Disposable tooth adjacent face sheet cutting saw

The invention relates to a disposable tooth adjacent face sheet cutting saw. The adjacent face sheet cutting saw comprises a saw handle, an arc-shaped saw rack and an adjacent face sand bar, wherein the saw handle is fixedly connected to the arc-shaped saw rack; the arc-shaped saw rack is of a flat structure and comprises a saw rack left end, a saw bow and a saw rack right end; both ends of the adjacent face sand bar are connected with the saw rack left and the saw rack right end of the arc-shaped saw rack respectively and fixedly. According to the disposable tooth adjacent face sheet cutting saw with the technical scheme, the arc-shaped saw rack can be used for buffering resistance during cutting of the adjacent face sand bar; as the diameter of the middle part of the adjacent face sand bar is smaller than that of both ends of the adjacent face sand bar, the adjacent face sand bar can enter a gap between adjacent teeth conveniently; a sand face of which both ends are wide and large is beneficial to expansion of tooth gaps and adjustment of tooth form; two types of sheet cutting saws are matched with different sand bars so as to be suitable for sheet cutting of various teeth at different parts, the operation is facilitated greatly and is safe and accurate.
