Abstract

The invention discloses a riveting device which comprises an inner guide sleeve, an outer sleeve, a retaining ring and a driver. A push rod is inserted in the inner guide sleeve. The outer guide sleeve sleeves the inner guide sleeve. The retaining ring is positioned in the outer guide sleeve, and is next to the outer guide sleeve. A screw is inserted in the outer guide sleeve and the retaining ring. The body of the screw extends out of the outer guide sleeve, and is screwed to a rivet nut. The head of the screw is positioned in the inner guide sleeve, and is next to a part between the retaining ring and the push rod. The driver is combined with the inner guide sleeve, and uses the inner guide sleeve to drive the inner guide sleeve, the push rod, the outer guide sleeve, the retaining ring and the screw to synchronously move with the rivet nut on the driver to rivet the rivet nut. The screw is fixed by the push rod, the retaining ring and the outer guide sleeve, so that the riveting device is prevented from being limited by the size or the shape of the screw head of the screw.

Description

technical field [0001] The present invention relates to a riveting device, in particular to a riveting device capable of using screws with any screw heads. Background technique [0002] The current cap riveting tool needs to be equipped with a "mandrel" and then the cap is turned clockwise to lock it on the rod, and then the user applies force to the tool to make the rod move backwards to achieve riveting of the cap the goal of. After the riveting is completed, the pull cap will be fixed on the workpiece, and the tooth rod needs to be turned counterclockwise to separate the tooth rod and the pull cap. At present, the cap pulling tools on the market all use special tooth sticks, which means that each manufacturer has its own tooth stick design. Because the tooth stick needs to match the thread specifications of the pull cap, sometimes the tooth stick matched with the tool is not suitable for the pull cap on the user's hand. The most obvious example is that the user's tool ...
