Description

technical field [0001] The invention relates to a cutting device, in particular to a manual labor-saving saw. Background technique [0002] Manual saw has become a kind of cutting tool commonly used in people's daily life because of its simple structure and low cost. Ordinary manual saws are mainly composed of saw blades and handles, and the cutting process is realized in the process of pushing and pulling. However, because manual pushing and pulling is not only slow, but also very laborious, the work efficiency is very low during application. Contents of the invention [0003] The technical task of the present invention is to provide a manual labor-saving saw in view of the deficiencies in the above-mentioned prior art. The manual saw has the characteristics of convenient use, labor saving and high work efficiency. [0004] The technical solution adopted by the present invention to solve the technical problem is: a man...
