The invention provides an antiskid climber which is simple in structure, convenient to operate, reliable and stable. The antiskid climber comprises a movable hook, a guide tube, a connecting rod and a pedal plate, wherein the movable hook is in a J shape, one end of the movable hook is movably connected in the guide tube, the guide tube is connected to the connecting rod, and the connecting rod is fixedly connected to the pedal plate, sliding grooves are formed in the inner circular arc face of the movable hook, and antiskid mechanisms are arranged in the sliding grooves. According to the antiskid climber, the antiskid mechanisms are arranged in the movable hook, the friction force between the antiskid climber and an electric pole is enlarged through the antiskid mechanisms, the normal working of maintenance personnel in rain and other severer conditions is achieved, and the antiskid climber is safe and reliable.
