[0033] As a further technical solution, the anti-deformation rod 7 is arranged obliquely along the taper of the extended cantilever, including a left anti-deformation rod 71, a right anti-deformation rod 72, and an upper anti-deformation rod 73; an anti-deformation design of the rod is added, and a rod is added to the upper side, left side and right side of the extended cantilever respectively, to solve the problem of the self-weight sagging of the extended cantilever and the left and right swinging tendency during processing affecting the processing accuracy of the equipment, and to improve the rigidity and stability of the equipment.
