The invention discloses an anti-theft device for escalator leading-edge plate overhauling. The anti-theft device for escalator leading-edge plate overhauling comprises a leading-edge plate and fixed to an escalator truss. The anti-theft overhauling device further comprises a balance rod, a safety switch and a fixing plate. The left end of the balance rod is bent upwards and stretches to form a vertical rod. The fixing plate is fixedly connected to the escalator truss. The portion, close to the left end, of the balance rod and the fixing plate are provided with two through holes respectively. The balance rod and the fixing plate are movably connected with each other through the through holes. The upper end of the vertical rod makes contact with the bottom wall of the leading-edge plate when the leading-edge plate is closed. The safety switch is located under the position, close to the bottom wall of the right side of the through hole, of the balance rod. The anti-theft device for escalator leading-edge plate overhauling is simple in overall structure and convenient to mount, and the safety switch cannot be pressed and damaged and is long in service life and more sensitive and effective compared with general spring switches, so that safe overhauling and the anti-theft function can be achieved safely and effectively.
