ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a miter saw wherein the angle of the handle connected to the circular saw assembly is adjustable and the bench of the miter saw can be pivoted and positioned at desired angle.
BACKGROUND OF THE INVENTION
A conventional miter saw is shown in FIG.
8
and generally includes a base
60
with a disk
65
connected thereon and scale marks are marked on the disk
65
. A circular bench
62
is pivotally supported on the disk
65
and a handle
631
extends from the bench
62
. A position device
63
is connected to the handle
631
and has a position member
632
which is engaged with one of notches
651
defined in an underside of the disk
65
so that the bench
62
can be pivoted and positioned at desired angle. A connection member
64
is connected to the bench
62
so that the circular saw assembly
70
is pivotally connected to the connection member
64
. The circular saw assembly
70
has a blade
74
which is driven by a motor
71
and an arm
72
is connected to a shaft of the blade
74
. A handle
73
is connected to the arm
72
. A fence
61
is located on the bench
62
so that an object to be cut is guided on the fence
61
. The bench
62
can only be positioned at certain angles where notches
651
are available and it is difficult to set the bench
62
at an angle where no notch
651
is available. The user has to hold the handle
631
firmly to maintain the position of the bench
62
and lower the blade
74
to check the object will be cut at desired position. Besides, the handle
73
is fixed so that it cannot be satisfied by different users.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a miter saw which has a handle that is rotated and positioned at a desired angle so as to meet different users' needs.
Another object of the present invention is to provide a miter saw which has a position member connected to the angle position device, wherein the position member is pushed by operating a lever to contact against a periphery of the scale disk to position the scale disk.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
