A fixing mechanism for fixing the steel material 7 is installed on the table of the workbench 1, and the fixing mechanism includes a first clamping member, a second clamping member, and a third clamping member. The table of the workbench 1 has movable openings 10 corresponding to the left and right. The first clamping member includes two first clamping plates 3 that are symmetrical on the left and right. The two first clamping plates 3 are horizontally slidably installed at the openings of the corresponding movable openings 10 through the first slide rail 12.

The first driving assembly includes a motor 33 and a lead screw 32 horizontally installed under the table of the workbench 1. The lower ends of the two first clamping plates 3 pass through the movable opening 10 downward and are respectively threadedly sleeved on the positive and negative threads on both sides of the lead screw 32, and one end of the lead screw 32 is connected to the power of the motor 33. When the motor 33 is started to drive the lead screw 32 to rotate, the two first clamping plates 3 sleeved on the positive and negative threads on both sides of the lead screw 32 can approach each other, thereby clamping and fixing the steel material 7 in the left and right directions.
