Abstract
An apparatus having a conductor passing through a magnetic yoke and is mounted on the bracket, in which the magnetic yoke is fixed on the bracket as well. Above the conductor, a shaft is mounted on the top of the bracket. A push rod is mounted on the shaft and rotates with the shaft about the bracket. An armature, spaced apart from the magnetic yoke, is fixed on the push rod. Adjusting mechanisms are mounted on both sides of the shaft between the push rod and the bracket. Within the adjusting mechanism, a torsion spring is around the shaft. An adjusting rod is provided with a plurality of adjusting surfaces which makes contact with the adjusting mechanism. A spring force of the torsion spring enables the push rod to rotate towards a direction which makes the armature and the magnetic yoke separate.
