The first method: When you can't bear to twist the flower, first apply some pressure to see if it rotates, or use a very small amount of force to twist. Sometimes it can also be effective, but if not, you have to consider other methods.
The second method: When you can't bear to twist it, you can choose to use a smaller model of flat screwdriver, gently punch a deep groove first, and then turn it out.
The third method: When you can't bear to twist it, use a small hacksaw to cut the screw into a straight line, and then you can use a straight line screw tool to unscrew it. Alternatively, you can use a small knife to repeatedly carve on the screw until the cross shaped screw is carved into a flat screw, and then you can use a flat screw tool to unscrew it.
The fourth method: When you can't bear to twist it, use a hacksaw to cut off the entire screw head, or mix it with aqua regia to corrode the screw head. Of course, this method is quite crude.
The fifth method: When you can't bear to twist it, first burn the head of the screwdriver red on the gas stove, of course, as long as it is on fire. Then quickly press on top of the twisted screw, and wait for a while before you can unscrew it.
The sixth method: When you can't bear to twist the screw, if you have a very small pointed pliers at home, you can use this very small pointed pliers to directly pull out the twisted screw with force.
