Description

Combined type inner hexagonal wrench

Technical Field

The utility model relates to an inner hexagonal wrench, in particular to a combined inner hexagonal wrench.

Background

More and more of hexagon socket head cap screw is used in people's life and production, the event spanner that is used for fastening hexagon socket head cap screw then has more and more application scenario, but current hexagon socket head cap screw is the solitary individual hexagonal prism more, because its individuality is less, the model is more, and every model can only be operated to the bolt of a specification, consequently will bring inconvenience for operating personnel when using hexagon socket head cap screw inspection maintenance different specification size's bolt, and current hexagon socket head cap screw generally does not have the protective sheath structure, so, the long-time exposure of hexagon socket head cap screw has also increased the risk of wearing and tearing or colliding with outward, thereby greatly reduced its life and smooth and easy degree of use.

Therefore, a combined type inner hexagonal wrench which has a better protection effect, can be combined and used, and is convenient and labor-saving is urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a combined type inner hexagonal wrench which has a good protection effect, can be combined and used, and is trouble-saving and convenient to use.

The utility model provides the following technical scheme:

the utility model provides a modular interior hexagonal spanner, including the overcoat and be located at least two sets of outside-in of overcoat cover in order and establish complex interior hexagonal spanner head, the one end of overcoat is equipped with the shrouding, the top of each interior hexagonal spanner head all is fixed with a gag lever post, the cooperation setting is established for outside-in cover in order to the multiunit gag lever post, and outermost gag lever post stretches out the shrouding setting, the tip of gag lever post still is connected with stop nut, stop nut butt on the outermost gag lever post is spacing on the shrouding, and other stop nut then the butt at the outer gag lever post tip of the gag lever post of connecting.

Preferably, three groups of inner hexagonal wrench heads which are sequentially sleeved from outside to inside are arranged in the outer sleeve.

Preferably, the limiting rod is further sleeved with a compression spring, two ends of the compression spring outside the outermost limiting rod are abutted to the end portions of the sealing plate and the inner hexagonal wrench head, and two ends of the compression spring outside other limiting rods are respectively abutted to the groove holes of the inner hexagonal wrench head and the end portions of the outer end portions of the inner hexagonal wrench head on the inner layer.

Preferably, the outer sleeve and the inner hexagonal wrench head are internally provided with longitudinal sliding grooves, and one end of the inner hexagonal wrench head is also provided with a sliding block which is in sliding fit with the outer sleeve or the inner hexagonal wrench head.

Preferably, the jacket circumferential side wall is cylindrical.

The utility model has the beneficial effects that: before using, the hexagon socket head spanner is in stretching into the overcoat or its outer hexagon socket head spanner of nexine, and realize the location of hexagon socket head spanner through stop nut, thereby on guaranteeing that the hexagon socket head spanner can make up the basis of using, can also ensure that each hexagon socket head spanner can both have better protective effect, and when using the hexagon socket head spanner of a model, only need to twist the stop nut who corresponds on the gag lever post soon, the hexagon socket head spanner that will correspond pops out in the hexagon socket head spanner of its outer layer or the overcoat can, it is convenient comparatively for saving trouble, and can ensure that the hexagon socket head spanner of other models still is in protective range.

Drawings

The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the principles of the utility model and not to limit the utility model. In the drawings:

FIG. 1 is a structural cross-sectional view of the present invention;

FIG. 2 is a sectional view of the structure of the hexagonal wrench head in the outermost layer when it is extended;

FIG. 3 is a sectional view of the second allen wrench head in the second position;

notation in the figure: the wrench comprises a shell 1, a hexagon socket wrench head 2, a sealing plate 3, a limiting rod 4, a limiting nut 5, a compression spring 6, a longitudinal sliding groove 7 and a sliding block 8.

Detailed Description

Combine a modular allen key shown in fig. 1-3, in this embodiment, including overcoat 1 and at least two sets of outside-in that are located overcoat 1 in the cover overlap in order and establish complex allen key 2, the one end of overcoat 1 is equipped with shrouding 3, the top of each inside key 2 all is fixed with a gag lever post 4, multiunit gag lever post 4 is the outside-in cooperation setting of establishing in order, and outermost gag lever post 4 stretches out shrouding 3 setting, the tip of gag lever post 4 still is connected with stop nut 5, stop nut 5 butt on outermost gag lever post 4 is spacing on shrouding 3, and other stop nut 5 then the butt is at the outer gag lever post 4 tip of gag lever post 4 that connects.

Three groups of inner hexagonal wrench heads 2 which are sequentially sleeved from outside to inside are arranged in the outer sleeve 1.

Still the cover is equipped with compression spring 6 outside

gag lever post

4, and 6 both ends butt of the outer compression spring of outermost gag lever post 4 are between 2 tip of shrouding 3 and hexagon socket head wrench head, and 6 both ends of the outer compression spring of other gag lever posts 4 butt respectively between hexagon socket head wrench head slotted hole and the inner hexagonal wrench head outer end tip of inlayer to after 5 back of unscrewing soon corresponding stop nut on the top gag lever post 4, the hexagon socket head wrench head that corresponds can be popped out automatically, and can fix a position.

Still be equipped with vertical spout 7 in overcoat 1 and the hexagon socket head wrench 2, the one end of hexagon socket head wrench still is equipped with rather than outer overcoat 1 or hexagon socket head wrench sliding fit's slider 8 to can confirm a pop-up length for hexagon socket head wrench 2, avoid hexagon socket head wrench head to stretch out length too big.

The circumferential side wall of the outer sleeve 1 is cylindrical.

The working principle of the utility model is as follows: before using, the hexagon socket head spanner is in stretching into overcoat 1 or the hexagon socket head spanner on its skin, and realize the location of hexagon socket head spanner through stop nut 5, thereby on guaranteeing that the hexagon socket head spanner can make up the basis of using, can also ensure that each hexagon socket head spanner can both have better protective effect, and when using the hexagon socket head spanner of a model, only need to twist stop nut 5 on corresponding gag lever post 4 soon, the hexagon socket head spanner that will correspond is popped out in from its outer hexagon socket head spanner or overcoat 1 can, and is comparatively convenient, and can ensure that the hexagon socket head spanner of other models is still in protective range.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
