Through the above arrangement, on the one hand, when the clamping portion 13 is in the first state, due to the gravity action of the battery itself, the central axis of the battery tends to be arranged along the first direction, and the elastic reset piece 17 maintains the clamping portion 13 in the first state by utilizing the elastic action, namely, the central axis of the battery is arranged along the second direction by overcoming the gravity action of the battery. On the other hand, when the second guide 16 passes through the reset segment 223, the elastic reset member 17 assists the clip portion 13 in resetting.

The support plate 18 is thus arranged to prevent the battery from falling out of the clamping portion 13 due to its own weight when the shaft 12 and the clamping portion 13 are in the first state. Of course, in some other embodiments, it may also be adopted that a magnet (not shown) is provided in the clamping portion 13 to attract and fix the battery in the clamping portion 13, so as to avoid the battery from sliding relative to the clamping portion 13 and being separated from the clamping portion 13.
