Spend chi.
By using above-mentioned technical proposal, the setting of graduated scale facilitates staff directly to compare, with find accurately away from
From, it is time saving and energy saving, improve operating efficiency.
It is of the present utility model to be further arranged to：The upper and lower ends of the bands for band are covered with protective cover and lower anti-respectively
Shield.
By using above-mentioned technical proposal, the setting of upper protective cover and low protection cover, it is to avoid staff connects with bands for band
Touch, prevent the injury of staff, strengthen safety precautions.
It is of the present utility model to be further arranged to：The upper protective cover is provided with the upper pressure for being used for abutting the bands for band
Wheel, the low protection cover is provided with the lower pressure wheel for being used for abutting the bands for band.
By using above-mentioned technical proposal, the setting of upper pressure wheel and lower pressure wheel makes bands for band keep vertical, reduces elastic shape
Become, improve cutting accuracy.
In summary, the utility model has the advantages that：By sliding the locating rod set and keeper, first
By sliding locating rod, to realize the adaptation to different cut lengths, then with keeper stationary positioned bar, by impeller middle spindle
Borehole jack is set on the securing lever, a cutting center of circle is provided for impeller, as long as rotary blade can be achieved with to the accurate of impeller outer edge
Cutting, improves operating efficiency, and avoids the impeller that processing is formed dynamic balancing when rotating from lacking of proper care, and reduces the mill of axle and bearing
Damage, increase service life；By setting graduated scale, staff is facilitated directly to compare, to find accurate distance, time saving province
Power, improves operating efficiency.
