By adopting the technical scheme, when the slotting cutter body is installed, the positioning groove in the slotting cutter body is matched with the corresponding part in the cutter handle, and then the slotting cutter body is fixed in the installing hole through the insertion of the screw, so that the slotting cutter body is convenient to position.

The utility model discloses further set up to, the perpendicular cross-section of constant head tank is the V-arrangement, just the smooth transition in bottom of constant head tank is provided with the fillet, just constant head tank both sides contained angle is 120 degrees to 150 degrees.

Through adopting above-mentioned technical scheme, fillet and the angle of restriction constant head tank not only can reduce stress concentration, less slot cutter's fracture to improve its life, can be with more reliable fixed of slot cutter body moreover.

The utility model discloses further set up to, two inclined planes have been seted up respectively at the both ends of first surface, just the inclined plane distributes the both sides of constant head tank.

Through adopting above-mentioned technical scheme, when the both ends setting of first surface was on same plane, the groove sword body was when the cutting, and the side is direct to be great with the air contact then the great resistance that produces, consequently sets the inclined plane to at the both ends of constant head tank length direction, can reduce the resistance of cutting.

The utility model discloses further set up to, the chip groove has been seted up on the inclined plane, be provided with the chip removal hole in the chip groove.

Through adopting above-mentioned technical scheme, when not setting up the chip groove, the sweeps that produce during the cutting directly drops subaerial, and when the speed of cutting was too fast, the sweeps that the cutting produced directly splashes away easily. Therefore, the chip grooves are arranged, splashing of scraps can be reduced, and the safety factor of workers is improved. The setting in chip removal hole can be with the sweeps clean up of escape trough inside on the one hand, and on the other hand can reduce splashing of sweeps, improves staff's factor of safety.

The utility model discloses further set up to, the perpendicular cross-section in chip removal hole sets up to conical, the main aspects in chip removal hole are kept away from the chip pocket sets up.

By adopting the technical scheme, if the longitudinal section of the chip removal hole is cylindrical, the length of the chip removal hole is longer, so that blockage is easy to generate during chip removal. If the chip removal hole is conical, but the big end of the chip removal hole is arranged towards the chip groove, the volume of waste materials entering the chip removal hole is larger than the volume of waste materials discharged from the chip removal hole, and therefore the chip removal hole is more easily blocked. Therefore, the vertical section of the chip removal hole is conical, but the large end of the chip removal hole is arranged far away from the chip groove, so that waste chips can be cleaned conveniently, and the blockage situation is reduced.

The utility model discloses further set up to, the mounting hole is close to the one end of second surface sets up to the circular conical bore, the circular conical bore with be provided with the through-hole between the chip removal hole.

Through adopting above-mentioned technical scheme, the coolant oil or flush fluid can wash the sweeps of chip groove inside through the through-hole, and the setting of taper hole, on the one hand, can be convenient for hide of screw, and on the other hand, the installation that can be convenient for between screw and the slotting tool body is fixed.

The utility model discloses further set up as, all be provided with anti-skidding line on two internal faces of constant head tank.

Through adopting above-mentioned technical scheme, the friction between constant head tank and the handle of a knife can be increased in the setting of antiskid line, makes connection between the two more firm.

The novel further setting is that the material of groove sword body is high-speed steel material.

By adopting the technical scheme, the high-speed steel material has good processing performance and good matching of strength and toughness, and is a main material for manufacturing thin-blade and impact-resistant metal cutting tools. Therefore, the wear of the slotting cutter body can be reduced by the high-speed steel material, and the service life of the slotting cutter body is prolonged.

To sum up, the utility model discloses following beneficial effect has:

1. the groove cutter can be installed and positioned by arranging the V-shaped positioning groove and the V-shaped mounting hole;

2. the effect of reducing cutting resistance can be achieved through the arrangement of the inclined surface;

3. through the setting of chip groove and chip removal hole, can play the effect that splashes that reduces the sweeps.
