Abstract
A repeating nail-feeding structure for pneumatic nailing machine, installed in a pneumatic nailing machine, includes an air stream guiding tube, automatic return cylinder, and shifting element. The tube enables working air stream from the machine to enter the cylinder, thereby a piston stein of the cylinder is driven to a retracted position. The piston stein is returned to an extended position by the pressing of a return spring within the cylinder. The shifting element is fixed to the piston stein and provided with a shifting lever. The shifting lever is moved along with the piston stein to advance the strip nail of the machine. Thereby, when the nail is ejected, the strip nail is advanced simultaneously by the discharged working air stream. The requirement of extensive use is fulfilled due to no limitation to length of the strip nail and successive nail-feeding capability.
