This is achieved by turning the screw 7, which in turn moves the mounting frame 8 along the width of the second frame 2. Thus, the mounting rack 8 drives the shaft sleeve 19 to move, so as to drive the second cutter to slide along the first rotating shaft 5, and meanwhile, the shaft sleeve 19 keeps the rotation restriction on the second cutter, so that when the second cutter rotates, the PC component can be grooved, and the position adjustment of the second cutter is realized in this way. Meanwhile, the sliding table can be driven to move by the movement of the mounting frame 8, and the grouting mechanism is driven to move. The arrangement is significant in that the position of the grouting mechanism can be adjusted while the second cutter is adjusted, so that the grouting mechanism and the second cutter are kept aligned in the slotting, and the position of the grouting mechanism does not need to be adjusted again.
