[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0026] In the description of the present utility model, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when used.

[0027] See also Figures 1 to 4 , shows a movable wrist rest provided by the present embodiment, including a base plate 1, a sliding plate 2 and a wrist support cover 4, a limiting column 5 is fixed on the base plate 1, an avoidance hole 21 is opened on the sliding plate 2, the limiting column 5 is located in the avoidance hole 21, and the sliding plate 2 can slide horizontally relative to the base plate 1 under the limiting action of the limiting column 5 (that is, the sliding plate 2 can slide forward and backward and left and right relative to the mouse pad).
[0028] Furthermore, the movable wrist support of the present embodiment further includes a limit plate 3, the limit plate 3 and the bottom plate 1 are arranged at intervals, and the limit column 5 is located between the bottom plate 1 and the limit plate 3. The cooperation between the limit plate 3 and the bottom plate 1 can limit the range of motion of the sliding plate 2 in the vertical direction, and the wrist support cover 4 is fixedly covered on the sliding plate 2, so that the wrist support cover 4 can only move in the space between the bottom plate 1 and the limit plate 3 and will not be lifted upward. Preferably, the thickness of the sliding plate 2 should be slightly smaller than the spacing between the limit plate 3 and the bottom plate 1, so that the wrist support cover 4 can float up and down a small distance, thereby avoiding excessive friction between the sliding plate 2 and the bottom plate 1, which affects the sliding of the wrist support cover 4 in the horizontal direction.
[0029] In this embodiment, two spaced limiting posts 5 are fixed on the bottom plate 1, and the limiting posts 5 extend vertically upward from the top surface of the bottom plate 1. Two grooves 31 are provided on the bottom surface of the limiting plate 3 at positions corresponding to the two limiting posts 5; the limiting posts 5 are embedded in the grooves 31 to connect the bottom plate 1 and the limiting plate 3. It is easy to understand that two grooves can also be provided on the top surface of the bottom plate 1, and two limiting posts can be provided on the bottom surface of the limiting plate 3 to achieve the same function.
[0030] In this embodiment, the limiting column 5 and the groove 31 are fastened together by means of interference fit. In some other preferred embodiments, glue bonding can also be used. When there is only one groove and limiting column, the two can also be connected by threads.
[0031] The sliding plate 2 is provided with two avoidance holes 21 spaced apart from each other, and the two limit posts 5 are respectively located in the two avoidance holes 21; the two ends of the limit plate 3 are respectively fixed to the top ends of the two limit posts 5. In order to increase the smoothness of the wrist support cover 4 in the process of sliding forward and backward and left and right, in this embodiment, the limit posts 5 are cylindrical and the avoidance holes 21 are circular or elliptical.
[0032] A sliding sheet is pasted on the top surface of the limiting plate 3. Since the top surface of the sliding sheet is in direct contact with the bottom surface of the wrist support cover 4, the friction coefficient between the contact surfaces can be reduced, thereby increasing the smoothness of the wrist support cover 4 when sliding relative to the limiting plate 3. Preferably, the sliding sheet is a Teflon sliding sheet, and four recessed points 32 are provided on the top surface of the limiting plate 3 for pasting the Teflon sliding sheet.
[0033] The wrist support cover 4 can be an integrally formed structure or a structure composed of two parts. In this embodiment, the wrist support cover 4 includes a cover plate 41 and a flexible cover layer 42, and the flexible cover layer 42 covers the cover plate 41. The material of the flexible cover layer 42 is a flexible material such as sponge, gel or silicone. Preferably, the flexible cover layer 42 is a raised structure with a rounded chamfer at the edge. Through this design, the contact area between the side of the flexible cover layer 42 and the user's wrist can be increased, so that when the wrist moves or swings, the wrist support cover 4 can be better stressed and then move or swing with the wrist.
[0034] In order to assemble the sliding plate 2 to the bottom of the cover plate 41 , an annular convex edge 411 is extended downward from the edge of the cover plate 41 in this embodiment, and the sliding plate 2 is fixedly embedded in the annular convex edge 411 .
[0035] When the movable wrist rest is placed on a mouse pad for use, a friction layer is provided on the bottom surface of the bottom plate 1 to increase the friction of the movable wrist rest on the mouse pad to prevent the bottom plate 1 from sliding relative to the mouse pad.
[0036] See also Figure 5 and Figure 6The present embodiment further provides a mouse pad, including a mouse pad body 200 and a movable wrist support 100, wherein the movable wrist support 100 is placed on the mouse pad body 200 (eg Figure 5 Alternatively, the bottom plate 1 in the movable wrist support 100 is embedded in the mouse pad body 200 (as shown in FIG. Figure 6 shown).
[0037] In summary, the movable wrist support 100 of this embodiment is placed or pasted on the mouse pad 200, or the bottom plate 1 is buried in the mouse pad 200. When the user moves and swings the mouse, the static friction between the wrist and the wrist support cover 4 can drive the wrist support cover 4 to move horizontally relative to the bottom plate 1 and the mouse pad 200. Since the wrist and the wrist support cover 4 are relatively still, the wrist skin does not generate sliding friction with the wrist support cover 4 and the mouse pad 200, thereby avoiding "mouse hand" and joint damage after long-term use.
[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
