USB data cables are used for connection and communication between computers and external devices, and can also be used for charging and external connection of mobile phones. Generally speaking, USB is a widely used external bus standard in the PC field and is used to standardize the connection and communication between computers and external devices. The USB interface supports the plug-and-play and hot-swappable functions of the device. With the rapid development of computer hardware, the application of USB has increased the data transmission speed between external devices. The benefit of the speed increase for users is that they can use it faster. In the process of using the USB cable structure on the market, the length of the USB cable cannot be changed according to the user's needs and can only be repurchased, resulting in a waste of resources. When the USB cable connector is not in use, it is easily damaged by collision or friction, and the USB cable will look untidy due to its long length. Therefore, we propose a more practical USB data cable structure.

Technicians provide a retractable USB data cable structure, which solves the problem that the USB data cable proposed in the above background technology cannot change the length of the USB data cable according to the needs of the user, and can only re-purchase it, resulting in a waste of resources and the unused USB cable connector. It is easy to be damaged due to collision or friction, and it is not neat when used. In order to achieve the above purpose, the USB data cable adopts the following technical solution: a telescopic USB data cable structure, including a USB connector and a fixing buckle. The end of the USB connector is connected to the USB cable body; the fixing buckle is arranged on the USB cable. The turning point of the upper end of the body; the clamp body is fixed on the upper side of the fixed buckle; the USB cable body passes through the fixed buckle; the USB cable body passes through the clamp body. A USB shell is connected to the upper outer side of the USB connector, and a protective sleeve is provided on the outer side of the USB shell; a slip ring is installed on the inside of the top of the protective sleeve, and a semi-closed structure is formed between the protective sleeve and the USB line body through the slip ring; at the same time, the USB connector and the protective sleeve A telescopic structure is formed between them. The bottom cover of the USB cable body is equipped with a suction cup fixing block, and the right end of the suction cup fixing block is connected to the suction cup main body; the external dimensions of the USB cable body are consistent with the opening of the suction cup fixing block; the suction cup main body and the USB cable body are clamped by the suction cup fixing block structure. There is a movable buckle above the clip body, and the connection between the movable buckle and the USB cable body is a sliding connection. A soft pad is connected to the inside of the clip body, and the outside of the cushion is close to the inside of the clip body. A clamping structure is formed between the clip body and the USB cable body. A rotating block is connected to the middle position of the rear end of the clamp body, and a spring piece is provided on the rear side of the rotating block. The upper and lower end surfaces of the spring piece are connected to hand-holding blocks. The connection between the hand-holding block and the spring piece is an elastic connection.

Compared with the existing technology, the above-mentioned USB data cable structure has the following beneficial effects: 1. The device is provided with a fixing buckle. Two sets of fixing buckles wrap the USB data cable inside, and the distance between the two sets of fixing buckles is changed by sliding the fixing buckle. distance, thereby changing the straight length of the USB data cable; 2. Set up a protective cover. When the USB connector is not in use, the sliding protective cover covers the USB connector to prevent collision damage when not in use and extend the service life of the USB connector; Set With the suction cup body, the user can fix the USB data cable body by adsorbing the suction cup body on the desktop or wall, making the entire device relatively tidy. When not in use, the USB data cable body can be adsorbed in a fixed position through the suction cup body to prevent loss; 3. Setting the clip body, the USB data cable body is clamped by the clamp body, so that there will be no relative movement between the clamp body and the USB data cable body, so that the fixed buckle will not move and is fixed on the USB cable body, thereby fixing the straight length of the USB cable body . When it needs to be replaced, the sliding fixing buckle of the clamp body can be opened; there is a soft pad that can protect the USB cable body from being clamped by the clamp body when the clamp body clamps the USB cable body, thereby extending the service life of the USB cable body.
