Abstract

A worktable includes a frame pivotally attached to a housing, a holder pivotally attached to the frame, a saw blade having a spindle rotatably attached to the holder for cutting one or more work pieces, and a guide member attached to the spindle of the saw blade, for engaging with and for guiding the work piece after being cut by the saw blade. A casing is secured to the frame and includes an outlet for coupling to a vacuum device. A follower is pivotally attached to the casing, for adjustably supporting the guide member, to allow the guide member to be adjusted relative to the frame and the housing. A shield may be attached to the guide member, for shielding the saw blade, and may be coupled to a vacuum device.

Claims

1. A worktable comprising:

a housing,

a frame pivotally attached to said housing,

a holder pivotally attached to said frame,

a saw blade including a spindle rotatably attached to said holder, for cutting a work piece, and

a guide member attached to said spindle of said saw blade, for engaging with and for guiding the work piece after being cut by said saw blade.

2. The worktable as claimed in claim 1, wherein said frame includes a casing secured thereto and rotated in concert with said frame relative to said housing, said casing includes a chamber formed therein to receive said saw blade.

3. The worktable as claimed in claim 2, wherein said casing includes at least one passage formed therein to slidably receive said spindle of said saw blade, and for allowing said spindle of said saw blade to be moved relative to said frame and said casing.

4. The worktable as claimed in claim 2, wherein said casing includes an outlet formed therein for coupling to a vacuum device.

5. The worktable as claimed in claim 2 further comprising a follower pivotally attached to said casing, and rotatably attached to said spindle of said saw blade, for supporting said guide member.

6. The worktable as claimed in claim 5, wherein said follower includes a link pivotally coupled thereto and pivotally coupled to said casing, for guiding said follower to move relative to said casing.

7. The worktable as claimed in claim 5, wherein said casing includes a bar attached thereto, and said follower includes at least one finger extended therefrom and slidably engaged with said bar, for guiding said follower to move relative to said casing.

8. The worktable as claimed in claim 5, wherein said follower includes a lock member for locking said guide member to said follower.

9. The worktable as claimed in claim 8, wherein said follower includes a groove formed therein, and said lock member includes at least one projection extended therefrom and slidably engaged in said groove of said follower, for guiding said lock member to slide and to adjust relative to said follower.

10. The worktable as claimed in claim 8, wherein said guide member includes a pathway formed therein, said lock member includes at least one protrusion extended therefrom and slidably engaged in said pathway of said guide member, for guiding said guide member to slide and to adjust relative to said lock member and said follower.

11. The worktable as claimed in claim 10, wherein said lock member includes an anchor member secured thereto and having at least one cavity formed therein, for receiving said at least one protrusion of said lock member, and for preventing said guide member from being rotated relative to said follower.

12. The worktable as claimed in claim 1 further comprising a shield attached to said guide member, for covering and shielding said saw blade.

13. The worktable as claimed in claim 12, wherein said shield includes an outlet hose for coupling to a vacuum device.

14. The worktable as claimed in claim 12, wherein said guide member includes a lock notch formed therein, said shield is pivotally attached to said lock notch of said guide member with a pivot pin.

15. The worktable as claimed in claim 1, wherein said frame includes two side- panels secured thereto, for pivotally attaching said frame to said housing.

16. The worktable as claimed in claim 15, wherein said housing includes two side portions each having a curved sliding member provided thereon, and said side panels of said frame each includes a sliding member provided therein, for slidably engaging with said sliding members of said housing, and for pivotally attaching said frame to said housing.

17. The worktable as claimed in claim 15, wherein one of said side panels includes a sector gear provided thereon, and a handwheel is rotatably attached to said housing with a pivot axle, and a bevel gear attached onto said pivot axle and engaged with said sector gear of said side panel, for adjusting said frame relative to said housing with said handwheel.

18. The worktable as claimed in claim 15, wherein said holder includes a sector gear provided thereon, and a handwheel is rotatably attached to said side panels with a pivot rod, and a bevel gear attached onto said pivot rod and engaged with said sector gear of said holder, for adjusting said holder relative to said frame with said handwheel.
