Detailed description of the invention
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with thisThe accompanying drawing of utility model embodiment, retouches clearly and completely to the technical scheme of the utility model embodimentState. Obviously, described embodiment is a part of embodiment of the present utility model, instead of whole enforcementExample. Based on described embodiment of the present utility model, those of ordinary skill in the art are without creative laborThe every other embodiment obtaining under moving prerequisite, belongs to the scope that the utility model is protected.
Referring to Fig. 1,2,3, processing carburetor drill bit, comprises handle of a knife 1, and brill in handle of a knife front endSword body 2, handle of a knife is made up of the first cylindrical handle 3, the second cylindrical handle 4, the first cylindrical handle, the second cylindrical handleAxis conllinear, the external diameter of the first cylindrical handle is greater than the external diameter of the second cylindrical handle, the first cylindrical handle and the second cylinderThe junction outer peripheral face of handle is circular cone 5, is convenient to increase the degree of depth of drill bit machining hole;
Drill lip body is arranged at the second cylindrical handle front end, on the side face at drill lip body in the second cylindrical handle front end, establishesBe equipped with two helical edges 6, between helical edges, form helical flute 7, for chip discharge, before drill lip bodyEnd face is provided with end sword, and end sword and drill lip body axis direction form the first sword 8 of included angle A, and with brillBetween the end of the second sword 9, the first swords, the second sword and the helical edges of sword body axis direction formation included angle B, formSkewed cutting face, end 10. Included angle A, B can select between 50 °-60 °.
In the first cylindrical handle, offer in square pilot hole 11, the second cylindrical handles that connect both ends of the surface and offer perforationThe circular pilot hole 12 of both ends of the surface, square pilot hole is connected with circular pilot hole, the size of square pilot holeBe greater than the diameter of circular pilot hole, one side of circular pilot hole and square pilot hole is tangent, and drill lip body afterbody prolongsStretch out columniform assembling post 13, this assembling post stretches in square pilot hole through circular pilot hole, assembling postAnd between circular pilot hole, adopt and be threaded, in the first cylindrical handle, be provided with for locking and stretch into square dressJoin the locking device that assembles post in hole, locking device comprises along the first cylindrical handle diametric(al) and inserts square assemblingTie down screw 14 in hole, offers multiple and locking screw at the assembling post outer peripheral face stretching in square pilot holeThe screw 15 of bar threaded engagement, screw is arranged at intervals on assembling post.
