The invention discloses a linkage combined mechanism which comprises a first joint, a second joint, an upper pipe, a front pipe and a rear pipe. The first joint is hinged to the second joint; the near end of the upper tube is fixedly connected to the first joint; the near end of the rear tube is fixedly connected to the second joint; the near end of the front tube is hinged to the first joint; the second joint is movably connected with a rotating shaft, and the rotating shaft is perpendicular to the front pipe and can rotate around the axial direction of the front pipe. The front pipe is provided with a long groove extending in the length direction of the front pipe, the rotating shaft penetrates through the long groove, a sliding ring is fixed to the portion, located in the front pipe, of the rotating shaft, and the sliding ring is in sliding fit with the front pipe. The folding and unfolding device has the beneficial effect that the folding and unfolding flexibility can be improved.
