Description

The present invention relates to the technical field of data line devices, and more particularly to a double pull data line device.

Data lines are an indispensable accessory in modern electronic life, mainly used for charging electronic devices such as mobile phones and cameras and transferring data. Existing data lines generally include a device interface on one end for connecting an electronic device and a USB interface on the other end for connecting a charger. Since the data line is generally long, it is not easy to carry, and if it is placed directly on a table or bag, it is easy to get tangled with the line itself or other objects, causing inconvenience to the user. For this reason, various telescopic double-pull data lines have been devised, placing the mainspring (spiral fragment) in the shell, the mainspring is connected to the winding spool, the wire of the data wire is wound on the winding spool, The basic structure is to place and position a ball on the winding spool. When the data cable is pulled and released, the power of the mainspring rotates the winding spool, and the ball falls along the guide groove into the groove of the card point, stopping the rotation of the winding spool and preventing the data line from being pulled. , the positioning of the data lines is realized. However, such data lines have the following problems. Due to structural problems, the clamping point groove can usually only be installed in one place, so the positioning of the ball can only be achieved after at least one rotation, so the wire corresponding to each stage will be longer and the number of stages will be smaller, so that each stage It is disadvantageous to accurately control the length of the wire rod. At the same time, the ball will fall into the same clamping point groove for each positioning, so the clamping point groove is easy to wear after long-term use, at least affecting the effect of clamping point groove positioning, making the positioning unstable and causing slight vibration In some cases, the ball will fall off, and the data line will be automatically pulled in. If it is heavy, it will not be positioned, and the data line will be unable to be positioned, and will be automatically pulled in when released.

The problem to be solved by the present invention is the deficiencies of the prior art, simple structure, reasonable design, easy installation of at least two clamping point grooves, long service life, long length of each corrugated wire Another object of the present invention is to provide a double-pull data line device capable of more accurately controlling the width.
