[0011] Furthermore, the X-axis adjustment device comprises a fixing seat and an adjusting screw, the adjusting screw is threadedly connected to the fixing seat, and one end of the adjusting screw abuts against the side wall of the adjusting plate.

[0012] Furthermore, a plurality of lifting screws and clamping screws are provided at both ends of the power head mounting plate connected to the mounting bracket.
