[0015] In order to make the electrical installation rail 5 maintain a stable position and posture during the cutting process, and to have sufficient pressing force to prevent the electrical installation rail 5 from having too large a rounded corner, large cross-section burrs, and uneven cross-section during cutting, so as to improve the punching accuracy of the electrical installation rail 5 and reduce burrs, a rail support mechanism can also be provided on the cutting seat 2, and the rail support mechanism includes a support block 9, which is located in the cutting seat 2 and at the front side of the slot 21.
