description The invention provides a mechanical retaining device for a magnetic control mechanism, which comprises an unlocking electromagnet, the unlocking electromagnet is connected with the lower end of a spring pull rod, the upper end of the spring pull rod is rotatably connected with one end of an elastic pull rod, the other end of the elastic pull rod is connected with one end of a retaining wedge, and the other end of the retaining wedge is rotatably connected with the spring pull rod. The spring pull rod and the elastic pull rod drive the retaining wedge block to rotate clockwise or anticlockwise; the invention further provides a mechanical holding method for the magnetic control mechanism. According to the invention, if small-gap separation of the movable iron core and the static iron core of the magnetic control mechanism is caused by non-opening operation such as strong vibration and the like in a closing state, so that the suction force is reduced and cannot be handled, the movable iron core can be kept at a
