[0017] Furthermore, the front-to-back moving mechanism 30 includes front and rear fixed plates 32 fixed to the middle of the top surface of the top plate of the frame 10, and the two ends of the moving screw 33 extending forward and backward are movably connected to the two fixed plates 32 through bearings. A moving motor 34 is fixed to the outer wall surface of one of the fixed plates 32, and the output shaft of the moving motor 34 is a spline shaft, which is inserted into the spline hole at one end of the moving screw 33 and drives the moving screw 33 to rotate, and the moving block 31 is screwed on the moving screw 33.

[0018] A rear support frame is fixed at the rear of the frame 10, a driving motor is fixed on the rear support frame, a rotating shaft is fixed through a plurality of bearing seats, the rear end of the rotating shaft is connected to the output shaft of the driving motor through a coupling, a processing tool is fixed at the front end of the rotating shaft, and the processing tool is located above the rear of the top plate of the frame 10, which corresponds to the wooden stick 100 to be processed installed on the horizontal plate 20.
