The supporting shaft is respectively plugged into the through holes, and the supporting shaft can move in the through holes, so that the supporting plate 2 is movably connected to the frame 1. At the same time, the through hole can limit the moving trajectory of the supporting shaft, thereby limiting the movement of the support plate 2.

[0050] Optionally, the supporting portion 15 forms a protrusion, and a through groove is provided at the supported portion 21, and the protrusion cooperates with the through groove. The protrusion is immersed in the through groove and can move in the through groove, so that the support plate 2 is movably connected to the frame 1, and the through groove can limit the movement trajectory of the protrusion, thereby limiting the movement of the support plate 2.

[0051] Specifically, the movement structure also includes a first protrusion 22 formed by extending a portion of the edge plate of the support plate 2 toward the frame; and a limiting portion 16 disposed at the frame for limiting the swing of the first protrusion 22 .

[0052] Optionally, the limiting portion 16 is a second protrusion corresponding to the position of the first protrusion 22, and the second protrusion is located relatively above the first protrusion 22; wherein, when the support plate 2 is pressed by the elastic member 3, so that the print head 4 is pressed, the first protrusion 22 abuts against the second protrusion, so that the tail end of the support plate 2 is temporarily fixed to the frame 1, so as to improve the stability of the support plate 2 and prevent the plate body from shifting.

[0053] Optionally, the limiting portion is a frame formed on the base plate for surrounding the first protrusion; the frame corresponds to the position of the first protrusion 22 on the support plate 2, and when the print head 4 is pressed, the first protrusion 22 sinks into the accommodating groove to limit the position, thereby preventing the support plate 2 from shifting.

[0054] Specifically, the frame 14 is provided with a mounting groove 7, and a sensor assembly 8 is installed in the mounting groove 7; the sensor assembly 8 includes a substrate 81 and a sensor 82 arranged at the substrate 81; at least one rib is provided in the mounting groove, and the rib fixes the substrate in the mounting groove; the rib includes a first rib 71 and a second rib 72, and at least two first ribs 71 are arranged on opposite sides of the mounting groove 7; there is a gap 74 between the first rib 71 and at least one side inner wall of the mounting groove 7, The edge plate of the substrate 81 is clamped in the gap 74, and the second rib 72 is in contact with and supported by the substrate 81, so that the sensor component 8 is installed in the mounting groove 7.

[0056] According to an embodiment of the present utility model, on the other hand, a printer is provided, comprising a movement structure as described in any one of the above items.

[0057] Because the printer includes a movement structure, it has the same effect as the movement structure and will not be described in detail here.

[0058] Embodiment 2

[0059] Figure 6 The structure of the second embodiment of the core structure of the utility model is shown. The difference between the second embodiment and the first embodiment is that a second pit 6 is recessed at the support plate 2 , and the second end of the elastic member 3 abuts against the second pit 6 .

[0060] The specific usage of the movement structure differs from that of Example 1 in that, when the elastic member 3 is installed, the first end of the elastic member 3 sinks into the first pit 12, and the second end sinks into the second pit 6, and the elastic member 3 is compressed; during the daily printing use of the printer, the elastic member 3 is compressed or lifted up and reset many times. During the action of the elastic member 3 being compressed or reset and stretched, the first pit 12 and the second pit 6 can effectively prevent the elastic member 3 from deflecting or collapsing, and play a role in limiting and fixing the elastic member 3.

[0061] In the present embodiment, the first pit 12 and the second pit 6 are both depressions arranged on the plate body, and the first pit 12 and the second pit 6 are arranged correspondingly. The end of the elastic member 3 sinks into the pit to take effect, so that the movement structure can meet the coordinated use of elastic members 3 of various sizes. It is only necessary that the end size of the elastic member 3 is less than or equal to the inner diameter of the pit. The installation process saves time and effort, reduces the complexity of the process, and has strong applicability.

[0062] Optionally, the support plate 2 is an aluminum plate. The density of the aluminum plate is relatively low, so the weight can be reduced during use, which facilitates the pushing action of the elastic member 3. The aluminum plate has high strength, can withstand greater pressure, is not easily deformed or damaged, and has a long service life.

[0063] Optionally, a plurality of second recesses 6 are spaced apart at the support plate 2 and correspond one-to-one to the plurality of elastic members 3 , and the plurality of second recesses 6 also correspond one-to-one to the plurality of first recesses 12 , to ensure that the elastic members 3 are stably installed at the movement structure.

[0064] Embodiment 3

[0065] Fig.13 The structure of the third embodiment of the movement structure of the utility model is shown. The difference between the movement structure of the third embodiment and the first embodiment is that the edge plate body of the support plate 2 extends in the direction away from the bottom plate 11 and is bent to form a bending portion 23, and the bending portion 23 extends in the direction close to the bottom plate 11 and is bent to form the blocking portion 5; the cross-sectional shape of the bending portion 23 and the blocking portion 5 is V-shaped.

[0066] The specific use of the core structure is different from that of the first embodiment in that the elastic member 3 abuts against the blocking portion 5 or the bent portion 23; specifically, a rib is provided on the side of the bent portion 23 facing the bottom plate 11, and the elastic member 3 is pressed by the rib. The bent portion 23 is tilted upward and forms a paper-returning slope at the edge of the support plate 2, which plays a guiding role and is conducive to better buffering transition when the paper is returned. Especially for label paper, the occurrence of peeling problems is reduced under the guiding role of the bent portion 23, thereby improving the use effect.

[0067] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. Although the embodiments of the present utility model are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations are all within the scope defined by the present utility model.
