Abstract
The utility model proposes a kind of chain type universal wrench, including chain, threaded sleeve, screwed pipe and movable head, described chain one end is connected with threaded sleeve, the other end through threaded sleeve and screwed pipe with and movable head be connected, the threaded sleeve is connected threadably with screwed pipe.Chain type universal wrench of the present utility model can mount and dismount to the connector of the nut of Multiple Type, bolt and other shapes.It is simple, easy to operate that the structure of operating efficiency and the invention can be improved, there is higher promotional value.
Description
Technical field
It the utility model is related to hardware ＆ tools field, and in particular to a kind of chain type universal wrench.
Background technology
Spanner is a kind of conventional hardware ＆ tools；Using lever principle, spanner can easily twist bolt, nut etc. even
Fitting；Mainly there are monkey wrench and inflexible hand through common spanner at present, monkey wrench can adjust the spacing of bayonet socket, Neng Gouying
For the nut to Multiple Type, bolt；Inflexible hand can be only applied to the consistent bolt or nut of model；But these spanners are only
The screw bolt and nut that outline is hexagon can be dealt with, and the occasion for having the nut of Multiple Type, bolt needs repeatedly
Change inflexible hand or repeatedly adjust monkey wrench, cause operating efficiency low；In addition, these spanners can be only applied to outline
On hexagon or the part on four sides, can not but to be operated for the connector of cylinder.
Utility model content
The utility model proposes a kind of chain type universal wrench, solve that spanner in the prior art is single, can not flexibly use
The problem of.
What the technical solution of the utility model was realized in：A kind of chain type universal wrench, including chain, threaded sleeve,
Screwed pipe and movable head, described chain one end is connected with threaded sleeve, the other end through threaded sleeve and screwed pipe and and is lived
Dynamic head is connected, and the threaded sleeve is connected threadably with screwed pipe.
The hollow setting of screwed pipe and threaded sleeve.
Described screwed pipe one end is placed in threaded sleeve, the other end is connected with movable head, and the size of movable head outline
More than the internal diameter of screwed pipe.
The chain is fixedly connected with threaded sleeve.
The internal diameter of the screwed pipe is more than the length of chain hinge pin.
The beneficial effects of the utility model are：Chain type universal wrench of the present utility model can to the nut of Multiple Type,
Bolt and the connector of other shapes are mounted and dismounted.The structure that can improve operating efficiency and the invention is simple,
It is easy to operate, there is higher promotional value.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is schematic diagram when universal spanner holds nut tightly.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is paid
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 1, the present embodiment is based on a kind of chain type universal wrench, it includes chain 1, threaded sleeve 2, screwed pipe 3
And movable head 4, the hollow setting of screwed pipe 3 and threaded sleeve 2.The one end of chain 1 is directly welded on threaded sleeve 2,
The other end is welded on movable head 4 through threaded sleeve 2 and screwed pipe 3, and threaded sleeve 2 and screwed pipe 3 are with the side of threaded connection
Formula is connected, and the internal diameter for being more than screwed pipe 3 located at the outside of screwed pipe 3 and the outer profile size of movable head 4 of movable head 4, makes
Chain 1 is enclosed on the connector of nut, bolt or other shapes by the used time, and the He of threaded sleeve 4 is adjusted by rotated threaded tubular 3
The overall length of screwed pipe 3, while screwed pipe 3 promotes movable head to be tensioned chain 1, and then chain 1 is held nut 5, bolt tightly
Or the connector of other shapes, as shown in Fig. 2 the chain 1 for holding workpiece portion tightly forms a polygon after bending, this
When promote the connectors of nut, bolt and other shapes can be just twisted at screwed pipe 3.
The chain 1 is connected with movable head 4, or is connected by middleware, and movable head 4 needs and screwed pipe 3
Be separation, if movable head 4 is connected with screwed pipe 3, screwed pipe 3 will not be stuck, this be due to chain 1 one end with
Sleeve pipe is connected, and chain 1 can only be bent in specific direction.The internal diameter of screwed pipe 3 needs the length more than chain hinge pin, prevents
Chain be stuck in pipe and can not smooth movement.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
