Abstract

The utility model relates to a scalable double -end sleeve, including sleeve pole and one big one little two sleeve barrel opening s of fixed connection at sleeve pole both ends, the sleeve pole is fully adjustable's telescopic link, regular hexagon linking machine and square pulling hole have all been seted up to every sleeve barrel opening middle part, the regular hexagon linking machine size of big sleeve barrel opening hole one end is greater than the regular hexagon linking machine of little sleeve barrel opening one end. The utility model discloses a scalable double -end sleeve, it is applicable in the hexagon nut of two kinds of sizes, compact structure, it is simple to use, effective cost of practicing thrift, and sleeve pole fully adjustable, thus can screw up or unscrew the screw that is in different depth position through the length of adjusting sleeve pole, effectively reduced the quantity of the required screwdriver that carries of constructor, not only can reduce use cost, can reduce constructor's intensity of labour moreover, be favorable to improving work efficiency.

Description

A kind of Telescopic double-head sleeve

Technical field

This utility model is related to a kind of adapter tool, more particularly to a kind of Telescopic double-head sleeve.

Background technology

Sleeve is a kind of instrument, and which is mainly used for being sleeved on screw rod, is used for a kind of instrument tightened, unscrew on nut, With easy to use, the characteristics of easy to use.Commercially the looping of ordinary cartridge is usually regular polygon, when in use, It is applied object (such as nut) to match with its angle position, this generates the limitation that ordinary cartridge is used to a certain extent Property；In addition, the structure of sleeve widely used in production and life is typically all fixed at present, it is impossible to by adjustment length So as to the screw in different depth position is tightened or unscrewed, result in the need for workmen and carry various different lengths The sleeve of specification could be tightened or be unscrewed to the screw in different depth position, therefore, it is a kind of in the urgent need to developing It is capable of the sleeve of adjustment length.

Utility model content

This utility model purpose is to propose a kind of simple structure to overcome the deficiencies in the prior art, easy to use Telescopic double-head sleeve.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is：A kind of Telescopic double-head sleeve, including sleeve Bar and small one and large one two sleeve-ports for being fixedly connected on socket bar two ends；Expansion link of the socket bar for adjustable in length； Regular hexagon linking machine is offered in the middle part of described each sleeve-port and square pulls hole；Described big sleeve oral pore one end is just Regular hexagon linking machine of the hexagon linking machine size more than small sleeve mouth one end.

Preferably, the socket bar includes flexible interior bar and fixed outer bar, and the flexible interior bar is slidably set in fixation In outer bar, and fixed outer bar is provided with adjusting screw, and the adjusting screw is used for the position of fixed flexible interior bar.

Preferably, to pull hole equivalently-sized for described two squares.

Preferably, the outer wall of the fixed outer bar is provided with annular knurl.

Preferably, the socket bar is multiple field extension sleeve, including multiple flexible interior bars and fixed outer bar.

Preferably, six reinforcements are uniformly provided with the excircle of each sleeve-port；The position of each reinforcement On center extension line setting in each corner of regular hexagon linking machine.

Due to the utilization of above-mentioned technical proposal, this utility model has following advantages compared with prior art：

Telescopic double-head sleeve of the present utility model, is applicable to the hex nut of two kinds of sizes, and compact conformation, using letter Single, effectively save cost, and socket bar adjustable in length, can be by the length of adjusting set cylinder bar so as to in different deep The screw of degree position is tightened or is unscrewed, and effectively reduces the quantity of the screwdriver carried required for workmen, not only Can reduce use cost, and the labor intensity of workmen can be reduced, be conducive to improving work efficiency.

In figure：1st, socket bar；11st, flexible interior bar；12nd, fixed outer bar；2nd, sleeve-port；3rd, regular hexagon linking machine；4th, just It is square to pull hole；5th, adjusting screw；6th, annular knurl；7th, reinforcement.

Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.

As shown in accompanying drawing 1-4, a kind of Telescopic double-head sleeve of the present utility model including socket bar 1 and is fixedly connected on Small one and large one two sleeve-ports 2 at socket bar two ends；Expansion link of the socket bar 1 for adjustable in length；Described each sleeve Regular hexagon linking machine 3 is all offered in the middle part of mouth 2 and square pulls hole 4；The regular hexagon set of described big sleeve oral pore one end Regular hexagon linking machine of the oral pore size more than small sleeve mouth one end；The socket bar 1 includes flexible interior bar 11 and fixed outer bar 12, the flexible interior bar 11 is slidably set in fixed outer bar 12, and fixed outer bar 12 is provided with adjusting screw 5, the tune Section screw 5 is used for the position of fixed flexible interior bar 11.

Further instruction, it is equivalently-sized that described two squares pull hole 4, therefore it may only be necessary to match somebody with somebody a spanner.

Further instruction, the outer wall of the fixed outer bar 12 are provided with annular knurl 6, annular knurl 6 can increase handss and sleeve it Between frictional force, it is convenient directly to use handss rotational sleeve.

Further instruction, the socket bar 1 are multiple field extension sleeve, including multiple flexible 11 interior bars and fixed outer bar 12, therefore Extensible is longer, using wider.

Further instruction, is uniformly provided with six reinforcements 7 on the excircle of each sleeve-port 2；It is described each add On the center extension line in each corner that the position of strong muscle 7 is located at regular hexagon linking machine 3, the design of reinforcement 7 causes corner Bigger counteracting force can be born, the situation of fracture is less prone to, is effectively extended the service life of sleeve.

When sleeve of the present utility model is used, according to being applied object（Such as the hex nut of matching size）Position adjustments Then the adaptor of spanner is plugged on and is pulled in hole by the length of socket bar, and regular hexagon running-on borehole jack is stuck in is applied On object, twisting by then pulling spanner is applied object.

The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model System.All employing equivalents or equivalence replacement and the technical scheme that formed, all fall within this utility model rights protection scope it It is interior.
