Abstract
The utility model discloses a butterfly nut special spanner, including the sleeve, this telescopic internal diameter is greater than butterfly nut's external diameter, and this telescopic bottom is equipped with two draw -in grooves of relative setting, puts butterfly nut's butterfly ears through this two draw -in grooves card, still include two twist grips, telescopic radial rigid coupling in sleeve outer wall is followed respectively to this two twist grip, and the coaxial setting of this two twist grip. The utility model discloses only need during the operation will overlap the barrel casing outside butterfly nut to the butterfly ears that make butterfly nut block respectively in two draw -in groove departments, the even rotatory rotate handle sleeve of rethread can, very convenient, butterfly nut's butterfly ears deformation and damage can also be avoided to single can the operation, and not only can effectively screw up butterfly nut. Furthermore, telescopic radial rigid coupling in sleeve is followed respectively to two twist grips, can avoid the twist grip to lose on the one hand, when on the other hand can make the user pass through rotatory rotate handle sleeve, avoids the twist grip positioning and influences the operation.
Description
Technical field
This utility model relates to a kind of spanner, particularly relates to a kind of wing nut special spanner.
Background technology
During the operations such as, dismounting ground wire built-in in transformer station, in order to reduce the resistance in earth lead loop as far as possible, it is necessary to increase the locking pressure between wing nut and earth lead, Earth pile-head as far as possible.Special construction due to wing nut, common spanner or pliers effectively cannot be exerted a force on the butterfly ears of wing nut simultaneously, and generally require two people carry out tacit agreement compounding practice could realize, and the butterfly ears intensity of wing nut is relatively low, unbalance stress often leads to the butterfly ears deformation of wing nut or damages, and the butterfly ears of wing nut are once damage and taking off wing nut and comparatively waste time and energy again.
Utility model content
This utility model provides a kind of wing nut special spanner, for solving the problem that wing nut is not easy operation, butterfly ears are easily deformed damage.
This utility model solves its technical problem and be the technical scheme is that a kind of wing nut special spanner, including sleeve, the internal diameter of this sleeve is more than the external diameter of wing nut, and the bottom of this sleeve is provided with two draw-in grooves being oppositely arranged, by the butterfly ears of this two draw-in grooves holding wing nut；Also including two rotary handles, this two rotary handle is fixed in sleeve outer wall along the radial direction of sleeve respectively, and this two rotary handle is coaxially disposed.
As further improvement, the free end of described two rotary handles has been respectively and fixedly connected with bulb.
As further improvement, described two rotary handles are respectively equipped with anti-skidding striped.
As further improvement, the length of described draw-in groove is 25～35mm.
As further improvement, the width of described draw-in groove is 5～10mm.
As further improvement, the internal diameter of described sleeve is 20～30mm, and the external diameter of described sleeve is 30～35mm, and the length of described sleeve is 90～110mm.
As further improvement, described two rotary handles are respectively welded in described sleeve.
As further improvement, the diameter respectively 15～18mm of described two rotary handles, the distance between the centre of sphere of the bulb on described two rotary handles is 180～220mm.
Compared to prior art, this utility model has the advantages that
This utility model is by arranging described sleeve and two draw-in grooves thereon, two rotary handles, when making mounting or dismounting wing nut, only need to sleeve be enclosed within outside wing nut, and make the butterfly ears of wing nut be stuck in two draw-in groove places, again through even rotary handle rotational sleeve, very convenient, single namely operable, and it is possible not only to effectively tighten wing nut, it is also possible to avoid the butterfly ears deformed damaged of wing nut.Additionally, described two rotary handles are fixed in sleeve along the radial direction of sleeve respectively, rotary handle can be avoided to lose on the one hand, when another aspect can make user pass through rotary handle rotational sleeve, it is to avoid rotary handle positioning and affect operation.
Below in conjunction with drawings and Examples, this utility model is described in further detail；But a kind of wing nut special spanner of the present utility model is not limited to embodiment.
Accompanying drawing explanation
Fig. 1 is D structure schematic diagram of the present utility model；
Fig. 2 is front view of the present utility model.
Detailed description of the invention
Embodiment, refer to shown in Fig. 1, Fig. 2, a kind of wing nut special spanner of the present utility model, including sleeve 1, the cross section of this sleeve 1 is annular, the internal diameter of this sleeve 1 is more than the external diameter of wing nut, and the bottom of this sleeve 1 is provided with two draw-in grooves 11 being oppositely arranged, by the butterfly ears of this two draw-in groove 11 holding wing nut；Also including two rotary handles 2, this two rotary handle 2 is fixed in the top exterior walls of sleeve 1 respectively along the radial direction of sleeve 1, and this two rotary handle 2 is coaxially disposed.
In the present embodiment, the free end of described two rotary handles 2 is respectively welded the bulb 3 that diameter is 35mm, the setting of this bulb 3, it is possible to strengthen the operating handle of this wing nut special spanner.
In the present embodiment, the length respectively 25～35mm of described two draw-in grooves 11, it is specially 30mm, the width respectively 5～10mm of described two draw-in grooves 11, is specially 8mm.
In the present embodiment, the internal diameter of described sleeve 1 is 20～30mm, is specially 26mm, and the external diameter of described sleeve 1 is 30～35mm, is specially 32mm, and the length of described sleeve 1 is 90～110mm, is specially 100mm.
In the present embodiment, described two rotary handles 2 are respectively welded in described sleeve 1, and two diameter respectively 15～18mm of rotary handle 2, it is specially 16mm, distance between the centre of sphere of the bulb 3 on this two rotary handle 2 is 180～220mm, being specially 200mm, the axis of described two rotary handles 2 is 85mm to the distance of sleeve 1 bottom.
During work, sleeve 1 is enclosed within outside wing nut, and makes the butterfly ears of wing nut be stuck in two draw-in groove 11 places of sleeve 1, then, rotate two rotary handles 2, tightening or unscrewing of wing nut can be realized.In fastener cycle, two draw-in grooves 11 of sleeve 1 contact with the root of the butterfly ears of wing nut respectively, and therefore, the moment of torsion that the butterfly ears of wing nut bear is obviously reduced, it is possible to avoid butterfly ears to deform.
In other embodiments, described two rotary handles are respectively equipped with anti-skidding striped.
Above-described embodiment is only used for further illustrating a kind of wing nut special spanner of the present utility model; but this utility model is not limited to embodiment; every any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, each falls within the protection domain of technical solutions of the utility model.
