Further, the height H of the groove is larger than the height L of the clamping ring. Through this setting avoid lifting adjusting screw to contact simultaneously with grooved top and bottom when rotatory and produce the friction, effectively reduce frictional force, make operating personnel operate more easily, be convenient for adjust the knife rest height. Still further, the top of lift adjusting screw is provided with the regulation hole that is the hexagon. Through the adjusting hole that sets up, be convenient for utilize the instrument to adjust lift adjusting screw, easy operation conveniently adjusts the knife rest height.
In order to guarantee the precision of the tool apron, preferably, a groove is arranged on the side, back to the dovetail groove, of the tool apron and communicated with the through groove. When utilizing fasteners such as screw rod to fix the tool rest, its screw rod head can hide in the recess and not evaginate, avoids foreign matter such as screw rod head to take place the contact with the work piece, precision when can ensure the blade holder and use, and the structure is succinct moreover, avoids the sweeps during processing to splash in the regulation hole.
The utility model discloses the implementation provides effective effect: the utility model discloses a blade holder cuts off adopts components of a whole that can function independently fine setting blade holder, utilizes the screw can finely tune cutter height in center. The service life of the cutter can be prolonged by adjusting the correct center height, the finish of the machined surface is improved, and the tail nail of the cut-off surface can be smaller when the cut-off cutter is used.
