Novel rotary buckling device

The invention provides a novel rotary buckling device. A supporting buffer device is arranged in the bottom of a support and comprises an adjusting screw and a reset spring; the outer side of the support is connected with clamping oil cylinders; each rotary buckling piece comprises a box body, a driving gear, a driven gear, two friction wheels and a driving motor, wherein the driving motor is connected with the driving gear, a locking rod is arranged on one of the friction wheels, and a locking block is arranged at the bottom of the locking rod; a limiting guiding rod is arranged at the bottomof the support, and the limiting guiding rod and the support are fixed through a hook; the bottom of the support is connected with a traveling device; and rollers of the traveling device are arrangedon guide rails of a supporting frame, and the guide rails are movably connected with hook plates. The novel rotary buckling device has the beneficial effects that knurling netlike patterns on the friction wheels is applicable
