The present invention discloses an arc short tube gripping lifting mechanism, which comprises a fixed plate and clamping assemblies, wherein strip-shaped holes are longitudinally processed on the fixed plate, the clamping assembly comprises a pair of clamping seats, the lower end of the clamping seat is provided with a threaded rod penetrating through the strip-shaped hole, the upper end is a rectangular block, the side wall is processed into an arc surface, the arc surfaces of the pair of the clamping seats are assembled opposite to each other, the threaded rod ends extending out of the strip-shaped holes are provided with locking nuts, and both sides of the fixed plate are provided with hanging rings for lifting. With the technical scheme of the present invention, the user self-selects the number of the strip-shaped holes of the fixed plate and the number of the assembled clamping seats according to the radian and the length of the arc tube, the clamping seats can optionally turn round only requiring the loose state of the locking nut after the numbers are determined so as to adapt to different radian point of the arc tube, the locking nut rotates after the clamping is determined so as to perform positioning, and the lifting can be performed through the hanging rings.
