Cylinder rod and rotating shaft connecting structure of sewing machine pressing rotating mechanism

The utility model discloses an air cylinder rod and rotating shaft connecting structure of a pressing and rotating mechanism of a sewing machine. Wherein the first connecting shaft and the second connecting shaft are installed on the connecting block assembly in a rotating mode and used for being connected with an air cylinder rod and a rotating shaft respectively, and the head of the first connecting shaft and the head of the second connecting shaft abut against each other to form a pressing contact and rotating separation structure. The connecting block assembly is used for framing the two connecting shafts which are in axial pressing contact and separated in radial rotation, and the two connecting shafts are used for being connected with the air cylinder rod and the rotating shaft respectively. When in use, the cylinder rod anti-rotation cylinder is combined to transmit axial telescopic motion and force and realize rotary separation of the rotary shaft and the cylinder rod during circumferential rotary mot
