ABSTRACT:
An operation device includes a connecting member mounted on and moved with a working device of a tenoner. A positioning mechanism is mounted on and moved with the connecting member and includes 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. The shaft includes an end extended outside of the tube and a roller mounted on the end and engaged with a guiding member. The elastic member is disposed between the tube and the shaft and selectively depressed such that the elastic member enables the shaft to movably engage with an undulated edge of the guiding member in a quick and accurate manner.
