Angle adjusting module

The invention relates to an angle adjusting module. The angle adjusting module is characterized in that clamping pieces of the angle adjusting module are rotationally mounted on second connecting bodies through mounting shafts, rotary adjusting gear parts are assembled on the mounting shafts, angle adjusting pieces are movably mounted on the second connecting bodies in the length directions of thesecond connecting bodies, adjusting rack parts are arranged on the angle adjusting pieces, the adjusting rack parts are in transmission connection with each rotary adjusting gear part assembled on the second connecting bodies, and the angle adjusting pieces are moved to adjust each rotary adjusting gear part to rotate synchronously. The angle adjusting module is used for adjusting the orientationof a clamping opening of a clamping device so as to meet the clamping requirements of spiral blades with different inclination angles; and the angle adjusting module is combined with an adjusting module for adjusting the scre
