Structure of mechanism |
| Function |
The motion device described in the patent relates to a lifting platform for the height adjustment of load. The lifting platform is based on a scissor mechanism with 7 links and 9 joints, which is driven by a cam. The degree of freedom of the mechanism is F = 1. |
