In the specific implementation process, the anti-skid lines arranged on the rotating knob 7 can increase the friction between the fingers and the rotating knob 7, prevent accidental operation caused by hand slipping when the user adjusts the height or angle of the hand rest plate 5, the hand rest plate 5 is made of polypropylene material, which has the characteristics of light weight, durability, easy cleaning and the like, at the same time, the upper surface of the hand rest plate 5 is provided with a hand rest pad made of memory cotton material, the memory cotton can be adaptively adjusted according to the individual hand shape, provide better support and comfort, and help to reduce the fatigue feeling of the wrist when typing for a long time, the cross-sectional size of the dust cover 2 is slightly larger than that of the keyboard body 1, which ensures that the dust cover 2 can completely cover the keyboard body 1, effectively prevents dust and sundries from entering the inside of the keyboard body 1, and the small gap between the edge of the dust cover 2 and the keyboard body 1 also helps to maintain air circulation, avoid overheating in the inside of the keyboard body 1, and the bottom end of the keyboard body 1 is provided with a supporting leg, the design of the supporting leg makes the keyboard can maintain a certain inclination angle when in use, which is more in line with the principle of ergonomics, helps to reduce the fatigue feeling of the wrist and arm, and improves the typing efficiency and comfort.

[0030] Working principle:

[0031] Step one: when it is needed to install the dust cover 2 on the keyboard body 1, the user aligns the magnet piece 4 at the bottom of the dust cover 2 with the magnetic attraction slot 3 opened on the magnetic block 6 at one side of the keyboard body 1, due to the magnetic attraction force between the magnet piece 4 and the magnetic attraction slot 3, the dust cover 2 is automatically attracted and firmly fixed on the keyboard body 1 without the need for additional fixing devices or operations, when it is needed to disassemble the dust cover 2 to use the hand rest plate 5, the user only needs to gently pull the dust cover 2 away from the keyboard body 1, and the magnetic connection between the magnetic attraction slot 3 and the magnet piece 4 makes the disassembly process convenient and stable.

[0032] Step two: the hand rest plate 5 on the upper surface of the dust cover 2 is connected to the end of the dust cover 2 away from the magnet piece 4 through a hinge, so that the hand rest plate 5 can flip up and down within a certain range, the bottom of the hand rest plate 5 is connected to the support rod 13 through the support block 14, the other end of the support rod 13 is connected to the sliding block 10 through the hinge seat 12, the sliding block 10 is threadedly connected with the threaded rod 8 in the installation slot 16, at the same time, the installation slot 16 is also provided with a guide rod 9 to provide stable guidance for the sliding block 10, the user rotates the rotating knob 7 to drive the threaded rod 8 to rotate, the rotation of the threaded rod 8 will drive the sliding block 10 to move back and forth along the threaded rod 8 under the guidance of the guide rod 9, since the sliding blocks 10 are connected through the connecting rods 11, therefore, when one sliding block 10 moves, the other sliding blocks 10 and the support rods 13 above them will also move synchronously, so as to change the angle of the hand rest plate 5.

[0033] Step three: the hand rest plate 5 is made of polypropylene material, which is light, durable and easy to clean, the memory cotton material hand rest pad installed on its upper surface can adapt to individual hand shapes, providing better support and comfort, reducing wrist fatigue during long-time typing, the cross-sectional size of the dust cover 2 is slightly larger than that of the keyboard body 1, ensuring that the dust cover 2 can completely cover the keyboard body 1, effectively preventing dust and debris from entering the inside of the keyboard body 1, at the same time, the small gap between the edge of the dust cover 2 and the keyboard body 1 helps to maintain air circulation, avoiding overheating inside the keyboard body 1, the design of the support feet at the bottom end of the keyboard body 1 makes the keyboard maintain a certain inclination angle during use, which is more in line with the principle of ergonomics, helping to reduce the fatigue of the wrist and arm, improving typing efficiency and comfort.
