Abstract
The utility model discloses an electric drill used for construction. The electric drill used for construction comprises an electric drill body and a drill bit, wherein a positioning block provided with a through hole is arranged at the upper end of the electric drill body, the axis of the through hole is parallel to the drill bit, a positioning rod is arranged in the through hole in a sliding and sleeved mode, and a threaded ejector pin is further arranged on the positioning block. The electric drill used for construction is capable of controlling drilling depth accurately and improving construction quality.
Description
Technical field
The utility model relates to electric hand drill, especially a kind of electric drill for construction.
Background technology
Electric drill is instrument commonly used in construction, curtain wall is installed, electrical equipment, furred ceiling etc. are installed, and all will use.The defect that existing electric drill exists is: the degree of depth of keyhole accurately.In construction, the object of electric drill is body of wall mostly, and quality is softer than iron and steel, and it is bad that strength is controlled, and is easy to bore dark or bores shallowly, affects construction quality.Especially during pre-buried expansion bolt, the depth of boring, be directly connected to the soundness of expansion bolt.
The utility model content
The purpose of this utility model is: a kind of electric drill for construction is provided, and the degree of depth of keyhole, improve construction quality accurately.
For achieving the above object, the utility model can be taked following technical proposals:
A kind of electric drill for construction of the utility model, comprise electric drill body and drill bit, be provided with the locating piece with through hole in the upper end of described electric drill body, the axis of described through hole is parallel with described drill bit, in through hole, slip cap is provided with backstay, also is provided with the screw thread thimble on described locating piece.
Leading section at described backstay is provided with limit switch, and described limit switch is connected with the power switch of electric drill body.
compared with prior art the beneficial effects of the utility model are: owing to having adopted in the upper end of described electric drill body, be provided with the locating piece with through hole, the axis of described through hole is parallel with described drill bit, in through hole, slip cap is provided with backstay, also be provided with the screw thread thimble on described locating piece, this structure, can accurately control the distance of chisel edge to the backstay front end, it is the distance of drilling depth, when the bores are being drilled, the operator needn't consider the dynamics with keyhole, the degree of depth when hole reaches requirement, the end face in backstay front end conflict hole also stops bit bore, thereby the degree of depth of keyhole accurately, improve efficiency of construction and quality.
Further beneficial effect is: the leading section at described backstay is provided with limit switch, and when the degree of depth in hole got into the degree of depth of requirement, limit switch disconnected, and drill bit stops boring automatically, guarantees accurate drilling depth.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of electric drill for construction of the utility model, comprise electric drill body 1 and drill bit 2, be provided with the locating piece 3 with through hole in the upper end of described electric drill body 1, the axis of described through hole is parallel with described drill bit 2, in through hole, slip cap is provided with backstay 4, also is provided with screw thread thimble 5 on described locating piece 3.As preferably, be provided with limit switch 6 at the leading section of described backstay 4, described limit switch 6 is connected with the power switch of electric drill body 1.
