[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] See Figure 1-6 , The present invention provides a technical solution: a shielding protection device for the magnetic head of a credit card machine, comprising a credit card machine body 1, an operation button 2 is provided on the front surface of the credit card machine body 1, and a display screen is provided on the top surface of the credit card machine body 1 3. The display screen 3 is located on the top of the operation button 2, a swiping area 4 is provided on the top of the card swiping machine body 1, and a swiping jack 5 is provided on the top of the swiping area 4.

[0026] A fixed block 6 is provided on both sides of the swiping jack 5, and a sliding groove 7 is opened inside the fixed block 6. The inner cavity of the sliding groove 7 is slidably connected with a slider 8, and one side of the slider 8 is fixedly connected with a connecting block 9 , The side of the connecting block 9 away from the slider 8 penetrates to the outside of the fixed block 6 and is fixedly connected to the shielding protection device body 10, and the side of the fixed block 6 away from the card insertion socket 5 is provided with an activity adapted to the slider 8 Slot 11.

[0027] The shielding protection device body 10 includes a substrate layer 1001, an electroplated metal shielding layer 1002, a metal core layer 1003, an outer insulating layer 1004, and a carbon steel wear-resistant layer 1005. One side of the substrate layer 1001 is provided with an electroplating metal shielding layer 1002 The side of the electroplated metal shielding layer 1002 away from the base layer 1001 is provided with a metal core layer 1003, the side of the metal core layer 1003 away from the electroplated metal shielding layer 1002 is provided with an outer insulating layer 1004, and the outer insulating layer 1004 is away from the metal core layer 1003 A carbon steel wear-resistant layer 1005 is provided on one side of the

[0028] In the present invention: the back surface of the card machine body 1 is provided with a groove 12, and the inner wall of the groove 12 is provided with striped bumps 13. The use of the groove 12 and the striped bumps 13 is convenient for the user to use the card machine body 1 When held in the hand for operation, the striped bumps 13 can increase the friction between the hand used and the credit card machine body 1, so that the credit card machine body 1 will not easily slip from the user's hand, which facilitates the user to operate the credit card machine body 1 .
