[0022] See also Figure 1-7The utility model provides a card reader with an anti-dropping component, including a card reader body 2, the top of the card reader body 2 is fixedly connected to a USB terminal 1, and the outer side of the USB terminal 1 is covered with a protective cap 3, and an opening 4 is provided on the top of the protective cap 3, and guide blocks 6 are fixedly installed on both sides of the bottom of the protective cap 3; a memory card slot is provided at the tail of the card reader body 2, and guide grooves 8 are provided on both sides of the card reader body 2, the guide grooves 8 are adapted to the size of the guide blocks 6, and the guide blocks 6 are slidably arranged inside the guide grooves 8.

[0023] Working principle: When in use, hold the protective cap 3 and lift it upwards, so that the protective cap 3 covers the outer side of the USB terminal 1 and is fixed through the upper limit hole 5 and the top lock column 10. The protective cap 3 protects the USB terminal 1; the protective cap 3 will not fall off and can protect the USB terminal 1 for a long time.

[0024] At the same time, the protective cap 3 is separated from the outer side of the USB terminal 1 and fixed through the bottom locking column 7 and the lower limit hole 9, so that the USB terminal 1 and the protective cap 3 are separated, which is convenient for plugging the USB terminal 1 into the computer.

[0025] As a preferred embodiment, the size of the opening 4 is larger than that of the USB port 1 , and the opening 4 is rectangular.

[0026] The protective cap 3 moves downward, and the opening 4 is arranged so that there is no motion interference between the protective cap 3 moving downward and the USB terminal 1 .

[0027] As a preferred implementation, the top of the guide block 6 is fixedly connected to the top lock column 10 , and the bottom of the guide block 6 is fixedly mounted with a bottom lock column 7 , which has the same size and structure as the top lock column 10 .

[0028] An upper limit hole 5 is opened on the inner upper side of the guide groove 8, and a lower limit hole 9 is opened on the inner lower side of the guide groove 8. At the same time, the guide block 6 moves upward and the top lock column 10 thereon is inserted into the upper limit hole 5, and the guide block 6 moves downward and the bottom lock column 7 thereon is inserted into the lower limit hole 9.

[0029] like Figure 2-6 As shown: when the protective cap 3 is being lifted or lowered, the guide block 6 is slidably set inside the guide groove 8, which can limit and guide the vertically moving protective cap 3 to ensure the stability of the protective cap 3 when being lifted or lowered, and at the same time, the protective cap 3 will not fall off from the USB terminal 1.

[0030] As a preferred embodiment, the bottom lock column 7 is made of rubber material and has a trapezoidal cross-section. The surface of the bottom lock column 7 is provided with an inclined surface 71, and the bottom of the bottom lock column 7 is provided with an arc surface 72. At the same time, the bottom lock column 7 is interference fit with the lower limit hole 9.

[0031] As a preferred embodiment, the protective cap 3 is a "U"-shaped structure made of acrylic material, and the protective cap 3 covers the outer side of the USB terminal 1 and is fixed by the upper limit hole 5 and the top lock column 10. At the same time, the protective cap 3 is detached from the outer side of the USB terminal 1 and is fixed by the bottom lock column 7 and the lower limit hole 9.

[0032] When the protective cap 3 is at rest, the stability of the protective cap 3 can be ensured by the following two methods:

[0033] First, the guide block 6 is slidably disposed inside the guide groove 8; there is friction between the guide block 6 and the guide groove 8, which can limit the protective cap 3;

[0034] Second: when the protective cap 3 is unfolded to cover the USB terminal 1, the top lock column 10 is inserted into the upper limit hole 5. The cross section of the top lock column 10 is an isosceles trapezoid. When the top lock column 10 is inserted into the upper limit hole 5 under force, the friction between the top lock column 10 and the upper limit hole 5 is used to ensure the stability of the protective cap 3 when it is stationary.

[0035] When the protective cap 3 shrinks to expose the USB terminal 1, the bottom lock column 7 is inserted into the lower limit hole 9, and the friction between the bottom lock column 7 and the lower limit hole 9 is used to ensure the stability of the protective cap 3 when it is stationary.
