The bottom plate of the battery compartment 3 is generally inclined and tilted downward from the front to the back, so as to prevent the risk of the battery slipping out of the battery compartment 3. Therefore, through such an arrangement, the front bottom and the rear top are locked, so that the battery 5 is locked more securely.

[0028] Specifically, the driver 8 is fixedly mounted on the outer wall of the battery compartment 3, the bottom plate or the top plate of the battery compartment 3 is fixedly mounted with a movable sleeve 11, and a corresponding position of the bottom plate or the top plate of the battery compartment 3 is provided with a through opening, the locking rod 13 is movably mounted on the movable sleeve 11, one end of the locking rod 13 is a matching portion, the matching portion is connected to the push rod 9, and the other end of the locking rod 13 is a locking portion, which can extend from the opening to match with the lock slot 6 or retract from the opening to separate from the lock slot 6. The locking rod 13 is movably mounted using the movable sleeve 11, so that the movement of the locking rod 13 is smoother and more reliable. Except that the locking portion can enter and exit the battery compartment 3 through the opening, the other components of the locking mechanism 7 are all located outside the compartment and will not interfere with the battery replacement operation of the battery 5. The movable sleeve 11 of the utility model is a hollow structure, the movable sleeve 11 is sleeved on the locking rod 13, and the locking rod 13 moves up and down relative to the movable sleeve 11, and the movement method is reliable and simple.
