A connection handle 8 is installed on one side of the frame 1, and an auxiliary component 15 for assisting in storage and carrying is arranged at the end of the connection handle 8. The auxiliary component 15 includes a connection column 1501, a positioning disk 1502, an extension column 1503 and a connecting clamping plate 1504. A positioning disk 1502 is arranged on the outer surface of the connection column 1501. An extension column 1503 is installed on the end surface of the connection column 1501, and a connecting clamping plate 1504 is rotatably installed on the outer surface of the extension column 1503. A crank 9 is arranged outside the connecting clamping plate 1504. The inside of the crank 9 is of a hollow structure, and the crank 9 is of a frustum shape. One end of the crank 9 is snap-connected to the positioning disk 1502. By manually rotating the crank 9 by the user, the connection handle 8 can be controlled to rotate to achieve hand-cranked power generation. When hand-cranked power generation is performed, 1-3 rotations per second are sufficient. The faster the hand-cranked speed, the greater the generated current. The generated electricity is directly stored in the built-in power lithium battery 11. Power generation can be performed by rotating the crank in both forward and reverse directions. When the 220V switch is pressed, the power display meter 3 displays the battery power and the generated voltage in real time. When the right green grid is full, it means full charge. When the portable power supply does not need to be used, the crank 9 can be pulled to the outside, so that the inner surface of the end of the crank 9 can be snap-connected to the connecting clamping plate 1504, and the connecting clamping plate 1504 is rotatably connected to the extension column 1503. Thus, the crank 9 can rotate about the connection column 1501 through the connecting clamping plate 1504 and the extension column 1503, which is convenient for storing the crank 9 and convenient for the user to carry the emergency power supply. In addition, when the crank 9 is used, the crank 9 can be reset so that the crank 9 can be positioned and snap-connected to the positioning disk 1502 on the outer surface of the connection column 1501, which is convenient for the user to drive the connection handle 8 to perform hand-cranked power generation through the crank 9.

The threaded rod 1702 is installed in the fixing plate 1701 in a threaded manner, and the positioning plate 1703 is rotatably arranged at the end of the threaded rod 1702. By manually rotating the threaded rod 1702 inside the fixing plate 1701, the positioning plate 1703 rotatably connected to the threaded rod 1702 can be driven to move in position. Two groups of positioning plates 1703 are provided, and the placement surface required for the emergency power supply can be clamped and fixed by the approach and separation of the positions of the two groups of positioning plates 1703, which is convenient for maintaining stability during hand-cranking power generation of the emergency power supply and avoiding the instability and tipping of the emergency power supply during hand-cranking, which may affect power generation.
[0026] In summary, for this hand-cranking power generation emergency portable power supply, first according to Figures 1-4In the structure shown, when the light switch is pressed, the built-in emergency light will light up. When the power is normal, it can provide continuous lighting for more than 48 hours (5200 mAh model) or 96 hours (10400 mAh model). When the 220V switch is pressed, the 220V connection socket 7 outputs 220V 150W AC power, which can be used to power electrical appliances within 150W for emergency use. When generating power by hand-cranking, the speed can be 1 - 3 rotations per second. The faster the hand-cranking speed, the greater the generated current.

When the 220V switch is pressed, the power display meter 3 will display the battery power and the generated voltage in real time. When the green grid on the right is full, it means it is fully charged. When the crank handle 9 is folded back, it needs to be pulled outwards and then folded back. When charging with a charger, you can observe the charging status according to the indicator light on the charger. When the indicator light is red, it is charging. When the indicator light turns green, the charging is completed. In addition, by manually turning the crank handle 9 by the user, the connecting handle 8 can be controlled to rotate, realizing hand-cranking power generation. When generating power by hand-cranking, the speed can be 1 - 3 rotations per second. The faster the hand-cranking speed, the greater the generated current. The generated electricity is directly stored in the built-in power lithium battery 11. It can generate electricity by hand-cranking in both forward and reverse directions. When the 220V switch is pressed, the power display meter 3 will display the battery power and the generated voltage in real time. When the green grid on the right is full, it means it is fully charged. When it is not necessary to use the portable power supply, the crank handle 9 can be pulled towards the outside, so that the inner surface of the end of the crank handle 9 can be engaged with the connecting card plate 1504, and the connecting card plate 1504 is rotatably connected to the extension column 1503. Then the crank handle 9 can rotate about the connecting column 1501 through the connecting card plate 1504 and the extension column 1503, which is convenient for storing the crank handle 9 and convenient for the user to carry the emergency power supply. In addition, when using the crank handle 9, the crank handle 9 can be reset and engaged with the positioning disk 1502 on the outer surface of the connecting column 1501, which is convenient for the user to drive the connecting handle 8 to generate power by hand-cranking through the crank handle 9. Finally, by manually rotating the threaded rod 1702 inside the fixed plate 1701, the positioning plate 1703 rotatably connected to the threaded rod 1702 can be driven to move. And there are two groups of positioning plates 1703. By moving the two groups of positioning plates 1703 closer and farther away, the placement surface required for the emergency power supply can be clamped and fixed, which is convenient for keeping stable when generating power by hand-cranking the emergency power supply and avoiding the instability caused by the hand-cranking of the emergency power supply, resulting in tipping and affecting power generation.
