At this time, the pushing part is in a horizontal state, and then the user can adjust the shape of the bracket according to the drilling position of the first mounting hole; if the user drills the first mounting hole crookedly when boring, the shape of the bracket can be adjusted to the center of the boring hole in the subsequent process, so as to improve the accuracy of the processing bracket and reduce errors.

[0009] By adopting the above technical solution, the user operates the second clamp to clamp the bracket, and then uses the pushing part to drive the second clamp and the bracket to slide along the length direction of the conveyor table. When the bracket moves to the jig tooling and the clamp hole tooling, the user operates the pushing part to move away from the bracket, and then the user operates the second clamp to rotate, and then the user operates the pushing part to push the side wall of the bracket, and then push the bracket into the placement hole, and then the user can process the bracket. The pushing part can push different positions of the bracket to drive the bracket to move.
