Background

As shown in taiwan patent No. I637809, the conventional tool changing driving device for a simultaneous operation machine is only suitable for a light simultaneous operation machine, but not for a heavy simultaneous operation machine, because it uses a driving sprocket, a driven sprocket and a chain wound around the driving sprocket and the driven sprocket, and the force borne by the chain is limited, and when the chain is used as a medium for transmitting driving force, the chain can only be used for a small driving force, and when the force borne by the chain is too large, the chain is broken. Moreover, the chain may loosen after a period of use, so that the tightness of the chain needs to be adjusted frequently, which relatively affects the processing efficiency and precision. Particularly, the driving sprocket, the driven sprocket and the chain wound around the driving sprocket and the driven sprocket are used for transmission, and the driving sprocket and the driven sprocket can always rotate in the same direction, so that the cutter beating unit can not be applied to the machine types of cutter beating units which need different directions.
