Abstract
The utility model belongs to the technical field of electric tools, and particularly relates to a chuck of an electric wrench. The chuck of the electric wrench is characterized by comprising a body, wherein a rotating shaft is arranged in the body, the front end of the rotating shaft is connected with a clamping nozzle, and the rear end of the rotating shaft is provided with a connecting and fixing part. The chuck of the electric wrench is simple in structure, convenient to use, and capable of well clamping a screw or a rotating head so that the screw or the rotating head cannot fall off easily, and saves more effort in use.
Description
Technical field
The utility model belongs to the electric tool technical field, relates in particular to a kind of chuck of electric wrench.
Background technology
Spanner is the instrument of tightening or unscrew screw, nut etc.Previously used spanner is a kind of installation and removal instrument commonly used.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner usually is shaped with clamp holder section and applies the external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut are held bolt or nut.Apply external force along the screw thread rotation direction at shank during use, just can twist bolt or nut.This type of spanner needs artificial twisting, so very inconvenient when using on engineering.At present, use a kind of electric wrench, solved the problems referred to above.But the chuck of this type of electric wrench is easy to cause coming off of screw or rotary head when in use, uses cumbersome.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of chuck of electric wrench is provided, and its technical scheme is as follows:
A kind of chuck of electric wrench, is characterized in that, the chuck of described electric wrench comprises body, in described body, is provided with rotating shaft, and the front end of described rotating shaft is connected with dop, and the rear end of described rotating shaft is provided with connection fixture.
Optimal way is that the front end of described body evenly offers some anti-slip tanks.
Optimal way is, described dop is the circular cone shape body, and the point diameter of described dop is 3-6mm.
The chuck of the electric wrench that the utility model provides, when in use, dop is clamped screw or rotary head.And the rear end of rotary head is provided with connection fixture, connection be the gear-box group, thereby can offer the power that chuck rotates.The power provided by the gear-box group, make rotating shaft rotate, thereby driven the rotation of dop, finally makes screw or rotary head be screwed into the position of appointment under rotating, and reached purpose.
The front end of body described in the utility model evenly offers some anti-slip tanks.Can hold preferably body so that when in dop, putting into screw or rotary head by anti-slip tank, relatively screw or rotary head are clamped in labour-saving on dop.
Dop described in the utility model is the circular cone shape body, and the point diameter of described dop is 3-6mm.Can, so that dop is better clamped screw or rotary head, be not easy to come off.
The utility model is simple in structure, easy to use, and can be good at clamping screw or rotary head and make it be not easy to come off, and also in use also more laborsaving.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Illustrate embodiment below in conjunction with Fig. 1:
A kind of chuck of electric wrench, is characterized in that, the chuck of described electric wrench comprises body 1, in described body 1, is provided with rotating shaft 2, and the front end of described rotating shaft 2 is connected with dop 3, and the rear end of described rotating shaft 2 is provided with connection fixture 4.
Optimal way is that the front end of described body 1 evenly offers some anti-slip tanks 5.
Optimal way is, described dop is the circular cone shape body, and the point diameter of described dop is 3-6mm.
The chuck of the electric wrench that the utility model provides, when in use, dop is clamped screw or rotary head.And the rear end of rotary head is provided with connection fixture, connection be the gear-box group, thereby can offer the power that chuck rotates.The power provided by the gear-box group, make rotating shaft rotate, thereby driven the rotation of dop, finally makes screw or rotary head be screwed into the position of appointment under rotating, and reached purpose.
