Preferably, two adjustable supports are further mounted on the bottom plate, the two adjustable supports are respectively located on the front side and the rear side of the left bending portion of the elbow, and the upper portion of each adjustable support abuts against the side wall of the left bending portion of the elbow.

Compared with the prior art, the utility model discloses following beneficial effect has: this return bend anchor clamps block the lower part of return bend left end through first V-arrangement piece, and inside the round hole that the end of first clamp plate passed the return bend left end got into the return bend, thereby adjust first stud and make first clamp plate press from both sides the left end of tight return bend downwards, in addition, the right-hand member of return bend anchor clamps is equipped with the second V-arrangement piece that can block return bend right-hand member lower part, adjusts second stud and can make the second clamp plate press from both sides the right-hand member of return bend downwards tightly. The utility model provides a return bend anchor clamps simple structure, clamping effect are comparatively stable, the clamping is fast, can effectively improve the machining efficiency of return bend work piece, have very wide application prospect.
