Abstract
The invention provides a wrench conveniently used in narrow space. An integrated handle is arranged at the tail end of a wrench bar which is formed by combining two blocks; a plurality of transmission gears meshed with each other through teeth are arranged in the wrench bar; a rotating handle into which a box spanner can be sleeved is arranged on a shaft rod above a driving gear at the rear end of the arrayed transmission gears; a replaceable hexagonal spanner is arranged on the shaft rod under a driven gear at the front end; the wrench bar which is formed by combining two blocks is integrally connected through a plurality of fastening bolts on the two sides. In use, the end of the driven gear is inserted into the narrow space and the bolt is inserted through the hexagon spanner, and then the rotating handle at the rear end is rotated through the box spanner, so that the bolt is fastened without moving the handle.
Description
Technical field
The present invention relates to the spanner of a kind of fastening bolt, specifically a kind of spanner facilitating narrow space to use.
Background technology
Traditional spanner all by handler and allow spanner fasten or demounting bolt, this traditional spanner can arbitrarily rotate use in unlimited space, but if when the bolt fastening in more narrow locus, but cannot launch handle to carry out rotating use, this brings inconvenience to a lot of operations being badly in need of installation or removal bolts.
Content of the invention
The common wrench that it is an object of the invention to solve above-mentioned existence cannot provide a kind of spanner facilitating narrow space to use in the problem of narrow space normal operating, can be very easily at the fastening of narrow space position or demounting bolt.
The present invention includes handle, the technical scheme being used is: is closed up the wrenching bar tail end combining by two pieces and is provided with the handle being integrated, wrenching bar is built with several travelling gears being engaged by teeth, axostylus axostyle above the driving gear of the travelling gear rear end being arranged is equipped with the swing handle that can be inserted in double offset ring spanner, and the axostylus axostyle below the driven gear of front end is equipped with removable six side's spanners.
Technique scheme includes: described two pieces are closed up the wrenching bar combining and connected as one by several trip bolts of both sides.
It is arranged over a cover plate at two pieces of wrenching bars closing up composition.
The present invention has following good effect: by above-mentioned such whole installation, the spanner being constituted structurally unusual science, when using in narrow narrow space, and can be by below the driven gear of front end
Six side's spanners insert in the groove of bolt, double offset ring spanner can be inserted on the swing handle of rear end to rotate, due to by the engagement arrangement of several travelling gears, when rotating the driving gear of rear end, drive several travelling gear to rotate immediately simultaneously, finally drive driven gear swivel bolt, thus i.e. reach fastening or demounting bolt in the case of motionless handle, the present invention solve present conventional spanner must with hand handler and overall could use and cannot fasten in narrow narrow space or the difficult problem of demounting bolt, scientific and reasonable in design, use extremely convenient.
Brief description
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
