Description
Technical field
The utility model belongs to maintenance tool technical field, relates to a kind of Combined 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 usually shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut hold bolt or nut.During use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.
Because the size of bolt, screw and nut etc. is different, therefore in order to spanner can pull the bolt, screw and nut etc. of any size, spanner is all generally complete, but complete spanner quantity is more, carries trouble.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of Combined wrench easy to carry, applied widely.
The purpose of this utility model realizes by following technical proposal: a kind of Combined wrench, it is characterized in that, comprise body and several pulling heads, described pulling head comprises head and a pair backstay, the size of several heads is all not identical, all described backstays in the same size, one end of described body is provided with a pair locating hole along the length direction of body, the opening part of described locating hole is provided with arc butting section, storage part is provided with in the middle part of described body, described storage part protrudes from the both sides in the middle part of body, described storage part is symmetrically set with some groups of positioning jacks centered by body, often organize positioning jack and comprise a pair locating hole, the opening part of a pair locating hole is provided with arc butting section, the aperture of all locating holes is all consistent, and the external diameter of backstay is slightly less than the aperture of locating hole, described backstay is inserted in corresponding locating hole and pulling head is located mutually with body, described head is resisted against on arc butting section.
The quantity of pulling head is multiple, varying in size of each pulling head head, namely each head is all used for pulling nut, bolt and the screw etc. of specifying size, and this Combined wrench has multiple pulling head, namely the nut of different size, bolt and screw etc. can be pulled, applied widely; And each pulling head can insert in the locating hole navigating to correspondence by backstay, pulling head is located mutually with body, namely body and several pulling heads are linked to be an entirety, easy to carry, during use, the pulling head being arranged in storage part place is inserted into the locating hole of body end, easy to operate.
In above-mentioned a kind of Combined wrench, the quantity of described pulling head is six, and the group number of described positioning jack is six groups, and the group number of described positioning jack is not less than the quantity of pulling head.Quantity and the positioning jack group number of pulling head all set according to actual conditions, the group number of positioning jack is no less than the quantity of pulling head, ensures that each pulling head all can grafting be positioned in positioning jack, makes pulling head and body be linked to be an entirety, easy to carry, easy to use.
In above-mentioned a kind of Combined wrench, the degree of depth of described locating hole is consistent with the length of backstay.Locating hole plays the effect of location to backstay, namely locating hole plays the effect of location to pulling head, when pulling head embedding is positioned at the end of body, pulling head is now used for pulling nut, screw or bolt, backstay now and the clamping of body phase, make pulling head improve enough power, make pulling head can pull nut, screw or bolt.
Compared with prior art, the Combined wrench that the utility model provides comprises multiple pulling head, and the size of each pulling head head is all not identical, makes this combination wrench can pull the multiple bolt, the screw and nut that vary in size; And this combination wrench is provided with the positioning jack that quantity is greater than pulling head quantity, makes all pulling heads all can be connected and is positioned on body, pulling head and body is made to form integral structure, easy to carry, applied widely.
