The upper end of the fixing frame 33 is fixedly connected to the cylinder 34. A shift plate 35 is provided at the piston rod position of the cylinder 34. When the cylinder 34 works, its piston rod extends to drive the moving plate 35 to move, so that the wood floor blank to be polished at the upper end of the transmission structure 32 is clamped in the middle of the front and back. A lead screw 41 is provided in the groove of the sliding groove 4, and the lead screw 41 converts rotational power into linear power. A connecting block 42 is provided on the outer surface of the lead screw 41.
