Abstract
The present invention relates to a quick multi-purpose ratchet wrench which is used for quickly screwing or unscrewing various screw nuts (bolts), water pipes and twisting special workpieces. The wrench is composed of a handle, a hook-shaped wrench opening and a spring fixing structure. The head part of the wrench presents a semicircle shape, a strip-shaped notch is arranged below the head part and is used for containing the rear part of the hook-shaped wrench opening inserted in the notch, and the rear part of the hook-shaped wrench opening is fixed in the strip-shaped notch by pins; the spring fixing structure is mainly composed of a spring and a spring fixing pin, the spring fixing pin crosses through the strip-shaped notch and forms a fixed fulcrum which is wound by one end of the spring, the other end leg of the spring penetrates through an inserting strip hole part of the hook-shaped wrench opening to form the other fulcrum, and non-skid teeth are arranged at the middle part and the back part of a wrench opening head, and a semicircle head of a wrench body. The wrench opening can rotate for 90 DEG or more than 90 DEG. The present invention has wide application and quick and convenient use.
Description
Affiliated technical field:
The present invention relates to a kind of multi-purpose fast ratchet wrench that is used for tightening fast or unclamping the special-shaped workpiece of various nuts, bolt, water pipe and twisting.
Background technology:
The hand tools that generally is used to tighten or unclamps the special-shaped workpiece of various nuts, bolt, water pipe and twisting is polytype spanner, plumbing combination pliers etc.Though Chinese patent 93218174.0 has possessed above-mentioned all kinds of function, and pull when under the effect of spring, circling round and mouthful can automatically reset, constitute a multi-purpose fast ratchet wrench, but in concrete real the work, the phenomenon that fulcrum of spring comes off from the strip notched wall often takes place because the spring structure of this spanner is unreasonable, this spanner can't be used, influenced operating efficiency.Thereby there is certain defective in Chinese patent 93218174.0.
Summary of the invention:
The objective of the invention is to provide a kind of improved multi-purpose fast ratchet wrench, the defective that it can overcome above-mentioned existence effectively improves its operating efficiency.
The object of the present invention is achieved like this:
Spanner is made up of handle handlebody, handle body head construction.Handle body head construction comprises that colluding shape pulls mouth, spring-fixed structure and strip notch.Its head with collude shape and pull a mouthful corresponding side and be semicircle shape, the semicircle lower head has a strip notch to connect whole handle body head, collude shape and pull the metastomium attenuation,, and by pin this is colluded shape and pull metastomium attenuation partial fixing in the strip notch so that insert in this strip notch; Spring-fixed structure is mainly by spring, spring steady pin, strip notch with collude shape and pull the metastomium attenuation and partly constitute: the spring steady pin crosses bottom, strip notch two side, become spring one end foot and twine fixed pivot on it, spring other end foot penetrates and colludes shape and pull the insertion cylindrical void attenuation of metastomium and partly form another fulcrum; Pull oral veutro and the back Lower Half all has anti-slop serrations; Pull mouth and can do 90 or rotate greater than the openings of 90 degree.
Description of drawings:
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a plane structure chart of the present invention.
Among the figure 1, the handle body, 2, collude shape and pull mouth, 3, spring-fixed structure, 4, handle body head, 5, anti-slop serrations, 6, strip-shaped grooves, 7, pull metastomium, 8, pin, 9, spring, 10, spring steady pin, 12, spring terminal foot fixed pivot, 13, another fulcrum of spring terminal foot, 14, opening, 15, pull mouthful back and head veutro anti-slop serrations.
The specific embodiment:
Among Fig. 1, pull mouthfuls 2 under the effect of spring 9 tension force, will pull mouthfuls 2 and upwards withstand, make and pull mouthful 2 head veutros and semicircle shape handle body head 4 outsides form an opening 14, handle body semicircle head 4 has anti-slop serrations 5 and pulls mouthful 2 head veutros and has anti-slop serrations 15, to prevent round piece slippage from opening 14.Pull mouthfuls 2 and can do 90 or rotate greater than the openings of 90 degree.When pulling mouthful 2 back anti-slop serrations 15 and being used for shut-down operation, thumb is pulled mouthfuls 2 and is discharged workpiece; Spring-fixed structure 3 is by spring 9, spring steady pin 10, strip-shaped grooves 6 and pull metastomium 7 and form.Spring steady pin 10 crosses strip-shaped grooves 6, becomes the sufficient fixed pivot 12 that twines on it of spring 9 one ends, and spring 9 other ends foot penetrates the insertion bar bore portion of pulling metastomium 7 and forms another fulcrum 13.
Claims (2)
