Abstract
The utility model discloses a combined wrench with a wide application range. The combined wrench comprises a wrench sleeve and more than two wrench units, wherein a nut sleeve hole is formed in the middle of each wrench unit; pins are arranged at the lower ends of the wrench units; guide grooves are respectively formed on the left and the right sides of the wrench units; insertion holes matched with the pins are formed between the guide grooves and the nut sleeve holes; an open slotted hole for exposing the nut sleeve holes is formed on the front panel of the wrench sleeve; slide blocks matched with guide grooves are arranged on the left and the right sides of the wrench sleeve; the pins of one wrench unit is movably connected with the insertion holes of the next wrench unit; and the wrench units are inserted into the wrench sleeve through the guide grooves on the wrench units after being connected. The utility model can provide nut sleeve holes in which nuts are completely sleeved, thereby avoiding the phenomena of disengaging, damaging the plane surfaces of the nut and the like caused in the process of screwing the nut; the utility model can also provide nut sleeve holes of various specifications, thereby achieving a wide applicable range; and the combined wrench has the advantages of compact structure, convenience in use and portability.
Description
Technical field
The utility model relates to a kind of spanner, particularly a kind of combination wrench.
Background technology
Modal spanner is double offset ring spanner and fork spanner in the daily life.
Double offset ring spanner is provided with spanner at the two ends of trigger piece, and spanner is provided with plum-blossom sleeve.Generally, the plum-blossom sleeve internal diameter at trigger piece two ends varies in size, and is generally the specification of adjacent two models.There is certain shortcoming in double offset ring spanner: plum-blossom sleeve is multiple tooth structure, is not easy fastening for the nut of irregularity, and threads off easily in the rotation process; Each spanner can only be used for a kind of nut of specification, and whole double offset ring spanner only is applicable to the nut of two kinds of specifications and models.
Fork spanner is provided with open-end wrench at the trigger piece two ends, and opening can block four planes of target nut, and also surplus have two planes not to be stuck, and easily the nut plane destroyed in the rotating nut process like this.Fork spanner generally is provided with two spanners that specifications and models are different at the trigger piece two ends, a spanner can only be used for the nut of two kinds of specifications.
The utility model content
Technical problem to be solved in the utility model provides a kind of nut of plurality of specifications model and combination wrench that can be convenient for carrying of being applicable to.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of combination wrench comprises that spanner cover and two are with the upper ejector lever unit; Middle part in described spanner unit is provided with the nut trepanning, is provided with pin in the lower end of described spanner unit, and the and arranged on left and right sides in described spanner unit is respectively equipped with gathering sill, is provided with the jack suitable with pin between described gathering sill and nut trepanning; Be provided with the opening slotted eye that exposes the nut trepanning on the front panel of described spanner cover, the and arranged on left and right sides of overlapping at described spanner is provided with the slide block suitable with gathering sill; Adjacent two spanner unit flexibly connect by pin and jack, and the spanner unit after the connection inserts in the spanner cover by the gathering sill on it.
The inscribed circle diameter of the nut trepanning on each spanner unit is different.
Lower end at described spanner cover is provided with the handle that has the hole, and described handle and spanner cover flexibly connect.
The technology beneficial effect that adopts technique scheme to obtain is: the utility model can provide the nut trepanning that nut can be entangled fully, has avoided threading off, destroying in the rotating nut process phenomenon on nut plane; The nut trepanning of plurality of specifications model also can be provided, and the scope of application is extensive; The utility model compact conformation, easy to use, easy to carry.

The specific embodiment
By Fig. 1 to embodiment shown in Figure 5 as can be known: combination wrench comprises that 5 and two in spanner cover is with upper ejector lever unit 1; Middle part in described spanner unit 1 is provided with nut trepanning 6, lower end in described spanner unit 1 is provided with pin 2, and arranged on left and right sides in described spanner unit 1 is respectively equipped with gathering sill 3, is provided with the jack 4 suitable with pin 2 between described gathering sill 3 and nut trepanning 6; On the front panel of described spanner cover 5, be provided with the opening slotted eye that exposes nut trepanning 6, be provided with the slide block suitable with gathering sill 3 in the and arranged on left and right sides of described spanner cover 5; Adjacent two spanner unit 1 flexibly connect by pin 2 and jack 4, and the spanner unit 1 after the connection inserts in the spanner cover 5 by the gathering sill on it 3; The inscribed circle diameter of the nut trepanning 6 on each spanner unit 1 is different, arranges from big to small successively according to the specifications and models of nut commonly used; Lower end at described spanner cover 5 is provided with the handle 7 that has the hole, and described handle 7 is clamping or grafting with the connected mode of spanner cover 5.
In use, according to the selected required spanner unit 1 of the specifications and models of target nut, required spanner unit 1 pushed to the upper end of spanner cover 5 and with 6 complete exposing of whole nut trepanning, handle 7 is taken off from spanner cover 5, other spanner unit 1 that do not meet target nut specification are pushed away the bottom that is put into spanner cover 5 by gathering sill 3, adjacent two spanner unit 1 are connected with jack 4 by pin 2, handle 7 are installed to the lower end of spanner cover 5 again.So just can use the 1 pair of target nut in target spanner unit to operate.Handle 7 can prevent to be positioned in the use spanner unit 1 generation landing phenomenon that spanner overlaps 5 bottoms, the convenient use.
The utility model is combined the spanner unit 1 of all size model, and is applied widely; Whole combination wrench is formed one by pegging graft, and spanner unit 1 can also make full use of the space as trigger piece, has improved utilization rate; Spanner cover 5 is provided with anti-skidding line, is convenient to firmly; Handle 7 is provided with the hole, is easy to carry.
