[0024] By arranging the strip slide groove 10, the strip tooth plate 11, the fixed plate 12, the fixed shaft 13, the connecting block 14, the arc tooth plate 15, the rotating rod 16, the positioning plate 17 and the inserting rod 18, it is convenient to rotate the winding disk 7 and position the strip plate 9 after the data cable 4 is wound.

[0025] like Figure 3 As shown, a fixed block 19 is fixedly installed on one side of the strip plate 9, a cavity 20 is opened on the fixed block 19, a circular plate 21 is slidably installed in the cavity 20, a telescopic spring 22 is fixedly installed on the circular plate 21, one side of the telescopic spring 22 is fixedly connected to the inner wall of the cavity 20, a push rod 23 is fixedly installed on the circular plate 21, one end of the push rod 23 extends to the outside of the fixed block 19 and is slidably connected to the fixed block 19, and a spherical block 24 is fixedly installed on one end of the push rod 23;

[0027] like Figure 1 As shown, two buffer sleeves 25 are fixedly installed on the charging head 1, and the two buffer sleeves 25 are symmetrically distributed;

[0028] By providing the buffer cover 25 , the charging head 1 can be protected and the impact force received by the charging head 1 when it falls can be reduced.

[0029] like Figure 3 As shown, the positioning plate 17 is provided with two positioning grooves, and the positioning grooves are adapted to the insertion rod 18;

[0030] By providing the positioning groove, the strip plate 9 can be positioned in cooperation with the insertion rod 18 to prevent the strip plate 9 from rotating.

[0032] The circular groove is provided so as to cooperate with the spherical block 24 to restrict the rotating rod 16 .

[0033] The working principle of the safety charger provided by the utility model is as follows:

[0034] When in use, insert the USB connector 3 into the USB port 2, then connect the charging head 1 to the socket, and connect the Type-C connector 5 to the mobile phone to charge the mobile phone;

[0035] When carrying, the USB connector 3 is pulled out of the USB interface 2, and the strip plate 9 is rotated by the rotating rod 16. The strip plate 9 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the winding reel 7 to rotate, thereby winding the data cable 4. After winding, the rotating rod 16 is pushed to make the connecting block 14 rotate on the fixed shaft 13. After the rotating rod 16 contacts the spherical block 24, the spherical block 24 compresses the telescopic spring 22 through the push rod 23 and the circular plate 21. Then, after the spherical block 24 is facing the circular groove, the elastic force of the telescopic spring 22 makes the spherical block 24 rebound and get stuck in the circular groove, restricting the rotating rod 16. At the same time, during the rotation of the connecting block 14, the arc tooth plate 15 drives the strip tooth plate 11 to move, and the strip tooth plate 11 drives the insertion rod 18 to move, so that the insertion rod 18 is inserted into the positioning plate 17, so that the strip plate 9 can be positioned to avoid the data cable 4 from becoming loose during carrying. Then the charging head 1 and the data cable 4 can be put into the backpack for carrying.
