Description

Adjustable wrench with ratchet spanner function

Technical field

The utility model relates to a kind of monkey wrench, particularly relates to a kind of adjustable wrench that gets final product continuous elasticity bolt, nut that once inserts.

Background technology

At present, fastening or demolition nut or bolt, fork spanner commonly used, monkey wrench or ratchet spanner carry out, and it is fixing that fork spanner is pulled mouth, will select one by one according to the size of bolt or nut during use, very inconvenient; Though adjustable wrench can be in the certain size scope bolt and nut of degree of tightness different size, the same with fork spanner when fastening or dismounting nut or bolt, need repeatedly pincers to go into, rotate, withdraw from, pincers are gone into again, so circulation can fulfil assignment, its efficient is too low; In addition, when we needed at some position of narrow and small position of activity space such as automobile degree of tightness nut, when repeating to a last orientation by an azimuth transfer, the angle of its handle swing needed 60 degree, can make the insertion of jaw seem difficult like this; Though ratchet spanner can be worked continuously, high efficiency need be selected the annular cover according to the nut size when using equally one by one, then, is enclosed within on the nut and could works, and uses also very inconvenient.

Summary of the invention

The purpose of this utility model is to provide that a kind of usefulness is same can carry out spanner that disposable pincers are gone into, the adjustable wrench with ratchet spanner function of degree of tightness continuously to the bolt and nut in the certain size scope.

The purpose of this utility model can realize by following technical measures: a kind of adjustable wrench with ratchet spanner function, comprise head and shank, head is provided with jaw, fixedly pulling of jaw back the screw rod that control Flexible spanner body moves up and down is housed in the body window, this screw rod kink is on the axis of guide, its key is: be hinged with lever near on the fixed handle of head through pivot pin, this lever covers on the fixed handle, and is provided with locking mechanism; End in contact under the front end of described lever and the screw rod is set with spring on the axis of guide of screw rod top; On window limit the hypertonic card is installed near jaw.

Describedly be provided with teeth by fixedly pulling the jaw that body and Flexible spanner body constitute.Respectively be provided with the teeth that are complementary of row fixedly pulling body and Flexible spanner body joint portion.Be provided with the scale that helps the operator to adjust jaw size rapidly on the body fixedly pulling.

Described locking mechanism is made up of reed, shank of the key and dead bolt, wherein dead bolt is " 7 " font, the lower end is fixed on the fixed handle, reed is a strip, be installed in the lever inwall, the shank of the key kink is on reed, and stretch out outside the lever its upper end, cavity is arranged at the shank of the key bottom, and this cavity openend is over against the upper end of dead bolt.

According to the above-mentioned adjustable wrench that assembles with ratchet spanner function, because the jaw opening and closing are freely, can carry out disposable insertion, continuous degree of tightness to the bolt and nut in the certain size scope, greatly improved operating efficiency; Because jaw is provided with teeth, even block the bolt diagonal angle, but also wrenching bolt like this, in the narrow and small occasion in those spaces, also can be operated freely.Overcome in the prior art one and can only pull the bolt of a certain size to fork spanner or ratchet spanner, narrow and fork spanner of the scope of application and monkey wrench need insert repeatedly, pull, withdraw from, insert ..., ineffective deficiency.

Description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is locking mechanism 9 structural representations among Fig. 1.

The specific embodiment

Hereinafter with reference to accompanying drawing concrete structure of the present utility model is further described:

Referring to Fig. 1, adjustable wrench with ratchet spanner function described in the utility model, comprise head and shank, head is provided with jaw, fixedly pulling of jaw back the screw rod 6 that control Flexible spanner body 13 moves up and down is housed in the body window, these screw rod 6 kinks is characterized in that on the axis of guide 4: be hinged with lever 8 near on the fixed handle 11 of head through pivot pin 7, this lever 8 covers on the fixed handle 11, and is provided with locking mechanism 9; 6 times end in contact of the front end of described lever 8 and screw rod are set with spring 5 on the axis of guide 4 of screw rod 6 tops; When lever 8 during, order about screw rod 6 and drive Flexible spanner bodies 13 and move up and down, thereby jaw is dwindled or amplify around the rotation of pivot pin 7.Near the window limit of jaw hypertonic card 3 is being installed, this hypertonic card 3 can make teeth 12 clutches of fixedly pulling body and Flexible spanner body according to Flexible spanner body 13 is whether stressed.Be provided with teeth 1 by fixedly pulling the jaw that body and Flexible spanner body constitute, this mainly is when work, can be multi-faceted vise nut, to accelerate overwork and to prevent to skid; Fixedly pull body and Flexible spanner body joint portion and respectively be provided with the teeth 12 that a row is complementary, during work, utilize these teeth, the pressure that is born by the Flexible spanner body is originally conducted to fixedly pull body, make lever not have pressure, and operation freely.In addition, the fulcrum appropriateness that makes the traditional activity spanner like this, helps alleviating the operating physical force of lever 8, handled easily forward; Be provided with the scale 2 that helps the operator to predict to adjust jaw size on the body fixedly pulling, this scale 2 directly is engraved in fixedly to be pulled on the body, has avoided conventional spanner need vise the drawback that nut is adjusted jaw usually; The locking mechanism 9 that is provided with on lever 8 is made up of reed 14, shank of the key 15 and dead bolt 16, wherein dead bolt 16 is " 7 " font, the lower end is rotated with on fixed handle 11, reed 14 is a strip, be installed in lever 8 inwalls, shank of the key 15 kinks are on reed 14, and stretch out outside the lever 8 its upper end, cavity is arranged at shank of the key 15 bottoms, and this cavity openend is over against the upper end of dead bolt 16.When shank of the key 15 retreats, dead bolt 16 inserts in shank of the keys 15 cavitys, lever 8 and fixedly pull the body shank and be close to and link to each other, and jaw just can vise nut and arbitrarily rotate, and shank of the key 15 moves forward, then two handles separation.In addition, the afterbody at handle is provided with anti-slop serrations 10.
