Abstract
The utility model discloses an electric drill dedicated for building construction. The electric drill comprises an electric drill body and a drill bit. A drilling rod of the drill bit is sleeved with a plastic locating ring in a sliding mode. A plastic countersunk head screw is arranged on the plastic locating ring. The electric drill can accurately control the distance from the front end of the drill bit to the plastic locating ring, namely, the drilling depth. At hole drilling time, an operator does not need to consider and control the potency dimension of hole drilling, when the depth of a hole reaches requirements, the plastic locating ring is just located at the end port of the hole and prevents the drill bit from drilling. Consequently, the drilling depth can be accurately controlled, and construction efficiency and quality can be improved.
Description
Technical field
The utility model relates to electric hand drill, especially a kind of construction electric drill special.
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 construction electric drill special 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 construction electric drill special of the utility model, comprise electric drill body and drill bit, and slip cap is provided with the plastics locating ring on the drilling rod of described drill bit, and described plastics locating ring is provided with the plastics sunk screw.
Slip cap is provided with abutment sleeve between the drill bushing of plastics locating ring and electric drill body.
Compared with prior art the beneficial effects of the utility model are: owing to having adopted slip cap on the drilling rod of described drill bit to be provided with the plastics locating ring, described plastics locating ring is provided with the plastics sunk screw, this structure, can accurately control the distance of chisel edge to the plastics locating ring, 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 plastics locating ring just in time is positioned at the port in hole and stops bit bore, thereby the degree of depth of keyhole, improve efficiency of construction and quality accurately.
Further beneficial effect is: the employing of abutment sleeve can stop that the plastics locating ring moves to the drill bushing direction, avoids the appearance of drilling depth error.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model is further optimized.
The specific embodiment
As illustrated in fig. 1 and 2, a kind of construction electric drill special of the utility model, comprise electric drill body 1 and drill bit 2, slip cap is provided with plastics locating ring 3 on the drilling rod of described drill bit 2, described plastics locating ring 3 is provided with plastics sunk screw 4, and described plastics sunk screw 4 is used for plastics locating ring 3 is fixed in the drilling rod of drill bit 2.As preferably, slip cap is provided with abutment sleeve 6 between the drill bushing 5 of plastics locating ring 3 and electric drill body 1.In actual applications, abutment sleeve 6 is selected plastics to make and the different lengths specification is arranged.
