For example, you can place your thumb on the finger rest and press down on the grip with your other fingers. The reason is that it is configured so that it can be done. The position where the finger rest is fixed to the hollow operating rod is the grip. It can be placed above or in the middle of the grip. Fix the finger rest to the middle part of the grip In this case, provide a long hole in the middle of the grip for the finger rest to pass through.

[0006]

[Effect]

Place your thumb on the finger rest provided on the hollow operating rod of the blind and grip the grip with your other fingers. , and then use your thumb to push up the finger rest and push down on the other grips in a relative motion. , the grip is lowered and the lifting cord is unlocked. At this time, the hollow operating rod The upward force from the thumb and the downward force from the other fingers act in opposite directions. Because they are balanced, no force acts directly on the hollow gear and hollow operating rod. the result, Even if the grip is lowered repeatedly, the connecting part between the hollow operating rod and the intermediate gear will be subject to repeated stress. There is no risk of damage. When you place your thumb on the finger rest, feel how much pressure is being applied. Since the grip can be lowered while moving, the grip can be lowered slowly or quickly. Wear.
