Claim 11:
12. The winch of claim 10, wherein a synchronizer I (11) is provided between the right plate of the n-stage planetary gear of the transmission (2) and the tubular member (2.5 b), and the clutch shifter execution unit tubular member (2.5 b) serves as a hollow power output shaft (2.2 b1) to directly output the rotation speed and torque of the left 1-n-stage planetary gear change;
an external spline I (2.5 b6) is arranged on the outer diameter of the right side of the clutch shifter execution unit tubular member (2.5 b) and is meshed with an internal spline of a center bearing (7) of a right end cover (2.1 c) of the transmission and can slide axially, and an optical axis is also arranged to be combined with a sliding bearing (7a) of the right end cover of the transmission and can slide axially; a connecting gear ring II (12.7) is arranged on the left side, a synchronizer II follower (12.8) with a conical surface II (12.6) is provided with a bearing (7c or 7b) with an inner ring and an inner spline, the bearing (7c or 7b) is combined with a driving shaft, wear-resistant material gaskets (8) are arranged on two sides, and an elastic retainer ring (9) is positioned on the driving shaft (2.3), the right spline (2.5 b4) of the clutch shifter execution unit tubular member is combined with the outer spline (12.81) of the follower of the synchronizer II and can slide axially; and an inner end cover (2.5 b7) is arranged on the right side of the tubular part and is positioned by an elastic retainer ring (9), and the optical axis part of the right end part of the driving shaft (2.3) without a spline is in contact with an oil seal of the inner end cover (2.5 b7); the gear clutch shifter drive unit II (2.5 a) drives the clutch shifter execution unit tubular member (2.5 b) to move the left synchronizer I (1) to the right side to separate, meanwhile, the joint sleeve II (12.1) of the right synchronizer II drives a positioning pin II (12.4), and a sliding block II (12.3) pushes the locking ring II (12.5) to be combined with the conical surface II (12.6), After the rotating speed of the driving shaft (2.3) and the rotating speed of the tubular member (2.5 b) are synchronized, the inner teeth (12.11) of the joint sleeve II are meshed with the joint gear ring II (12.7), the positioning pins (11.4 and 12.4) of the synchronizers I and II fall into the left slope feet (11.13 and 12.13) of the grooves I and II for locking, and the driving shaft (2.3) drives the tubular member (2.5 b) to directly output torque; a displacement sensor (6.2) and a rotating speed sensor (6.7) are arranged on a sensor support (6.1) on the left side of the gear clutch shifter drive unit II, and a rotating speed sensor (6.7) is arranged on a sensor support (6.1) on a transmission right end cover (2.2).
