The tail cover 10 and the support assembly 40 are connected, forming a receiving cavity 12 between them. The snap fastener assembly 20 and the elastic assembly 30 are disposed in the receiving cavity 12, and are kinetically connected. Under the action of the elastic assembly 30, a portion of the snap fastener assembly 20 can pass through the receiving cavity 12, and under the action of an external force, the snap fastener assembly 20 can also be housed in the receiving cavity 12.

[0035] When the bottom cover device 100 of this embodiment is applied to a flashlight, the inner wall of the flashlight body 200 is provided with a slot 210. The shape of the body 200 is not limited to a cylindrical shape, but can also be a square shape or other shapes. When the bottom cover device 100 is installed onto the body 200, the latching assembly 20 is driven by external force to be housed in the receiving cavity 12. After the bracket assembly 40 of the bottom cover device 100 extends into the body 200, the latching assembly 20 is released. At this time, under the action of the elastic component 30, part of the latching assembly 20 extends out from the receiving cavity 12 and is locked into the slot 210 of the body 200, thus connecting the bottom cover device 100 to the body 200.

[0036] When it is necessary to remove the bottom cover device 100 from the main body 200, the buckle assembly 20 is retracted into the receiving cavity 12 by external force.
