　　Patent > Patent YOUNGPOWER New Type Solid Wrenches
Patent Number :　ZL89101752.6 　ZL00207251.3
Patent Right Holder:Chenwei(Senior Engineer)

1.when the new type double end wrench is operated on the nut,the force standing sides of the nut is different from the edges when the common double wrench is operated.The force standing situation is improved and the edges of nut is protected.So that the edges avoids being worn out.Paticularly available for rusty nuts,small fixed nuts,soft material nuts,precision equipment nut,etc.

2.Available for the blind area that the nuts are unseen.

3.Needless to leave the nut away when to continue operating on the nuts,particularly available for high frequency working angular change and speedy operation because of the wrench's two working surface.The new type double end wrenches holds the function of the ratchet wrenches.

4.The working space of the wrench head is narrower 30% or so than the common double end wrench's.(The Current Machinery Design Standard:Wrench Working Space Q12B148-73).Available for narrow working space while the common double end wrench can't be operated too.

5.New type combination wrench can be operated when the handle working space is below 30 degree.Available for car maintenance,narrow working space etc.

6.It's durable for its thickened force standing sides.Reported by WORLD INVENTION,CCTV,JAPAN NEWSLETTER ON INDUSTRIAL NEWS,U.S.POPULAR SCIENCE,FRANCE CANN TV STATION,etc.

Direction For Operation
1. The nut can be hold automatically from any direction while the new type double end wrench is operated on it.
　2. Loose the new type wrench and draw back when to change working surface.

　1.1　　　　　　　　　1.2　　　　　　　　　　1.3　　　　　　　　1.4　　　　　　　　1.5

3. When the working angular space is below 60 degree and unable to continue the next step,the same space can be hold by the back of the wrench and operated 30 degree,then turn the wrench back to continue the same operation when the working space is below 30 degree.

　　　　　　
4. The new type combination wrench(combined by the new type double open and box end wrench)can be operated according to diagram 4 to change 15 degree while the working space of wrench handle is below 30 degree and the nuts are unable to hold even though the wrench back is turned to operate.Repeat the same operation to meet the needs of the narrow working space.

5. New type double end wrench available for the narrow head working space while the common wrench is not operated(diagram 5).Also available for optimizing the machinery design
