Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Refer to Figures 1-4, A multi-functional computer USB flash drive that prevents falling off, including a USB flash drive main body 1 and a USB plug 2 fixed to its upper end. A rubber strip 4 is fixedly connected to the surface of the USB flash drive main body 1 to play an anti-slip role when the user holds the USB flash drive main body 1. A protective cover 3 is provided at the upper end of the USB flash drive main body 1 to provide external protection for the USB plug 2. A slot is provided at the lower end of the protective cover 3, and the upper end of the USB plug 2 slides and extends into the slot. Semi-circular abutting blocks 6 are provided on both sides of the USB plug 2 to play an anti-loosening role in cooperation with the friction between the USB plug 2. One end of the abutting block 6 away from the USB plug 2 is fixedly connected to the inner side wall of the slot;

[0022] In this embodiment, two connecting rods 5 are fixedly connected to the lower end of the protective cover 3 to prevent the protective cover 3 from loosening and falling off. The two connecting rods 5 are respectively located on both sides of the USB plug 2. A connecting groove corresponding to the connecting rod 5 is provided at the upper end of the USB flash drive main body 1. The lower end of the connecting rod 5 slides and extends into the connecting groove. A connecting ring is fixedly sleeved on the upper end of the connecting rod 5 to improve the firmness between the connecting rod 5 and the protective cover 3. The upper side wall of the connecting ring is fixedly connected to the lower end of the protective cover 3;

[0023] In this embodiment, a sliding groove is provided on the inner side wall of the connecting groove. A sliding block 11 is slidably connected to the inner side wall of the sliding groove to drive the clamping block 12 to move. A first spring 13 is fixedly connected between the sliding block 11 and the inner side wall of the sliding groove to drive the sliding block 11 to move back to its original position. A semi-circular clamping block 12 is fixedly connected to the side of the sliding block 11 away from the first spring 13 to cooperate with the clamping groove to lock the position of the connecting rod 5. A clamping groove corresponding to the clamping block 12 is provided on the outer side wall of the connecting rod 5. One end of the clamping block 12 away from the sliding block 11 penetrates through the sliding groove and slides and extends into the clamping groove;

[0024] In this embodiment, two guide rods 14 are slidably inserted into one end of the sliding block 11 close to the first spring 13 to play a role in guiding the movement of the sliding block 11. The two guide rods 14 respectively slide through the two first springs 13 and are fixedly connected to the inner side wall of the sliding groove. A limiting block 15 is fixedly connected to the lower end of the sliding block 11 to cooperate with the limiting groove to limit the movement stroke of the sliding block 11. A limiting groove corresponding to the limiting block 15 is provided at the inner bottom of the sliding groove. One end of the limiting block 15 away from the sliding block 11 slides and extends into the limiting groove;

[0025] In this embodiment, a storage groove is provided inside the protective cover 3 and near the top. A support rod 7 is provided in the storage groove and is used to drive the wire reel 8 to rotate and reset. The front and rear ends of the support rod 7 are respectively rotatably connected to the inner two sides of the storage groove. A second spring 16 is sleeved on one end of the support rod 7 and is used to drive the support rod 7 to rotate and reset. The second spring 16 is a torsion spring, and the two ends of the second spring 16 are respectively fixedly connected to the outer side wall of the support rod 7 and the inner side wall of the storage groove. A wire reel 8 is fixedly sleeved on the support rod 7 and is used to wind the connecting rope 9. The connecting rope 9 is wound around the wire reel 8 and is used to prevent the protective cover 3 from loosening or falling off. One end of the connecting rope 9 is fixedly connected to the wire reel 8, and the other end of the connecting rope 9 slidably penetrates through the protective cover 3 and is fixedly connected to the outer side wall of the USB flash drive body 1. A fixing ring 10 is fixedly sleeved on the end of the connecting rope 9 away from the wire reel 8 and is used to improve the firmness between the connecting rope 9 and the USB flash drive body 1. One side of the fixing ring 10 is fixedly connected to the outer side wall of the USB flash drive body 1.

[0026] In this embodiment, first, the protective cover 3 is sleeved on the USB plug 2 of the USB flash drive body 1, and the protective cover 3 plays a safety protection role for the USB plug 2. When the protective cover 3 is sleeved on the USB plug 2, the protective cover 3 is pushed in the direction of the USB flash drive body 1. At this time, the USB plug 2 will be inserted into the slot and abutted against the abutting block 6. The frictional force between the abutting block 6 and the USB plug 2 prevents the protective cover 3 from loosening or falling off. When the protective cover 3 is pushed, the connecting rod 5 is driven by the protective cover 3 to be inserted into the connecting groove. During the insertion process, it will abut against the semi-circular surface of the semi-circular block 12, thereby pushing the block 12 to move in the direction of the chute. The block 12 drives the slider 11 to slide, and the first spring 13 is compressed by the slider 11. When the connecting rod 5 is completely inserted in place, the elastic force and restoring force of the first spring 13 drive the slider 11 to move back to its original position, and the block 12 is driven by the slider 11 to move into the card slot, thereby locking the position of the connecting rod 5 and preventing the connecting rod 5 from loosening from the connecting groove, and further preventing the protective cover 3 from falling off the USB plug 2; when the user pulls out the protective cover 3, the connecting rope 9 can prevent the protective cover 3 from falling off or being lost. Since the connecting rope 9 is wound around the wire reel 8, pulling the connecting rope 9 can extend its length to avoid affecting the user's pulling out of the protective cover 3. When the connecting rope 9 is pulled, the wire reel 8 will be driven to rotate. The wire reel 8 drives the support rod 7 to rotate, and the support rod 7 rotates to compress the second spring 16. When the user releases the connecting rope 9, the elastic force and restoring force of the second spring 16 drive the support rod 7 to rotate back to its original position. The support rod 7 drives the wire reel 8 to rotate back to its original position, and the wire reel 8 rotates to wind up the connecting rope 9 to avoid the connecting rope 9 from becoming loose and getting entangled, which is convenient for the user to wind up the connecting rope 9.

[0027] As described above, the USB flash drive body and the USB plug are existing mature technologies, and their working principles and internal structures are known to those skilled in the art. This application only utilizes their functions and does not improve their internal structures. Therefore, no detailed description will be given.

[0028] As described above, it is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
