Detailed description of the invention
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The utility model embodiment as shown in Figure 1, comprises drill bit 1, chamfering blade 2, controls pin 3, spring 4, knife bar 5, pin 6, adjustment screw 7.
As shown in Figure 1 and Figure 2, to have the chamfering cutter hub of Bicylindrical Surface Intersect structure and sword angle be the symmetrical cutting edge up and down of 90 ° to chamfering blade 2; Chamfering cutter hub top has V-arrangement inclined-plane; Control pin 3 belows and there is V-arrangement inclined-plane; Knife bar 5 has center mounting hole and the chamfering blade installing hole perpendicular to the Bicylindrical Surface phase perforation shape of knife bar 5; The chamfering blade installing hole of the center mounting hole of knife bar 5 and knife bar 5 connects mutually; Drill bit 1 is connected with knife bar 5 screw thread quick changes; Chamfering blade 2 is arranged in a side chamfering blade installing hole of knife bar 5.
