Description
Technical field
The present invention relates to machining tools art, particularly a kind of dismantling device used for narrow space.
Background technology
Spanner is a kind of conventional installation and removal instrument.It utilizes lever principle to twist bolt, screw, nut and other screw threads tightly to hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is shaped with clamp holder portion in the one or both ends of shank usually, and during use, threadingly direction of rotation applies external force and just can twist bolt or nut.In recent years, the box socket set original spanner technical foundation improved has been widely used the various aspects at processing manufacturing industry because of its quick-detachment function.
But, the ratchet spanner of current domestic use primarily of ratchet spanner main body and corresponding both sleeves superimposed and combinationally use, which adds the height of spanner, higher requirement be it is also proposed to corresponding usage space, therefore can not use in less space.
Summary of the invention
The object of the present invention is to provide a kind of dismantling device used for narrow space, it can tighten or dismantle nut or bolt fast in less space.Effectively reduce the height of spanner, thus extend the scope of application of spanner greatly, be specially adapted to little space inner nut or the use of bolt degree of tightness.
Technical solution of the present invention is such, a kind of dismantling device used for narrow space, comprise cover plate, outer sleeve, handle, spring, active body, inner sleeve, clip, it is characterized in that inner sleeve (6) is embedded into outer sleeve (2) inherent outer sleeve (2) and rotates, active body (5) is tubular structure, cylindrical is stepped, bottom is zigzag, middle and upper part is regular hexagon, inner sleeve (6) inside is regular hexagon, top is with active body (5) intermeshing zigzag, spring (4) top pressure active body (5) and inner sleeve (6) engage each other, inner sleeve (6) is placed in outer sleeve (2), blocked by the clip (7) of outer sleeve (2) bottom, cover plate (1) is welded on active body (5), inner sleeve (6) is inserted in nut or bolt, handle (3) clamping active body (5) middle and upper part, the sawtooth of inner sleeve (6) and the sawtooth phase single direction rotation of active body (5), its installation annexation is clip (7) top is inner sleeve (6), inner sleeve (6) top is active body (5), spring (4) is housed between active body (5) and outer sleeve (2), cover plate (1) is welded on above outer sleeve (2).
Inner sleeve (6) is embedded into outer sleeve (2) inherent outer sleeve (2) and rotates.
Active body (5) is provided with and inner sleeve (6) intermeshing sawtooth, and handle (3) has bayonet socket to be hexagon above.
Inner sleeve (6) has clip (7) below.
The bayonet socket of handle (3) is orthohexagonal bayonet socket, and bayonet socket snaps in the outside regular hexagon of active body (5).
Jigsaw fit between active body (5) and inner sleeve (6) is manufactured.
The sawtooth of active body (5), inner sleeve (6) is unidirectional tooth.
Advantage of the present invention is: the inner sleeve in nut or bolt engagement is embedded into outer sleeve inside, significantly reduces the height of spanner, thus extend the scope of application of spanner greatly, be specially adapted to the nut in little space or bolt.
