A tooth plate 28 is meshed on the outer wall of the bottom end of the gear 7, and the tooth plate 28 is slidably connected to the inner wall of the left end of the reading and writing device 1. The movement of the tooth plate 28 drives the movement of the dustproof plate 29. A dustproof plate 29 is fixedly connected to the outer wall of the left end of the tooth plate 28. The dustproof plate 29 moves to the upper end of the reading and writing device 1 when the reading and writing device 1 is not in use to prevent dust from the reading and writing device 1. The inner wall of the left end of the dustproof plate 2 is elastically connected to a limiting component through a spring 12, and an adjustment component is rotatably connected to the inner wall of the upper end of the reading and writing device 1.
[0030] Reference Figure 1 and Figure 4 The adjustment component includes a rotating shaft 15, and a carrying plate 10 is fixedly connected to the outer wall of the rotating shaft 15. The carrying plate 10 provides space for placing the card reading plate 11. The carrying plate 10 drives the card reading plate 11 to rotate and adjust the angle of the card reading plate 11 through the rotation of the rotating shaft 15. The card reading plate 11 is fixedly connected to the upper outer wall of the carrying plate 10. The card reading plate 11 is used to identify the card. The rear end outer wall of the rotating shaft 15 is fixedly connected to the limit plate 3. The rotating shaft 15 stops rotating by fixing the limit plate 3. The upper inner wall of the reading and writing device 1 is elastically connected with an insert block 4 through a spring 14. The upper right outer wall of the insert block 4 is inclined. The right end outer wall of the embedded block 4 is slidably connected to the upper inner wall of the reading and writing device 1. When the limit plate 3 is rotated counterclockwise, the left end inner wall of the limit plate 3 squeezes the upper right outer wall of the embedded block 4, and the embedded block 4 is squeezed away from the left end inner wall of the limit plate 3. After the limit plate 3 stops rotating, the embedded block 4 is clamped on the left end inner wall of the limit plate 3 under the elastic force of the spring 2 14 to fix the limit plate 3. The right end outer wall of the embedded block 4 is slidably connected to the left end inner wall of the limit plate 3. One end of the spring 2 14 is fixedly connected to the upper inner wall of the reading and writing device 1, and the other end of the spring 2 14 is fixedly connected to the left end outer wall of the embedded block 4.

After the limit plate 3 is rotated to the most comfortable and convenient angle for the customer, the insert block 2 4 is clamped on the left inner wall of the limit plate 3 under the elastic force of the spring 2 14 to fix the limit plate 3, which is convenient for the customer to use. When the read-write device 1 is not needed, the insert block 13 is moved upward to leave the upper left inner wall of the read-write device 1, and the dustproof plate 2 is moved toward the center. The dustproof plate 2 drives the tooth plate 5 to move and the gear 7 rotates. The rotation of the gear 7 drives the tooth plate 2 8 to move, so that the dustproof plate 2 9 moves in the direction of the dustproof plate 2. After the front outer wall of the dustproof plate 2 contacts the rear outer wall of the dustproof plate 2 9, the insert block 13 is released to fix the position of the dustproof plate 2, so that the position of the dustproof plate 2 9 is fixed at the same time, and the read-write device 1 can be dustproof.
