Description

Standby solid wrench

Technical field the utility model relates to a kind of standby spanner, belongs to hardware & tools a kind of and that monkey wrench is connected.

Background technology is in work and life, monkey wrench is as a kind of instrument of tightening with loose unloading bolt nut, in operating process, often there is the drawback that bolt nut is worked day and night, need to look for two spanners relatively to rotate application of force ability complete operation, preparation and the preservation of the instrument of giving are made troubles, and affect the efficiency of work.

Summary of the invention the purpose of this utility model be to provide a kind of both can with the monkey wrench use that is connected as a single entity, can easy and conveniently take again the standby solid wrench with the monkey wrench inverse pairs rotation application of force apart, compact conformation, is convenient to preserve, and increases work efficiency.

For above-mentioned purpose, the standby solid wrench that the utility model is designed, mainly comprises the parts such as wrench body, spring leaf, rivet, and spring leaf 2 is fastenedly connected by rivet 3 and wrench body 1.It is characterized in that wrench body is the steel plate material punching part with certain thickness and hardness, can meet intensity and the rigidity of daily solid wrench operation, the monkey wrench of its contour structure size and same specification matches.The afterbody of wrench body is stamped into the semicircle annular of drawing in to a side, encases monkey wrench afterbody circular arc.At wrench body middle front part, being close to palm has rectangular preiection also to homonymy, to strike out U-shaped on one side, embraces monkey wrench handle edge.In wrench body front portion, away from palm, have a rectangular aperture on one side, over against opening, with four rivets, one spring leaf is housed, spring leaf U-lag is walked around monkey wrench margo from bending in rectangular aperture and is held monkey wrench handle tightly.The polygonal hole as box spanner is processed in wrench body afterbody center of arc, aperture ratio monkey wrench afterbody circular hole is bigger, at wrench body Shang Yan handle center line correct position, output the hexagonal hole of a plurality of different specification sizes, when pitch of holes must guarantee to use each hexagonal hole operation, wrench body has the enough rigidity of resistance to deformation.At finger grips place, process two to four different size open slots, each open slot can be put into two or a finger wherein respectively.When the spacing of open slot must guarantee to use each open slot operation, wrench body has the enough rigidity of resistance to deformation.Its wrench body 1 afterbody is stamped into semicircle annular 6, and middle front part rectangular preiection 4 strikes out U-shaped, and spring leaf 2 curves U-lag 20, three places and jointly holds monkey wrench handle tightly in wrench body rectangular opening 10.On wrench body, be processed with polygonal hole 5,

open slot

7,8,9 and the

hexagonal hole

11,12,13,14,15 of different size, its size can contain the solid wrench size of the various standard bolt nuts of the maximum opereating specification of monkey wrench.

Owing to adopting said structure, the utility model and monkey wrench fit in one, both can wholely use, and also can easily separate dorsad and use.The standby solid wrench of different size, the maximum open scope of the monkey wrench of quantity, size and the same specification of its polygonal hole, hexagonal hole, open slot matches.(such as, monkey wrench maximum open is 40 millimeters, the maximum draw-in groove of standby solid wrench or the size of hole clipping are also 40 millimeters).The fluting of standby solid wrench or hole be of a size of contain within the scope of this solid wrench standard size of operable all bolt nuts.Because spring leaf and fixing rivet are in the middle concave surface of monkey wrench handle, and spring U-lag is curvedly from rectangular opening to go out, and has abdicated the margo of monkey wrench, so this place can obviously once not add additional thickness.While separately using, by standby solid wrench pull backward, spring leaf is held monkey wrench tightly and is skidded off backward; When whole use or preservation, the U-lag handle body rectangular preiection being curved and spring leaf U-lag block monkey wrench handle and push ahead, and when solid wrench afterbody semicircular ring encases the circular afterbody of monkey wrench, both combine securely.Simple and compact for structure, easy to operate.

The specific embodiment,

Below in conjunction with drawings and Examples, the utility model is further described.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the standby solid wrench of the utility model mainly comprises the parts such as wrench body 1, spring leaf 2, rivet 3.Wrench body 1, for having the steel plate material punching part of certain thickness and hardness, can meet the resistance deformation requirements of regular job.Before punching press, its afterbody is the eccentric circular ring 17 that multi-disc is separated by rim openings, curves the semicircle annular 6 of drawing in to a side after punching press, can embrace monkey wrench afterbody circular arc.The backward homonymy of rectangular preiection 4 punching press of middle front part strikes out U-lag, can block monkey wrench on one side.In wrench body front portion, there is below a rectangular opening 10, over against being drilled with four rivet holes 18 on it, surely firm with rivet hole 19 rivetings of spring leaf 2 by rivet 3, wrench body rivet hole 18 is identical with spring leaf rivet hole 19 apertures and spacing dimension, makes the rivet 2 can be smoothly that both rivetings are surely firm.Spring leaf 2 curves U-shaped to monkey wrench handle side rectangular opening 10 is interior, holds at any time another edge of monkey wrench tightly.Because spring leaf 2 and fixing rivet 3 are in the middle concave surface of monkey wrench handle, and spring leaf U-lag 20 is curvedly from rectangular opening 10 to go out, spring leaf 2 and rivet 3 got out of the way the margo of monkey wrench, so can't obviously once add additional thickness with wrench body 1 junction.Wrench body afterbody after punching press is processed with polygonal hole 5 over against semicircular ring center, more bigger than the monkey wrench afterbody circular hole of coupling.In the utility model embodiment, at wrench body, process below

open slot

7,8,9, the size of open slot 7 can be put the third finger and little finger of toe into, and

open slot

8 and 9 can be put middle finger and forefinger into respectively.When the spacing of open slot must guarantee to use each open slot operation, wrench body has the enough rigidity of resistance to deformation.Along on handle center's line 16 with

suitable interval

11,12,13,14, the 15 more or less hexagonal holes that distributing, when pitch of holes must guarantee to use each hexagonal hole operation, wrench body has the enough rigidity of resistance to deformation.The size of the polygonal hole 5 of these different sizes,

open slot

7,8,9,

hexagonal hole

11,12,13,14,15, can contain the solid wrench size of the various standard bolt nuts of the maximum opereating specification of monkey wrench.The size of wrench body open slot can be put one or two finger, the spanner of can easily holding with a firm grip into.
