Abstract

The invention discloses a saw. The current saw comprises a saw frame and a saw blade composed by a bow back of the saw and a handle. When there is barrier, or the cutting depth is beyond the length between saw blade and bow back of the saw, the sow can't be used. The said saw comprise saw frame, saw blade and slipping strip. The slipping strip comprises long side and short side, and they form L shape. The long side is connected with saw frame through resetting-mechanism, and the on the short side there is mouth to prevent flexibility. One end of saw blade is connected with saw frame, and the other end of saw blade is free end. The invention has the advantages of reasonable structure, little operating area, wide sphere of application and strong intensity.

Description

technical field [0001] The invention discloses a saw, which is suitable for occasions where the object to be sawed has obstacles and the working surface is small or the sawing depth is deep. Background technique [0002] Existing saws generally include a saw blade and a saw frame for fixing the saw blade. The saw blade is mainly composed of a bow-shaped saw back and a handle. The front and rear ends of the bow-shaped saw back are respectively provided with a hook-shaped member for fixing the saw blade. As disclosed in the international application PCT / FR95 / 00256, the saw frame includes a bow frame, a handle connected to the bow frame, a distal front member arranged at the front end of the saw frame for attaching the saw blade, and a front member arranged at the rear end of the saw frame. It is used to connect the proximal rear member of the saw blade; and as disclosed in Chinese Patent No. 03228624.4, "a quick-loading saw frame" includes a bow saw frame, a pull pin arranged ...
