How to unfold the automatic umbrella?

Question 1: Why can't the automatic umbrella be put away automatically? Because it was invented only for automatic opening, but it was not designed with automatic retraction function. But that doesn't mean you can't do automatic recycling, just to reduce costs and make it more popular.

Question 2: How to collect the automatic umbrella? Either the button or the hand.

Question 3: My automatic umbrella can be opened and closed, but it can't stand up, and there is a white line. How to fix it? As long as there is a place to repair shoes near the vegetable market where you live, you will repair umbrellas. In your case, 5 yuan has the most money.

Question 4: What about the automatic umbrella? Can it be repaired? I can't open the umbrella. When I took it back, I put the umbrella head against the floor in the right way for 40 minutes. I grabbed the umbrella handle with both hands and pressed it hard, and I went in. I'm in the same situation.

Question 5: I can't get my automatic umbrella back, and there are white lines on it. What should I do? Actually, this umbrella is not broken. There's just a temporary situation. All you have to do is take back the umbrella head and handle, that is, close it like a small umbrella before opening it.

Question 6: How to open the automatic umbrella again? Must it be taken back completely? Press the button of the card slot.

Question 7: The principle and structure of automatic umbrella. The development of umbrella style needs a complicated process. First of all, you need to go to the umbrella stand factory to know whether the skeleton structure is feasible and the production process. After all, thinking and doing are two different things. After making sure that it can be made, you can apply for a patent according to the process. After applying for a patent, you can add the patent number to the conspicuous position of the umbrella stand, so that other manufacturers will not dare to copy it. Then you need to arrange the quantity of products according to your own needs, communicate with the manufacturers, and designate the manufacturers to do it according to the quantity after reaching an agreement, no more or less. The designated finished products must all be yours, which is basically no problem. But the problem of development is mainly the problem of capital, which is large in quantity, low in price, small in quantity and expensive. You know why. You can keep asking questions.

Question 8: Fully automatic umbrella is closed and automatically opened, and the button below has slipped. You should see its structure. It is made of iron and plastic.

Question 9: What should I do if I press the automatic umbrella button and still can't close it? I don't know if it has been repaired. As you said, it is most likely that the rope is stuck. You can't solve it yourself. Don't dismantle it, laymen are easily injured by the main spring inside.

Question 10: What should I do if the automatic umbrella cannot be collected? Ordinary automatic umbrellas are designed to open automatically, so there is no automatic retraction function.

The working principle of an automatic umbrella depends on a spring with tension. When the user presses the button, the umbrella will open automatically due to the release of spring pressure.

If an automatic umbrella retracting device is designed, opposing forces will be used on the same axis, which will inevitably form opposing forces. In mechanics, the resultant force of two opposite and equal forces is zero, that is, the umbrella can neither be opened nor retracted.

If we add a device to open and close the umbrella automatically, it will greatly increase the cost of the umbrella and make it big and bulky. No manufacturer wants to do it, and no one will buy it.
