Battery piece bearing device

The embodiment of the utility model provides a battery piece bearing device. The battery piece bearing device comprises a base, a bumping post, a lifting assembly and a transmission assembly, the first surface of the base is slidably connected with at least two oppositely-arranged blocking columns in the first direction, and the first direction is the direction perpendicular to the blocking columns. The lifting assembly is arranged on the second surface of the base, the transmission assembly is connected with the base, the first surface is used for bearing a battery piece, and the first surface and the second surface are two opposite surfaces of the base; the bumping post is connected with the lifting assembly through the transmission assembly; under the condition that the lifting assembly moves in the direction close to the base, the two oppositely-arranged blocking columns are far away from each other under the action of the transmission assembly; and under the condition that the lifting assembly moves in t
