On the surface, the top of the outer wall of the bolt is limited and pressed by a nut, and a V-shaped pressing plate is provided, and the bent pipe workpiece is clamped between the V-shaped iron and the V-shaped pressing plate.

Further, a long groove is formed at one end of the fixing plate 1 and the fixing plate 2 away from the vertical joint, and the bottom of the bolt passes through the long groove and is screwed with the nut on the bottom.

Further, a dovetail sliding block is arranged on the connecting end surface of the first fixing plate and the second fixing plate, and a dovetail sliding groove is arranged on the second fixing plate, which is matched with the dovetail sliding block.

Further, two sets of front and rear hexagon socket screws are arranged at the bottom of the second fixing plate corresponding to the dovetail chute.

Further, the nuts and bolts are M16 nuts and M16 bolts respectively.

Compared with the prior art, the beneficial effect of the utility model is that two mutually perpendicular fixed plates 1 and 2 are supported by the four-jaw chuck of an ordinary lathe, and the two ends of the elbow are processed respectively. Install the V-shaped iron on the fixing plate, fit the elbow on the slope of the V-shaped iron, and press the upper part with the nut through the V-shaped pressure plate. The workpiece can be processed by clamping the fixing plate. At the same time, the two fixing plates have long grooves, which can easily adjust the clamping part of the elbow, optimize the processing, reduce the cost and improve the efficiency.
