Abstract

The utility model discloses an angle regulating mechanism of cutting saws. A support device for regulating the positions of saw blades is composed of a fixing seat, a rotating shaft, worm gears, a worm and support arms for installing a motor, wherein the end of the rotating shaft is also provided with a rotating positioning device of the support arms. As the two worm gears for connecting the front and the back support arms are respectively arranged on the same rotating shaft, and an intersecting line of the cutting planes of the horizontal saw blade and the vertical saw blade coincides with the axial cord of the rotating shaft, the two saw blades always have a common rotating axial cord when rotate around the axial cord within the angle of-45 DEG to 0 DEG and 0 DEG to +45 DEG. Thus when the angle and the dimension of a tenon need to be changed in the process of use, the worm is rotated to make the worm gears drive the saw blades to rotate to the required angle displayed by a digital display meter and fix the saw blades conveniently. As the motor is connected with the saw blades via a main shaft arranged on a fixing plate of the motor, the axial float caused by the manufacturing errors of the motor can be reduced, and the accuracy and the quality of the cutting angle of a tenoning port can be guaranteed.
