U-shaped infolding rotating mechanism with combination of inner chute and semicircle

The invention discloses a U-shaped infolding rotating mechanism with combination of an inner chute and a semicircle, which comprises a rotating shaft, the rotating shaft comprises a rotating mechanism, and the rotating mechanism comprises two groups of rotating frames which are transversely distributed, and a chute movable block and a connection positioning movable block which are longitudinally distributed; two groups of interaction blocks which are transversely distributed are arranged between the chute movable block and the connection positioning movable block, inclined sliding blocks and arc-shaped grooves are respectively arranged on two sides of the interaction blocks, two groups of inner inclined grooves which are respectively inclined inwards are formed in the chute movable block, arc-shaped sliding blocks are arranged on the rotating frame, the arc-shaped sliding blocks slide in the arc-shaped grooves. The inclined sliding block relatively slides in the inner inclined groove to drive the rotating mechanism to ascend, and meanwhile U-shaped inwards-bent rotation with the motion track tangent point unchanged at the angle ranging from 0 degree to 180 degrees is achieved. The rotating frame and the connection positioning movable block are in sliding fit through a sliding column and a curve groove to achieve rotation.
