The annular protrusion of arrangement and belt recess composition, it is sheathed on outside the drilling rod of drilling tool, and the drilling rod of its inner wall and drilling tool is separated with gap,
It is connected with the vertex of a cone end of the connecting portion.
Further, the drill bit of drilling rod exposes the 0~4cm of pars contractilis.
Further, the drill bit of drilling rod exposes the pars contractilis 2cm.
Further, 6~10cm of the pars contractilis internal diameter.
Further, the pars contractilis internal diameter 8cm.
Further, 0.5~1.5mm of the pars contractilis wall thickness.
Further, the pars contractilis wall thickness 1mm.
Further, 1.5~2.5mm of the connecting portion wall thickness.
Further, the connecting portion wall thickness 2mm.
Further, the length of the connecting portion is 4cm.
Further, air entry is additionally provided with the pars contractilis, it is used to connect getter device
Drilling tool dust guard provided by the utility model, design is reasonable, easy to operate, practicality is good.Effective collection structure
The dust produced with positions such as decoration stage wall, beam, plate, columns using hand drill drilling.
Brief description of the drawings
Fig. 1 is one using state structure diagram of the utility model drilling tool dust guard embodiment；
Fig. 2 be in the utility model drilling tool dust guard embodiment two connecting portion with the structure diagram of pars contractilis.
In figure, 1. pars contractilis, 101. air entries, 2. connecting portions, 3. drilling rods, 4. drilling tools.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Embodiment one：
A kind of drilling tool dust guard, as shown in Figure 1, including：Connecting portion 2 and pars contractilis 1, the connecting portion 2 are taper, because
The part that drilling rod 3 is installed for drilling tool 4 is taper, so, connecting portion 2 is matching taper, and connecting portion 2 is sheathed on drilling tool 4
Tapered front end, the pars contractilis 1 is corrugated pipe fitting, is made of the annular protrusion and belt recess that are alternately arranged vertically,
It is sheathed on outside drilling rod 3, its inner wall is separated with gap with drilling rod 3, it is connected with the vertex of a cone end of the connecting portion 2.
In the present embodiment, the shape of convex portion and recess can be arc-shaped, rectangle or other shapes.
In one optional embodiment of the present embodiment, as shown in Figure 1, the drill bit of drilling rod 3 exposes the distance of the pars contractilis 1
L3 is 0~4cm, it is preferable that the drill bit of drilling rod 3 exposes the pars contractilis 2cm.Be conducive to drill bit positioning, prevent pars contractilis 1 from blocking
Sight, if exposing apart from excessive, does not have the effect for collecting dust.
In one optional embodiment of the present embodiment, as shown in Figure 1,1 internal diameter L2 of the pars contractilis is 6~10cm, preferably
Ground, states 1 internal diameter 8cm of pars contractilis.Inner wall is separated with gap with drilling rod 3, if gap is too small, dust easily blocks, and influences drilling rod 3 and rotates,
If gap is excessive, drilling is hindered, is particularly boring the place of narrow space at point.
In one optional embodiment of the present embodiment, 1 material of pars contractilis is rubber, 0.5~1.5mm of wall thickness, preferably
Ground, the 1 wall thickness 1mm of pars contractilis.
In one optional embodiment of the present embodiment, 2 material of connecting portion is rubber, 1.5~2.5mm of wall thickness, preferably
Ground, the 2 wall thickness 2mm of connecting portion.
In one optional embodiment of the present embodiment, as shown in Figure 1, the length L1 of the connecting portion 2 is 4cm.
Operation principle：The connecting portion 2 on 4 front end sleeve of drilling tool, adjustment, after entangling firm completely, opens drilling tool 4, the drill bit of drilling rod 3
Close to boring point position, after slowly piercing structure 2cm, 1 front end of pars contractilis is close to drilled thing, as drill bit gos deep into, pars contractilis 1
It is adjacent to drilled thing and gradually tapers up, boring sites in curing forms closed cavity, after drill bit enters required depth, slowly receives and bores, pars contractilis 1
Clear-cutting forestland original length, the dust that whole boring procedure produces effectively are collected into pars contractilis 1.
Drilling tool dust guard provided by the utility model, design is reasonable, easy to operate, practicality is good.Effective collection structure
The dust produced with positions such as decoration stage wall, beam, plate, columns using hand drill drilling.
Embodiment two：
Embodiment two is the further improvement of embodiment one, and for embodiment one, difference is, such as Fig. 2 institutes
Show, add air entry 101, air entry 101 is arranged on pars contractilis 1, is connected with its inner cavity, for connecting getter device, institute
It can be wind turbine to state getter device.Wind turbine is outwards evacuated by air entry 101, is caused the inner cavity negative pressure of pars contractilis 1, is avoided dust
It is outer to dissipate.
In one optional embodiment of the present embodiment, air entry 101 is arranged at the head of pars contractilis 1, i.e., towards drill bit,
This position ensures that inspiratory effects are notable.
In one optional embodiment of the present embodiment, air entry 101 is arranged at the root of pars contractilis 1, the head of connecting portion 2
Or the junction of pars contractilis 1 and connecting portion 2, herein will not after connecting upper air intake duct with preferable structural strength, air entry 101
Influence of crust deformation is caused to pars contractilis 1.
The protection scope of the utility model is not limited thereto.Those skilled in the art institute on the basis of the utility model
