Simple mechanism building platform

The utility model discloses a simple mechanism building platform, which is characterized by comprising a mechanism building part and a drive part. The mechanism building part is provided with a platform panel, at least three first original motive part rotation discs capable of rotating, at least one movable connection disc connected onto the first original motive part rotation disc, a connection rod with one end fixedly connected onto the movable connection disc, at least one sliding block connected with the other end of the connection rod, at least one telescopic planar connection rod connected in a sliding mode with the sliding blocks, and at least one fixed support connected in a rotating mode with one end of the telescopic planar connection rod. The fixed support is movably connected onto the front face of the platform panel. The drive part comprises at least three first chain wheels arranged on the back face of the platform panel and respectively coaxially connected with the at least three first original motive part rotation discs, a chain driving the at least three first chain wheels to rotate at the same time, and a motor driving the chain t move. With the simple mechanism building platform, multiple kinds of sliding block connection rod mechanisms can be easily built.
