The right surface of the connecting block 7 is fixedly connected There is a protrusion 9, and a torsion spring 14 is fixedly sleeved on the outer surface of the connecting rod 11, one end of the torsion spring 14 is fixedly connected to the outer surface of the connecting rod 11, and the end of the torsion spring 14 away from the connecting rod 11 is fixedly connected to the side inner wall of the storage block 6, the outer surface of the connecting rod 11 is rotatably connected to the storage block 6, and an anti-slip groove 16 is provided on the storage block 6, and the outer surface of the anti-slip block 10 is rotatably connected to the anti-slip groove 16, the number of torsion springs 14 is two and distributed front and back, and the number of fixing structures 17 is two and distributed front and back.

[0026] Working principle: Under the action of the protective cover 5, the key 2 can be protected, so as to prevent dust from adhering to the key 2. When the keyboard 1 needs to be used, the protective cover 5 is lifted upwards, so that the protective cover 5 can be separated from the keyboard 1, and the second magnet 4 can be separated from the first magnet 3, so that the key 2 on the keyboard 1 can be operated normally. When the keyboard 1 is used, the protective cover 5 is put back on the keyboard 1, and then the second magnet 4 is brought into contact with the first magnet 3, so that the keyboard 1 is fixed to the protective cover 5 through the magnetism between the first magnet 3 and the second magnet 4, so that the protective cover 5 is not on the keyboard 1. The situation of activity will occur, thereby completing the protection of the button 2, by rotating the positioning block 12, the positioning block 12 is rotated with the connecting rod 11 as the central axis, and at the same time, the connecting rod 11, the anti-dropping block 10 and the limiting block 13 are driven to rotate, and at the same time, the rotating connecting rod 11 can pull the torsion spring 14 on the inner wall of the storage block 6, so that the torsion spring 14 is in a flipped and stretched state, when the rotated positioning block 12 is no longer in contact with the connecting block 7, the connection block 7 and the elastic cleaning brush 8 can be released, and then the protrusion 9 is pulled, so that the connecting block 7 and the elastic cleaning brush 8 can be taken out from the storage groove 15, and then the elastic cleaning brush 8 can be used. The cleaning brush 8 cleans the keyboard 1 and the keys 2. When the elastic cleaning brush 8 is taken out of the storage groove 15, the rotating positioning block 12 is released, so that the torsion spring 14 is no longer restricted to flip and rebound, so that the flipping and rebounding torsion spring 14 drives the connecting rod 11, the anti-dropping block 10 and the limit block 13 to rotate, and then the rotating connecting rod 11 can drive the positioning block 12 to rotate with the connecting rod 11 as the central axis. When the keyboard 1 and the keys 2 are cleaned, the positioning block 12 is rotated again, so that the rotating positioning block 12 drives the limit block 13, the connecting rod 11 and the anti-dropping block 10 to rotate, and the torsion spring 14 is in the flip pulling state. The elastic cleaning brush 8 and the connecting block 7 are in an extended state, and then the elastic cleaning brush 8 and the connecting block 7 are reinserted into the storage groove 15. Then the rotating positioning block 12 is released, so that the torsion spring 14 is no longer restricted to flip and rebound, so that the flipping and rebounding torsion spring 14 drives the anti-falling block 10, the connecting rod 11 and the limiting block 13 to rotate, and then the rotating limiting block 13 drives the positioning block 12 to rotate with the connecting rod 11 as the central axis. When the rotated positioning block 12 contacts the connecting block 7, the connecting block 7 is fixed, so that the connecting block 7 and the elastic cleaning brush 8 will not be separated from the storage groove 15, and the storage of the connecting block 7 and the elastic cleaning brush 8 is completed.

[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
