Description
Technical field
The utility model relates to a kind of electric wrench and its magnetic sleeves.
Background technique
Electric wrench with sleeve is the tool being commonly used in people's daily work life, either in common machinery
Maintenance is still all essential in building construction installation process.But it is when in use, not necessarily rigid with nut due to sleeve
Good matching, before screwing on nut or after unscrewing nut, nut and nut shim are easy to fall off, this can in standard machinery maintenance
It to receive, but is unacceptable in the livewire work of power industry, especially complex circuit.
In livewire work or hot-line repair work, because of complex circuit and line security is apart from closer, it is desirable that work
Personnel will put on thick insulation tippet and wear three layers of gloves (gauze gloves, insulating glove, kid gloves).Using electricity
It before wrench nutting, needs first to be screwed on bolt nut shim and nut manually, but staff is wearing three layers of hand
It is inflexible to cover defensive position, easily falls it in operating nut and nut shim, so can not only there is electric power safety hidden danger,
It also needs to look for suitable nut and nut shim again, this is breakneck for livewire work, while can also aggravate work
The workload of personnel reduces working efficiency.
Utility model content
The purpose of this utility model is in view of the deficiencies of the prior art, to propose a kind of electric wrench and its magnetic sleeve, energy
It is enough to prevent nut and nut shim from falling off when fastening or removing the nut on bolt, it is easy to use, improve working efficiency.
The utility model is achieved through the following technical solutions:
A kind of magnetic sleeve of electric wrench, for preventing nut and spiral shell when fastening or removing the nut on bolt
Female gasket falls off, and including front opening and hollow sleeve body, horizontally moveable is arranged in sleeve body to block spiral shell
Female baffle and the spring being arranged between baffle and sleeve body rear end, sleeve body front end is provided with magnetic portion so that spiral shell is sucked
Female gasket offers relief hole on baffle, and spring has the cavity being connected to relief hole, and bolt may pass through relief hole and enter spring
Cavity.
Further, the sleeve body opening has magnetism by magnetization.
Further, the sleeve body is hollow cylinder.
Further, for the spring in the state of being not stretched or compressing, length is than the sleeve body length
Short 8-10mm.
Further, the baffle is arranged vertically in the sleeve body.
Further, the sleeve body rear end has necking.
The utility model is also achieved through the following technical solutions:
A kind of electric wrench, including wrench body and any magnetic sleeve as above, wrench body is arranged in magnetism
Sleeve rear end.
The utility model has the following beneficial effects:
1, in use, bolt passes through the cavity that relief hole enters spring, nut is blocked by baffle, and spring is in electric wrench
Effect is lower to be in compressive state, then spring applies a forward power to nut back end to withstand nut, and nut shim is by sleeve
The magnetic portion of ontology front end is sucked, and applies a power backward to push down nut, so as to make nut and nut pad to nut front end
Piece is not fallen, easy to use, improves working efficiency；On the other hand, since the thickness of the nut of different size is also not quite similar,
And under the action of the spring, no matter thin or thick nut can be completely into sleeve body, to make nut shim by magnetic
Property portion be sucked, so enhance the versatility of the use of the new type；The design of baffle relief hole, makes bolt may pass through baffle, from
And it avoids when in use due to spring-compressed tension caused by the collective effect of bolt and electric wrench, if spring-compressed mistake
Tightly, then it is easily excessive to the power of nut application, makes nut be easy to separate with electric wrench, leads to not continue to fasten or tear open
Except nut, and spring is also more easy to damage, therefore relief hole is arranged on baffle, can effectively buffer the pressure that bolt applies spring
Power, makes that the utility model using effect is more preferable, the service life is longer.
2, sleeve body opening has magnetism by magnetization, without in addition setting magnet, makes the utility model structure more
To be simple, it is also more convenient maintenance.
Detailed description of the invention
The utility model is described in further details with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1, sleeve body；11, magnetic portion；12, necking；2, baffle；21, relief hole；3, spring；4, bolt；5, spiral shell
It is female；6, nut shim.
Specific embodiment
Electric wrench includes wrench body and magnetic sleeve, and wrench body is arranged in magnetic sleeve rear end, as shown in Figure 1,
Magnetic sleeve is used to prevent nut 5 and nut shim 6 from falling off when fastening or removing the nut 5 on bolt 4.Magnetic sleeve
Including front opening and hollow sleeve body 1, horizontally moveable the baffle 2 that nut 5 is blocked in sleeve body 1 is set
And the spring 3 being arranged between 1 rear end of baffle 2 and sleeve body, 1 front end of sleeve body are provided with magnetic portion 11 so that nut is sucked
Gasket 6, baffle 2 are arranged vertically in sleeve body 1, offer relief hole 21 thereon, and spring 3 has to be connected to relief hole 21
Cavity, baffle can stretch with spring 3 or compress and move horizontally, and bolt 4 may pass through the cavity that relief hole 21 enters spring 3.
The opening diameter of 1 front end of sleeve body is slightly larger than 5 outer diameter of nut, and the bindiny mechanism of spring 3 and 1 rear end of sleeve body is existing skill
Art.
Sleeve body 1 is hollow cylinder, and magnetic portion 11 has magnetism by magnetization, and the magnetism is enough strong, can inhale
Firmly nut shim 6, moreover it is possible to nut shim 6 be made to block nut 5 so that it does not fall off.
For spring 3 in the state of being not stretched or compressing, length is 8-10mm shorter than 1 length of sleeve body, makes
The nut of different-thickness can be operated by obtaining electric wrench, versatile.
1 rear end of sleeve body has necking 12, and sleeve body 1 is arranged in wrench body by the necking 12, is specifically set
Setting mode is the prior art.
The above, the only preferred embodiment of the utility model, therefore the utility model implementation cannot be limited with this
Range should still belong to this that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description
In the range of utility model patent is covered.
