Elbow clamp for lathe machining

The elbow clamp for lathe machining comprises a transverse support and a longitudinal support, and the top of the transverse support is fixedly connected with a transverse fixing assembly. According to the elbow clamp for lathe machining, the transverse support, the longitudinal support, the transverse fixing assembly, the rotating assembly, the limiting assembly, the movable groove, the supporting block and the pointer are matched with one another, the fixing bolt is screwed, an elbow is clamped in the longitudinal direction through the clamping plate, the clamping bolt is screwed, and the elbow can be fixed. The transverse part of an elbow is clamped through the transverse clamping plate, the elbow is clamped in the transverse direction and the longitudinal direction, limiting of an elbow pipe is completed, the position of the containing base is adjusted so that corresponding adjustment can be conducted according to different machining positions, a rotating handle is rotated, a rotating disc is driven to ro
