Through above-mentioned technical scheme, make chip groove and constant head tank intercommunication through the breach, when the drill bit drills, owing to need mill the plane to the outside simultaneously, the chip removal of drill bit can only be toward the fixed slot internal row, through setting up the breach, can make the drill chip of drill bit arrange to the chip groove from the breach and discharge to make drilling operation more convenient.

Furthermore, the chip groove is respectively an installation side wall and a guide side wall along two side walls of the circumferential direction of the installation seat, the installation groove is correspondingly located on the installation side wall, and one end, close to the fixed shaft, of the guide side wall is in circular arc transition with the groove bottom of the chip groove.

Through above-mentioned technical scheme, when the sweeps of drilling pass through the chip groove and discharge, the circular arc transition can lead the chip removal to make the chip removal more convenient.

Furthermore, the chip groove evenly is provided with two along mount pad circumference, and two lateral walls mutually perpendicular of chip groove set up.

Through above-mentioned technical scheme, through the in-service use, two set up to best scheme, the structure of blade holder is more stable, also makes the rotation of blade holder more stable in addition.

Further, the diameter of the fixed shaft is gradually reduced towards the direction far away from the mounting seat.

Through above-mentioned technical scheme, the convergent setting of fixed axle, when the fixed axle need install into on the main shaft, can make the inserting of fixed axle more convenient. In addition, due to the arrangement of the reducing device, the outer side wall of the fixing shaft can be abutted against the inner wall of the hole corresponding to the main shaft, so that the fixing shaft can be positioned more accurately, and the coaxiality of the cutter holder and the main shaft is better.

Furthermore, the locating slot penetrates through the mounting seat and the fixing shaft along the axis direction of the locating slot.

Through above-mentioned technical scheme, when the blade holder was installed to the drill bit needs, can insert the location from the blade holder other end through the gag lever post to the length that the control drill bit stretched into, when the wrong bolt of twisting on first screw hole, the drill bit was close to the one end of fixed axle and can contradict and fix a position in the gag lever post, thereby makes the installation of drill bit more accurate.

Furthermore, the outer side wall of the mounting seat is further provided with a countersunk groove, and the countersunk groove is arranged corresponding to the first threaded hole and used for placing the top of the bolt.

Through above-mentioned technical scheme, set up the countersunk head groove, when making the screw bolt of screwing in on the first screw hole through the countersunk head groove, the bolt can be hidden as in the mount pad completely, has reduced the condition that the bolt evagination collided with the foreign object.

Compared with the prior art, the beneficial effects of the utility model are that:
