Quick descending mechanism of cutting equipment

The utility model provides a fast descending mechanism of cutting equipment, which comprises a base, a support, a cross beam, a cutting mechanism and a lifting mechanism, the support is mounted on the base, the cross beam is mounted on the support in a vertically movable manner, the cutting mechanism is mounted on the cross beam, a cutting part is arranged on the cutting mechanism, and the lifting mechanism is mounted between the base and the cross beam to drive the cross beam to ascend and descend. A fast descending rod capable of moving up and down is installed on the cross beam, the bottom of the fast descending rod is lower than the bottom of the cutting part when the cross beam does not make contact with an external component, and a position sensor used for sensing the position of the fast descending rod is arranged on the cross beam. Through the arrangement of the quick descending rod, when cutting is started, the cross beam can quickly descend, after the bottom of the quick descending rod makes contact
