At this time, the clamping rod 6 automatically extends under the elastic force of the first elastic member 7 and tightly clamps the pin 3, so that the pin 3 is folded and fixed, which is convenient for carrying and storage.

[0027] Example 2

[0028] Based on Example 1, please refer to Figure 4 and Figure 5 A pair of U-shaped support rods 8 are arranged on the back of the charger body 1, and limit plates 9 are rotatably arranged at the upper and lower ends of the U-shaped support rod 8. A plurality of locking balls 10 are arranged on the U-shaped support rod 8 near the left and right sides of the limit plate 9. The locking balls 10 are connected to the U-shaped support rod 8 through a second elastic member 11. A groove matching the locking balls 10 is provided on the limit plate 9. The locking balls 10 are locked into the groove to stabilize the position of the limit plate 9, thereby preventing the limit plate 9 from swinging at will.

[0029] When the charger is finished using, the user can neatly wind the accompanying data cable around the U-shaped support rod 8. At this time, the limit plate 9 is manually rotated to an appropriate position, and the limit plate 9 is fixed by using the card ball 10 and the groove on the limit plate 9, thereby effectively limiting the wound data cable and preventing the data cable from being scattered or falling off during carrying, thereby ensuring the neatness of the data cable and the portability of the charger.

[0030] See also Figure 6 The charger body 1 is provided with two pairs of guide frames 12 symmetrically distributed on the left and right near the interface, and an anti-shell 13 is slidably provided on each pair of the guide frames 12.
