[0008] By adopting the above scheme, the bidirectional screw is driven to rotate, and the bidirectional screw drives the first slider and the second slider to move in the direction of approaching each other. The first slider and the second slider can drive the two clamping plates to move in the direction of approaching each other, so the two clamping plates can clamp the steel bars together; then the driving part is controlled, and the driving part applies external force to the steel bars, so that the steel bars are bent with the positioning piece as the bending point. With the above arrangement, after the bending position of the steel bars is fixed, the workers no longer need to participate in the bending operation, thereby achieving the effect of improving the safety of the workers.
[0009] Furthermore, arc-shaped grooves are provided on the sides of the two clamping plates that are close to each other and in directions away from each other.
[0010] By adopting the above solution, the steel bar is placed between the two arc-shaped grooves, and the arrangement of the arc-shaped grooves facilitates clamping of the steel bar.

[0018] By adopting the above solution, when the two clamping plates complete clamping the steel bars, the locking groove corresponds exactly to the locking rod, and the elastic member stretches under its own elasticity, pushing the locking rod toward the locking groove, so that the locking rod and the locking groove are plugged into each other. This setting can further lock the relative positions of the two clamping plates, thereby increasing the clamping effect of the two clamping plates on the steel bars.
[0019] Furthermore, a blocking plate is arranged between the locking assembly and the clamping part, and a blocking groove is provided on the upper surface of the operating table. The blocking plate is inserted into the blocking groove and can slide back and forth along the blocking groove; a through hole is provided on the blocking plate corresponding to each locking groove, and when the through hole corresponds to the locking groove, the locking rod can pass through the through hole and be plugged into the locking groove.

When the two clamping plates complete the clamping of the steel bars, the blocking plate is driven to slide along the blocking groove so that the positions of the through hole and the locking groove are relative.
[0021] Furthermore, a toggle rod is fixedly connected to the top wall of the blocking groove, and the toggle rod is used to drive the blocking plate to slide along the blocking groove.
