(57) Abstract Topic Ascent and descent angle appropriateness adjustment the manipulation handle which is made unrestrictedAt the same time with resolution or the assembly of the computer, quite efficient, quickly columnu. Solutions In the farming machine, the angle which is provided in the farming machine itselfMaking extend on left and right side of the degree adjustment base, B the tubed axial bar which it adheresIn 18, ascent and descent angle in multiple phases the adjustment manipulation han which is made possibleHandle Tip 8b of dollar A and 8b axial support pin component 10Through, the axis stick. As for aforementioned manipulation handle A two these haMake ndoru frame 8,8. The said handle frame 8,8Tip approaching support possible support sudden piece 19,19 aforementioned angular pitchSudden facilities do on left and right both sides of the integral base B. At the same time aforementioned handAbbreviation just above of aforementioned axial arrival place of ru frame 8,8, resolution or assemblyThe time, in the aforementioned tubed axial bar 18 edge as needed person in charge the person in charge stopping concave surface which it can make stopForming 8b2, it becomes.
