Then, the lower bracket 006 is set on the lower cover 005 to achieve convenient installation.

[0037] Please refer to the following for details: Figure 2 、 3The driving assembly 10 includes an opening button 11 arranged on the outside of the lower cover 005, and a button fixing block 12 arranged on the inside of the lower cover 005 and connected to the opening button 11; the outer wall of the lower cover 005 is provided with a sliding groove 051 for the sliding of the opening button 11, and the bottom of the sliding groove 051 is provided with a sliding hole 052 connected to the inside of the opening cover; the opening button 11 is embedded in the sliding groove 051, and the end passes through the sliding hole 052 and is connected to the button fixing block 12 located inside the lower cover 005; when installing the driving assembly 10, first place the button fixing block 12 inside the lower cover 005, place the opening button 11 in the sliding groove 051, and the end passes through the sliding hole 052 and is connected to the button fixing block 12.

[0038] Please refer to the following for details: Figure 3 The cover opening button 11 includes a pressing portion 111 embedded in the sliding groove 051, a mounting portion 113 that can pass through the sliding hole 052 and is connected to the button fixing block 12, and a connecting shaft portion 112 for connecting the pressing portion 111 and the mounting portion 113; the outer wall of the connecting portion of the mounting portion 113 and the button fixing block 12 is further provided with a limiting step 1131 for limiting the rotation of the pressing portion 111, and the end of the mounting portion 113 away from the pressing portion 111 is further provided with a locking step 1132, the inner side of the button fixing block 12 is provided with a mounting hole 121 for cooperating with the mounting portion 113, and the inner side of the mounting hole 121 is further provided with a limiting groove 122 for cooperating with the limiting step 1131, and the mounting The inner diameter of hole 121 is larger than the outer diameter of mounting portion 113, and the outer diameter of locking step 1132 is larger than the inner diameter of mounting hole 121. Since both cover opening button 11 and button fixing block 12 are made of plastic, under the action of external force, locking step 1132 can pass through mounting hole 121 and become locked. Locking step 1132 and mounting hole 121 are both provided with guiding inclined surfaces for easy installation, so as to facilitate installation of mounting portion 113 into mounting hole 121. In this embodiment, there are two limiting steps 1131, which are symmetrically arranged on the outer wall of mounting portion 113.

In this embodiment, bolts can also be used to install cover opening button 11 and button fixing block 12 on lower cover 005.

[0039] Please refer to the following for details: Figure 4The cover opening assembly 20 includes two hooks 21 rotatably connected to the lower bracket 006 and corresponding to the two groups of drive assemblies 10, and a connecting rod 22 for connecting the two hooks 21; non-cylindrical connecting columns 221 are provided at both ends of the connecting rod 22, and connecting holes 2121 for cooperating with the connecting columns 221 are provided on the hook 21; specifically, an avoidance hole 062 for the hook 21 to pass through is provided on the lower cover 005. During installation, the connecting holes 2121 of the two hooks 21 are first installed on the connecting columns 221 at both ends of the connecting rod 22, and then the hook 21 is passed through the avoidance hole 062, and then the two rotating shafts 23 are used to pass through the hook 21 respectively to realize the rotational connection between the hook 21 and the lower bracket 006.

[0040] Please refer to the following for details: Figure 4 , wherein the hook 21 includes a rotating part 211 rotatably connected to the lower bracket 006, a driven part 212 arranged below the rotating part 211, and a hook part 213 arranged above the rotating part 211, wherein the rotating shaft 23 passes through the rotating part 211 to rotatably connect the hook 21 to the lower bracket 006; the connecting hole 2121 is arranged on the driven part 212 and away from the side of the driving component 10, and the lower corner of the driven part 212 close to the driving component 10 is provided with a rounded corner or an inclined angle for easy installation.

[0041] Please refer to the following for details: Figure 4 The torsion spring 30 has an elastic portion 31 and a first elastic arm 32 and a second elastic arm 33 connected to the elastic portion 31, wherein the first elastic arm 32 rests on the lower bracket 006, and the second elastic arm 33 rests on the cover opening assembly 20; the side wall of the rotating portion 211 is provided with a supporting step 2111 for hooking the second elastic arm 33, and the lower bracket 006 is provided with a cylindrical protrusion 061 for the elastic portion 31 to be sleeved. During installation, the elastic portion 31 is first sleeved on the cylindrical protrusion 061. Since the hook 21 is rotatable, when installing the torsion spring 30, the hook 21 is rotated so that the angle between the bottom of the hook 21 and the side of the lower bracket 006 where the elastic portion 31 is installed becomes larger, so that the first elastic arm 32 and the second elastic arm 33 can be installed in place very quickly and without much effort. After installation, the first elastic arm 32 rests on the lower bracket 006, and the second elastic arm 33 rests on the driven portion 212.

[0042] After the torsion spring 30 and the cover opening assembly 20 in this embodiment are installed to the lower bracket 006, and the two sets of drive assemblies 10 are installed to the lower cover 005, the lower bracket 006 with the torsion spring 30 and the cover opening assembly 20 is placed in the lower cover 005 with the drive assembly 10. Since the driven part 212 is provided with a rounded corner or an inclined angle, during the downward movement of the lower bracket 006, since the bracket and other components have their own weight, only a slight downward pressure is needed, and the cover opening assembly 20 can push open the driven part 212, realizing convenient and quick installation. After the lower bracket 006 is placed in place, it only needs to be locked with a number of bolts. Example

[0043] See also Figures 1 to 7 , which is a printer as embodiment 2 of the present invention, includes the cover-opening structure of embodiment 1. The printer also includes an upper cover 001 and an upper bracket 002 disposed within the upper cover 001 and pivotally connected to the lower bracket 006. The upper cover 001 and lower cover 005 are closed together, and a paper inlet 007, a paper roll compartment 008, and a paper feed path 009 are located between the upper bracket 002 and the lower bracket 006. The paper inlet 007 is located at one end of the pivotal connection between the upper bracket 002 and the lower bracket 006. Both the paper inlet 007 and the paper feed path 009 are connected to the paper roll compartment 008. The paper roll compartment 008 provided in this embodiment is suitable for printing with paper rolls, and the paper inlet 007 is suitable for printing with a single flat sheet of paper (i.e., a single sheet or strip of paper), overcoming the traditional single paper feed method and improving the practicality of the printer.

[0044] After the hook portion 213 passes through the upper bracket 002, it hooks the upper bracket 002 to prevent the upper bracket 002 from opening. The two cover opening buttons 11 are pushed forward, and the driven portion 212 is pushed. The hook portion 213 of the hook 21 moves backward and disengages from the upper bracket 002. At this time, the upper cover 001 can automatically pop open under the action of the thermal head.

[0045] To sum up, the cover opening structure of the present invention modularizes the existing multiple parts by setting a driving component, a cover opening component and a torsion spring, wherein the driving component is installed on the lower cover, and the cover opening component and the torsion spring are installed on the lower bracket of the seat. Then, the lower bracket is set on the lower cover to achieve convenient installation.

[0046] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
