For the manual hoist, whether it is an upward or downward operation, it is controlled by pressing the handle. So how are these two completely opposite operations formed?

Upon careful observation of the hand-operated hoist, you will notice that there is a mysterious component at the handle position that can be pulled, which controls the direction of the hoist's movement. Move the lever to the top, press the handle, and the weight will rise. Adjust the lever to the bottom, and press the handle to lower the weight. If the lever is adjusted to the middle, it will be in an unloaded state. At this time, you can freely pull the chain to adjust the distance between the upper and lower hooks.

Through the above introduction, do you understand the control button for lifting the hand hoist?
