A table saw comprises a circular saw blade suspended in an elongated slot of a worktable and adapted to cut a workpiece, a rib fence adapted to stop the workpiece on the worktable for cutting, a transverse bar fastened to two parallel sliding rods and moved with the sliding rods relative to the worktable to adjust the pitch between the circular saw blade and the rib fence, a connecting member adapted to connect the rib fence to the transverse bar for enabling the rib fence to be moved with the transverse bar on the worktable in direction perpendicular to the slot, the rib fence being connectable to the transverse rib fence and movable on the transverse bar in direction parallel to the slot after disconnection of the connecting member from the rib fence and the transverse bar.

1. A table saw comprising: a base; a worktable fixedly supported on said base, said worktable having an elongated slot; a circular saw blade pivoted in said base and partially projecting out of said slot; a motor mounted inside said base and adapted to rotate said circular saw blade; two sliding rods arranged in parallel at a bottom side of said worktable and moved in and out of one side of said worktable in direction perpendicular to said elongated slot; a transverse bar fixedly fastened to said sliding rods at one end and disposed in parallel to said elongated slot, said transverse bar having a coupling portion; a rib fence provided with a flat bottom sidewall, a stop face disposed at one lateral side thereof and adapted to stop a workpiece to be cut in position for cutting, and a coupling portion which is able to connect to the coupling portion of said transverse bar; and a connecting member having two opposite sides connected detachably and respectively to said rib fence and said transverse bar, thereby enabling said rib fence to be moved with said transverse bar and said sliding rods on said worktable when said connecting member is connected to said rib fence and said transverse bar, and said coupling portion of said rib fence being connected directly to said coupling portion of said transverse bar when said connecting member is detached from said rib fence and said transverse bar. 2. The table saw as claimed in claim 1 wherein the coupling portion of said transverse bar is a longitudinal rib extended along one long side thereof, and the coupling portion of said rib fence is a coupling groove longitudinally extended along one long side thereof fitting the longitudinal rib of said transverse bar for enabling said rib fence to be longitudinally slidably coupled to said transverse bar and extended out of one of two distal ends of said transverse bar. 3. The table saw as claimed in claim 2 wherein said transverse bar comprises at least one screw hole and at least one bolt respectively threaded into said at least one screw hole, and said rib fence comprises at least one through hole adapted to receive the at least one bolt of said transverse bar for enabling said rib fence to be secured to said transverse bar in position. 4. The table saw as claimed in claim 1 wherein said worktable comprises at least two support members adapted to support said sliding rods respectively and to guide movement of said sliding rods relative to said worktable, said two support members each comprising at least one screw hole and at least one holding down screw respectively threaded into the at least one screw hole of said support member and adapted to stop against said sliding rod. 5. The table saw as claimed in claim 1 wherein said rib fence comprises at least one screw hole disposed in one side thereof, and said connecting member comprises an upwardly protruded coupling portion disposed at one side thereof and at least one bolt mounted in said upwardly protruded coupling portion for threading into the at least one screw hole of said rib fence to secure said rib fence to said upwardly protruded coupling portion of said connecting member.
