The worm 224 rotates under the action of the spring 41, and drives the worm gear 226 engaged with the worm gear 224 to rotate, and drives the rotating rod 227 and the half gear 228 to rotate, thereby causing the pinion 46 to rotate under the support of the long rod 43 in the through hole inside the T-shaped support seat 229, and then performs the cutting operation on the workpiece 35 during the movement of the cutting head 45. In addition, when the half gear 228 rotates to disengage from the pinion 46, the cutting head 45 is driven to move in the opposite direction under the action of the spring 41, and then drives the cutting head 45 to perform a swing cutting operation during mobile cutting.
