When the battery needs to be replaced, the unlocking mechanism pushes the lock connecting rod 22 to ascend, so that the lock tongue 23 rotates, the first opening 212 is opened, at the moment, the battery pack is moved again to enable the lock shaft to withdraw from the lock groove 211, the support shaft withdraws from the support groove 31, the battery pack is driven to move downwards, the lock shaft withdraws from the first opening 212, and the support shaft withdraws from the second opening 32, so that the battery pack can be detached.

While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and the scope of the utility model is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the principles and spirit of the utility model, but such changes and modifications fall within the scope of the utility model.
