Operation Device for Quick and Accurate Control of Working Device of Tenoner

An operation device for controlling a working device adapted to manufacture a tenon and/or a mortise in a workpiece, with the working device movably mounted on a tenoner, with the tenoner including a guiding member mounted thereon and including a plurality of sides each formed with a plurality of protuberances, with the plurality of protuberances disposed in a longitudinal direction of the guiding member, and with the plurality of protuberances collectively defining an undulated edge, comprising:

• a connecting member mounted on and moved with the working device;
• and
• a positioning mechanism mounted on and moved with the connecting member and including a tube mounted on the connecting member and adapted to be fixed at various positions, an elastic member and a shaft retained in a hollow of the tube, with the shaft including an end extended outside of the tube and engaged with the undulated edge of the guiding member, with the elastic member disposed between the tube and the shaft and selectively depressed such that the elastic member enables the shaft to movably engage with a shape of the undulated edge of the guiding member in a quick and accurate manner.
