Claim 6:
7. The winch according to claim 1, wherein a clutch shifter (2.5) is provided between the n-stage planetary carrier (2.2 b) and the drum (3), and the outer diameter of the clutch shifter execution unit tubular member (2.5 b) is provided with an outer spline (2.5 b6) combined with a bearing, which is combined with an inner spline of an inner ring of a right end cap bearing (7) of the winch and is axially slidable, or a sliding bearing (7b) is arranged between the outer diameter of the clutch shifter execution unit tubular member (2.5 b) and the bearing of the right end cover of the transmission, so that the clutch shifter execution unit tubular member (2.5 b) can axially slide, and a tooth form or tooth cog III (2.711) is arranged on the left side of a central tubular member (2.71) of the half coupling and is dynamically combined with a tooth form or tooth cog I (2.3 a1) of the power output gear of the driving shaft, the left side of the outer spline (2.712) of the central tubular member is meshed with the right side spline (2.5 b4) of the clutch shifter execution unit tubular member and can axially slide, the right side is meshed with the inner spline of the half coupling driving member (2.72), and the bearing (7) with two inner ring inner splines arranged on the inner diameter is combined with the driving shaft (2.3), a pressing plate (2.74) is arranged on the left side of the driven member (2.73) to limit the axial movement of the driving member (2.72), and a gap between the half coupling driving member (2.72) and the driven member (2.73) is increased to enable the clutch shifter execution unit tubular member (2.5 b) to freely rotate by an angle alpha, wherein the angle alpha is multiplied by an n-stage planetary gear transmission ratio i which is equal to or larger than an angle of one tooth pitch p of the left clutch II (2.5 b1), a follower is bolted to the center of the right end cap of the drum 3.
