When the cutting line is accidentally in an unstraightened state or receives other external forces, it contacts an sensing column 304 between the two sensing columns 304. At this time, due to the electricity of the opposite electrodes of the sensing column 304 and the molybdenum wire, a relay signal will be given after the collision, and the first movable block 307 will be driven by the operation of the driving motor to move toward the direction of the sensing column that is not in contact with the sensing column, so as to achieve the operation of re-correcting the cutting line, so that the cutting line is stably wound around the take-up wheel 502, and the stable cutting operation is ensured.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
