Table saw

A table saw comprising:

• a mounting frame having a working table and an elongated slot which is formed in said working table and which extends in a longitudinal direction;
• a motor having an output shaft to deliver a driving force, said motor being secured to said mounting frame, said output shaft defining a first axis and extending in a first direction transverse to the longitudinal direction;
• a blade shaft defining a second axis parallel to the first axis, and turnable about the first axis between first and second positions respectively proximate and distal to said working table, said blade shaft including right and left ends which are disposed opposite to each other in the first direction, and a middle portion which is disposed between said right and left ends;
• a blade mounted on said right end of said blade shaft so as to be rotated therewith about the second axis, and extendable into said elongated slot in a second direction transverse to both the first and longitudinal directions;
• a drive transmission member disposed to transmit the driving force of said output shaft of said motor to said middle portion of said blade shaft in either one of the first and second positions so as to drive said blade shaft to rotate said blade when said motor is actuated;
• a height adjusting member including a driven portion disposed to be displaceable relative to said mounting frame in the second direction between higher and lower positions corresponding to the first and second positions respectively, and a shifting portion disposed to surround said middle portion of said blade shaft to move said middle portion to turn between the first and second positions;
• an actuator member having an actuating end disposed to move said driven portion to displace between the higher and lower positions, and an externally operated end disposed outwardly of said mounting frame so as to be operated externally to actuate movement of said actuating end;
• a shaving collecting member disposed in the vicinity of said blade to collect wood shavings, said shaving collecting member having an outlet port;
• an elongated hollow member defining a duct therethrough, and having a first tubular end connected to said shaving collecting member such that said duct is communicated with said outlet port, and a second tubular end;
• and
• a blowing member including
• a casing secured to said height adjusting member, and having proximate and distal walls which are spaced apart from each other in the first direction and respectively proximate and distal to said right end of said blade shaft to confine an accommodating chamber, and a discharge port which is disposed between said proximate and distal walls and which extends radial to the second axis, said proximate wall being mounted on said left end of said blade shaft to permit rotation of said left end relative thereto, said distal wall being provided with an inlet port which is connected to and which is communicated with said second tubular end of said hollow member, and
• an impeller received in said accommodating chamber, and mounted to be driven by said left end of said blade shaft to rotate about the second axis so as to draw wood shavings from said shaving collecting member to said accommodating chamber via said duct and out of said discharge port.
