[0002] A satellite main structure contains a large number of plane frames, space trusses, sandwich plates and stringers. A large number of plate nuts are used to provide mechanical interfaces during assembly of such structures. The commonly used plate nuts are double-ear structures, with a threaded hole in the center and rivet holes on both sides. Rivets are used to connect the mounting parts of the structure. Common local structure forms are shown in FIG. 1. The rivets used include pull rivets and press rivets. The press rivets have two forms: using a special tool to clamp the rivet and using a small hammer to knock the rivet. The pull rivet and the clamped rivet both require the use of special tools, and the tool size is large, which is greatly affected by the structure form of the mounting part and the operation space. The riveting installation method using a small hammer to knock has stronger applicability and is widely used in the riveting operation of the satellite main structure. Figure 1

[0012] Preferably, the cross section of the top anvil screw is a cross-shaped structure, and the second base hole does not allow the top anvil screw to pass through.

[0013] Preferably, the top anvil sleeve has different specifications, so that different specifications of rivets can be quickly adapted by replacing top anvil sleeves of different specifications.

[0014] Preferably, the base is made of 45 steel.

[0015] Preferably, the center locking screw, the top anvil locking nut, the support plate nut and the rivet are standard parts, and the structure plate is a self-component of a satellite main structure.

[0016] Preferably, the side of the top anvil sleeve in contact with the rivet is a plane.
