The extension and the contraction of the piston rod of the double-head hydraulic cylinder 23 can realize the lifting of the battery pack 1, and simultaneously, the transportation of the battery pack 1 is convenient, and the battery pack 1 is convenient to replace on the way.
These and other changes can be made to the apparatus in light of the above-detailed description. While the above detailed description describes specific embodiments of the invention and describes the best mode contemplated, no matter how detailed the above appears in this document, the system can be practiced in many ways. Although the details of the locally-based support device may vary considerably in its implementation details, it is still included in the devices disclosed herein. As noted above, the particular technical term used in describing a particular feature or aspect of the present apparatus is not meant to be redefined herein to be defined as an aspect of the particular feature, or system associated with the term. In general, the terms used in the following claims should not be construed to limit the system to the specific embodiments disclosed in the specification unless the above detailed description section explicitly defines such terms. Therefore, the actual scope of the system includes not only the disclosed embodiments, but also all equivalent ways of implementing or realizing the device covered by the claims.
