Among them, the preferable setting range of the elastic member 131 is as follows: within the included angle formed by the limiting rod 133 and the battery taking and placing unit 11, the installation position thereof can be set at any position of the included angle as required. In this embodiment, the elastic element 131 is disposed at the farthest position from the connection position of the limiting rod 133 and the fixing base 111, that is, one end of the elastic element 131 is disposed at the farthest end of the limiting rod 133 away from the fixing base 111, and the other end of the elastic element 131 is disposed at the battery taking and placing unit 11 at a corresponding distance from the fixing base 111.

Wherein, set up contact wheel 132 and realize that the spacing purpose of the relative hold-in range 1213's of gag lever post 133 contact is: when the synchronizing shaft 1212 is in a normal operating state, the meshing teeth 1331 on the limiting rod 133 and the synchronizing shaft 1212 are kept at a reasonable distance, so that the contact wheel 132 is arranged to ensure the normal operation of the synchronizing shaft 1212.
