An assembly space is provided inside the supporting assembly component, the limiting component is provided in the supporting assembly component, an installation space is provided on the surface of the limiting component, the snap-on component is provided in the limiting component, the shell is fixed by the snap-on component, the reset component is connected to the snap-on component, and the snap-on component is reset by the reset component.

[0033] In this embodiment, the supporting assembly component includes an upper shell 110 and a lower shell 120, the upper shell is provided with an installation space, the two ends of the upper shell are provided with snap-in holes, the two ends of the upper shell are provided with threaded holes, the lower shell is connected to the upper shell, the lower shell is provided with an assembly space, the two ends of the lower shell are provided with threaded holes, and the threaded holes and the threaded holes of the upper shell are on the same axis.

[0034] In this embodiment, the limiting assembly includes a limiting plate 210, which is arranged on the surface of the lower shell body. An installation space is arranged on the surface of the limiting plate. Limiting columns 211 are arranged on both sides of the limiting plate. There are two pairs of limiting columns. A limiting block 212 is arranged in the center of the limiting plate. The limiting block and the limiting column limit the clamping assembly.

[0035] In this embodiment, the clamping assembly includes a clamping plate 310, which is provided with a pair of clamping plates, which are symmetrically arranged on the surface of the limiting plate, and a clamping portion 311 is provided on one side of the clamping plate. The clamping portion is arranged in the clamping hole of the upper shell, and the shape of the clamping portion is rectangular. A slope is provided on one side of the clamping portion, and the clamping portion is guided by the slope. A pair of connecting columns 312 are provided on the other side of the clamping plate, and an installation space is provided on the surface of the connecting column.

[0036] In this embodiment, the reset assembly includes a reset spring 410, which is provided with a pair of reset springs, which are respectively sleeved on the connecting columns of the clamping plate, and the reset spring abuts against the clamping plate.

The clamping plate moves inward under the guidance of the inclined surface of the clamping portion and the action of the surface of the assembly component, and the return spring is deformed by the force and then contracts. When the clamping portion reaches the fixed position and the clamping portion does not abut against the assembly component, the return spring resets, driving the clamping plate to pop outward, and the clamping plate is clamped with the clamping hole of the assembly component, thereby fixing the battery pack in the assembly component.
