[0009] The beneficial effects of the utility model are:

[0010] A hook-shaped clamping piece made of elastic material is provided, and the positive electrode cap is connected to the bottom shell by the clamping piece. The clamping piece has a certain elasticity. When the positive electrode cap is pried upward, the pulling force can be used to push the clamping piece to bend and deform inward, thereby eliminating the connection between the positive electrode cap and the bottom shell, making it more convenient to remove the positive electrode cap. At the same time, multiple docking columns and multiple docking rings are provided to realize circuit conduction, making the circuit conduction more stable and less prone to faults such as poor contact. It is simple and practical.
