Abstract

The utility model provides an adjustable spanner, belonging to a hardware tool. The utility model which is used for screwing a screw bolt and a screw nut is composed of a spanner handle 6, a fixed spanner opening 1, an adjustable wheel 4, an adjustable wheel shaft 3, and a movable spanner opening 2, wherein, the fixed spanner opening 1 and the spanner handle 6 are connected as a whole, and the adjustable wheel 4 is arranged in a square hole 7 on the spanner handle 6; the adjustable wheel shaft 3 and the spanner handle 6 are in screw connection, and the movable spanner opening 2 is matched with the adjustable wheel 4. The utility model is characterized in that an included angle between a spanner edge 8 on the fixed spanner opening 1 and a spanner edge 9 on the fixed spanner opening 1 is 120 DEG; an included angle between a spanner edge 10 on the movable spanner opening 2 and a spanner edge 11 on the movable spanner opening 2 is 120 DEG; an included angle between the axial lead of the adjustable wheel 4 and the spanner edge 10 is 120 DEG; the spanner edge 9 is parallel to the spanner edge 11, and the spanner edge 8 is parallel to the spanner edge 10.

Description

Adjustable spanner

The utility model relates to a kind of hardware ﹠ tools, especially a kind of four limit monkey wrenches.Be mainly used in turn-knob bolt, nut etc.

Present widely used monkey wrench all is to drive the Flexible spanner mouth by the regulating wheel on the handle to move, and Flexible spanner mouth and the spacing of fixedly pulling mouth are changed, thus two corresponding limits of fishbolt or nut.Because bolt or nut mostly are hexagon or four limits, use existing monkey wrench, can only make stressed the rotating of two opposite side wherein, so often because of folder does not tightly cause coming off, skidding, dangerous accident takes place very easily during work, influences operating efficiency and job morale.Also having a kind of widely used double offset ring spanner at present, though it can make the hexagon of hexagonal (hexagon)nut simultaneously stressed, stiff, uses cumbersomely, must be the spanner of outfit and nut specification equal number.

It is simultaneously stressed that the purpose of this utility model provides a kind of nut four limits that make, and comes off when preventing the turn-knob nut, four limit monkey wrenches of skidding.

Technical solution of the present utility model is: a kind of four limit monkey wrenches, by handle 6, fixedly pull mouthful 1, place regulating wheel 4 in the square hole 7 on the handle 6, form with the adjusting wheel shaft 3 of handle 6 thread connection, the Flexible spanner mouth 2 that matches with regulating wheel 4 with handle 6 combines as a whole, it is characterized in that: fixedly pulling pulling limit 8 and pulling limit 9 angles on the mouth 1 is 120 °, pulling limit 10 and pulling limit 11 angles on the Flexible spanner mouth 2 is 120 °, the axial line of regulating wheel 4 is 120 ° with pulling limit 10 angles, pull limit 9 and to pull limit 11 parallel, pull limit 8 and to pull limit 10 parallel.

The utility model compared with prior art because the Flexible spanner mouth; Fixedly pull the limit that contacts mouthful with nut and be respectively the flanging that is mutually hexagonal angle, and opposite side is parallel, the regulating wheel axial line is mutually hexagonal angle with the limit of pulling of close regulating wheel, make four to pull the corresponding limit of two couples that the limit is close to nut simultaneously, and make four limits stressed with advancing, unlikelyly during rotary nut come off, skid, reduce unsafe factor, increase work efficiency.

Fig. 1 is the structural representation of the utility model embodiment.

Below in conjunction with drawings and Examples the utility model is described further:

As shown in Figure 1: fixedly pull mouth 1 and be structure as a whole with handle 6, the front portion of handle 6 is provided with square hole 7, and regulating wheel 4 places in the square hole 7, regulating wheel shaft 3 one ends inserts in handle 6 bodies, the other end is axle cap 5 and handle 6 thread connection, regulating wheel 4 is supported in the square hole 7, and rotatable.The regulating wheel appearance is provided with spiral grooves, matches with Flexible spanner mouth 2, rotates regulating wheel 4 and can make Flexible spanner mouth 2 parallel moving.The limit of pulling of pulling on the mouth is four, pulls limit 8 and 9, pulls limit 10 and 11 and be mutually hexagonal angle respectively, pull limit 10 and become hexagonal angle with the axial line of regulating wheel 4, and the two relative limits 8 and 10,9 and 11 parallel respectively of pulling.Pull limit two groups of corresponding surfaces of binding nut simultaneously for four during use, make four faces simultaneously stressed.Prevent to come off, skid.
