Recoverer for electromagnet with adjustable magnetic force

The utility model relates to a recoverer for an electromagnet with adjustable magnetic force, comprising a charging port, an expansion link, a multi-gear switch, a chargeable battery, fixed links, a solenoid coil, an iron core, a cylindrical shell, and a mop rod, the expansion link is positioned at the upper portion of the whole structure, a lower end is connected with the upper end of the mop rod, the lower end of the mop rod is fixedly connected with the cylindrical shell, the mop rod is provided with the multi-gear switch, the chargeable battery, and the charging port, the multi-gear switch is positioned below the expansion link, the chargeable battery is positioned below the multi-gear switch, the charging port is positioned below the chargeable battery, and the mop rod and the solenoid coil are fixedly connected by two fixed links. The beneficial effects are that: the resistance that enters to a circuit is changed by the multi-gear switch, so as to change electric current, and further change the magnetic force of an electromagnet, and the selectivity of magnetic force range is improved greatly; a handle adopts an expansion link structure, so that the length of the handle is adjustable, the use of different crowds can be met, and the comfort degree and flexibility of the use are enhanced.
