A feed opening 97 is opened on both sides of the top of the workbench 1, and a vertical plate 92 is fixedly connected to the top of the workbench 1 and on both sides of the feed opening 97. A first traction rod 93 is rotatably connected between the two vertical plates 92 through a bearing, and a first traction rod 93 is rotatably connected between the two vertical plates 92 and in front of the first traction rod 93.
