The present invention relates to an angle-adjustable joining unit for a farming tool and a manual tool which enables a user to attach and detach a work unit to and from a shaft of the farming tool and the manual tool in an easy manner, to adjust an angle at various degrees, and to replace and use various kinds of farming tools. According to the present invention, the joining unit is formed on not only a front end portion of the farming tool or the manual tool but also a front end portion of the shaft so that work unit is joined to the shaft by the joining unit. The joining unit has a fixation hole formed in the center thereof. A plurality of angle adjustment holes are formed in circles having the same center on an outer side of the fixation hole. A fixation hole is formed in the center on an outer side of the joining unit. A fixation plate is arranged to have a fixation protrusion formed to be inserted into the angle adjustment hole. When a fixation screw is inserted and fixated to the fixation holes of the fixation plate and the joining unit, the protrusion of the fixation plate is inserted and fixated to the angle adjustment hole. The work unit is fixated to the shaft at a desired angle by twisting the joining unit after loosening the fixation screw. |
