Supporting piece and energy storage device

The utility model discloses a supporting piece and an energy storage device. The supporting piece comprises a base part, an abutting part and a connecting part. The abutting part is connected to one end of the base part, and the abutting part is contained in the installation groove. The connecting part is connected to one end of the base part, and the connecting part is located on one side of the abutting part. In the mounting process, when the abutting part is contained in the mounting groove, the connecting part is located between the abutting part and the shell, the deformation part deforms after being extruded by the abutting part, the deformed deformation part extrudes the connecting part, and therefore the connecting part is connected with the shell, and mounting of the supporting piece is completed. Fasteners such as adhesives and screws do not need to be used for installation of the supporting piece, and the supporting piece has the advantage of being convenient to install. 本实用新型公开了一种支撑件及储能装置，支撑件包括基部、
