[0059] The motion assembly 6 has two functions, the first of which is transportation. Specifically, the components are placed on the mounting positions on the movable plate 62, and then the cover plate 63 covers the upper end surface of the movable plate 62, and then the movable plate 62 is driven to move relative to the connecting plate 61, and the movable plate 62 can transport the components to the storage space of the box body 12 for standby. When assembly is required, the glue spraying structure 64 will first spray glue to the preset positions of each component, and then the cover plate 63 is opened.

Specifically, the inner side of the side plate 13 is provided with a groove; the end of the movable plate 62 is provided with a protrusion adapted to the groove. The protrusion can be inserted into the groove, and at this time, the movable plate 62 has a limiting and fixing effect on the side plate 13.

[0060] As a specific implementation of the embodiment of the present invention, refer to Figures 1 to 9 , the safety component 4 is electrically connected to the energy supply component 2.

A clamping ring is disposed at one end of the tension spring away from the sealing plate 42. Specifically,

[0063] When the sealing plate 42 is connected to the locking member 43 and seals the open end of the container 41, the electric clamping column passes through the clamp ring of the tension spring in the up and down direction. When the temperature is higher than the preset value, the temperature sensor transmits a signal to the electric clamping column structure, and the electric clamping column expands and contracts after receiving the signal. When it expands and contracts to a certain extent, the electric clamping column separates from the tension spring. At this time, the sealing plate 42 releases the seal on the open end of the container 41, so that the fire extinguishing ball 43 falls into the box body 12 and plays a role in extinguishing fire.
