Referring to Figures 12-15, it should be noted that during the rotation of the spool, the positioning column reciprocates in a straight line along the guide groove 11. In order to facilitate understanding of the movement of the locating column on the positioning track plate when the spool rotates Trajectory, the dotted line in the figure is the movement trajectory of the positioning column when the winding reel does not move.

Referring to FIG. 12 , when the data wire needs to be extended, the data wire is pulled to extend outward so as to connect the electronic device.

During the extension process of the data wire, the winding reel rotates clockwise, the mainspring 4 stores energy, the positioning column 21 is located in the first track groove 31, the winding rotates, and the inner wall of the first track groove 31 pushes the positioning column 21 Therefore, due to the guiding action of the guide groove 11, the fixed position is moved linearly.

Referring to FIG. 13 , after the data guide 5 protrudes for a certain length, the data wire 5 needs to be positioned for the use of the data guide.

Remove the pulling force exerted on the data guide 5. At this time, the spring 4 releases the energy accumulated when the data line is extended, the spring 4 rotates counterclockwise, and drives the winding reel to rotate counterclockwise synchronously. At this time, due to the positioning The diameter of the movement track circle formed by the lower end of the groove is smaller than the diameter of the maximum movement track circle formed by the inner wall of the first track slot. Therefore, when the positioning slot 25 rotates counterclockwise, the lower side wall of the positioning slot 25 can be free from the position of the positioning column 21. The inner wall passes through, and the positioning column 21 is guided into the bottom of the positioning groove 25 along the lower side wall of the positioning groove 25. The positioning column 35 positions the winding reel 6 through the positioning track plate 3, prevents its rotation, and completes the locking of the length of the data wire. It should be noted that, during the positioning process, since the winding reel rotates counterclockwise by a certain angle, the data winding will be retracted by a certain amount, and the retracted length depends on the rotation angle of the winding reel.

Referring to Fig. 14, when the charging or data transmission of the electronic device is completed, the data wire is separated from the electronic device and the data wire is retracted to the reel, including two processes. First, the reel is rotated clockwise to make the positioning The post 21 is separated from the positioning slot, and then the winding reel is rotated counterclockwise to make the positioning post enter the first track slot. The specific process is as follows:

First, a pulling force is applied to the data wire to make the spool 6 rotate clockwise. At this time, the positioning column 21 is stationary, the spool 6 continues to rotate, the first guide surface 36 is in contact with the positioning column 21, and the first guide surface 36 Turn clockwise to push the positioning post 21 into the second guide groove.

Then, the pulling force exerted on the data wire is cancelled, the spring 4 releases energy, the winding disc 6 rotates counterclockwise, and the outer wall of the first track groove pushes the positioning column to make a linear reciprocating motion until the spring 4 is completely released, and the data cable Rewind on the spool.

Referring to Figure 15, when the data guide needs to be stretched out again during the retraction process, a pulling force is applied to the data wire again. At this time, the positioning column is located in the first track groove, the winding reel rotates clockwise, and the spring 4 stores energy. The first track groove drives the positioning column to move back and forth in a straight line, and the outer wall of the first track groove drives the fixed position to move linearly. When the second guide surface 37 hits the positioning column 21, the positioning moves to the direction of the second track groove 32. The circular trajectory formed by the tips of the two rail partitions 39 is the same as the circular trajectory formed by the highest point of the second guide surface 37. Therefore, when the second rail partition 39 rotates clockwise, the third guide surface 392 can self-align the post The outside passes through, guides the positioning column into the second track groove, continues to pull the data guide, and the positioning column continues to move on the second track.
