The invention relates to a quick positioning device for a femoral-nail entry point. The quick positioning device for the femoral-nail entry point comprises a rectangular metal frame, a fixing rod anda connecting rod, wherein the fixing rod is connected on an operating table, the two ends of the connecting rod are connected with the rectangular metal frame and the fixing rod through angle adjusting pieces capable of adjusting the angle respectively, and meanwhile guiding needle grooves and a needle threading groove which are located in the same place are formed in the rectangular metal frame,wherein guiding needles conveniently move in the guiding needle grooves and the needle threading groove. The quick positioning device for the femoral-nail entry point has the advantages that quick positioning of a needle inserting point can be achieved before operating or in the operating process through the positioning device, the puncturing number of times for patient leg positioning during needling inserting is decreased, and patient pains are reduced; meanwhile, the height and the angle of device are adjusted for unsuitable positions, and the quick positioning device is simple in structureand quite convenient to assemble and disassemble.
