The invention relates to a riveting gun, in particular to a rivet withdrawing device for improving rivet withdrawing precision of the riveting gun. According to the composition, an oil piston nut is embedded in an oil piston, threads are arranged on a rod head of an oil piston rod, an annular plug groove is formed in the threaded rod head of the oil piston rod, a rivet clamping assembly is arranged at the tail end of the oil piston rod, and a layer of positioning ring is arranged on a round head of a rivet withdrawing pipe. A gas plugging ring is arranged on the inner side face of the positioning ring of the round head of the rivet withdrawing pipe, a funnel-shaped protruding head is arranged at the front end of the positioning ring of the round head of the rivet withdrawing pipe, a plug is arranged at the tail end of the positioning ring, a turning hinge is arranged on the top of the rivet withdrawing pipe, a ring fixing groove is formed in the inner side face of the turning hinge of the rivet withdrawing pipe, and two symmetrical vent holes are formed in the pipe face of the rivet withdrawing pipe. A rivet outlet pipe head of the rivet withdrawing pipe extends into a discharging pipe to be fixed. By means of the rivet withdrawing device for improving the rivet withdrawing precision of the riveting gun, the problems that a piston rod and a rivet withdrawing pipe of a traditional riveting gun are complex in manufacturing process, high in cost, difficult to install and low in precision are solved, and the situation that due to the fact that the rivet withdrawing precision of the piston rod is low, rivets get stuck in the riveting gun is avoided.
Description
technical field [0001] The invention relates to a rivet gun, in particular to a nail stripping device for improving the stripping precision of the rivet gun. Background technique [0002] With the improvement of production and industrial technology, people cannot do without the use of rivet guns in the process of production and construction, and use rivets to fasten and rive all kinds of metal sheets, pipes, etc. The rivet guns on the market generally use a combination of air pressure and oil pressure. To realize the riveting and stripping work of rivets, the working principle and overall structure of the existing rivet guns are too complicated. Among them, there are problems of complicated manufacturing process, difficult installation and low precision between the piston rod of the rivet gun and the stripping tube. The low precision of the combination of the piston rod and the nail ejector tube will cause the offset to affect the situation of the staples during the nail eje...
