ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a table saw, and more particularly to a clamping apparatus for clamping a workpiece-blocking plate of a table saw when the plate is not in use.
2. Description of the Related Art
Referring to
FIG. 1
, a conventional table saw is shown to include a machine base
10
, a table
11
that is fixed on the base
10
, and a workpiece-blocking plate
12
that is disposed movably on the table
11
for abutment of a wooden workpiece (not shown) to be cut. A mounting member
13
is attached to a side of the base
10
, and is formed with a positioning groove
14
. When it is desired to transport or store the table saw, the plate
12
is removed from the table
11
, and is subsequently put into the positioning groove
14
in the mounting member
13
. However, the plate
12
may drop from the mounting member
13
when the table saw is moved.
SUMMARY OF THE INVENTION
The object of this invention is to provide a clamping apparatus for clamping a workpiece-blocking plate of a table saw when the plate is not in use.
According to this invention, a clamping apparatus for clamping a workpiece-blocking plate of a table saw includes a mounting member attached to a machine base, and a retaining plate mounted pivotally on the mounting member. The retaining plate has an L-shaped plate portion that supports the workpiece-blocking plate thereon and that is biased to press the workpiece-blocking plate against the mounting member. When the workpiece-blocking plate is removed from the apparatus, the retaining plate can be turned to a storage position, where the retaining plate is disposed within a notch in the mounting member and where the L-shaped plate portion is disposed within an L-shaped notch portion of the notch.
