9, can realize that the guide that can give connecting rod 85 through arc 10 when connecting rod 85 passes through the corner of Z type groove 84 can be given connecting rod 85 one strand of rotation The guiding force is applied to greatly reduce the steering difficulty of the connecting rod 85, and simultaneously the jerking feeling generated when the connecting rod 85 steers can be greatly reduced, so that the cutting process is smoother, the connecting rod 85 is prevented from being deformed due to the impact of corners when sliding in the Z-shaped groove 84 for a long time, so that the two sides of the cutting knife 86 are not in the same horizontal plane, the cutting efficiency and the cutting quality are affected, when the arc-shaped plate 10 is extruded, the reset plate 13 at the inner side is also extruded, namely, the cavity between the reset plates 13 is compressed under the extrusion force, so that the inner air pressure is conveyed into the wall of the guide wheel 12 by the arc-shaped plate 10 to force the outer wall of the guide wheel 12 to expand outwards, namely, when the connecting rod 85 contacts with the guide wheel 12 through the arc-shaped plate 10, the

phenomenon that the pressure between the cutting knife 86 and a wooden plate is small due to the fact that the sliding speed of the connecting rod 85 in the Z-shaped groove 84 is too high is avoided, cutting efficiency is affected, scratches of the cut surface of the wooden plate are prone to being generated in different degrees, meanwhile when the connecting rod 85 moves in the Z-shaped groove 84 and is in contact with the guide wheel 12, the outer wall of the guide wheel 12 is set to be a rubber wall, friction force between the guide wheel 12 and the connecting rod 85 is greatly increased, namely relative rotation movement rather than relative sliding between the guide wheel 12 and the connecting rod 85 is guaranteed, the phenomenon that the outer wall of the guide wheel 12 is thinned due to friction of the connecting rod 85, service life is shortened is avoided, meanwhile, due to the fact that the hinged plate 14 is arranged on the outer side of the guide wheel 12, the scraping plate 15 is installed on the inner wall of the hinged plate 14, when the guide wheel 12 rotates, dust remaining on the outer surface of the guide wheel 12 can be scraped through the scraping plate 15, and high friction force is kept between the guide wheel 12 and the connecting rod 85 all the time, the protection of the guide wheels 12 is further improved.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
