Abstract
The utility model belongs to hardware tools, and relates to a crank block adjustment type multipurpose outer hexagon wrench, in particular to an adjustable type multipurpose outer hexagon wrench which can be used on bolts or nuts in a range of sizes. The crank block adjustment type multipurpose outer hexagon wrench comprises a hand shank, wherein the end of the hand shank is connected with two or three disks through pin shafts, outer edges of the disks are hinged with six two-bar linkage mechanisms, a V-shaped clamp plate of 120 degrees is fixed on each outer linkage rod, the end portions of the outer linkage rods are installed in a sliding chute of a position limiting module, the position limiting module is fixed on a sleeve housing, and the sleeve housing is connected with the pin shafts on the hand shank in clearance fit mode. The crank block adjustment type multipurpose outer hexagon wrench is simple in structure, convenient to operate, and suitable for various specifications of the bolts or the nuts, and can prevent the bolts or the nuts from being damaged.
Description
Technical field
The utility model belongs to hardware & tools, is specifically related to a kind ofly can be used in the bolt of certain limit size or the multiplex outer hexagonal spanner of the adjustable of nut.
Background technology
At present, although people use monkey wrench can adapt to bolt or the nut of plurality of specifications, but owing to regulating trouble, and holding area is only two faces of bolt or nut, be easy to damage bolt or nut, cause dismounting very difficult, therefore often need the connector station of dismounting generally not adopt monkey wrench to operate at some.The contact area of telescopic spanner and bolt or nut is large, can avoid damaging bolt or nut, but only can be suitable for a kind of bolt or nut of size, in when work, because the difference of bolt or nut specification need to be equipped with multiple spanners, and the process of choosing, change, adjusting can be brought great inconvenience to operating personnel.
Summary of the invention
For improving the deficiency of above-mentioned spanner, the purpose of this utility model be to provide a kind of simple in structure, easy to operate, applicable to the multiplex external hexagonal socket wrench of crank block adjustment type of plurality of specifications bolt or nut.
The corresponding scheme that the above-mentioned technical problem of solution the utility model adopts is: handle end connects 2～3 disks by bearing pin, hinged six cover two linkages of outer rim of disk, on the connecting rod of each outside, fix the V-arrangement clamp of 120 °, the end of outside connecting rod packs in the chute of spacing module, spacing module is fixed on sleeve shell, and sleeve shell and handle pin shaft clearance are connected.
The quantity of described disk is 3, together overlapped, two linkage positioned opposite on every disk, and the angle that whole two connecting rod machines are arranged on circumference is divided equally.
6 spacing module deciles are fixed on the inwall of sleeve shell, and V-arrangement clamp is vertically fixed on the connecting rod of outside.
The beneficial effects of the utility model are: the connecting rod of this box spanner and spacing module composition the slider-crank mechanism of simple in structure, reliable operation, can adjust easily the switching degree of V-arrangement clamp, thereby can be applicable to plurality of specifications bolt or nut, with same outer-hexagonal bolt or nut of spanner just being twisted to plurality of specifications.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model V-arrangement clamp closes up view.
Fig. 3 is the full open mode schematic diagram of the utility model V-arrangement clamp.
In figure: spacing module 1, V-arrangement clamp 2, inner side connecting rod 3, bearing pin 4, disk 5, handle 6, outside connecting rod 7, sleeve shell 8.
Detailed description of the invention
With reference to Fig. 1～3, by bearing pin 4, the disk 5 together with overlapped connects with three in the end of the handle 6 of this outer hexagonal spanner, the outer rim of each disk 5 is by articulated two linkages of hinge, six cover two linkages are distributed in whole circumference with average angle altogether, and two linkages on every disk 5 are positioned opposite.Two linkages are to be formed by stud connection by inner side connecting rod 3 and outside connecting rod 7, on the connecting rod 7 of each outside, be fixed wtih the V-arrangement clamp 2 that is bent into 120 °, the end of outside connecting rod 7 packs in the chute of spacing module 1, and spacing module 1 is fixed on the inwall of sleeve shell 8.Sleeve shell 8 is cylindric, is connected with 4 one-tenth matched in clearance of bearing pin of handle 6.When inner side connecting rod 3 and outside connecting rod 7 are during in same straight line, each V-arrangement clamp 2 apart from the center of circle of bearing pin 4 farthest, the hexagonal outline size maximum that each V-arrangement clamp 2 forms, suitable to large-sized hex bolts or nut operation; When inner side connecting rod 3 and outside connecting rod 7 are during in angle state, disk 5 plays a part crank, make outside connecting rod 7 along the chute in spacing module 1 according to predetermined direction straight line slippage, V-arrangement clamp 2 forms minimum hexagon, can be to undersized hex bolts or nut operation.
