[0052] See also Figures 1 to 9 , is a printing device as embodiment 2 of the present invention, which adopts the structure of the side cover mechanism in embodiment 1. The printing device also includes an outer shell 30 and an inner bracket 40. The inner bracket 40 is arranged in the outer shell 30, and the head chip base plate 50 is arranged on the inner bracket 40; the rotating member 10 is arranged on the inner bracket 40 and is rotatably connected to the inner bracket 40, and the driving device 20 is arranged on the inner side wall of the outer shell 30. Specifically, the rotating member 10 can be installed on the inner bracket 40 using a rotating shaft 60. At the same time, a hole for the first protrusion 12 to pass through is provided on the inner bracket 40. After passing through, it can abut against the back of the head chip base plate 50. Most of the structures of the outer shell 30 and the inner bracket 40 in this embodiment are consistent with the existing technology. The improvement lies in the connection and cooperation with the rotating member 10 or the driving device 20.

[0053] Please refer to the following for details: Figure 9The side wall of the outer shell 30 is provided with a through hole 31 for pushing the push-pull part 222. The through hole 31 needs to meet the push-pull stroke of the push-pull part 222. At the same time, before and after the push-pull key 22 is pushed, the entire through hole 31 will be covered to ensure the sealing inside the outer shell 30.

[0054] Please refer to the following for details: Figure 9 The inner wall of the outer shell 30 is provided with a latch 32 for retaining the drive device 20. The cover plate 21 is provided with a locking step 213 for engaging with the latch 32. Two locking steps 213 are provided, arranged side by side above the cover plate 21, corresponding to the two latches 32. The latch 32 is L-shaped. The drive device 20 is locked to the inner wall of the outer shell 30 by bolts. The inner side of the outer shell 30 is provided with a locking step 33. The bolt passes through the cover plate 21 and is threadedly connected to the locking step 33. The cover plate 21 is provided with a locking hole 214 for the bolt to pass through. The locking step 33 is provided with an internally threaded hole 331 for engaging with the bolt. After the two locking steps 213 are embedded in the latch 32, the bolt passes through the locking hole 214 and is screwed into the internally threaded hole 331, achieving quick installation of the drive device 20.

[0055] The opening method of the utility model is as follows:

[0056] Push the push-pull key 22 downward, and the push-pull key 22 compresses the spring 23. At the same time, the pushing part on the top of the push-pull key 22 pulls the second protrusion 13 of the rotating part 10. The rotating part 10 rotates, and the first protrusion 12 pushes the head plate 50 (or switch plate) of the movement group outward, so that the head plate 50 is separated from the movement group, and the rubber roller group is then bounced open. Since the paper bin cover is attached to the rubber roller group, the paper bin cover is also opened.

[0057] In summary, the side cover opening mechanism of the present invention realizes the side cover opening of the printing device by changing the arrangement mode and arranging the driving device and the rotating member side by side, which has the following beneficial effects compared with the existing structure:

[0058] First, this method allows operators to quickly find the push-pull button when changing the printing paper without having to bend down to find the push-pull button on the front. The cover can be opened by sliding it from the side without any other structure blocking it.

[0059] Second, the side-operated mechanism uses a side-operated mechanism perpendicular to the desktop to open the cover. Because the desktop serves as the focal point, the downward force of the human body is used to open the cover, requiring less effort to open the paper compartment cover.

[0060] Third, the side toggle mechanism uses a push-pull key and a cover plate to interlock (i.e., fit together), then slide into the buckle of the outer shell, and finally lock one or two bolts to complete the assembly. The whole machine has a simple structure and is easy to assemble, which improves assembly efficiency.

[0061] 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.
