[0002] Torsional spring, as a very common elastic element, due to its unique performance characteristics, plays an irreplaceable role in various mechanical equipment, and is widely used in switches, clamps, door locks and numerous precision instrument devices. It uses its torsional elastic force to provide necessary tension or locking function for these devices, ensuring the stability and reliability of mechanical operation. However, in the actual assembly process of torsional spring, due to its special shape, it often presents a complex spiral shape and has a certain elastic recovery force, which makes it difficult to place the torsional spring in the predetermined position as easily and accurately as other regular shaped parts.
[0003] In order to correctly assemble the torsional spring in place, the operator usually needs to use a special tool to adjust the torsional spring to the specified torque state, and then align the adjusted torsional spring with the marked position on the target component. This process requires very high precision and patience, because even a small angle deviation may cause the torsional spring to malfunction or even damage the entire mechanical equipment.
