After turning on the switch of the second motor, the two rollers 5 can move synchronously, pulling the adjustable protection 2 to move outward to close the steel bar processing site. At this time, the winding roller 4 rotates freely under the control of the first motor. After turning off the switch of the second motor, the roller 5 can rotate freely in the opposite direction, and driven by the winding roller 4 and the first motor, the adjustable protection 2 moves inward to open the steel bar processing site.

In addition, the structural strength of the top frame 1 can be improved. By setting the two limiters 8, the rolling displacement of the roller 5 can be limited to prevent the roller 5 from leaving the track 7, thereby ensuring safety.
