The invention discloses a mobile phone charging support frame which mainly comprises a fixing plate, a plurality of suckers, an upper clamp plate and a lower clamp plate. The multiple suckers are fixed to one side of the fixing plate, a plurality of concave-convex portions are arranged at one end of the upper clamp plate and one end of the lower clamp plate, the upper clamp plate is staggered from the lower clamp plate, the concave-convex portions are meshed with one another, a support seat is arranged in the middle of the other side of the fixing plate, a rotary shaft is arranged on the support seat, the upper clamp plate and the lower clamp plate are connected with the support seat by the rotary shaft and can rotate around the rotary shaft, and locking nuts are arranged on two sides of the rotary shaft and can be screwed down, so that the upper clamp plate and the lower clamp plate can be relatively fixedly positioned, and a mobile phone can be clamped by the upper clamp plate and the lower clamp plate. The mobile phone charging support frame has the advantages that the support frame can be sucked on a wall made of ceramic tiles via the suckers of the fixing plate, the mobile phone can be clamped and supported by the upper clamp plate and the lower clamp plate, can be fixed by the aid of the locking nuts and can be sucked on the wall or furniture near a socket, accordingly, the charging safety of the mobile phone can be improved, and the service life of the mobile phone can be prolonged.
