Angle adjustable connecting part for farm equipment and hand tools

An angle adjustable connecting part for farm tools and hand tools, comprising:

• a first connecting part fixed to a side of a working part into which a handle is fitted, the first connecting part having a fixing hole formed at a center thereof and a plurality of first angle adjustment holes arranged in a circle centered on the fixing hole;
• a second connecting part fixedly fitted onto a side of the handle into which the working part is fitted, the second connecting part having a fixing hole formed at a center thereof and a plurality of second angle adjustment holes arranged in a circle centered on the fixing hole;
• a fixing plate having a fixing hole formed at a center thereof and a fixing projection formed at an outer side thereof to be fitted into the first and second angle adjustment holes of the first and second connecting parts;
• and
• a fixing screw fitted into and fixed to the fixing holes when the fixing projection of the fixing plate is fitted into the first and second angle adjustment holes of the first and second connecting parts with the first connecting part of the working part, the second connecting part of the handle and the fixing plate overlapping one another,
• wherein an angle formed between the first angle adjustment holes of the first connecting part fixed to the working part is different from an angle formed between the second angle adjustment holes of the second connecting part fixed to the handle and the first angle adjustment holes of the first connecting part are arranged in an asymmetrical manner with respect to the second angle adjustment holes of the second connecting part such that one of the first angle adjustment holes of the first connecting part and one of the second angle adjustment holes of the second connecting parts are coincident with each other and other holes of the first angle adjustment holes and other holes of the second angle adjustment holes are not coincident with each other when the first connecting part and the second connecting part are arranged overlapping each other and the fixing projection of the fixing plate is fitted into the one of the first angle adjustment holes of the first connecting part and the one of the second angle adjustment holes of the second connecting part,
• wherein the first connecting part fixed to the working part and the second connecting part fixed to the handle are arranged overlapping each other, and the fixing plate is arranged on a side surface of the first and second connecting parts in an overlapping manner.
