It should be noted that, in the following description of the present embodiment, reference is made to fig. 3 for clockwise and counterclockwise directions.
The pressing cantilever 4 is further provided with two limiting posts 43 for limiting the rotation stroke of the operating rod 42, preferably, in this embodiment, two limiting posts 43 are provided, one of the limiting posts 43 is used for limiting the counterclockwise rotation stroke of the operating rod 42 to ensure that the operating rod 42 does not continue to rotate after the connection position of the spring 22 and the operating rod 42 is located below the pressing cantilever 4, and the other limiting post 43 is used for limiting the clockwise rotation stroke of the operating rod 42 to ensure that the connection position of the spring 22 and the operating rod 42 does not continue to move after moving from below the pressing cantilever 4 to the side edge of the pressing cantilever 4. Thus, when the handle of the operating rod 42 is rotated so that the connecting position of the spring 22 and the operating rod 42 is located below the pressing cantilever 4, the elastic force of the spring 22 presses the pressing cantilever 4 upwards through the operating rod 42, so that the distance between the tension wheel 41 and the driving wheel 21 is increased, and the abrasive belt 7 is tensioned; during sanding of the sanding belt, if the tightness of sanding belt 7 changes, the position of tensioning wheel 41 will also change under the action of the elastic force of spring 22, so as to realize automatic adjustment of tightness of sanding belt 7. When the connecting position of the spring 22 and the operating rod 42 is moved away from the lower portion of the pressing cantilever 4 by using the handle of the operating rod 42, the elastic force direction of the spring 22 changes under the lever action of the operating rod 42, so that the pressing cantilever 4 swings downwards under the dual actions of gravity or gravity and elastic force, the distance between the tension wheel 41 and the driving wheel 21 becomes smaller, the abrasive belt 7 is loosened, the operation of detaching or replacing the abrasive belt 7 can be performed at the moment, and the abrasive belt 7 is more convenient to detach and detach.
As an improvement of the present invention, a rubber-coated grinding wheel can be formed by sleeving a layer of rubber on the outer layer of the first driven wheel 51, which is different from sliding friction between the flat grinding plate 53 and the abrasive belt 7, rolling friction between the rubber-coated grinding wheel and the abrasive belt 7, and the rubber has a damping effect, so that the rubber-coated grinding wheel has a good grinding effect and a high grinding efficiency.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
