Rotary joint and worktable using the same

摘要

A rotary joint includes an input member and an output member rotatably sleeved on the input member. The input member defines a through hole extending along a vertical axis of the input member. A plurality of mounting portions circumferentially protrudes from an outer surface of the input member. Each two adjacent of the plurality of mounting portions form a first receiving groove. A plurality of transmission holes is defined in the input member. An opening of each transmission hole away from the end surface of the input member is formed in a sidewall of the first receiving groove. An output member is rotatably sleeved on the input member. Sidewalls of the first receiving groove and an inner wall of the output member cooperative form a channel. An outlet is defined in the inner wall of the output member. The invention also discloses a worktable using the rotary joint.
