Abstract

The utility model relates to an improved collet. A slotted hole for clamping a nut or a screwdriver rod is formed in the collet. The collet can clamp the nuts of different specifications and can clamp the screwdriver rod of different specifications, so that a socket wrench can retain the original functions and can also have a function of serving as the screwdriver. By adoption of the collet, the socket wrench can be integrated with the screwdriver, so various tools are not required to be carried, the phenomenon that the tools are exchanged frequently during operation is avoided, operation and use are facilitated greatly, and cost is saved.

Description

A kind of improved collet

Technical field

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

Background technology

Box spanner is by sleeve and be furnished with multiple annexes such as handle, extension bar and form, and is specially adapted to twist status very narrow and small or cave in the very bolt or the nut of depths.The general sleeve of all having a cover all size of box spanner is dealt with the nut of different size, during use, according to the nuts of different sizes, needs the sleeve of the corresponding specification of replacing, comparatively trouble.Non-polar sleeve cooperates through sleeve body and collet; Formation can magnify or dwindle pulls mouth, regulates as required and pulls a mouthful size, nut that can the multiple model of adaptive clamping; A non-polar sleeve can substitute the sleeve of one group of different size, uses, carries all very convenient.

But in operating personnel's the course of work, need the instrument of use a lot,, also have the most frequently used screwdriver except spanner.Normally used combined screwdriver all is the driver bit that a screwdriver handle disposes a plurality of different models and function simultaneously, according to the screw that will twist, change the driver bit (clamping screwdriver rod) of corresponding specification.Therefore, operating personnel also need carry combined screwdriver except carrying box spanner, both take up room, and gain in weight, and the frequent change instrument also brings inconvenience during operation.

The utility model content

The utility model is exactly for the problem that solves above-mentioned prior art existence a kind of improved collet to be provided, and can box spanner and screwdriver tool be united two into one through this collet, greatly facilitates operation and use.

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

A kind of improved collet is provided for the slotted eye of clamping nut or clamping screwdriver rod in the said chuck.

Preferably, said chuck comprises upper jaw and lower jaw, and the said slotted eye of the common composition of upper jaw and lower jaw is used for clamping nut or screwdriver rod.

Preferably, said upper jaw and lower jaw inboard are provided with step-like groove respectively, and the inboard said slotted eye of the common composition of step-like groove of upper jaw and lower jaw is used for clamping nut or screwdriver rod.

Preferably, said slotted eye is rearranged by the multistage through hole in different apertures continuously.

Preferably, said multistage through hole is step-like arrangement from outside to inside successively according to the aperture is descending.

Preferably, said multistage through hole is an arranged in co-axial alignment.

Preferably, in the said multistage through hole at least the one-level through hole be hexagonal configuration.

Preferably, the through hole of said hexagonal configuration is the equilateral hexagon shape.

Preferably, shape of through holes at different levels are identical or different in the said multistage through hole, said through hole be shaped as hexagon, octagonal, dodecagon, circle or tetragonal.

Preferably, said upper jaw and lower jaw are symmetrical structure.

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

The collet of the utility model can either the clamping different size nut again can the clamping different size screwdriver rod, make box spanner outside keeping original function, increased the function of using as screwdriver again.Can box spanner and screwdriver tool be united two into one through this collet, neither need carry multiple instrument, frequent change instrument when having avoided operation again greatly facilitates operation and use, also saves cost.

The specific embodiment

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

A box spanner generally includes sleeve assembly, connecting portion and handle, and sleeve assembly comprises the sleeve body of collet, connector and peripheral hardware usually.

Be illustrated in figure 1 as a preferred embodiment of the utility model, improved collet 100, the slotted eye 10 that settings not only can be used for the clamping nut but also can be used for the clamping screwdriver rod in this chuck 100.Concrete; This collet 100 comprises upper jaw 110 and lower jaw 120; Upper jaw 110 is arranged in connector 200 1 ends with a round pin respectively with lower jaw 120 and can rotates up and down, and upper jaw 110 and lower jaw 120 common compositions not only can be used for the clamping nut but also can be used for the slotted eye 10 of clamping screwdriver rod.

Further; Upper jaw 110 is a symmetrical structure with lower jaw 120; Shown in Fig. 2-3, upper jaw 110 is provided with step-like groove 130 respectively with lower jaw 120 inboards, and upper jaw 110 combines with lower jaw 120 inboard step-like grooves 130; Common formation not only can be used for the clamping nut but also can be used for the slotted eye 10 of clamping screwdriver rod, saw Fig. 4.

Concrete, slotted eye is rearranged by the multistage through hole in different apertures continuously, and this multistage through hole is step-like arrangement from outside to inside successively according to the aperture is descending, and this multistage through hole is an arranged in co-axial alignment.

Shape of through holes at different levels can be identical or different in this multistage through hole, the preferred hexagon of the shape of through hole, octagonal, dodecagon, circle or tetragonal, and to have the one-level through hole in this multistage through hole at least be hexagonal configuration or equilateral hexagon shape.

In the present embodiment; Slotted eye 10 is step-like arranged in co-axial alignment from outside to inside successively and forms according to the aperture is descending by the two-stage through hole in different apertures; The aperture of one-level through hole is greater than the aperture of secondary through holes; The one-level through hole is identical with the shape of secondary through holes, all is hexagonal configuration, and secondary through holes is the equilateral hexagon shape.

During use; This collet not only can the clamping different size nut but also screwdriver rod that can the clamping different size; Make box spanner both keep the former function that is used as the box spanner clamping, twists nut; Can be used as the hex(agonal)screw cutter head of screwdriver handle clamping different size again, increased the function of using as screwdriver.Can box spanner and screwdriver tool be united two into one through this collet, neither need carry multiple instrument, frequent change instrument when having avoided operation again greatly facilitates operation and use, also saves cost.

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.
