The following is a summary description of the stretching, housing and positioning of the data line 2:

when not charging, as shown in fig. 2-3 and 7, the data line 2 is received in the cylindrical projection 433, and the tab 21 is engaged with the engaging groove 122.

When charging is required, the joint 21 is removed from the engaging groove 122, the joint 21 is pulled by force to extend the data wire 2, so that the joint 21 can be inserted into the socket, when the joint 21 is pulled to extend the data wire 2, the data wire 2 drives the rotary disc 43 to rotate and deform the coil spring 44, at this time, as shown in fig. 13, the ball 4334 rotates along the outer groove 4331, the rotation direction of the ball 4334 on the outer groove 4331 is shown by an arrow at the first blocking portion 4336 in fig. 13, when the joint 21 is pulled to a proper position, the length of the joint can be inserted into the socket, at this time, as the tensile force stretching the joint 21 is weakened (usually, the user pulls the joint 21 by hand), under the restoring force of the coil spring 44, the rotary disc 43 is driven to rotate in the opposite direction, at this time, the ball 4334 rotates in the outer groove 4331 in the opposite direction, but, due to the blocking effect of the first blocking portion 4336, the ball 4334 rolls into the V-shaped groove 4333, and falls into the limit position (in fig. 13, the position of the ball 4334) of the V-shaped groove 4333, the limit position limits the rolling of the ball 4334, so that the data line 2 is positioned, and the telescopic line 2 does not move to facilitate charging.

If, during stretching of the joint 21, the joint 21 cannot be stretched in one step to a desired position in case the data line 2 needs to be stretched long, during which a plurality of stretches are required. When the ball 4334 falls into the limit position of the V-shaped groove 4333, it can be considered that the ball is stretched for a certain distance, and the joint 21 is further stretched, the ball 4334 rolls out of the limit position from the arrow direction of the fourth block 4339 in fig. 13 due to the blocking effect of the fifth block 4335, the ball 4334 rolls into the inner groove 4332, the ball 4334 rolls into the connecting groove 4330 due to the blocking effect of the second block 4338, and rolls into the outer groove 4331 from the arrow direction of the third block 4337, and thus, the joint 21 is stretched to a suitable length for being inserted into the socket many times in a round process. Finally, the balls 4334 are defined at the defined positions so that the telescopic wire 2 does not move for charging.

After the charging is completed, the connector 21 is pulled out from the socket, and at this time, the data line 2 is stored. After the connector 21 is pulled out of the socket, a pulling force is applied to the connector 21 to pull the ball 4334 out of the limited position and roll into the inner groove 4332, but the pulling force is not a continuous pulling force, so that the ball 4334 cannot roll into the outer groove 4331 (for example, the ball 4334 rolls into the outer groove 4331, and after the pulling force is removed, the ball 4334 rolls into the limited position again), after the pulling force disappears, the rotary disc 43 is driven to rotate in the opposite direction under the restoring force of the coil spring 44, and the ball 4334 rolls in the inner groove 4332 automatically along the direction indicated by the arrow at the second blocking portion 4338 until the restoring force of the coil spring 44 disappears, so that the data line 2 is accommodated in the cylindrical protrusion 433 again.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
