Abstract
The utility model belongs to hardware tool field, specifically discloses a kind of collet head of reducing.Multiple hexagonal screw rods and cavity are provided in collet head, screw rod one end is equipped with spring, half of screw may be collapsible into cavity under the effect of external force, the not contracted screw rod into cavity encloses sleeve wall, different bolts or nut can be such that the screw rod of different number shrinks as the variable diameter of collet head realized, after the completion of use in cavity, under the action of the spring, screw reset.Collet head disclosed by the utility model, structure is simply, it can be achieved that the variable diameter of collet head, reduces the collet head quantity of box spanner, use is easy to carry.
Description
[technical field]
The utility model belongs to hardware tool field, and in particular to a kind of collet head of reducing.
[background technique]
Box spanner is commonly used tool in machinery field, is broadly divided into handle, adapter and set according to its structure
Cylinder head.For the bolt and nut for adapting to different-diameter, a secondary box spanner is often equipped with the collet head of multiple and different models.Sleeve
Header structure is simple, small in size, inconvenient to carry, is easily lost.
[utility model content]
The purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of collet head of reducing, solve existing
There is in technology a secondary box spanner must be equipped with the collet head of multiple and different models, use is inconvenient to carry, and what is be easily lost asks
Topic.
Specifically, the technical solution of the utility model is:
A kind of reducing collet head, multiple hexagonal screw rods are provided in the collet head, and one end of hexagonal screw rod is cylinder
Shape, the other end are hexagon；In collet head, one end far from sleeve openings is equipped with corresponding with multiple hexagonal screw rod cylindrical ends
Circular cylindrical cavity, hexagonal screw rod cylindrical end installation in the cavity；The cylindrical end of hexagonal screw rod is cased with spring, spring
Diameter is less than the diameter of hexagonal screw rod hex end, greater than the diameter of circular cylindrical cavity, makes the cylindrical end of hexagonal screw rod can be
Stretching motion is done in cavity.
Further, the cylindrical end of the hexagonal screw rod is equipped with boss close to one end of cavity, and the diameter of boss is greater than
The diameter of hexagonal screw rod cylindrical end, less than the diameter of cavity；The cavity is close to one end of hexagonal screw rod, along the opening of cavity
Equipped with convex edge, the diameter of convex edge is greater than the diameter of hexagonal screw rod cylindrical end, less than the diameter of boss；Boss and convex edge cooperation,
In the cavity by the cylindrical end limitation of hexagonal screw rod.Further,
Compared with prior art, collet head disclosed by the utility model, setting can be in collet head in existing collet head
Interior flexible multiple hexagonal screw rods, part hexagonal screw rod is compressed into cavity by outer bolt or nut under external force when use
Interior, unpressed screw rod encloses collet head inner wall, the diameter of flexibly changing collet head, suitable for different-diameter screw rod or
Nut can make a secondary box spanner be equipped with less collet head, easy to carry, not easy to lose.
[Detailed description of the invention]
Fig. 1 is the perspective view of the utility model embodiment 1.
Fig. 2 is the cross-sectional view of Fig. 1.
Fig. 3 is the cross-sectional view under Fig. 1 use state.
It is as follows that corresponding structure is numbered in figure:
1, collet head 1-1, cavity 1-11, convex edge 2, hexagonal screw rod 2-1, hex end 2-2, cylindrical end 2-
21, boss.
[specific embodiment]
Clear and complete description is carried out to the technical solution of the utility model below in conjunction with attached drawing.Obviously, described
Embodiment is a part of the embodiment of the utility model, instead of all the embodiments.Based on the embodiments of the present invention, originally
The those of ordinary skill in field other embodiments obtained without making creative work belong to practical
Novel protection scope.
Embodiment 1: referring to Fig.1-3:
A kind of reducing collet head, one end far from opening in collet head 1 are provided with multiple circular cylindrical cavity 1-1, cylinder
The opening of shape cavity 1-1 is equipped with convex edge 1-11 along the opening of cavity 1-1.Hexagonal screw rod 2, hexagonal screw rod 2 are equipped in collet head 1
One end be hexagonal hex end 2-1, the other end is cylindrical circumferential end 2-2, is cased with spring on cylindrical end 2-2
3, cylindrical end 2-2 is mounted in cavity 1-1, and the one end of cylindrical end 2-2 in cavity 1-1 is equipped with boss 2-21, boss 2-
21 diameter is greater than the diameter of convex edge 1-11, and cylindrical end 2-2 is limited in cavity 1-1.The diameter of spring 3 is greater than convex edge 1-
1 diameter, less than the diameter of hex end 2-1, spring 3 is arranged between cavity 1-1 and hex end 2-1, can make retraction chamber
Cylindrical end 2-2 in body 1-1 pops up cavity.
In actual use, firmly by 1 set of collet head on bolt or nut, stop bolt or nut under the effect of external force
2 retraction cavity 1-1 of hexagonal screw rod in, the hexagonal screw rod in non-retraction cavity 1-1 surrounds sleeve wall, the bolt of different-diameter or
Nut can realize the variable diameter of set sketch drawing in different amounts of hexagonal screw rod retraction cavity 1-1.After the completion of use, in the effect of spring 3
Under, the screw reset in retraction cavity 1-1 pops up cavity 1-1.
Above-described embodiment is merely to illustrate the technical solution of the utility model, rather than its limitations.The utility model is not
It is confined to be described above and the accurate structural illustrated in the accompanying drawings is, and it cannot be said that the specific implementation of the utility model is only limited to
In these explanations.For the utility model person of an ordinary skill in the technical field, the utility model structure is not being departed from
Under the premise of think of, the various changes and variants made all shall be regarded as belonging to the protection scope of the utility model.
