[0002] A double-position screw is a threaded connection that has two thread structures, that is, two different thread positions are set on the same screw so that two movements can be performed simultaneously when loosening or tightening. Due to the design of the double-position screw, the two thread structures act in different directions, so they can rotate relatively independently, thereby achieving convenient operation and efficient connection effects.
