The support component includes a support rod and a fixed block. A plurality of first threaded holes are opened at the top of the support rod. The center position of the bottom of the support rod is welded and fixed to the top of the fixed block. Two trapezoidal rods are fixedly connected to the bottom of the support rod, and the bottom ends of the two trapezoidal rods are respectively attached to the two side walls of the fixed block. The correction component includes two sliders and a correction rod. Second threaded holes are opened at the tops of the two sliders, bolts are installed in the two second threaded holes, first rectangular grooves are opened on the side walls of the two sliders, the bottoms of the two sliders are respectively fixedly connected to one ends of the two correction rods, and a correction block is welded and fixed to the other ends of the two correction rods.
