ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device, and more particularly to a device for supporting a saw.
2. Description of the Prior Art
Typical hand saws are used for sawing wood workpieces or the like manually. No support devices may be used for supporting the hand saws and for allowing the hand saws to saw the workpieces.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional hand saws.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a device for supporting a saw and for allowing the saw to be operated effectively and accurately.
In accordance with one aspect of the invention, there is provided a device for supporting a saw, the device comprising a) a board including at least post extending upward, b) the saw including a longitudinal rod, and c) at least one frame slidably engaged on the post for allowing the frame to move up and down along the post, the frame includes at least one sleeve for slidably engaging with the longitudinal rod and for allowing the saw to be slided relative to the frame and the post.
The frame includes a ring slidably engaging with the post for allowing the frame to move up and down along the post.
The board is rotatably secured to a base at a pivot shaft and includes an angular graduation for indicating an angular position of the board relative to the base, and fastening device for fastening the board to the base. The board includes a curved slot, the fastening device includes a fastener slidably engaged in the curved slot and engaged through the base for securing the board to the base. At least one support is secured on the base for supporting a workpiece, the support includes an upper surface having at least one bulge for engaging with the workpiece and includes a panel extended upward. At least one clamping device is secured to the support for clamping the workpiece. The clamping device includes a bracket, a first bolt threaded through the bracket and threaded to the support, a second bolt threaded through the bracket for engaging with the workpiece.
A work table is further provided for securing the board. The work table includes a plate secured on top, the board is rotatably secured on the plate at a pivot shaft. The plate includes an arrow provided on top, the board includes a window for viewing the arrow. The board includes a cavity. A fastening device is provided for fastening the board to the plate and includes a bolt slidably engaged in the plate, and a spring biasing the bolt to engage with the cavity of the board and for securing the board to the plate. The fastening device includes a tube secured in the plate, the tube includes a bottom portion having a recess, a pin is engaged through the bolt for engaging with the recess and the bottom portion of the tube, the spring biasing means is engaged between the bolt and the tube for biasing the bolt to engage with the cavity of the board.
