Among them, the two rotating walls 222 are respectively arranged at both ends of the connecting wall 221. By setting the connecting wall 221, it is convenient to connect with the pressing member 21; by setting the rotating wall 222 on the side away from the rotating direction of the U disk body 3, it is convenient to drive the U disk body 3 to rotate; by setting the rotating wall 222 on the side close to the rotating direction of the U disk body 3, the accommodating space can be further closed. As a convertible embodiment, it is also possible that only one rotating wall 222 is provided, which is arranged on the side away from the rotating direction of the U disk body 3. As a convertible implementation, the two rotating walls 222 may not be disposed at the ends of the connecting wall 221, but may be disposed close to the ends.

[0065] like Figure 4 As shown, two rotating walls 222 are provided near the USB interface 32 , and the cross section of the rotating member 22 is U-shaped; one rotating wall 222 is provided near the Type C interface 33 , and the cross section of the rotating member 22 is L-shaped.

Among them, a first limiting groove 213 is provided on the inner side of the pressing member 21, and a second limiting groove 223 is provided on the side of the rotating member 22 away from the U disk body 3. One end of the elastic member 23 abuts against the first limiting groove 213, and the other end abuts against the second limiting groove 223; the elastic member 23 is a spring. By setting the elastic member 23, the pressing member 21 can be automatically reset, and the operation is simple; by setting the first limiting groove 213 and the second limiting groove 223, the elastic member 23 can be limited to prevent the elastic member 23 from being displaced after being used for a period of time, the pressing member 21 cannot be reset, and the U disk body 3 cannot be rotated out normally. As a convertible embodiment, it is also possible that the elastic member 23 is not provided, and the pressing member 21 is manually reset. As a convertible embodiment, the first limiting groove 213 and the second limiting groove 223 may not be provided, and the two ends of the elastic member 23 may be respectively fixed to the inner side of the pressing member 21 and one side of the rotating member 22 by gluing or welding. As a convertible embodiment, only the first limiting groove 213 or only the second limiting groove 223 may be provided.

[0067] The protrusions 212 on the pressing portion 2 may be provided only on the outer wall corresponding to the elastic member 23. As a changeable embodiment, the protrusions 212 may be provided on the outer wall of the pressing portion 2.

[0068] like Figure 5 As shown, the USB flash drive body 3 in this embodiment has a second state in which it is completely rotated to the inside of the housing 1 under the action of an external force. By completely placing the USB flash drive body 3 in the accommodation space of the housing 1 and sealing both ends with the pressing portion 2, there is no need to use an outer cover, which can prevent the outer cover from being lost; at the same time, the interfaces at the two ends of the USB flash drive body 3 are located in the housing 1, which is not easily damaged by external influences when not in use, and dust and dirt are not easy to enter the interfaces.

[0069] like Figure 3-Figure 4 As shown, a first limiting member 211 is provided on the side of the pressing member 21 close to the elastic member 23, and a second limiting member 13 cooperating with the first limiting member 211 is provided at a corresponding position of the side wall of the shell 1, which is suitable for limiting the end of the pressing member 21 from extending out of the shell 1. Among them, the first limiting member 211 and the second limiting member 13 are both limiting inclined surfaces. In the second state, the elastic member 23 is in a slightly compressed state, and the elastic member 23 has an outward elastic force on the pressing member 21. By setting the first limiting member 211 and the second limiting member 13, the end of the pressing member 21 close to the elastic member 23 can be set close to the shell 1, and the end of the pressing member 21 can be prevented from extending out of the shell 1; by adopting the limiting inclined surface for limitation, the structure is simple, the contact area is large, and the limiting effect is good.

[0070] The pressing member 21 in this embodiment is also provided with a first stopper 211 on the side away from the elastic member 23, and a second stopper 13 cooperating with the first stopper 211 is provided at a corresponding position on the side wall of the housing 1. The elastic member 23 can make the end away from the elastic member 23 also close to the housing 1, and can prevent the end of the pressing member 21 from extending into the housing 1. By providing the first stopper 211 at both ends of the pressing member 21, the pressing member 21 can be limited from continuing to rotate outward under the elastic force of the elastic member 23, that is, Figure 2 The clockwise direction of the pressing member 21 does not affect the inward rotation of the pressing member 21. Figure 2 In the counterclockwise direction, the USB flash drive body 3 is rotated out of the housing 1. As a convertible embodiment, the first limiter 211 may be provided only at one end of the pressing member 21 close to the elastic member 23, or the first limiter 211 may be provided only at one end of the pressing member 21 away from the elastic member 23.

[0071] like Figure 3-Figure 4As shown, the side wall of the housing 1 includes a side wall body, and a first opening 11 is provided on the side wall body; a protrusion 31 is provided at a position corresponding to the first opening 11 of the USB flash drive body 3, and in the second state, the protrusion 31 is arranged flush with the side wall body. Further, in the second state, the rotating wall 222 is also arranged flush with the side wall body. By arranging the protrusion 31 on the USB flash drive body 3 and arranging the rotating wall 222 flush with the side wall body, the first opening 11 can be closed as much as possible in the second state to prevent dust from entering the storage space. As a convertible embodiment, it is also possible that the protrusion 31 is arranged beyond the side wall body.

[0072] like Figure 5 As shown, the length of the rotating wall 222 corresponding to the Type C interface 33 is set to be longer, and the length of the rotating wall 222 corresponding to the USB interface 32 is set to be shorter, so that the rotating walls 222 corresponding to different interfaces can drive the USB flash drive body 3 to rotate and close the first opening 11 as much as possible in the second state.

[0073] like Figure 3-Figure 4 As shown, five first positioning structures 14 are provided in the housing 1, and the USB flash drive body 3 is provided with a second positioning structure 34 rotatably connected to the first positioning structure 14. By providing the first positioning structure 14 and the second positioning structure 34, it is convenient to rotate the USB flash drive body 3 out of the housing 1.

As a convertible embodiment, the first positioning structure 14 can also be a positioning hole, and the second positioning structure 34, the third positioning structure 214, and the fourth positioning structure 224 can be a positioning column.

[0075] like Figure 4 As shown, the first positioning structure 14, the second positioning structure 34, the third positioning structure 214 and the fourth positioning structure 224 are arranged along the longitudinal axis of the housing 1, and the elastic member 23 is arranged away from the longitudinal axis of the housing 1. By eccentrically arranging the elastic member 23, it is convenient to drive the rotating member 22 to rotate.

[0076] The working principle of the USB flash drive in this embodiment is as follows:

[0077] like Figure 5 As shown, in the second state, the USB flash drive body 3 is completely located in the accommodating space of the housing 1;

[0078] like Figure 6 As shown, when external force acts on the pressing member 21, the rotating member 22 rotates and drives the end of the USB flash drive body 3 to rotate out of the first opening 11. At this time, the end of the USB flash drive body 3 is just located outside the housing 1, forming a first state;

[0079] like Figure 7 As shown, an external force is applied to the end of the USB flash drive body 3, and the USB flash drive body 3 continues to rotate outward until the USB flash drive body 3 and the housing 1 are at 90 degrees, forming a third state, which is the use state of the USB flash drive;

[0080] When external force acts on the two sets of pressing parts 2, the USB disk body 3 rotates in the opposite direction, and the USB disk body 3 is screwed into the housing 1 and returns to the second state.
