The invention discloses a magnetic crane with built-in reinforced anti-friction supporting legs. The magnetic crane with the built-in reinforced anti-friction supporting legs comprises a magnetic crane body and supporting legs, wherein the magnetic crane body comprises a base and a permanent magnet arranged in the base; and a transmission mechanism used for driving the permanent magnet to rotate is arranged in the base, one end of the transmission mechanism derives a rotating shaft out of the base, a handle is arranged at one end of the base, and the handle is connected with the rotating shaft. Two containing slots are formed in two sides of the lower end of the base in a symmetrical mode, rotating seats are arranged on the inner walls of one sides of the containing slots, the supporting legs are rotatably arranged at one ends of the rotating seats, and the top ends of the supporting legs are rotatably connected with the rotating seats. Foot pads are arranged at the bottom ends of thesupporting legs in a sleeved mode, clamping slots sunken inwards are formed in the foot pads, and the bottom ends of the supporting legs are led into the clamping slots of the foot pads. According tothe magnetic crane with the built-in reinforced anti-friction supporting legs, the magnetic crane can be supported, the wear on the bottom of the magnetic crane is avoided, and the suction of a work surface is affected.
