Rotary locking structure capable of rotating at multiple angles for welding

The invention discloses a rotary locking structure capable of rotating at multiple angles for welding, and relates to the field of welding machining. The rotary locking structure comprises a supporting mechanism, a first-stage gear clamping device and a circuit control box, the top face of one end of the supporting mechanism is fixedly connected with the first-stage gear clamping device, the top face of the other end of the supporting mechanism is fixedly connected with a second-stage gear clamping device, a rotary locking mechanism B is sleeved with the first-stage gear clamping device, and the other end of the rotary locking mechanism B is clamped with a lifting placing box. According to the rotary locking structure capable of rotating at multiple angles for welding, a traditional welding mode is changed, angle rotation and height lifting can be combined, meanwhile, pipelines can be locked, fixed and fused together, and the effect that one machine has multiple purposes can be achieved; and by means of the m
