[0027] See also Figure 5 The flexible pad body 12 in this embodiment includes a flannel layer 121 for supporting and keeping warm in winter, so as to improve the supporting comfort. Correspondingly, a sponge layer 122 is arranged at the lower end of the flannel layer 121 to achieve improved supporting flexibility. A leather layer 123 is arranged at the lower end of the sponge layer 122, so that when used in summer, the leather layer 123 can be used to absorb moisture and permeate to ensure the dryness of the wrist and reduce the influence of sweat. Correspondingly, rubber bands 124 are installed at the four corners of the leather layer 123 to realize the convenient combination of the flexible pad body 12 and the wrist support body 11 board.

[0028] Specifically, the flannel layer 121, the sponge layer 122 and the leather layer 123 are stacked from top to bottom, and the flannel layer 121, the sponge layer 122 and the leather layer 123 are sewn and connected with each other by stitches, so as to conveniently form the flexible pad main body 12, realize flexible support and meet the use needs of different users; the rubber bands 124 are correspondingly bonded and connected along the four corners of the leather layer 123, and the four rubber bands 124 can be combined with the supporting feet 115 provided at the four corners of the bottom of the wrist rest plate 111, so as to cooperate with the elasticity of the four-corner rubber bands 124, and can be hung and combined with the four-corner supporting feet 115, so that the flexible pad main body 12 and the wrist rest main body 11 can be conveniently combined and used.

[0029] Here’s how it works:

[0030] When the keyboard wrist rest is to be used, the wrist rest body 11 can be placed in front of the keyboard to be against and flush with the front of the keyboard. In this way, the user can place the wrist on the top plate of the wrist rest plate 111 when using the keyboard to achieve auxiliary support for the wrist, thereby providing a support point for the wrist to avoid wrist fatigue and pain caused by long-term keyboard operation, improve the comfort of use, and facilitate keyboard operation. Secondly, because the wrist rest plate 111 is made of stone material as a whole, it not only has efficient and stable supporting properties, but also will not collapse and be unable to rebound during long-term use. The overall structure is sturdy and durable, which greatly improves the service life of the keyboard wrist rest. During use, the alkaline sweat on the wrist is not easy to cause damage to the wrist rest body 11 Corrosion, thereby further extending the service life, and the wrist support body 11 is slightly cool as a whole to facilitate heat dissipation, which meets the use in hot weather. At the same time, in order to prevent the wrist support plate 111 from causing friction at the edge corners of the wrist support plate 111 when it contacts and supports the user's wrist, a chamfered strip 112 is provided on the front side of the top plate of the wrist support plate 111, and a first curved surface 113 and a second curved surface 114 are provided on the left and right sides of the chamfered strip 112, so that the top plate surface of the wrist support plate 111 is smooth and free of barbs as a whole, thereby achieving stable anti-friction supporting activities. If the supporting height of the wrist support plate 111 needs to be adjusted, support feet 115 can be inserted into the four corners of the bottom of the wrist support plate 111 accordingly, so that the support feet 115 change the height of the wrist support plate 111 to meet the supporting needs of different users;

[0031] If the keyboard wrist rest is used in winter or summer, in order to avoid the wrist rest plate 111 made of stone material causing some problems to the wrist, the flexible pad body 12 can be placed on the upper end of the wrist rest body 11 to achieve flexible support. First, when combining the flexible pad body 12 with the wrist rest body 11, the rubber bands 124 provided at the four corners of the leather layer 123 need to be pulled respectively to stretch the rubber bands 124 to the support feet 115 at the bottom of the wrist rest plate 111. In this way, the rubber bands 124 can be hung to the outside of the support feet 115 with their own elasticity. In this way, when the rubber bands 124 at the four sides are hung corresponding to the support feet 115 on the four sides of the bottom of the wrist rest plate 111, the flexible pad body 12 can be stably placed on the upper end of the wrist rest plate 111 to ensure the stability of the auxiliary support of the flexible pad body 12 and reduce the occurrence of the phenomenon of the flexible pad body 12 slipping off and falling during the movement of the wrist.

[0032] When the flexible pad body 12 and the wrist rest body 11 are combined, the flannel layer 121 inside can be used for supporting in winter to keep the wrist warm and reduce the occurrence of wrist coldness. In summer, the flexible pad body 12 can be turned over as a whole so that the leather layer 123 is on the supporting surface. In this way, combined with the moisture absorption and breathability of the leather layer 123 itself, the formation of sweat on the wrist can be reduced and the wrist can be kept dry. Secondly, the sponge layer 122 placed between the flannel layer 121 and the leather layer 123 can increase the supporting flexibility to a certain extent, thereby improving the comfort of using the keyboard wrist rest and avoiding the problem that the wrist rest body 11 made of stone cannot fully meet the supporting needs of different users.

[0033] The utility model provides a keyboard wrist rest, which can realize efficient anti-collapse support under the support of a wrist rest plate 111 made of stone material, and is resistant to corrosion by alkaline sweat, greatly prolonging the overall service life, and can meet the use in various environments, and is more suitable for summer and hot weather. The overall texture is cool and easy to dissipate heat, and a flexible pad main body 12 is provided, that is, a flannel layer 121, a sponge layer 122 and a leather layer 123 can be combined, and the two sides can be flipped to meet the use of different people and different environments, and the rubber bands 124 arranged on the four sides of the leather layer 123 can be hung and combined with the supporting feet 115 arranged at the four corners of the bottom of the wrist rest plate 111, so that the flexible pad main body 12 can be conveniently disassembled and cleaned as a whole, thereby achieving the advantages of flexible support and flipping and switching for use according to seasons.
