A worktable comprising:
- a base having a top wall;
- at least one first rail fixedly mounted on the top wall of said base, said at least one first rail each having a guide groove, a first stop and a second stop;
- at least one guide rod respectively received in the guide groove of each of said at least one first rail and alternatively movable in a first direction and a second direction reversed to the first direction, said at least one guide rod each having a first end and a second end;
- a first end strip fixedly fastened to the first end of each of said at least one guide rod for stopping said at least one guide rod from movement in said first direction when said first end strip touched the first stop of each of said at least one first rail;
- a second end strip fixedly fastened to the second end of each of said at least one guide rod for stopping said at least one guide rod from movement in said second direction when said second end strip touched the second stop of each of said at least one first rail;
- a sliding plate slidably supported on said at least one guide rod, said sliding plate having a bottom wall;
- and
- at least one second rail fixedly mounted on the bottom wall of said sliding plate, said at least one second rail having a guide groove, which receives one of said at least one guide rod, a first push portion, which enables said at least one guide rod to be moved in said first direction when touching said second end strip, and a second push portion, which enables said at least one guide rod to be moved in said second direction when touching said first end strip.
