Referring to
A saw machine 10 has a wheel in the upper side and a wheel in the down side (not shows in FIGS.). A band saw puts around those two wheels. A motor (not shows in FIGS.) mounts inside the saw machine for driving the wheels. A bench 12 has a through-hole 13 thereon for passing through the band saw. There are two adjust devices on the button side of the bench. In this embodiment of present invention, the adjust devices are two arc portions 21 and two arc guiders 23. The arc portions 21 protruding from the bench 12 and each of the arc portions has a trough 22 along the long axis of the arc portion. The arc guiders 23 with a slide hole 24 bend upward and extend from the saw machine. The bench 12 sets on these tow arc guiders 23 and a bolt pass through each corresponding slide hole and trough to fix the bench. The characters of present invention are:
The bench has an observing window 30 thereon and beside the through-hole 13.
An arc gear row 40 that sets beside the arc guider 23 bends upward and extends from the saw machine.
A scale wheel 50 pivots at the button side of the bench 12 and beside the arc portion 21. There are scales 51 around the surface of the scale wheel 50. The user can observe the scale from the observing window. There is a gear wheel 52 beside the scale wheel and gears with the arc gear row 40.
As aforesaid structures disclosed, the user need to release those two adjusting devices 20 and slid the bench 12 to the desired angle when user wants to adjust the angle of inclination. In this embodiment of present invention, user needs to release those two bolts 25 and slid the bench 12 to the desired angle. By the way, the bench can slid along the curve of the arc guider 23. Then, the bench 12 can be fixed by those two bolts in the operation angle. At the same time, the gear wheel 52 will gear with the arc gear row 40 and force the scale wheel 50 to rotate. The user can observe the scale 51 of the scale wheel from the observing window 30 directly. In this operation method, user can slide the bench to a desired angle easily without bending down the body and the angle of inclination of the bench will be more accuracy than prior art.
