Abstract
The invention relates to hardware spanner tools, and in particular relates to a telescopic sleeve double offset ring spanner. The telescopic sleeve double offset ring spanner comprises a sleeve ring, a pulling rod and a sleeve barrel, and is characterized in that the pulling rod internally passes through the sleeve barrel, wherein one end of the pulling rod is convexly arranged while the other end of the pulling rod is connected with the sleeve ring; and one side face of the sleeve barrel closed to the sleeve ring is inwards coiled. The telescopic sleeve double offset ring spanner is simple in structure, and suitable for being popularized.
Description
Technical field
This patent relates to the five metals Wrench, is specially a kind of telescopic sleeve double offset ring spanner.
Background technology
It is more when distribution network live line work generally touches charged for replacement insurance and disconnecting link; Because distribution all belongs to the city, bolt and gold utensil corrosion are comparatively serious, and pile crown all is in electriferous state on the bolt when insurance of workmen's charged for replacement and disconnecting link; The insulation blocking of must insulating; The operating personnel can't move back demolition with it and removes when removing up and down the pile crown bolt, when bolt corrosion is serious, uses bolt looseness agent and bolt grinder effect all not all right, and construction can't be carried out.Certainly can not employ burning torch, because spark can damage lead-in wire and insulated target.Generally can only its corrosion bolt be amputated in this case, but not only speed is very slow but also whole saw worker can be charged in saw for this working system, when phase spacing is nearer, can cause danger to the operating personnel, also can make the people tired out with the saw worker.It is tightly disconnected to adopt double offset ring spanner by force its bolt to be carried out when a kind of mode is arranged for operation, and this operation i.e. safety is quick again.Because the size of double offset ring spanner all has standard code, as the operating personnel can be very painstaking when tightly disconnected by force or can't tightly break when running into 12# or above bolt.Need improve existing double offset ring spanner.
Summary of the invention
This patent provides a kind of rational in infrastructure, construction labour-saving telescopic sleeve double offset ring spanner to above technical problem.
The telescopic sleeve double offset ring spanner is made up of lasso, tommy bar, ferrule sleeve, it is characterized in that: wear tommy bar in the ferrule sleeve, and a protrusion of tommy bar, lasso is connected the tommy bar other end, and ferrule sleeve leans on a side of lasso to curls inward.
In use, if do not need time too energetically, ferrule sleeve not to need to stretch, only the length with tommy bar promptly realizes changeing the effect of turning round.When needs reversed energetically, the expanding sleeve socket can double tommy bar length at most, realized that the long arm of force overcomes big resistance.
This patent is simple in structure, be suitable for promoting.

The specific embodiment
The telescopic sleeve double offset ring spanner is made up of lasso, tommy bar, ferrule sleeve, it is characterized in that: wear tommy bar in the ferrule sleeve, and a protrusion of tommy bar, lasso is connected the tommy bar other end, and ferrule sleeve leans on a side of lasso to curls inward.
In use, if do not need time too energetically, ferrule sleeve not to need to stretch, only the length with tommy bar promptly realizes changeing the effect of turning round.When needs reversed energetically, the expanding sleeve socket can double tommy bar length at most, realized that the long arm of force overcomes big resistance.
This patent is simple in structure, be suitable for promoting.
