The rotating shaft drives the rotating rod 24 to rotate through the mutual meshing of the worm 21 and the worm wheel 27 , and can further rotate through the rotating rod 24 and the pull rod 18 .
工作原理，实施例二与实施例一的区别在于，缓冲环14与缓冲弹簧15的设置，能够便于对电池组进行缓冲，并通过橡胶垫28的作用，从而对电池组进行防护，便于人们使用。Working principle, the difference between the second embodiment and the first embodiment is that the settings of the buffer ring 14 and the buffer spring 15 can facilitate the buffering of the battery pack, and through the function of the rubber pad 28, the battery pack can be protected and convenient for people to use. .
以上所述，仅为本实施例较佳的具体实施方式，但本实施例的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实施例揭露的技术范围内，根据本实施例的技术方案及其发明构思加以等同替换或改变，都应涵盖在本实施例的保护范围之内。The above are only preferred specific implementations of this embodiment, but the protection scope of this embodiment is not limited thereto. Any person familiar with the technical field can, within the technical scope disclosed in this embodiment, implement the method according to this embodiment. Any equivalent substitution or change of the technical solution and the inventive concept of the embodiment shall be covered by the protection scope of the embodiment.
