Description

Non-polar sleeve

Technical field

The utility model relates to a kind of box spanner, relates in particular to a kind of non-polar sleeve.

Background technology

Box spanner is called for short sleeve, by the sleeve in a plurality of band hexagon rings or 12 jiaos of holes and be furnished with multiple annexes such as handle, extension bar and form, is specially adapted to twist status ten minutes narrow and small or cave in the very bolt or the nut of depths.

Though the sleeve concave shape is the same; But external diameter, length etc. are the shape and size that are directed against corresponding device to be designed; Box spanner generally all have one overlap all size collet head be inserted in the nut of different size, so box spanner normally uses boxed 20 one boxes of lilliput socket spanner.

In use, need carry whole box box spanner, and, need change the sleeve of corresponding specification again, comparatively bother during use, bring big inconvenience to operating personnel for different big or small nuts.

The utility model content

The utility model is exactly that a kind of non-polar sleeve that can adaptive multiple different size nut is provided in order to solve the problem that above-mentioned prior art exists.

The purpose of the utility model realizes through following technical scheme:

A kind of non-polar sleeve comprises:

One pipe pawl;

One movable claw is positioned at said pipe pawl, connects with this pipe pawl pivot and forms the Flexible spanner mouth;

One first elastic component is located between this pipe pawl and the movable claw front, and this Flexible spanner mouth is opened;

One wedge shape pushing block is arranged between this pipe pawl and the movable claw back side, and said pipe pawl top is provided with a contiguous block, and one second elastic component is set between this contiguous block and the wedge shape pushing block, and this Flexible spanner mouth is dwindled;

Offer guide groove on the said pipe pawl, on the said wedge shape pushing block shifting block is set, this shifting block protrudes from guide groove outer guide groove and slides.

Preferably, said pipe pawl is the hexagonal pipe, and a cornicult of hexagonal pipe goes out to become a pawl.

Preferably, said first elastic component is a torsion spring, this torsion spring one end tube connector pawl, and the other end connects movable claw.

Preferably, said second elastic component is a stage clip, and this stage clip one end connects contiguous block, and the other end connects the wedge shape pushing block.

Preferably, said shifting block and wedge shape pushing block are one-body molded, or for passing the wedge shape pushing block, protruding from the outer steel pin of guide groove.

Preferably, said contiguous block external handle.

Preferably, said non-polar sleeve also comprises the button release that connects shifting block, drives the shifting block slip, and this button release is positioned at the pipe pawl outside.

Compared with prior art, the utlity model has following beneficial effect:

The non-polar sleeve of the utility model is pulled mouth through what the pipe pawl cooperated with movable claw that formation can magnify or dwindle; Regulate as required and pull a mouthful size; Nut that can the multiple model of adaptive clamping, a sleeve of the utility model can substitute the sleeve of one group of different size, uses, easy to carry.

The sleeve pipe sizing of the utility model is less, and the paw sizes of pipe pawl and movable claw can be thickeied, and has guaranteed the intensity of sleeve, and the utility model is simple in structure, pulls mouthful to regulate flexiblely, is easy to assemble, and helps reducing cost.

The specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing.

As a preferred embodiment of the utility model, shown in Fig. 1-3, a kind of non-polar sleeve comprises:

One pipe pawl 1, pipe pawl 1 is the hexagonal pipe, a cornicult of hexagonal pipe goes out to become a pawl;

One movable claw 2 is positioned at pipe pawl 1, articulates through pin 4 with this pipe pawl 1, and pipe pawl 1 forms the Flexible spanner mouth with the claw of movable claw 2, is used for ccontaining nut;

One torsion spring 3 is located between the front of pipe pawl 1 and movable claw 2, and pin 4 passes torsion spring 3, torsion spring 3 one end tube connector pawls 1, and the other end connects movable claw 2, and the Flexible spanner mouth that torsion spring 3 forms pipe pawl 1 and movable claw 2 keeps opening;

One wedge shape pushing block 5 is arranged between the back side of pipe pawl 1 and movable claw 2; This wedge shape pushing block 5 and movable claw 2 join through wedge principle; The top of pipe pawl 1 is provided with a contiguous block 7; Be provided with a stage clip 6 between this contiguous block 7 and the wedge shape pushing block 5, these stage clip 6 two ends are placed in respectively in the shrinkage pool on contiguous block 7 and the wedge shape pushing block 5.6 pairs of wedge shape pushing block 5 application of forces of stage clip, wedge shape pushing block 5 moves down activity compression pawl 2, and movable claw 2 and the Flexible spanner mouth that pipe pawl 1 forms are dwindled;

Offer guide groove 11 on the pipe pawl 1, on the wedge shape pushing block 5 shifting block is set, in the present embodiment, this shifting block is to pass wedge shape pushing block 5 and protrude from the steel pin 8 outside the guide groove 11, and the two ends of this steel pin 8 protrude from outside the guide groove 11 and can reciprocatingly slide along guide groove 11.

In the specific embodiment, the shifting block on the wedge shape pushing block also can be one-body molded with the wedge shape pushing block, protrudes from outside the guide groove.

Preferably; Non-polar sleeve also comprises button release 9; This button release connects shifting block, can drive the shifting block slip, and in the present embodiment, this button release 9 is for being sheathed on the outer teething ring of pipe pawl; This button release 9 is connected, can drives steel pin 8 with the two ends of steel pin 8 and reciprocatingly slides along guide groove 11, and and then promotion wedge shape pushing block 5 slips.

Preferably, but on contiguous block 7 external handle, be convenient to rotate this non-polar sleeve.

In original state, the Flexible spanner mouth keeps minimum state under the effect of stage clip, see Fig. 4, during use; Up lift button release with finger, shifting block drives on the wedge shape pushing block and moves compression press spring, the releasing activity pawl, and movable claw is opened under the effect of torsion spring; Pull a mouthful increase, can reach Flexible spanner mouth maximum rating, see Fig. 5; The Flexible spanner mouth grasps the nut rotation, and stage clip makes the wedge shape pushing block keep pressed status, guarantees to pull the pressure of pawl when the clamping nut.After the completion, unclamp nut, under the effect of stage clip, the wedge shape pushing block moves down and promotes movable claw and moves, and makes the Flexible spanner mouth closed, and the Flexible spanner mouth returns to minimum state.Utilize moving of wedge shape pushing block, make movable claw move folding, can reach the size of required nut.

More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
