Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 holds bits portion, 11 chip pockets, 12 protrusions, 13 gear chip, 14 cylindrical bodies；2 processing departments, 21 central spindles, 211 connections
End, 212 processing ends, 2,121 first cutting edges, 2,122 second cutting edges, 22 lands, 23 grooves；3 drillstocks, 31 cylinders, 32 rotary tables,
321 large end faces, 322 small end faces.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The embodiments of the present invention: referring to Fig. 1, a kind of building brill wall drill bit, including hold bits portion 1,2 and of processing department
Drillstock 3, the major design point of the utility model are exactly to hold bits portion 1.Hold bits portion include chip pocket 11, protrusion 12, gear chip 13,
Cylindrical body 14, wherein chip pocket 11 be mainly by cylindrical body 14 and protrusion 12 in conjunction with and formed.That is the periphery of cylindrical body 14
Equipped with multiple raised 12, it is formed chip pocket 11 between these protrusions 12, height of the protrusions 12 apart from cylindrical body 14 is not
Less than 2 centimetres, because only that such can accommodate the extra clast of processing department 2.The main purpose of gear chip 13 is exactly anti-
The case where only dust is flown upward during bit operation, gear chip 13 are arranged in the periphery of protrusion 12, keep off the material of chip 13
Preferably iron plate, naturally it is also possible to using other materials, such as plastics, hard steel, aluminium flake etc..Gear chip 13 is sized to be slightly smaller than
Protrusion 12 can make one end and 2 seamless interfacing of processing department of keeping off chip 13 in this way, while keep off the other end and drillstock 3 of chip 13
Rotary table small end face 322 formed an inclined gradient, when chip pocket 11 accommodate clast expired when, can be by extra clast
It is rejected on ground, the clast for forming heap at this time not will cause dusty situation, but freely be slipped on ground.
Processing department 2 mainly includes central spindle 21, land 22 and groove 23, and wherein land 22 and groove 23 are located at the outer of central spindle 21
The surface of side, and central spindle 21 is additionally provided with connecting pin 211 and processing end 212 in itself, and the diameter of connecting pin 211 is greater than processing end
212 diameter, such design can increase processing 212 working efficiency of end, and the design of connecting pin 211 is main is exactly and appearance
Cylindrical body 14 in bits portion 1 links together, while the land 22 of 21 outer surface of central spindle links together with protrusion 12, groove 23
It links together with chip pocket 11, forms a clear and coherent slideway, make it possible to accommodate more clast.It processes end and is equipped with the
One cutting edge 2121 and the second cutting edge 2122, the first cutting edge 2121 and the second cutting edge 2122 are outer by the processing end
Center position extension of the edge to the processing end, first cutting edge 2121 and the second cutting edge 2122 are crossed to form sharp
Angle, that is to say, that the first cutting edge 2121 and the second cutting edge 2122 are inclined knife face, while being along axial line and prolonging
Sharp angle is crossed to form after stretching.Resistance can be reduced during use, increase the sword degree used.The number of protrusion 12
Amount is twice of the groove 23, and all grooves 23 can be mapped by such design with chip pocket 11, in order to avoid groove
23 and the quantity of chip pocket 11 do not correspond to.
Drillstock 3 includes rotary table 32 and cylinder 31, and cylinder 31 is the cylinder of polygon, and such cylinder 31 is being inserted into electric drill
Hole in when, conveniently block drill bit, at the same can also cooperate it is a variety of bore object tools uses.Rotary table 32 is equipped with 321 He of large end face
Small end face 322, the main function of large end face 321 are exactly to be attached with cylinder, the effect of small end face 322 be exactly by small end face and
Cylindrical body 14 connects, while also cooperating with chip pocket 11, falls to the ground the free skating of extra clast.Small end face 322 is straight
Diameter, the diameter of the cylindrical body 14 are consistent with the diameter of the connecting pin 211, and such design is to form unified rule
Lattice are more conducive to the receiving of clast.
