The direction of the lateral movement is consistent with the length direction of the component, so that the drilling structure and the tapping structure are both close to the component, making it easy for the drilling structure of the hot-melt drilling to come into contact with the operator. Therefore, the present scheme provides a drilling and tapping machine, which can swing the hot-melt drilling structure away from the component after use by changing the lateral movement position of the drilling structure and the tapping structure to an arc-shaped swing position change method, thereby reducing the safety hazards caused when operating the component.
