The working process of the portable electric drill winch embodiment is shown in fig. 5, and the winch main body, the electric hand drill (4) and the rope (6) are combined during working.

The winch is characterized in that a rope (6) is installed firstly, the rope (6) is guided by a guide wheel (21) and enters a groove of a single grooved wheel (1), then the rope is wound for less than one circle around the groove of the single grooved wheel (1), under the action of axial round holes (11) or radial convex ribs (12) on arms at two sides of the V-shaped of the single grooved wheel (1), the single grooved wheel (1) generates certain friction force on the rope (6), and the rope (6) extends out of a winch main body after passing through a pressing wheel (22). The load is connected with the bracket (5) through a load hook (7).

The rope (6) has a turning direction when passing through the guide wheel (21), the tension is generated at the traction load (7) of the rope (6) when being stressed, the tension is transmitted to the pinch roller (22) through the first connecting rod (23) and the second connecting rod (24), the pinch roller (22) generates a rotating moment through a hinge shaft (25), the moment presses the rope (6) in the groove of the single sheave (1) in a rolling way, so that the friction force of the rope (6) is multiplied, the magnitude of the rolling pressure is positively correlated with the tension of the rope (6) acting on the guide wheel (22), and the tension of the rope (6) is positively correlated with the traction of the load (7), so that the rolling pressure of the pinch roller (22) on the rope (6) can dynamically track the traction change of the load (7), the rolling pressure is increased during heavy load to prevent the rope (6) from slipping, and the rolling pressure is reduced during light load to be beneficial to reducing the abrasion of the rope (6).

Then an electric hand drill (4) is installed, and a quick chuck of the electric hand drill (4) is movably connected with an outer shaft (35) of the speed reducer.
