Description
Double torsion spring is a coil spring. Torsion springs can store and release angular energy or statically fix a device by rotating the force arm around the central axis of the spring body. These springs are usually tight, but there is a pitch between the coils to reduce friction. They create resistance to rotation or rotational external forces. According to the application requirements, the rotation direction (clockwise or counterclockwise) of the torsion spring is designed to determine the rotation direction of the spring.
