Abstract
The utility model discloses an eccentric formula double offset ring spanner head, including wrench end body, plum blossom hole and plum blossom hole outlying ring platform, the anterior segment of wrench end body is a strip shaped plate, and the back end be the cylinder, and the afterbody of cylinder has the interface of pegging graft with the torque wrench pole, and the axis of cylinder and the central line coincidence of strip shaped plate, the axis of plum blossom hole and ring platform lie in the central line of a shaped plate, the axis misalignment of plum blossom hole and ring platform, and the wrench end top is partial to to the axis in plum blossom hole. Because the utility model discloses a plum blossom hole erroneous tendency wrench end top, when running into by certain one side space of tight bolt when comparatively narrow and small, the wrench end can overlap on the bolt, and then can implement torque wrench to tightening by bolt tightly.
Description
Technical field
The utility model belongs to spanner field, refers to a kind of double offset ring spanner at hand.
Background technology
Double offset ring spanner is a kind of common tool, due to double offset ring spanner when nut is tightened its driving end can entangle completely it is suitable
Nut with model, will not slip from nut, therefore double offset ring spanner is also at hand a kind of matching used with torque wrench common
Instrument.Respectively there is a circle being integrated with driving end body and concentric with plum blossom hole at existing double offset ring spanner plum blossom hole two ends at hand
Land, annulus platform is essential as the reinforcing section of driving end intensity, and its thickness (difference of internal-and external diameter) can't be too small.
At hand when running into more narrow and small by certain side space of tight bolt, driving end cannot be enclosed within bolt this double offset ring spanner, it is impossible to
Use.
The content of the invention
The purpose of this utility model is to solve existing double offset ring spanner at hand in the non-serviceable problem of a certain small space, is carried
Go out a kind of centering type double offset ring spanner at hand.
Realizing the technical scheme of above-mentioned purpose is：A kind of centering type double offset ring spanner at hand, including driving end body, plum blossom hole and
The annulus platform of plum blossom hole periphery, it is characterised in that the leading portion of the driving end body is stripe board, and back segment is cylinder, described
The afterbody of cylinder overlaps with the interface with torque wrench bar grafting, the axis of cylinder with the center line of stripe board, plum blossom
The axis of hole and annulus platform is located on the center line of stripe board, and the axis of plum blossom hole and annulus platform is misaligned, the axis of plum blossom hole
Deflection driving end top.
Further, the interface for internal-hole type, i.e. cylinder afterbody be a blind hole for cylinder, the axis and circle of blind hole
The axis of cylinder overlaps.
Further, there is radial positioning hole on the hole wall of the blind hole.
Further, the interface is projective table type, i.e., described cylinder afterbody is a boss for cylinder, the boss
Axis overlaps with the axis of cylinder.
Further, there is radial positioning hole on the boss.
It is more narrow by certain side space of tight bolt when running into due to plum blossom hole of the present utility model deflection driving end top
Hour, driving end can be enclosed within bolt, and then can implement torque wrench to being tightened by tight bolt.Due to plum blossom hole periphery
Annulus platform it is cylindrical constant, its intensity is almost unchanged, therefore does not interfere with the intensity of driving end.

Fig. 2 is the A-A sectional views of Fig. 1.
Fig. 3 is the front schematic view of another embodiment of the utility model.
Fig. 4 is the B-B sectional views of Fig. 1.
In figure：1. driving end body, 101. stripe boards, 102. cylinders, 2. plum blossom hole, 3. annulus platform, 4. blind hole, 5. convex
Platform, 6. location hole, a. plum blossom axially bored lines, b. annulus platform axis, the center line of c. stripe boards.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 3, the utility model includes the annulus platform of driving end body 1, plum blossom hole 2 and the periphery of plum blossom hole 2
3, the leading portion of driving end body 1 is stripe board 101, and back segment is cylinder 102, and the afterbody of cylinder 102 is carried and torque wrench
The interface of bar grafting, the axis of cylinder 102 overlaps with the center line c of stripe board, plum blossom axially bored line a and b, annulus platform axis
In on the center line c of stripe board, and plum blossom axially bored line a and annulus platform axis b are misaligned, plum blossom axially bored line a deflection driving ends
Top, that is, be partial to the front end of stripe board 101.
As shown in Figure 1 and Figure 2, the interface of the afterbody of cylinder 102 is internal-hole type in the present embodiment.That is, the afterbody of cylinder 102
It is the cylindrical blind hole 4 of and torque wrench bar grafting, the axis of blind hole 4 overlaps with the axis of cylinder 102, blind hole 4
Hole wall be provided with a radial positioning hole 6.This driving end is adapted to range as the shaft type moment of torsion that docks of below 1000N.m is pulled
Hand lever is docked.
As shown in Figure 3, Figure 4, the interface of the afterbody of cylinder 102 is projective table type in the present embodiment.That is, the afterbody of cylinder 102
It is the cylindrical boss 5 of and torque wrench bar grafting, the axis of boss 5 overlaps with the axis of cylinder 102, boss 5
On have radial positioning hole.This driving end adapts to the butt muff formula wide range torque wrench bar for more than 1000N.m with range
Docking.
