[0021] In this embodiment, two handles 2 are fixedly installed on the top of the power supply housing 1, and a cover plate 3 is slidably installed on the top of the power supply housing 1.

[0022] In this embodiment, a sealing plate 6 is detachably installed on the top of the battery compartment 7, and a heat sink 5 is detachably installed on the top of the sealing plate 6 to facilitate heat dissipation when the lithium battery pack 8 is in operation.

[0023] In this embodiment, a heating groove is provided on the top of the battery compartment 7, and an electric heating wire 9 is fixedly installed on the inner side of the heating groove. A heat conduction chamber 10 is provided inside the battery compartment 7, and the heat conduction chamber 10 is filled with heat conduction oil, so as to provide heat to the lithium battery pack 8 in cold weather and prevent the lithium battery pack 8 from malfunctioning due to excessively low temperature.

[0024] In this embodiment, the connecting mechanism includes a movable sleeve 13, a connecting housing 14, a linkage component, and a limiting component. The movable sleeve 13 is slidably sleeved on the limiting post 12. Two receiving grooves are provided on the left inner wall of the positioning groove 11, and two positioning grooves are provided on the rear inner wall of the positioning groove 11. Two protrusions are provided on one side of the movable sleeve 13, and the two protrusions are respectively adapted to the corresponding receiving grooves and positioning grooves. The connecting housing 14 is fixedly installed on the other side of the movable sleeve 13. The linkage component is provided on the inner side of the connecting housing 14, and the limiting component is provided on one side of the linkage component.

[0025] In this embodiment, the linkage component includes an electric push rod 15 and a pressing metal block 16. The electric push rod 15 is fixedly installed on the inner wall of one side of the housing 14, and the pressing metal block 16 is fixedly installed on the output end of the electric push rod 15, so that the pressing metal block 16 can be moved by the electric push rod 15.

[0026] In this embodiment, the limiting component includes four limiting metal strips 17 and four limiting metal blocks 18. Linkage grooves are provided around the perimeter of the connecting housing 14. Limiting metal blocks 18 are slidably installed on the inner side of each of the four linkage grooves. Limiting grooves 19 are provided on the inclined surfaces of each of the four limiting metal blocks 18. The perimeter of the extrusion metal block 16 is set as an inclined surface. Limiting metal strips 17 are fixedly installed on each of the four inclined surfaces. The four limiting metal strips 17 are slidably installed in the corresponding limiting grooves 19, so as to facilitate the movement of the four limiting metal blocks 18 by the extrusion metal block 16.

[0027] In this embodiment, a connecting base 20 is fixedly installed on one side of the power supply housing 1. A connecting port is opened on one side of the connecting base 20. Four connecting slots 21 are opened on the inner side of the connecting port. Four limiting metal blocks 18 are respectively adapted to the corresponding connecting slots 21 to facilitate limiting the connecting housing 14 and prevent it from falling off.

[0028] Working principle: When the ambient temperature is too low, the operator can activate the heating wire 9 via the control panel. The heating wire 9 generates heat, which is transferred to the heat-conducting oil in the heat-conducting chamber 10. The heat-conducting oil can evenly provide heat to the lithium battery pack 8, and the heat will not be too high and damage the lithium battery pack 8. When the power supply device needs to be moved or stacked, the operator first pulls the movable sleeve 13 to move the two protrusions on one side of the movable sleeve 13 away from the two receiving grooves in the positioning groove 11. Then, the operator rotates the movable sleeve 13. When the movable sleeve 13 rotates, the two protrusions align with the two positioning grooves in the positioning groove 11. Then, the operator pushes the movable sleeve... 13. Slide the two protrusions into the corresponding positioning grooves to complete the rotation of the movable sleeve 13. Then align the connecting base 20 with the corresponding connecting housing 14 and connect them. Insert the connecting housing 14 into the connecting base 20. Then start the electric push rod 15 through the control panel. The electric push rod 15 drives the extrusion metal block 16 to move. The extrusion metal block 16 extrudes and extrudes multiple limiting metal blocks 18, causing the multiple limiting metal blocks 18 to slide outward and unfold. The multiple limiting metal blocks slide into the corresponding connecting grooves 21 inside the connecting base 20 to complete the limiting. At this time, the connection between the power devices is tight and not easy to fall off or shift.

[0029] The technological advancements of this invention compared to existing technologies are: it can effectively connect multiple power devices without easily detaching them, making it easier for the power devices to move and stack without shaking or shifting, effectively protecting the power devices. Furthermore, the internal temperature control mechanism can heat the lithium battery pack 8 when the external temperature is too low, preventing issues such as low voltage or power loss due to low temperature, thus increasing the practicality of the device.
