Double-disc self-locking relieving mechanism

The invention discloses a double-disc self-locking relieving mechanism which comprises a motor shaft and a brake disc, the motor shaft is connected with the brake disc, and the motor shaft is connected with a limiting assembly used for limiting the brake disc and an adjustable assembly used for relieving the limiting assembly. The adjustable assembly comprises two relieving pull rods, two double-disc driving rods and a driving block. The device is simple in structure and reasonable in design, the pull rope is utilized to pull the driving block, the driving block conducts translational motion in the second direction along the guide rod, the relieving reset spring is compressed, the driving block pushes the two double-disc driving rods to rotate, the two double-disc gaskets are lifted, accordingly, the two relieving pull rods are pulled, the two relieving pull rods pull the armature, the brake disc is in a movable state, and the braking effect is improved. And the operation piece is led to the outer side of the
