Abstract
The utility model discloses a fixing tool disc spiral organ of a screw thread connection device. The handle of the spiral organ is of disc shape, which is a coaxial body molded by plastic together with a jacket and a sleeve arranged on the jacket. As the handle is of disc shape, the spiral organ occupies small space when turning the handle, and the bolt receives even force, compared with the unilateral rotary spanner, the bolt is not influenced by bending moment, thereby reducing the possibilities of bolt ruptures. The handle, the jacket and the sleeve are integrated together by injection molding with simple structure, convenient machining and low cost.

As preferably, urceolus is column, and the upper end links to each other with handle, and the diameter of urceolus is littler than the diameter of handle, and the central shaft upper end is provided with cylindrical cavity.The effect of cavity is when clamp nut, reserves certain position and holds the bolt that exceeds nut.
As preferably, sleeve is positioned at the lower end of urceolus, the lower end of sleeve is concordant with the lower end of urceolus, inside is provided with the polygon cavity, and the cross section of polygon cavity is that a regular polygon or a regular polygon add concentric placement of another same regular polygon that rotates a certain angle and the outward flange shape of formation.The shape of cross section of polygon cavity is pressed the nut style and is decided, and one of them that is preferably positive triangle, square, regular pentagon, regular hexagon or they adds that another same regular polygon that rotates a certain angle is placed with one heart and the outward flange shape that forms.
As preferably, the core of handle is an entity structure, and the upper end of entity structure and urceolus is connected, and the edge of handle is provided with several along the equally distributed dentalation of circumference.The core of handle is made entity structure, is to consider to stop long bolt from middle the passing of handle palm to be damaged.The dentalation at edge can increase frictional force, handled easily.
As preferably, sleeve is a metal material, and the lateral surface of sleeve is a male and fomale(M﹠F), and male and fomale(M﹠F) and urceolus closely cooperate.Sleeve adopts metal material, has improved the intensity of spiral organ damageable zone, has prolonged service life.
As preferably, there is an enclosed construction upper end of sleeve, and a circular hole is arranged on the enclosed construction, the upper end of circular hole links to each other with the cylindrical cavity of urceolus central shaft upper end, the lower end links to each other with the polygon cavity, and the diameter of circular hole is identical with the diameter of cylindrical cavity, central axes.The diameter of circular hole is identical with the diameter of cylindrical cavity, and the one, make things convenient for the turnover of bolt, the 2nd, add and be convenient in demoulding man-hour.
As preferably, the outside of handle is circular, between some entity structures that are distributed in the annulus in the handle outside and center along the evenly distributed disc of circumference, the thickness of disc and the consistency of thickness of entity structure, less than the thickness of annulus, adopt arc transition to connect between the both sides of disc and annulus and the entity structure.Web pattern is set on handle, can economical with materials, reduce cost, also can alleviate the weight of spiral organ simultaneously.Adopt arc transition to connect between the both sides of disc and annulus and the entity structure, can increase the intensity of spiral organ handle.
As preferably, the upper end of cylindrical cavity is a pyramidal structure, and the vertex of a cone of pyramidal structure links to each other with the entity structure of handle core.The effect of pyramidal structure is an intensity of strengthening entity structure, and fully dispersive stress prevents the long damage entity structure of bolt.
As preferably, handle and urceolus are the suitable plastic material of hard and rigidity, all adopt arc transition between any of its outer surface and the face.Arc surface can not cause actual bodily harm to the user, makes the profile of disc type spiral organ more attractive in appearance simultaneously.
The beneficial effects of the utility model are: it has solved skid the easily problem of damage, bolt strained excessive easy fracture of nut in the present screw connection assembling process effectively, and it is little to take up room during work, simple in structure, convenient for production, with low cost.
