connected to a movable rod, two corresponding slots are provided inside the movable rod, the glue stick and the slots cooperate with each other, the interior of the outer shell is slidably connected to a card block, the exterior of the outer shell is rotatably connected to an opening button, the opening button cooperates with the movable rod and the card block, and the upper cover is conveniently opened and closed through the mutual cooperation of the upper cover, the glue stick, the opening button, the card block, the movable rod and the slot, and the opening and closing of the upper cover is facilitated by arranging a torsion spring at the rotation position of the opening button to limit it, thereby ensuring its normal operation.
[0007] Preferably, the outer shell is made of plastic material.
[0008] Preferably, a battery module is provided inside the outer shell.
[0009] Preferably, a plurality of control buttons are provided inside the outer shell.
[0010] The utility model provides a thermal sheet installation structure for a handheld printer, which has the following beneficial effects:
[0011] 1. The handheld printer thermal sheet installation structure can adapt to most standard specifications of thermal sheets through the mutual cooperation of the inner body, metal fixing frame and empty slot. The shielding frame set on the outside of the metal fixing frame can protect the metal fixing frame and fix it inside the outer shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the figure: 1. Outer shell; 3. Upper cover; 4. Rubber stick; 5. Open cover button; 6. Clamp block; 7. Movable rod; 8. Clamp slot; 9. Inner body; 10. Thermal film body; 11. Metal fixing frame; 12. Empty slot; 13. Shielding frame. DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0018] See also Figures 1 to 4 The present invention provides a technical solution: a handheld printer thermal film installation structure, comprising an outer shell 1, the outer side of the outer shell 1 is rotatably connected to an upper cover 3, an inner body 9 is provided inside the outer shell 1, a metal fixing frame 11 is fixedly connected to the outer side of the inner body 9, an empty slot 12 is provided inside the metal fixing frame 11, a thermal film body 10 is installed inside the inner body 9 and the empty slot 12, and the thermal film body 10 can be exposed from the fixing frame 11 through 12; a shielding frame 13 is fixedly connected to the outer side of the metal fixing frame 11, 13 is used to protect the thermal film body 10, and also has an aesthetic effect. The shielding frame 13 is fixedly installed inside the outer shell 1;
[0019] The upper cover 3 is internally connected to a glue stick 4 for rotation, and the outer side of the outer shell 1 is connected to a movable rod 7 for rotation. Two corresponding slots 8 are provided inside the movable rod 7, and the glue stick 4 cooperates with the slots 8. The outer shell 1 is internally connected to a card block 6 for sliding, and the outer side of the outer shell 1 is connected to a cover opening button 5 for rotation. The cover opening button 5 cooperates with the movable rod 7 and the card block 6. The cooperation between the upper cover 3, the glue stick 4, the cover opening button 5, the card block 6, the movable rod 7 and the slots 8 facilitates the opening and closing of the upper cover 3. The cover opening button 5 is limited by a torsion spring at its rotation position to ensure its normal operation, unlike other designs that place it on the side. The 7 will be placed between the thermal film body 10 and the glue roller 4 at 8. This ensures that under the same appearance, a larger standard part 10 is used, and it can be directly replaced with a customized part 10.
[0020] A battery module is disposed inside the outer shell 1 , and a plurality of control buttons are disposed inside the outer shell 1 .
[0021] To sum up, when in use, the handheld printer thermal sheet installation structure can adapt to thermal sheet bodies 10 of various specifications through the mutual cooperation of the inner body 9, the metal fixing frame 11 and the empty slot 12, thereby improving the practicality of the handheld printer thermal sheet installation structure. The shielding frame 13 set on the outside of the metal fixing frame 11 can protect the metal fixing frame 11 and fix it to the inside of the outer shell 1 at the same time.
[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
