Novel hydraulic support connector

The utility model relates to a novel hydraulic support connector which comprises a connecting shaft, a connecting sleeve and a fixing assembly, the connecting shaft comprises a lug plate end and a spherical surface end, a through hole is formed in the lug plate end, and a pin shaft penetrates through the through hole and then is connected with a lug plate of a scraper conveyor; the spherical end is of a spherical structure, the connecting sleeve is composed of two half-and-half convex structures, the lower ends of the convex structures bulge outwards, a spherical inner cavity matched with the spherical end in size is formed in the middle of each convex structure, and the spherical end is installed in the spherical inner cavity through the fixing assembly to be fixed. The hydraulic support is ingenious in design and simple in structure, a lug plate pin shaft connection structure of a traditional connector is changed into spherical surface connection, the hydraulic support can rotate by a large amplitude and de
