[0018] See also Figure 1-5 The utility model provides a card reader with a protective bracket, including a card reader body 1, an end of the card reader body 1 is fixedly connected to a USB terminal 2, and a memory card slot is provided on a side wall of the card reader body 1, and a protective bracket 7 is movably installed on the outer side of the card reader body 1, and the end of the protective bracket 7 is fixedly connected to a limiting piece 5, the limiting piece 5 covers the outer side of a turntable 3, and the turntable 3 is fixedly installed on the outer surface of the card reader body 1, and a limiting block 4 is fixedly installed on the outer side of the turntable 3, and a limiting groove 6 is provided on the inner wall of the limiting piece 5.
[0019] Working principle: When in use, the protective bracket 7 covers the outer side of the USB terminal 2 to protect the USB terminal 2;
[0020] The protective bracket 7 is a rotating structure with the turntable 3 as the center. The rotation angle of the protective bracket 7 on the outside of the card reader body 1 is limited by the limit groove 6 and the limit block 4; the excessive rotation of the protective bracket 7 on the outside of the card reader body 1 can be avoided. When the protective bracket 7 is rotated, the limit groove 6 is slidably set on the outside of the limit block 4. When the card reader body 1 is idle, the protective bracket 7 is rotated so that the protective bracket 7 quickly and accurately covers the outside of the USB terminal 2.
[0021] As a preferred implementation, the protection bracket 7 is a "U"-shaped structure made of metal material, and a protection area 8 is opened inside the protection bracket 7.
[0022] One end of the limiting piece 5 away from the protection bracket 7 is arranged in an arc shape, and a circular slot is provided inside the limiting piece 5 , and the circular slot is adapted to the size of the rotating disk 3 .
[0023] The protection bracket 7 is a "U"-shaped structure, covering the outer side of the USB terminal 2, and can protect the USB terminal 2 from pressure.
[0024] As a preferred embodiment, the turntable 3 is clamped inside the circular clamping slot, and a limiting groove 6 is provided on the inner wall surface of the circular clamping slot. The limiting groove 6 is arc-shaped, and the limiting groove 6 and the turntable 3 are concentric circle structures.
[0025] As a preferred embodiment, the size of the limit slot 6 is adapted to the limit block 4, and the limit block 4 is clamped inside the limit slot 6. At the same time, the rotation angle of the protective bracket 7 outside the card reader body 1 is limited by the limit slot 6 and the limit block 4.
[0026] The protection bracket 7 is a rotating structure with the turntable 3 as the center, and the rotation angle range of the protection bracket 7 is 0-90°.
[0027] like Figure 2-5 As shown: the rotation angle of the protection bracket 7 on the outside of the card reader body 1 is limited by the limit slot 6 and the limit block 4. When the protection bracket 7 is rotated, the setting of the limit slot 6 and the limit block 4 can quickly and accurately cover the protection bracket 7 on the outside of the USB terminal 2; and the friction between the circular card slot and the turntable 3 and the friction between the limit block 4 and the limit slot 6 are used to ensure the stability of the protection bracket 7 when it is stationary.
