Abstract
The utility model relates to a hand tool, in particular to a combined double offset ring spanner, which comprises a handle. Both ends of the handle are respectively fixed with a wrench; the wrenches are quadrilateral; the surfaces of the bottom ends of the wrenches are connected with the handle, and the four side walls thereof are respectively provided with a quincuncial gear ring, wherein a centre hole is arranged in the handle; an force application rod is arranged in the centre hole; the force application rod glides along the hole wall of the centre hole of the handle; the centre of the top end of the handle is provided with a hole; and the hole is communicated with the centre hole of the handle. The spanner can effectively shorten the length of the double offset ring spanner, and thereby, a worker can conveniently use, the working efficiency is improved and the use cost is reduced.
Description
Technical field
The utility model relates to a kind of hand-operated tools, especially a kind of combination double offset ring spanner.
Background technology
At present, every end of existing double offset ring spanner has only a plum blossom hole or plum blossom gear ring, and nut or bolt that each plum blossom hole or plum blossom gear ring can only corresponding same sizes use, therefore nut or the bolt that existing double offset ring spanner can only two kinds of different sizes of dismounting.But in real work, nut or bolt have multiple shape and specification, when the nut of dismounting different size or bolt, need to prepare manyly could work double offset ring spanner.So not only brought the inconvenience of carrying, also improved the expense of the instrument of purchasing simultaneously, increased use cost to the staff.
In addition, one is regular length for existing double offset ring spanner, when working in less space; occur because the long cisco unity malfunction that causes of double offset ring spanner through regular meeting; must select the short double offset ring spanner of length this moment for use, cause needing in the work often to change instrument, reduce operating efficiency.
The utility model content
The purpose of this utility model is to overcome poor, the ineffective defective of existing double offset ring spanner versatility, has proposed a kind of combination double offset ring spanner that has boosting-rod.
The utility model is to adopt following technical scheme to realize: a kind of combination double offset ring spanner, comprise handle, the two ends of handle are fixed with spanner respectively, described spanner is quadrangle, the bottom end surface of spanner is connected with handle, be equipped with the plum blossom gear ring on its four sidewalls, wherein, be provided with centre bore in the described handle, be provided with boosting-rod in the centre bore, boosting-rod slides along the hole wall in handle center hole, and the center, spanner top of at least one side is provided with the hole, this hole is connected with the handle center hole, and spanner top central hole is provided with stopping means.
In the utility model, described spanner and handle can be integral structure, also can wait other modes fixedly connected by welding.
The beneficial effects of the utility model are: by in the handle of combination double offset ring spanner boosting-rod being set, can shorten the length of double offset ring spanner effectively, and can set the extension elongation of boosting-rod according to the real work space, can reach by boosting-rod simultaneously and apply the purpose that less power can be finished the work, be convenient to workman's work, improve operating efficiency, and reduced use cost.

The specific embodiment
As shown in the figure, this combined type double offset ring spanner comprises handle 1 and spanner 2, and the two ends of handle 1 are fixed with spanner 2 respectively, and handle 1 and spanner 2 are integral structure.Spanner 2 is quadrangle, wherein, the lower surface of spanner 2 is connected with handle 1, be equipped with plum blossom gear ring 4 on four sides of spanner 2, the shape and size specification of each plum blossom gear ring 4 is all different, therefore this spanner goes for eight kinds of specifications of nuts or bolt, has good versatility, and is easy to use.Be provided with centre bore in the handle 1, boosting-rod 3 is arranged in this centre bore, and boosting-rod 3 is along the hole wall slip in handle center hole.The center, top of both sides spanner 2 is equipped with the hole, and this hole is connected with the centre bore of handle 1, and spanner top central hole is provided with stopping means simultaneously, prevents that boosting-rod 3 from skidding off in the centre bore of handle 1.By the regular length that boosting-rod 3 can shorten double offset ring spanner on the one hand is set, it still can be used in the less working environment in space, use boosting-rod 3 to reach when working on the other hand and use less power can finish screwing or unscrewing of nut or bolt.When being in not duty, boosting-rod 3 is placed in the central bore of handle 1.
When using this double offset ring spanner, shape and specification according to nuts and bolt, select to use plum blossom gear ring corresponding on the spanner, after choosing the plum blossom gear ring is enclosed within on nut or the bolt, when working space is enough big, boosting-rod can be extracted out from handle 1, and be stretched out the spanner outside, finish screwing or unscrewing of nut or bolt by the rotation boosting-rod.When working space hour, can finish screwing or unscrewing of nut or bolt by rotary handle.
In the utility model, also can only at the center, top of a side spanner hole be set, this hole is corresponding with the centre bore in the handle, and this place, hole is provided with stopping means.
Claims (2)
1. combination double offset ring spanner, comprise handle, the two ends of handle are fixed with spanner respectively, and described spanner is quadrangle, the bottom of spanner is connected with handle, be equipped with the plum blossom gear ring on its four sidewalls, it is characterized in that: be provided with centre bore in the described handle, be provided with boosting-rod in the centre bore, boosting-rod slides along the hole wall in handle center hole, the center, spanner top of at least one side is provided with the hole, and this hole is connected with the handle center hole, and spanner top central hole is provided with stopping means.
