The portable terminal also comprises a lock cover connected with the pushing button, and a torsional spring is arranged between the lock cover and the pushing button, so that the lock cover and the pushing button can rotate along the spring-body axis of the torsional spring; when the torsional spring is reset, vertical distance between one end of the lock cover and the cell or the body arranged the compression spring is smaller than the distance that the pushing button inserts into the clamp slot. The lock cover in the present invention can achieve double-clamping at the axial direction for the cell and the main machine body. The pushing button can tightly lock the cell and the main machine body even if the portable terminal is dropped down or impacted. The cell can be taken from the main machine body only by adding certain torque to the torsional spring while in the assembling or disassembling operation, operation is simple and convenient.
