Abstract
The invention belongs to the technical field of electric appliances and particularly relates to and discloses a torsion cup of an electric wrench. The torsion cup of the electric wrench comprises an annular body; one end of the annular body is provided with a gear ring; the position of the outer side of the annular body, which is located at one end of the gear ring, is provided with scale values; the inner side of the annular body is provided with a plurality of locking strips; the gear ring is provided with a locking block. The torsion cup of the electric wrench has the advantages of being simple in structure and convenient to use, enabling torque values to be well determined, enabling torque to be accurate and enabling the operation to be simple and convenient.
Description
Technical field
The invention belongs to the electric tool technical field, relate in particular to a kind of torsion cup 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, used a kind of electric wrench, existed the situations such as torsional forces deficiency in the process of using.
Summary of the invention
The object of the invention is to solve above-described technical problem, a kind of torsion cup of electric wrench is provided, its technical scheme is as follows:
A kind of torsion cup of electric wrench, it is characterized in that, the torsion cup of described electric wrench comprises ring bodies, one end of described ring bodies is provided with ring gear, the end place that the outside of described ring bodies is positioned at ring gear is provided with scale value, the inboard of described ring bodies is provided with some card articles, and described ring gear is provided with fixture block.
Optimal way is that the outside of described ring bodies is provided with some anti-slip tanks.
Optimal way is that described ring gear is the semi-circular ring gear.
Optimal way is that the joint in the outside of described anti-slip tank and ring bodies is provided with smooth bevel.
The torsion cup of electric wrench provided by the invention, when in use, whole ring bodies is to be set on the gear-box group, and the inboard of ring bodies is provided with some card articles, and described ring gear is provided with fixture block can be so that determining to play positioning action preferably after torque value.During concrete the use, at first determine torque value, after then the rotary annular body reaches torque value, just can carry out work.When work proceeds to when completing, its fixture block can block, thereby quits work.
The outside of ring bodies of the present invention is provided with some anti-slip tanks.Cross anti-slip tank and can hold preferably ring bodies so that when determining torque value toward ring bodies, relatively the labour-saving is turned round ring bodies under scale corresponding to its torque value.
Ring gear of the present invention is the semi-circular ring gear.Can reduce the difficulty of making so that reduce technological process when making, make product can be faster, make more simply and easily.
The joint in the outside of anti-slip tank of the present invention and ring bodies is provided with smooth bevel.Smooth bevel makes whole product more attractive in appearance, makes also simultaneously that feel is more good when in use, convenient operation.
The present invention is simple in structure, and is easy to use, can be good at determining torque value, and makes torsion more accurate, makes operation more easy.
Description of drawings
Fig. 1 is schematic diagram of the present invention.
The specific embodiment
Illustrate embodiment below in conjunction with Fig. 1:
A kind of torsion cup of electric wrench, it is characterized in that, the torsion cup of described electric wrench comprises ring bodies 1, one end of described ring bodies 1 is provided with ring gear 2, the end place that the outside of described ring bodies 1 is positioned at ring gear 2 is provided with scale value 3, the inboard of described ring bodies 1 is provided with some card articles 4, and described ring gear 2 is provided with fixture block 5.
Optimal way is that the outside of described ring bodies 1 is provided with some anti-slip tanks 6.
Optimal way is that described ring gear is the semi-circular ring gear.
Optimal way is that the joint in the outside of described anti-slip tank and ring bodies is provided with smooth bevel.
The torsion cup of electric wrench provided by the invention, when in use, whole ring bodies is to be set on the gear-box group, and the inboard of ring bodies is provided with some card articles, and described ring gear is provided with fixture block can be so that determining to play positioning action preferably after torque value.During concrete the use, at first determine torque value, after then the rotary annular body reaches torque value, just can carry out work.When work proceeds to when completing, its fixture block can block, thereby quits work.
