And at the top end of the first threaded rod 1023, there is a handle. When the user holds and rotates the handle, the first threaded rod 1023 can be rotated. When the first threaded rod 1023 rotates, it will push the ball seat 1024 to move up and down. At the same time, the sliding rod 1022 will move along with the up and down movement of the ball seat 1024. The sliding rod 1022 can guide the up and down movement of the ball seat 1024.

[0022] Inside the ball seat 1024, there is a ball head 1026 which can rotate inside the ball seat 1024.

[0024] And by setting four moving frames 1021, it is convenient for the user to separately adjust the height and angle of the four anti-slip plates 1027 to adapt to the rough ground. The user sequentially rotates the four first threaded rods 1023 to respectively push the four ball seats 1024 and the four anti-slip plates 1027 to descend until the four anti-slip plates 1027 all contact the ground and the ground nails 1028 are inserted into the ground. And by rotating the ball head 1026 inside the ball seat 1024, the angle of the anti-slip plate 1027 can be adjusted, which is convenient for effectively supporting the charging device on the rough ground.

[0025] The driving component includes a second threaded rod 1042 rotatably connected inside the storage box 102. Inside the storage box 102, a driving block 1043 is slidably connected, and the outer surface of the second threaded rod 1042 is threadedly connected to the driving block 1043. On both sides of the driving block 1043, driving arms 1044 are hinged. On both sides inside the storage box 102, movable plates 1045 are slidably connected.

[0027] Furthermore, when the user holds and rotates the turning handle 1041, the second threaded rod 1042 will rotate. When the second threaded rod 1042 rotates, the driving block 1043 will move up and down. Furthermore, the two driving arms 1044 will push the two movable plates 1045 to move in opposite directions. When the driving block 1043 rises, the two driving arms 1044 will drive the two movable plates 1045 to approach each other. When the driving block 1043 descends, the two driving arms 1044 will push the two movable plates 1045 to move away from each other.

[0028] Thereby, the moving frame 1021 can be stored or unfolded to reduce the space occupied by the charging device during vehicle-mounted transportation.

After the adjustment is completed, the fastening bolt 1025 can be rotated to fix the ball head 1026 against it. Then, the four first threaded rods 1023 are rotated in turn to push the ball seat 1024 and the anti-slip plate 1027 down until the anti-slip plate 1027 contacts the ground.

[0059] If the ground conditions permit, the ground nails 1028 can also be inserted into the ground to effectively support the charging equipment on rough ground to avoid damage to the charging equipment caused by the charging equipment tipping over due to the rough ground.

[0060] The user pushes the limiting rod 1034 upward to squeeze the first spring 1036 and rotates the grip 1033 to drive the winding roller 1031 to rotate, so as to release the connecting wire of the DC charging gun 701 wound around the outer surfaces of the winding roller 1031 and the fixed rod 1039, and pull the fixed rod 1039 to remove the DC charging gun 701. Then, the user inserts the DC charging gun 701 into the charging hole of the electric vehicle to charge the electric vehicle.
