Description

There is the monkey wrench of asymmetric pair of V-arrangement jaw and ratcher function

Technical field

The utility model belongs to hardware & tools technical field, relates to a kind of monkey wrench with asymmetric pair of V-arrangement jaw and ratcher function.

Background technology

Manual normal activity spanner is that people are used for dismantling the common tool of nut or bolt at ordinary times, the jaw of normal activity spanner is rectilinear, during with normal activity spanner dismounting nut or bolt, nut or bolt are that two contact surfaces are stressed, beat, skidding is easily caused when exerting oneself large, make the corner of nut or bolt yielding, to more firmly nut or Bolt dismantling difficulty or efficiency low.During dismounting air-conditioning duct, easy beat, the more bad dismounting of unsettled pipeline, the monkey wrench of symmetrical two V-arrangement jaws, its two V-arrangement monkey wrenches are when dismantling nut or bolt, it is stressed that nut or bolt become four contact surfaces, stressed evenly, the monkey wrench of symmetric double V-arrangement jaw becomes Chinese chess double off-set spanners and equally uses, can not skid to when more firmly nut or Bolt dismantling, not beat, quick detachable, unsettled pipeline might as well be dismantled, but symmetric double V-arrangement jaw dismounting nut, always opening nut will be frequently regulated in a lot of situation when bolt or unsettled pipeline, also make its efficiency low.Also there is complex structure in the adjustable ratchet wrench of other type, cost is high, not easily popularizes, or the position of card nut or bolt is away from the school, front end of jaw, or bayonet socket attachment design is limited, a lot of nut or Bolt dismantling not, make adjustable ratchet wrench range of application restricted.

Utility model content

In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of monkey wrench with asymmetric pair of V-arrangement jaw and ratcher function, there is the simple feature of structure, can by nut or bolt card in the front end of jaw, there are two kinds of occupation modes, first, there is asymmetric pair of V-arrangement monkey wrench when dismantling nut or bolt, it is stressed that nut or bolt become three contact surfaces, the adjustable ratchet wrench of asymmetric pair of V-arrangement jaw can not skid when nut or Bolt dismantling, quick detachable, there is the function of ratchet, certain dismounting nut, bolt efficiency improves, three contact surfaces are stressed and to have ratcher function two features are maximum differences with symmetric double V-arrangement jaw monkey wrench, second, or adopt two stress surface designs of normal activity jaw of spanner, its jaw is zigzag, object is the reduction of spanner, and it realizes ratcher function and to fall back distance, simpler, user will have certain skill.

The utility model solves the technical scheme that its technical problem adopts: a kind of monkey wrench with asymmetric pair of V-arrangement jaw and ratcher function, comprise wrench body, the top of wrench body is provided with jaw, jaw is surrounded by two, left and right jaw, the inner side that two jaws are relative is provided with asymmetric groove, described jaw comprises movable jaw and fixing jaw, wherein the inboard groove of movable jaw is in the shape of the letter V, the groove of another fixing jaw is then made up of V-shaped ratchet surface and has two adjacent contact surfaces that can contact with bolt or nut, one can be formed near jaw front end with nut between two jaws, the parallel gap of bolt makes to be disassembled bolt or nut with wherein two contact surfaces of side and a contact surface of opposite side contact, stressed object is stablized when realizing dismounting, and be than blocking nut or the large space of bolt diagonal diameter near jaw rear portion, nut or bolt can be relatively rotated with spanner, realize ratcher function, it is realize monkey wrench dismounting nut that jaw surrounds semicircular space, parallel rear end, front end, the key of bolt and ratcher function.

Described movable jaw can also be designed to indentation, thus bolt or nut are fixed by two stress surfaces.

The v-depression of described movable jaw is less than the v-depression on fixing jaw.

Described movable jaw at transverse shifting, thus can change jaw size, and another fixing jaw utilizes ratchet principle, nut can be made, bolt moves in oblique direction, thus realize the drawback movement of monkey wrench, realize ratcher function, described wrench body is integrated with jaw to be connected.

The beneficial effects of the utility model are: rectilinear for normal activity spanner jaw is processed into asymmetric pair of V-arrangement jaw, make nut or bolt stressed by two contact surfaces, become three contact surfaces stressed, dismounting nut or bolt time uniform force, can not skid, quick detachable firmly nut or bolt, ratchet spanner can be worked as again use when dismantling nut or bolt, increasing work efficiency; The design of jaw working end is in jaw front end, and range of application increases; The structure of the monkey wrench of the utility model asymmetric pair of V-arrangement jaw and material and production technology and traditional rectilinear normal activity spanner similar, large-scale production cost can not increase.

The utility model is also provided with the advantage of double off-set spanners simultaneously, and make the nut of dismounting or bolt not yielding, three contact surfaces are stressed, not beat, not slippage, quick detachable firmly nut or bolt; There is ratchet spanner function, increase work efficiency; The design of jaw working end is in jaw front end, and range of application increases; People reduce the preparation quantity, particularly work high above the ground of instrument or the ideal tools of air-conditioning suspended piping dismounting when dismantling nut or bolt, according to its above-mentioned ratchet principle, also can design jaw is zigzag monkey wrench, two stress surfaces.Indentation decreases spanner, and it realizes ratcher function and to fall back distance, and save production cost, also can design bayonet socket is fixing ratchet spanner, makes the stiff hand of ratchet that its cost is cheaper, but does not regulate bayonet socket function.
