When, different types of cutter is installed respectively on two or more cutter output shafts 733, starts first motor 721, first motor
721 output shaft band driven input shaft 722 rotates, and input shaft 722 drives bevel gear wheel 723 to rotate, and bevel gear wheel 723 passes through conelet
Gear 732 drives corresponding cutter output shaft 733 to rotate, and to drive cutter to work, realizes processing；Such as to adjust the position of cutter
It sets, electromagnetic clutch 724 is first allowed to detach, then start the second motor 742, the output shaft of the second motor 742 drives worm screw 743 to revolve
Turning, worm screw 743 drives rotary sleeve 746 to rotate by worm gear 744, and rotary sleeve 746 drives rotating seat 731 to rotate, after the completion of adjustment,
Stop the second motor 742, closed electromagnetic clutch 724 when starting first motor 721 can continue that cutter output shaft 733 is allowed to revolve
Turn.The structure of the present invention, simultaneously can be processed workpiece with the cutter on cutter shaft using same power head, therefore, can improve
Processing efficiency and machining accuracy.Rotary sleeve 746 is rotated around fixing axle 745, makes the movement of rotary sleeve 746 more steady.
