Description

Ring-type combined spanner

The utility model relate to other classes in the hand tools not to be covered be used for fastening, connect, the instrument of dismounting, be a kind of spanner or box spanner, a kind of combination or multipurpose hand tool in other words conj.or perhaps.

At present the complete set of wrench that uses all is one group of discrete single-piece instrument usually, and these complete sets of wrench not only use inconvenient, and makes troubles to taking care of, carry etc.U.S. Pat 4606247 discloses a kind of chain complete set of wrench, and it is to be flexibly connected mutually by contiguous block by several spanner cell blocks that become even number to form, and it has made things convenient for carries and use, but not attractive in appearance in the moulding, uses also not ideal enough.

The purpose of this utility model provides a kind of annular combination wrench of handsome in appearance, more convenient use.

Technical solution of the present utility model is: a kind of annular combination wrench, spanner cell block with even number, flexibly connect by contiguous block between each spanner cell block, the spanner cell block comprises substrate and driving end, the difference of itself and prior art is: driving end is fixed on the front portion on the outer side plane of substrate, and the postmedian on the outer side plane of substrate is the room that holds a back spanner cell block; Driving end comprises fixed body and working end, and a neck that summary is thin is arranged between fixed body and working end; Working end and neck are positioned at outside the residing base plan of fixed body.

Working end in the utility model all is a kind of in stiff portion at hand, adjustable wrench head, box spanner head, the Allen wrench head or is the combination of above-mentioned two or more Wrench head.Certainly, also can adopt other suitable spanner or other hand tools heads as the working end.

The installation axis of the fork spanner head in the utility model, the opening direction of adjustable wrench head and neck, fixed body has an angle.This angle can be 15 ° or other proper angle.Certainly, opening direction also can adopt the form that overlaps with installing between axis.

Angle of the relative substrate updip of box spanner head in the utility model.Certainly, also updip not perhaps adopts neck is bent into stair-stepping form.

The utility model can be made the supporting mass of bearing sleeve Wrench head on substrate when employing has the box spanner head of updip angle or adopt form with the neck bending behind the box spanner head.The form that this supporting mass can adopt the fixed body with driving end to be connected as a single entity, certainly, also other suitable forms.

Each driving end working end is the smooth burnishing surface through polishing in the utility model, and neck is the matsurface without polishing.Certainly also can be all through polishing or through other suitable treatments.

The side camber face or the inclined-plane of the fixed body in the utility model.Certainly, also can not make arcwall face and inclined-plane, or make other suitable shapes.

Spanner cell block in the utility model is good with 4,6,8.Certainly, also can adopt the cell block combination of other suitable number.

The utility model has the advantages that: simple in structure, volume is little, in light weight, material is economized, easy to manufacture, cost is low, price is only for the part of the same specification complete set of wrench, compare with former United States Patent (USP), practicality is better, easy to use, gripping is comfortable.The working end of driving end and neck are positioned at outside the residing base plan of fixed body, and more convenient in the operation, applicability is better.Neck is thinner, and is both more attractive in appearance, the tool set that more is near the mark again, thereby preferably being widely used.The installation axis of wrench opening direction and neck, fixed body has an angle, and is also not only more attractive in appearance, and is more convenient for using.Fixed body side camber face or inclined-plane etc., more comfortable when making gripping, also more convenient use.Adopt the combination of multiple driving end, make that function is many, purposes is wide, more convenient.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 6 is the structural representation of adoptable the third spanner cell block of the utility model.

Fig. 7 is the right view of Fig. 6.

Fig. 1, Fig. 2, Fig. 3 have described an embodiment of the present utility model.It is to be constituted by 6 fork spanner cell blocks.Each cell block has substrate 1 respectively, 5,9,13,17,21, be fixed with fixed body 2 on outer side plane one end, 6,10,14,18,22, fixed body is anterior by

neck

3,7,11,15,19,23 are connected with working

end

4,8,12,16,20,24, each working end is the fork spanner head, the opening of each Wrench head adopts different sizes (certainly, also can there be the part identical), to constitute a suitable spanner series group, as adopting 6 respectively, 7,8,9,10,11, or adopt 11,12,13,14,15,16, certainly, also can adopt other suitable combinations.The direction of each opening all tilts 15 ° with neck, the fixed body installation axis on substrate, certainly also 12 ° or 16 ° etc.Each neck is slightly more tiny than working end and fixed body, and adopts not machined surface, becomes the shape of approximate ellipsoidal as adopting the cross section.And each working end, or add each fixed body outer surface and all can adopt the form flat or that polish or polish again of milling.Each substrate two ends all has breach, has pin-and-hole on the substrate of breach both sides, and the pin axle 25 of can packing in the pin-and-hole relies on the pin axle to be equipped with between two adjacent substrate and flexibly connects piece 26, with this each substrate is linked to be a ring-type integral body.One is all made in substrate in each spanner cell block, fixed body, neck, working end, makes through fine finishining as adopting integral body to cast out again.

Fig. 4, Fig. 5 have described the adoptable another kind of spanner cell block of the utility model, also form by substrate 27, fixed block 28, neck 29, working end 30, the box spanner head has been adopted in its working end, angle of updip is omited than substrate 27, fixed body 28, neck 29 in working end 30, also can adopt the form of bending neck certainly.Have at substrate 27 two ends on the substrate of breach 32, breach 32 both sides and have for the pin hole 31 that penetrates the pin axle.The above-mentioned spanner cell block of 6 or 8 different sizes is linked to be an annular by contiguous block and pin just can constitutes another embodiment of the present utility model.When actual fabrication, also can on fixed block 28 or substrate 27, make for putting the supporting structure of putting the working end 30 of inclining.As make inclined-plane etc. so that more stable and more smoothly when in use gripping.

Fig. 6, Fig. 7 have described adoptable the third spanner cell block of the utility model.Each cell block among this cell block and Fig. 1 is basic identical, and substrate 35, fixed block 36, neck 37, working end 38, breach 40, pin hole 39 are also arranged, but different be above the fixed block and the side in the arc-shaped so that more comfortable when gripping.4,6 or 8 these cell blocks also can be formed a ring spanner combination by contiguous block, pin, constitute another embodiment.

The utility model also can have some other embodiment, as with 4-8(or other suitable number) heads such as the box spanner of appropriate size, inner hexagon spanner, adjustable wrench bring in ring spanner or other set of tools that constitutes a combining form as work.
