Description

A kind of adjustable wrench

Technical field

The utility model belongs to hardware & tools technical field, relates to a kind of spanner, is specifically related to a kind of adjustable wrench.

Background technology

Be applicable to the spanner tightening six square head bolts and six square nuts, having can the adjustable wrench of adjustment width, and GB GB/T 4440 is described later in detail its size and technical requirement; Also the fork spanner of unadjustable width is had, GB GB/T 4393 is described later in detail its size and technical requirement, define multiple specification determined, specification refer to be applicable to use six sides opposite side distance from, such as 8 millimeters, 10 millimeters, 12 millimeters, 14 millimeters, 17 millimeters, 19 millimeters etc.Not only there is a metric system, metric system, such as specification 6.35 millimeters (1/4 inch), 12.7 millimeters (1/2 inches) etc. can also have been bought from the market; The limit deviation of GB GB/T 4390 pairs of wrench opening sizes has detailed regulation.

Adjustable wrench can adjustment width, and regulate more convenient, but its adjustment worm screw does not have fixture, in use its A/F often changes, and width becomes large or diminished, and can not correctly be engaged six sides, need constantly to adjust, and uses and inconvenient.If width exceedes the limit deviation required by GB GB/T 4390, be less than again the distance of six sides to angular vertex, tighten although six sides also can be engaged, be easy to skid, be also easy to six sides to destroy.In order to prevent destruction six side, some machining producer forbids that workman uses adjustable wrench, but is equipped with multiple fork spanner to workman, spends more fund, takies more place and deposits.Carrying multiple fork spanner when keeping in repair also not too convenient, spending higher.

In view of this, adjustable wrench and fork spanner respectively have pluses and minuses, if both advantages together, just can design the more perfect spanner of one.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, provides a kind of stationarity relative to adjustable wrench good, can adjust again the adjustable wrench combining both advantages of width relative to fork spanner.

The utility model is achieved through the following technical solutions:

A kind of adjustable wrench, comprises fixed part, movable part and attachment pegs;

Fixed part comprises shank, connection part and fixing jaw, and connection part, with chute, traverses chute and is provided with several fixing holes; Fixing jaw is provided with fixed clamp face;

Movable part comprises and connects tenon and movable jaw, traverses connection tenon and is provided with several movable spans; Movable jaw is provided with movable clamping face;

Coordinate with slide by connecting tenon, movable part and fixed part form moving sets, fixed clamp face is parallel and relative with movable clamping face, distance between them is A/F, when movable part is along moving sets translation, A/F is along with change, and operationally, this pair of planar coordinates with two opposite planar of six sides respectively;

Attachment pegs comprises connecting section and positioning head, when connection tenon moves to specific position along chute, movable span aligns with the axial line of fixing hole, and connecting section inserts fixing hole and movable span simultaneously, then the relative position of movable part and fixed part is fixed, and the size of A/F is fixed.At this moment hand-held shank, makes fixed clamp face be engaged six sides with movable clamping face, just can twist bolt or nut.Such as, connect tenon to move along chute, when A/F is 6.35 millimeters, fixed part there is a hole just in time align with the hole axial line of on movable part, connecting section inserts fixing hole and movable span simultaneously, then the relative position of movable part and fixed part is fixed, and it is bolt or the nut of 6.35 millimeters that the utility model can be used for stubborn across flats.A/F be 8 millimeters, 10 millimeters or other size time, corresponding fixing hole also can be set and align with movable span axial line, and insert attachment pegs.

The beneficial effects of the utility model: relative to fork spanner, a utility model can comprise the function of more than one piece fork spanner, need not carry multiple fork spanner again during maintenance, carry a utility model just passable, weight saving, take up room minimizing, easy to carry, spend less.Relative to monkey wrench, A/F is fixing, can not change, and can correctly be engaged six sides, not need adjustment width, easy to use, is not easy six sides destroying screw bolt and nut, is not easy to skid, safer.

Detailed description of the invention

Below in conjunction with drawings and Examples, the present invention is further described:

Embodiment: see Fig. 1 to Fig. 7.

A kind of adjustable wrench, comprises fixed part A, movable part B and attachment pegs C;

Fixed part A comprises shank A01, connection part A02 and fixing jaw A03, connection part A02 with chute A04, traverses chute A04 and is provided with several fixing holes, as illustrated A6.35, A8, A10, A12, A12.7 etc.; Fixing jaw A03 is provided with fixed clamp face A05;

Movable part B comprises and connects tenon B02 and movable jaw B03, traverses connection tenon B02 and is provided with several movable spans, as illustrated B6.35, B8, B10, B12, B12.7 etc.; Movable jaw B03 is provided with movable clamping face B05;

Be slidably matched by connecting tenon B02 and chute A04, movable part B and fixed part A forms moving sets, fixed clamp face A05 is parallel with movable clamping face B05 and to right, distance between them is A/F D, when movable part B is along moving sets translation, A/F D is along with change, and operationally, this pair of planar coordinates with two opposite planar of six sides respectively;

Attachment pegs C comprises connecting section C01 and positioning head C02, when connection tenon B02 moves to specific position along chute A04, movable span and fixing hole correspondingly axial line align, connecting section C01 inserts fixing hole and movable span simultaneously, then the relative position of movable part B and fixed part A is fixed, and the size of A/F D is fixed.At this moment hand-held shank A01, makes fixed clamp face A05 be engaged six sides with movable clamping face B05, just can twist bolt or nut.Such as, connect tenon B02 to move along chute A04, when A/F D is 6.35 millimeters, hole A6.35 and hole B6.35 just in time axial line align, connecting section C01 inserts fixing hole and movable span simultaneously, then the relative position of movable part B and fixed part A is fixed, the present embodiment can be used for stubborn across flats be 6.35 bolt or nut.Other hole, A8 and B8 is corresponding, and corresponding A/F D is 8 millimeters, and A10 and B10 is corresponding, and corresponding A/F D is 10 millimeters, will not enumerate.

Be not limited to the A/F D arranged cited by the present embodiment, also other size can be set.

The beneficial effect of the present embodiment: relative to fork spanner, a present embodiment can comprise the function of more than one piece fork spanner, need not carry multiple fork spanner again during maintenance, carry a present embodiment just passable, weight saving, take up room minimizing, easy to carry, spend lower.Relative to monkey wrench, A/F is fixing, can not change, and can correctly be engaged six sides, not need adjustment width continually, easy to use, is not easy six sides destroying screw bolt and nut, is not easy to skid, safer.
