[0027] like Figure 4 As shown, the utility model provides a technical solution for a rotary joint to prevent loosening and falling off: the limiting mechanism 6 includes a fixing ring 61, and connecting grooves 610 are respectively provided on the left and right sides of the outer wall of the fixing ring 61, and the inner walls of the two connecting grooves 610 are fixedly connected with reset springs 63, and the two reset springs 63 are fixedly connected with a fixing block 62 on the side away from the connector 4.
