The plurality of wire-receiving wheels 41 are respectively slidably and interlacedly connected with the inner cavities of the plurality of storage grooves, and are used for winding and storing the connection wires 2 and the interface wires 3. The ends of the connection wires 2 and the interface wires 3 connected to the charger body 1 are located inside the storage groove, and a groove is provided on one side of the wire-receiving wheel 41 close to the inner wall of the storage groove for facilitating the passage of the connection wires 2 and the interface wires 3, and the depth of the storage groove is one greater than the thickness of the wire-receiving wheel 41. times, so that the wire reel 41 will not squeeze the line inside the storage slot after being installed inside the storage slot; the outer wall of the wire reel 41 is provided with multiple positioning grooves at equal intervals, and the positioning assembly 42 is located inside the positioning grooves. The positioning assembly 42 can position the wire reel 41 at multiple points, so that the connection wire 2 and the interface wire 3 can be stored inside the wire reel 41 when not in use; both sides of the charger body 1 are provided with placement grooves that are connected to the storage groove, which are used to place the connectors of the connection wire 2 and the interface wire 3 respectively. The opening of the placement groove further improves the storage effect of the connection wire 2 and the interface wire 3. The outer wall of the wire reel 41 is provided with a groove, and the extrusion assembly 43 is located inside the groove.
