[0029] It should be noted that the side wall of the slider 4 abuts against the inner wall of the slide groove 3 , so that the slider 4 does not rotate together with the bidirectional lead screw 9 .

[0030] A plurality of first springs 11 are fixedly connected to the inner wall of the groove 7, and the other ends of the plurality of first springs 11 are fixedly connected to the side wall of the clamping plate 8. When the clamping plate 8 clamps the elbow, the first springs 11 will be compressed first to provide a buffer for the clamping plate 8, thereby preventing the elbow surface from being suddenly stressed, thereby causing the elbow surface to be deformed by clamping.

[0031] A fixing mechanism is installed on the processing table 2, and the fixing mechanism includes a fixing column 12 fixedly connected to the upper end of the processing table 2, a plurality of slides 13 are fixedly connected to the side wall of the fixing column 12, and the plurality of slides 13 are symmetrically arranged along the axis of the fixing column 12, and the inner walls of the plurality of slides 13 are slidably connected to slide plugs 14, and the side walls of the slide plugs 14 are fixedly connected to a cross bar 15, and the other end of the cross bar 15 penetrates the side wall of the slide 13 and is fixedly connected to a clamping block 16, and the inner wall of the slide 13 is fixedly connected to a second spring 17, and the other end of the second spring 17 is fixedly connected to the side wall of the slide plug 14.
