S3: when the inside of the charging port (2) is subjected to action in the S1, the inside of the discharging port (3) can be lifted up while the circular plate (501) is lifted up, and the conductive block (603) is driven by the elastic telescopic rod (601) to start moving and move out of the inside of the matching groove (401), so that the discharging port (3) is powered off;
s4: when lithium cell body (1) charges and accomplishes the back, will charge the rifle and pull out from the inside of charging mouth (2), connecting rod (503) can start clockwise rotation under the reaction force that the torsional spring of deformation produced and realize resetting, and then make charging mouth (2) and discharge mouth (3) resume initial condition, shift out in the cooperation groove (401) from inside conducting block (603) of charging mouth (2) promptly, realize stopping the purpose of charging, the inside of cooperation groove (401) is got into to inside conducting block (603) of discharge mouth (3), realize the purpose of discharging.
