Abstract
A device of double saw blades includes a first saw blade, a second saw blade, a driving device and security system. The first saw blade and the second saw blade rotate around a rotation axis oppositely, and respectively include a blade body and a cutting element mounting on a periphery of the blade body. The driving device connects with the first saw blade and the second saw blade, and has a driving diameter. The security system has a security distance provided between the blade bodies. The security system includes two rigidity enhancers. The rigidity enhancers respectively include a saw blade adapter mounting on an outer side of the blade bodies. The saw blade adapters respectively have a predetermined diameter to enhance a rigidity of the blade bodies, so as to reduce deformation thereof when working. The diameters are no more than the driving diameter.
