The cross-sectional shape of the adjustment groove matches the shape and size of the longitudinal sectional view of one end of the eccentric slider, so that the end of the eccentric slider can move in the adjustment groove to adjust the lateral position between the eccentric slider and the rocker arm rotating head, thereby adjusting the swing amplitude of the connecting rod and ultimately adjusting the swing amplitude of the sanding belt. The end connecting the eccentric shaft and the eccentric slider is provided with a locking nut. The adjustment groove and the eccentric slider are fixed on the lateral surface between the rocker arm rotating head by the locking nut.

2. The five-axis sanding woodworking machine head according to claim 1, characterized in that: The polishing mechanism includes a cylinder, a mounting base, a polishing drive mechanism, a polishing head, a polishing rotation mechanism, a polishing mechanism mounting base, a polishing connecting frame, a slider, a slide rail, a rotary motor, and a polishing unit. The cylinder is mounted on the bracket via the mounting base, and its output end is connected to the polishing mechanism mounting base to drive the polishing drive mechanism to move downward and outward. The lower end of the polishing drive mechanism is connected to the polishing head, and the lower end of the polishing drive mechanism is connected to the polishing rotation mechanism at the position corresponding to the polishing head. The polishing rotation mechanism is connected to the polishing mechanism mounting base via the polishing connecting frame. The output shaft of the rotary motor passes through the polishing rotation mechanism and connects to the polishing drive mechanism. One end of the polishing connecting frame is mounted on the outer surface of the polishing slide and the upper polishing slider. The inner surfaces of the polishing slide and the upper polishing slider are connected to the polishing lifting slide rail, which is connected to the vertical plate. The other end of the polishing connecting frame is mounted on the slide rail via the slider, and the slide rail is mounted on the polishing mechanism mounting base.

3. The five-axis sanding woodworking machine head according to claim 2, characterized in that: The polishing drive mechanism includes a housing, a pair of meshing gears, a polishing connector, a connecting shaft, a polishing drive mechanism box, a connecting plate, and a polishing motor. The housing contains a pair of meshing gears, one of which is connected to the output end of the polishing motor, and the other is connected to the polishing connector. The other end of the polishing connector is connected to the connecting shaft, and the other end of the connecting shaft is connected to the polishing head. The polishing connector, the connecting shaft, and the polishing motor are installed inside the polishing drive mechanism box. The polishing motor is installed parallel to the connecting shaft, achieving a compact structure for the polishing drive mechanism. The connecting plate is located at the lower part of the polishing drive mechanism and is used to connect to the polishing rotation mechanism.

4. The five-axis sanding woodworking machine head according to claim 3, characterized in that: The polishing mechanism mounting base is provided with positioning blocks at both the upper and lower ends to limit the maximum vertical stroke of the polishing drive mechanism.
