Description
Technical field
The invention belongs to installation and removal technical field of tools, be specifically related to a kind of multifunctional wrench.
Background technology
Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is shaped with opening or the trepanning of grip bolt or nut usually in the one or both ends of shank, during use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.
Existing spanner is divided into two kinds substantially, fork spanner and adjustable wrench.Fork spanner, also known as open-end wrench (or claiming solid wrench), is mainly divided into double ended spanner and single head fork spanner.Its effect is extensive, mainly acts on the categories such as machinery overhaul, apparatus, family expenses finishing, motor vehicle repair.The many complete production of fork spanner, manufacturing cost is higher; And the screw that can only to turn on spanner at most two models, when screw is dismantled to screw model unfamiliar personnel, need repeatedly to try out, use inconvenience.
Existing adjustable wrench, its A/F can regulate within the specific limits, is used to a kind of instrument that the is fastening and nuts and bolt of a loose different size.Existing monkey wrench when using needs opening repeatedly to load and unload on nut, so aperture efficiency nut opposite side must be allowed larger, otherwise nut clamping is just difficult to handling.
Summary of the invention
The object of the invention is to solve the deficiencies in the prior art, a kind of multifunctional wrench simultaneously with fork spanner and the advantage with adjustable wrench is provided.The present invention is achieved by the following technical solution:
A kind of multifunctional wrench, become with stiff end head group by handle, movable end, runner, described handle (7) is provided with groove 1 (11) and groove 2 (10), described fixing termination (3) is arranged in groove 2 by the first pin (4) is rotating, is provided with draw-in groove (6) in fixing termination; Described runner (5) is arranged in groove 1 by the second pin (13) is rotating, and runner outer surface is provided with helical tooth A (14), is provided with the second spring (12) between runner (5) and handle (7); Described movable end (2) one end is sleeved in draw-in groove, and one end is provided with the first spring (8) in addition, and movable end lower surface is provided with the movable end tooth B (9) be engaged with helical tooth A phase; Described the first spring (8) one end is arranged on movable end, and one end is arranged on fixing termination backboard (1) in addition.
The angle of the angle between described fixing termination lower surface and handle upper surface is more than or equal to 5 degree and is less than or equal to 30 degree.
Described runner is round table-like.
The cross section of described helical tooth A and movable end tooth B is trapezoidal.
Described movable end surface is provided with anti-skidding striped.
Compared with prior art, the present invention has following beneficial effect:
The advantage contrasted with monkey wrench: 1) nutting speed is fast, 2) engaging is tighter.Because traditional activity spanner needs opening repeatedly to load and unload on nut, so aperture efficiency nut opposite side must be allowed larger, otherwise nut clamping is just difficult to handling, the present invention can by regulating runner, make it not exclusively corresponding with the draw-in groove of movable end, thus allowing the trapezoidal inclined plane of trapezoidal inclined plane Compressive activities termination of runner, two ends just can extrude nut, is tightly connected with nut.
The advantage contrasted with box socket set: the nut that 1) box socket set often tightens a kind of model needs the sleeve being equipped with separately a kind of model, and the present invention's spanner can adapt to multiple bolt, so more save material, more economical, carries more convenient.2) use owing to needing spanner to add sleeve combination when box socket set operates, and the present invention only needs an independent spanner, so operation is upper more convenient.3) when turning round nut, if nut enters stud certain depth, box socket set just cannot operate, because skirt depth is limited, and the present invention does not exist this problem.4) when nut or nut are in edge, because box socket set is pulled a lot thick because sidewall ratio is stayed, and need installing sleeve, may space constraint be subject to, cannot use.
The advantage contrasted with sharp-end ratchet wrench: 1) because a kind of sharp-end ratchet wrench of model can only be used for a kind of nut of model, and a kind of model of the present invention is applicable to the nut of a variety of model, so the present invention is more economical, carries more convenient.2) because sharp-end ratchet wrench sidewall is thicker, cannot make to stay and pull thin like that, so some narrow location cannot use, and the present invention is owing to being opening, there is not this problem.3) there is attachment at stud two ends in some cases, and nut is in centre, and this situation is unavailable sharp-end ratchet wrench just, and the present invention just can adapt to this situation.
