Pass through above-mentioned technical proposal, because the second compression plate surface is plane, this body side surface of fire grate is arc surface, when second
When pressure strip is pressed on arc surface, two faces can not be bonded completely, can so influence locating effect, be bonded on the second pressure strip
The one side of fire grate body is provided with the arc groove being engaged, and the arc surface and the second pressure strip that can make fire grate body coordinate, so as to
Compression effect is improved, so as to improve the machining accuracy of workpiece.
Preferably, clamping nut is provided with the spanner being fixed on clamping nut.
Pass through above-mentioned technical proposal, clamping nut can be used for fastening the second pressure strip, prevent the second pressure strip from loosening,
One spanner being fixed on clamping nut is set on clamping nut, so facilitates the operation of worker, operating efficiency can be improved.
Preferably, straight pin is through the second locating piece both sides, and be provided with side of second locating piece away from fire grate with
The connected cylindrical grip of straight pin.
Pass through above-mentioned technical proposal, because long-term use of straight pin can wear, a cylinder is set on straight pin
Shape handle, aspect is changed so when straight pin wears, and ensure that positioning precision.
