A large spring is arranged between the guide sleeve and the cover, and a small spring is arranged between the guide sleeve and the sliding shaft. When the wedge is inserted into the saw seam , With the progress of sawing, the saw seam of the steel plate is deformed, the wedge can slide left and right along the sliding hole, and the large and small springs are compressed respectively, which effectively avoids the bending damage of the wedge caused by the deformation of the steel plate saw seam, and prolongs the use of the wedge. During the sawing process, the wedges always keep close contact with the saw seam, and the support effect on the saw seam is good. When the sawing is finished, the wedge leaves the saw seam and retreats upward, and returns to the initial position under the combined action of large and small springs, that is, the position aligned with the saw seam, to ensure that the saw seam can be smoothly inserted when sawing a new steel plate.
