[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0030] like Figure 1 As shown, it is a schematic diagram of a keypad structure based on marking and grading in a preferred embodiment of the utility model. A keypad based on marking and grading in this embodiment includes a knob keyboard 100 and a numeric keyboard 101 arranged relatively to each other. The upper end of the knob keyboard 100 is provided with a first knob 102 and a second knob 103 that can be rotated and pressed. The first knob 102 and the second knob 103 can respectively realize different functions by rotating and pressing. In this embodiment, the numeric keyboard 101 is used to input scores. When the first knob 102 is rotated, page zooming can be realized. Pressing determines the input score. When the second knob 103 is rotated, the page can be moved left and right. When pressed, the score is cleared. The knob keyboard 100 and the numeric keyboard 101 have built-in drivers and can be used when connected to the device.

[0031] like Figure 2 as well as Figure 3 As shown, it is a schematic diagram of the structure of the knob keyboard, the numeric keyboard and the sliding plate body in this embodiment. The outer wall of the knob keyboard 100 and the numeric keyboard 101 near the bottom is provided with a penetrating first sliding groove 104, and the interior of the first sliding grooves 104 on both sides are slidably connected with the sliding plate body 200, and the opposite ends of the sliding plate bodies 200 on both sides are connected. In this embodiment, the knob keyboard 100 and the numeric keyboard 101 can be moved separately on the sliding plate bodies 200 on both sides according to usage habits, and then different positions can be adjusted according to personal usage habits. The posture of both hands can also be changed after long-term work, thereby relieving fatigue of the arms and palms.

[0032] like Figure 2 as well as Figure 5As shown, it is a schematic diagram of the structure of the knob keyboard, the numeric keyboard and the limit plate in this embodiment. The upper ends of the sliding plates 200 on both sides are provided with a plurality of limit grooves 201, and the outer walls opposite to the knob keyboard 100 and the numeric keyboard 101 are provided with second sliding grooves 105. The inner parts of the second sliding grooves 105 on both sides are slidably connected with toggle plates 204. The upper ends of the toggle plates 204 are fixedly connected to the inner top of the return spring 206, and the bottoms of the toggle plates 204 on both sides are fixedly connected to the limit plates 205. In this embodiment, when the knob keyboard 100 or the numeric keyboard needs to be adjusted, the limit plates 205 can be adjusted. When the distance between the knob keyboard 100 and the numeric keyboard 101 is within the range of the knob keyboard 100 and the numeric keyboard 101, the toggle plates 204 are held with both hands and moved upward so that the toggle plates 204 on both sides drive the limit plates 205 to be pulled out from the inside of the limit slot 201 and compress the reset springs 206. At this time, the knob keyboard 100 and the numeric keyboard 101 can slide on the outside of the sliding plates 200 on both sides. After the sliding is completed, release your hands, and the rebound force of the reset springs 206 on both sides makes the toggle plates 204 drive the limit plates 205 to move downward and insert into the inside of the limit slot 201 to limit the knob keyboard 100 and the numeric keyboard 101.

[0033] It is worth noting that the above-mentioned toggle plate 204, limit plate 205 and return spring 206 are the limiting mechanisms in this embodiment, and the limiting mechanisms include but are not limited to the toggle plate 204, limit plate 205 and return spring 206.
