When the connecting plate 303 moves downward, the buffer spring 8 After the first pressure sensor 307 contacts the first pressure sensor 307, the first pressure sensor 307 will send an electrical signal to the rotating motor 311, the hydraulic rod 302 and the rotating motor 304 through the wire again, so that the rotating motor 311 rotates again, and the rotating motor 304 stops running and the hydraulic rod 302 returns. At this time, the rotation of the rotating roller 310 can drive the remaining steel bars to re-enter between the two support frames 301 and repeat the above operation, so that the construction steel bar cutting machine can complete the feeding without the staff manually feeding the steel bars into the cutting machine continuously, so that the cutting machine has an automatic feeding function, which can be more The entire steel bar can be cut conveniently and quickly in sections, which effectively increases the use efficiency of the construction steel bar cutting machine and the convenience of steel bar cutting. In addition, through the threaded connection relationship between the screw 314 and the fixed frame 308, the adjustment frame 309 and the rotating roller 310 can be adjusted up and down by rotating the screw 314 in conjunction with the compression spring 312, and then the telescopic plate 316 is used to telescope inside the adjustment cylinder 315 to cooperate with the positioning of the positioning pin 12 and the positioning hole 11.
