DETAILED DESCRIPTION

[0017] The utility model is described in detail below in conjunction with the accompanying drawings.

[0018] Example 1

[0019] like Figure 1-4 As shown, a USB flash drive comprises a USB flash drive housing 1 and a double-head USB flash drive 2, wherein the double-head USB flash drive 2 is arranged inside the USB flash drive housing 1, protective components 3 are arranged at both ends of the USB flash drive housing 1, and a finger ring 4 is connected to one side of the USB flash drive housing 1.

[0020] The USB disk housing 1 has a USB storage slot 101 on the inner side, a card slot 102 on both sides of the middle part of the USB disk housing 1 near the USB storage slot 101, a slide slot 103 on both sides of the USB disk housing 1 near the card slot 102, and a plurality of limiting slots 104 on both sides of the USB disk housing 1.

[0021] Both sides of the double-head USB flash drive 2 are connected with a card block 21, and the card block 21 is embedded in the inner side of the card slot 102 to slide.

[0022] Arc grooves are formed on the outer sides of the circumferences of the clamping blocks 21 .

[0023] The protective component 3 includes a USB flash drive protective shell 31, and both ends of one side of the USB flash drive protective shell 31 are connected to hinged rods 3101. A pulling block 32 is provided at the other end of the hinged rod 3101 away from the USB flash drive protective shell 31, and a connecting rod 3201 is connected to the inner side of the pulling block 32, and a through hole of the hinged rod 3101 is arranged on the outer hinge connection of the connecting rod 3201, and a pushing plate 3202 is connected to the other end of the pulling block 32 away from the connecting rod 3201, and the pushing plate 3202 is embedded in the limiting groove 104 of the USB flash drive shell 1 and slides back and forth.

[0024] The outer side of the pulling block 32 is connected with a connecting rod 33, and the connecting rod 33 is embedded in the slide groove 103 of the USB flash drive housing 1 and slides back and forth. The other end of the connecting rod 33 away from the pulling block 32 is connected with a chuck 34, and the chuck 34 cooperates with the block 21 of the double-head USB flash drive 2.

[0025] If students need to use the USB flash drive to extract the traditional music clips that the teacher has taught before, they first push the push disks 3202 at both ends forward, so that the push disks 3202 at both ends move from left to right along the limiting groove 104 of the USB flash drive shell 1, and at the same time, they also drive the hinged rod 3101 and the USB flash drive protective shell 31 to move to the right together, and as the push disks 3202 at both ends move to the rightmost end along the limiting groove 104, the USB flash drive protective shell 31 can be flipped downward by ninety degrees, so that the head of one side of the double-headed USB flash drive 2 is exposed and inserted into the USB socket of the computer, so as to extract the traditional music clips that the teacher needs to lecture on, and after the extraction is completed, the USB flash drive protective shell 31 can be rotated upward by ninety degrees, and the USB flash drive protective shell 31 can be returned and installed on one side of the double-headed USB flash drive 2, so as to protect the head of the double-headed USB flash drive 2 and prevent damage.

[0026] When the double-headed USB flash drive 2 needs to be disassembled, the USB flash drive protective shells 31 at both ends can be pulled in opposite directions at the same time, and the pulling blocks 32, the connecting rods 33 and the chucks 34 are also driven to move outward at the same time, so that after the chucks 34 at both ends are pulled out of the arc grooves of the card blocks 21 of the double-headed USB flash drive 2, the double-headed USB flash drive 2 drives the card blocks 21 to slide out of the USB flash drive placement slot 101 along the card grooves 102, thereby facilitating the disassembly of the double-headed USB flash drive 2, and a finger ring 4 is provided on one side of the USB flash drive housing 1 for students to wear on their fingers to prevent the double-headed USB flash drive 2 from being lost.

[0027] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
