The tent pole is blown and bent, what's the way to straighten it?

Answer: Block one end of the bent rod, then pour fine yarn into it from the other end, fill it tightly, and then block the mouth. Gently tap the bend (V or U) with a wooden hammer (stick), and continuously pour sand into the pipe. Repeat the above steps until it is straight, with light force. The wind resistance strength of the rod after being knocked straight has decreased, and a slightly thicker pipe can be placed here to increase its strength. If the rubber band is difficult to connect during operation, it can be removed before proceeding with the above operation.
Normally, aluminum or iron pipes should be inserted at the most stressed part of the tent pole to increase strength.
If it's fiberglass, use a hot hair dryer to blow it straight or go to the study outdoor club to exchange it for 5 yuan.
