Wood-turning lathe

A wood-turning lathe including a bed, a headstock, a tail-stock, and a tool rest between said headstock and said tail-stock, said headstock, said tail-stock and said tool rest being mounted on said bed, wherein said headstock comprises:

• a headstock body having a left side;
• a driven shaft journalled to said headstock body, and having an output end extending outwardly from said left side of said headstock body;
• a drive shaft journalled to said headstock body, and vertically spaced apart from and extending parallel to said driven shaft, said drive shaft having a coupling end extending outwardly from said left side of said headstock body;
• first and second pulley units mounted respectively on said coupling end of said drive shaft and said output end of said driven shaft, one of said first and second pulley units having a side surface formed with a plurality of circumferentially and angularly spaced retaining holes;
• a non-elastic belt interconnecting said first and second pulley units such that rotation of said drive shaft results in synchronous rotation of said first and second pulley units;
• and
• an angular adjusting device including
• a cam member mounted movably on said headstock body, defining a cam face, and movable between a locking position and an unlocking position, and
• a cam follower in the form of a spring-biased pin mounted on said headstock body and disposed between said side surface of said one of said first and second pulley units and said cam member, said cam follower being urged to slidably contact said cam face such that when said cam member moves to said locking position, said pin is pushed by said cam face against biasing force thereof so as to engage said pin with a selected one of said retaining holes in said one of said first and second pulley units, thereby immobilizing said first and second pulley units, and such that when said cam member moves to said non-locking position, said pin disengages from said selected one of said retaining holes in said one of said first and second pulley units, thereby permitting synchronous rotation of said first and second pulley units.
