The first output terminal 18 is an electrical power output portion of the first battery pack 16, and is typically implemented by a metal terminal or connector, and may be a plug or an interface for transmitting the electrical power of the first battery pack 16 to an external device or circuit. In a general dry battery or storage battery, an output terminal is often made of a metal material such as zinc, copper, iron, etc., and has good electrical conductivity and high temperature resistance.
It should be noted that the electrical connection refers to a connection established between two or more electrical components or circuits through an electrical conductor. This connection allows current, charge or signals to pass between the various elements. The electrical connection may be made by conductive materials such as wires, cables, circuit boards, and the like. In the circuit, the electrical connection between the elements is a necessary condition for current flow and signal transmission, ensuring the effective transmission of electric energy or information.

The detachable connection of the gear mechanism and the force application mechanism provides greater flexibility for the operation of the power supply equipment, and is convenient for a user to control the trigger module.
It should be noted that, the battery power shortage refers to a phenomenon that the battery loses electric energy due to internal self-discharge, temperature, storage conditions and other factors under the condition that the battery has no external load, and even if the battery is not connected to any load, chemical reaction inside the battery still causes loss of electric charge, so as to reduce the available electric energy of the battery. The battery is not charged in time after being used, sulfation is easy to occur on the battery, lead sulfate crystals are attached to the polar plate, an ionization channel is blocked, the charging is insufficient, and the capacity of the battery is reduced. The longer the power-deficient state idle time, the more the battery is damaged. Therefore, the method reduces the battery power shortage time and is an important technical means for effectively prolonging the service life of the equipment.
In an alternative embodiment of the present invention, as shown in fig. 5, a connection port is formed through the placement plate 21, and a second output terminal 19 is disposed on the second battery pack 17, where the second output terminal 19 passes through the connection port and is electrically connected to the first battery pack 16.
Specifically, by setting the connection port, when the placement plate 21 is at the initial position, the second output terminal 19 can pass through the connection port and is electrically connected with the first battery pack 16, so that the second battery pack 17 can supply power to the first battery pack 16 in time, equalization of electric energy in the battery is realized, the number of times of cyclic charge and discharge of the power supply device is slowed down, and the service life of the battery is prolonged. By providing the placement plate 21, not only is electrical interconnection between components facilitated, but connection and disconnection are also made easier, improving the flexibility of the power supply apparatus. Meanwhile, the surface area of the placing plate 21 which can dissipate heat is increased in the battery compartment 15, heat can be generated when the battery works, and the heat can be transferred to the surrounding environment more effectively by increasing the heat dissipation area, so that the heat dissipation performance of the system is improved. Maintaining a proper temperature is critical to the performance and life of the battery, and by increasing the heat dissipation efficiency, the problem of reduced life of the battery due to high temperature can be reduced.
