Description
Technical field
The utility model relates to spanners, more particularly to the Optimal improvements of spanner structure.
Background technique
Spanner is a kind of common installation and removal tool.Bolt, screw, nut and other spiral shells are twisted using lever principle
Line tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is usually formed with clamp holder in the one or both ends of shank
Portion applies external force shank and applies external force.Threadingly direction of rotation can twist bolt or nut in shank application external force when use,
Spanner usually uses structural carbon steel or alloy structure steel making.
The sets of holes of box spanner are normally more bigger than the bolt of dimension or nut；When the bolt twisted is located at the depth of component
Place, is not easy to observe the positional relationship between bolt head and sets of holes, and hand need to hold the end of the other end of spanner at this time, obtains
Longer to protrude into distance, the specification of sets of holes is slightly larger than the specification of bolt, and sets of holes are easy to slide from the head of bolt to bolt
Bar portion needs repeatedly with feeling to be adjusted, and repeatedly after adjustment, the symptoms such as aching easily occurs in operator's hand are seriously affected
Working efficiency.
Utility model content
The utility model in view of the above problems, provide it is compact-sized rationally, install simple processing, improve service efficiency
Floating folder double offset ring spanner.
The technical solution of the utility model is: including spanner handle and the spanner for being mounted on spanner handle one end, which is characterized in that
The spanner is equipped with the elastic neck of a no less than circle, is equipped with the open type for acting on bolt outer surface in the elastic neck
Retainer ring；The diameter of the elastic neck is greater than the outer diameter of the open type retainer ring.
The upper corner of the inner sidewall of the open type retainer ring and lower corner are respectively equipped with lead-in angle.
The elastic neck and the axle center of the spanner are perpendicular.
The elastic neck is located at the medium position of the spanner.
It include spanner handle and the spanner for being mounted on spanner handle one end in the utility model, spanner is equipped with the elastic card of a circle
Slot, elastic neck is interior to be equipped with the open type retainer ring for acting on bolt outer surface；When bolt is located at open type retainer ring, open type retainer ring
Flexible deformation occurs, bolt will be clamped, prevents from pulling hole sliding from bolt.This case structure simple processing, it is easy for installation, it solves
The problems such as sets of holes spanner easily slides at present.So the utility model has compact-sized reasonable, installation simple processing, raising spanner
The features such as service efficiency.

Specific embodiment
The utility model as shown in figs. 1-7, including spanner handle 1 and the spanner 2 for being mounted on 1 one end of spanner handle, the spanner 2
It is equipped with the elastic neck 3 of a no less than circle, is equipped with the open type retainer ring for acting on 6 outer surface of bolt in the elastic neck 3
4；The diameter (length of A in figure) of the elastic neck 3 is greater than the outer diameter of the open type retainer ring 4.
As shown in Fig. 2, open type retainer ring 4 is slightly stretched out out of latch 5 that pull in mouth, when open type retainer ring 4 is set in bolt 6
6, bolt lateral surfaces when, as shown in figure 3, flexible deformation occurs for open type retainer ring 4, the diameter of elastic neck 3 is greater than opening
The outer diameter of formula retainer ring 4, in order to provide deformation space to open type retainer ring 4.When working, the elastic reaction of open type retainer ring 4 will
Bolt 6 is clamped, prevents from pulling hole sliding from bolt 6.
The upper corner of the inner sidewall of the open type retainer ring 4 and lower corner are respectively equipped with lead-in angle 41.Convenient for open type card
Circle 4 is smoothly fastened on 6, bolt, realizes clamping action.
The elastic neck 3 and the axle center of the spanner 2 are perpendicular.
The elastic neck 3 is located at the medium position of the spanner 2.Side is taken to cover in use, mouth times is pulled in the two sides of spanner
It is located on bolt, convenient for directly operating, is set on bolt without fixed side of choosing, improves service efficiency.
For this case disclosure of that, need to illustrate there are also the following:
(1), this case the disclosed embodiments attached drawing relate only to structure involved by this case disclosed embodiment,
His structure, which can refer to, to be commonly designed；
(2), in the absence of conflict, the feature in this case the disclosed embodiments and embodiment can be combined with each other with
Obtain new embodiment；
More than, only specific embodiment disclosed in this case, but the protection scope of the disclosure is not limited thereto, this case
Disclosed protection scope should be subject to the protection scope in claims.
