Accompanying drawing explanation
Fig. 1 is the front view that the diameter adjustable staged metal that this utility model preferred embodiment is provided bores.
Fig. 2 is the left view that the diameter adjustable staged metal that this utility model preferred embodiment is provided bores.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not used to limit this utility model.
Referring to Fig. 1, Fig. 2, the diameter adjustable staged metal that this utility model preferred embodiment is provided bores 100,
Including drill bit 10 and drillstock 20, in the present embodiment, described drillstock 20 is provided on the center of circle line of drill bit 10, and relative to brill
10 fixing connect, it is preferable that drillstock 20 and drill bit 10 are set to integral structure.It is appreciated that the center of circle of described drill bit 10
Line is the center of gravity line of drill bit 10, and is fixed together by the line of drillstock 20 with drill bit 10 center of gravity place, it is simple to this staged gold
Belonging to brill 100 operationally, drillstock 20 drives stability when rotating to drill bit 10.
Wherein, described drill bit 10 includes the first cutting head 11, and is arranged in order multiple second cutting heads 12 of setting, wherein
Each second cutting head 12 is set to the step structure that length on axial direction is equal, and adjacent two the second cutting heads 12
End face coincides, and the first cutting head 11 is set to vertebral body structure at the side end away from the second cutting head 12, opposite side
End face coincides with the end face of adjacent second cutting head 12.So this drill bit 10 is when concrete drilling operation, first with
On one cutting head 11, the head of vertebral body shape pierces on workpiece, then stretching into successively with stair-stepping second cutting head along drill bit 10
12 carry out punching effect.It is appreciated that the first cutting head 11 is set to vertebral body structure, it is simple to this first cutting head 11 is to workpiece
Punching stretch into, and the stair-stepping formal structure of the second cutting head 12 arrange so that the hole that this drill bit 10 is bored is stepped.
It is further opened with 2 spiral chip areas 13 on the drill bit 10 of the present embodiment, and every chip area 13 is by way of brill
Each second cutting head 12 on 10, in the present embodiment, 2 described chip areas 13 also by way of the first cutting head 11, this
This drill bit 10 of sample is when bore operation, and its first cutting head 11 and the second cutting head 12 crumble produced by boring procedure is just
Can successfully discharge smoothly from this chip area 13.It is appreciated that described staged metal bores 100 and entering with driving instrument
Luggage timing, can be set to the hand of spiral of this chip area 13 bore direction of rotation during 100 work with this staged metal
Equally, to improve further crumble chip removal when this staged metal is bored 100 bore operation by this chip area 13.Further,
It is labeled with scale (not shown) on described chip area 13, is labeled with the external diameter to each second cutting head 12 so that these rank
Ladder type metal brill 100 operationally, can be by the external diameter of its shoulder hole beaten at the scale judgement of mark on chip area 13
Size.
On the periphery of described drillstock 20, annular offers multiple arc-shaped bar groove 21, and offers one on this drillstock 20
