Abstract

The utility model relates to a hex wrench, which comprises a rod-shaped working end provided with six equally divided propping surfaces, and more than one propping surface is provided with a groove on the part adjacent to the connected edge corner, so as to enable the edge corners to be occluded with the abraded inner wall surfaces of the accommodating grooves for hexagon socket head cap screws to achieve the purposes of close-propping force application, little possibility of slippage, and excellent force application efficiency, and therefore the utility model is extremely convenient and practical.

Description

Die nut

Technical field

The utility model relates to a kind of hand-held tool, refers in particular to a kind of die nut.

Background technology

When the die nut of prior art inserts the storage tank of hexagon socket head cap screw with the working end at present,, can cause the internal face wearing and tearing of the storage tank of hexagon socket head cap screw owing to rotate the application of force often; And make the working end positively be tight against the application of force with the storage tank internal face, cause the working end easily skid and user's application of force efficient not good.

Therefore, after storage tank internal face wearing and tearing, the die nut of prior art can't be tight against the application of force really, has that easily skid in the working end and the not good problem of user's application of force efficient, and necessity of improvement is arranged in fact.

The utility model content

The purpose of this utility model is to provide a kind of die nut, it is concaved with groove on the face of supporting, make the storage tank internal face after the edges and corners interlock is worn and torn, reach and be tight against the application of force really, be difficult for skidding and purpose that application of force efficient is good, with the die nut that solves prior art after the wearing and tearing of storage tank internal face, relevant for being tight against deficiency and the restriction that easily skid in the application of force, working end and user's application of force efficient is not good really.

For achieving the above object, the die nut that the utility model provides comprises: a working end, and it is shaft-like and is provided with an operative end surface and the face that supports of six five equilibriums; These six are supported more than one in the face to support face are in being concaved with a groove in abutting connection with the corner angle that join, and this more than one groove runs through this operative end surface.

Described die nut supports three in the face faces that support that are provided with at interval and respectively has two grooves.

Described die nut, the face of supporting respectively has a groove, and each groove is positioned at corresponding the same side of supporting face.

Described die nut, the face that supports that is positioned at two opposite sides that supports in the face respectively has a groove, and each groove is positioned at corresponding the same side of supporting face.

Die nut provided by the utility model, concrete benefit that can obtain and effect are promoted: application of force efficient is good, the utility model is concaved with groove on the face of supporting, make the storage tank internal face after the edges and corners interlock is worn and torn, reach and be tight against the application of force really, be difficult for skidding and purpose that application of force efficient is good, very convenient and practical.

The specific embodiment

Following conjunction with figs. and preferred embodiment of the present utility model, further setting forth the utility model is to reach the technological means that predetermined utility model purpose is taked.

First preferred embodiment of a kind of die nut provided by the utility model, shown in Fig. 1 to 3, this die nut is L-shaped and comprise a working end 10, wherein:

Shown in Fig. 1,3,4, this working end 10 is shaft-like and can be inserted in the storage tank A1 of a hexagon socket head cap screw A, and this working end 10 is provided with the face 12 that supports of an operative end surface 11 and six five equilibriums; This operative end surface 11 is a plane; These six the more than one faces 12 that support that support in the face 12 are in being concaved with a groove 121 in abutting connection with the corner angle Q that joins, this more than one groove 121 is microscler and extends along the straight line that is parallel to these working end 10 axis, and this more than one groove 121 runs through this operative end surface 11; Preferably, the cross sectional shape of each groove 121 is a triangle.

In first preferred embodiment of the present utility model, the quantity of this more than one groove 121 is six; These six faces 12 that support that support three interval settings in the face 12 respectively have two grooves 121; Thus, can be in the working end 10 clockwise or when being rotated counterclockwise, but interlock storage tank A1 internal perisporiums all;

Please further referring to Fig. 4, the storage tank A1 of hexagon socket head cap screw A is inserted in working end 10, and edges and corners interlock storage tank A1 internal face, can reach to be tight against the application of force really, to be difficult for skidding and purpose that application of force efficient is good.

As shown in Figure 5, in second preferred embodiment of the present utility model, the quantity of this more than one groove 121 is six; These six are supported face 12 and respectively have a groove 121; Each groove 121 is positioned at corresponding the same side of supporting face 12, and promptly the groove 121 in second preferred embodiment is positioned at same direction of rotation (watching with operative end surface 11, then is counterclockwise).

As shown in Figure 6, in the 3rd preferred embodiment of the present utility model, the quantity of this more than one groove 121 is two; These six faces 12 that support that are positioned at two opposite sides that support in the face 12 respectively have a groove 121, and each groove 121 is positioned at corresponding the same side of supporting face 12.

As shown in Figure 7, in the 4th preferred embodiment of the present utility model, the quantity of this more than one groove 121 is one.

In the utility model, if the internal face that the edges and corners that join can interlock storage tank A1, about the quantity and the arrangement mode of groove 121, the neither specific limited of doing of the utility model.

The above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, those skilled in the art are in the scope that does not break away from technical solutions of the utility model, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
