That is to say, when the button 31 is subjected to an external force, the button 31 moves towards the locking portion 32 and compresses the first elastic portion 33, so that the resilient force of the first elastic portion 33 increases, under the pushing of the button 31, the locking portion 32 retracts into the accommodating space 113 from the top end of the shell 1, so as to separate the battery pack 100 and the battery compartment from each other, at the same time, the second elastic portion 34 is compressed, so that the resilient force of the second elastic portion 34 increases. When the external force acting on the button 31 disappears, under the action of the resilient force of the first elastic portion 33, the button 31 moves away from the locking portion 32, so that the button 31 is separated from the locking portion 32, under the action of the resilient force of the second elastic portion 34, the top end of the locking portion 32 extends out of the accommodating space 113. After the external force acting on the button 31 disappears, the first elastic portion 33 and the second elastic portion 34 can also have a certain resilient force, so as to ensure the position stability of the button 31 and the locking portion 32, and the shaking of the button 31 and the locking portion 32 can be avoided.
