The invention relates to a rudderpost connecting structure, in particular to a ceramic-based composite rudderpost connecting structure, a hole forming tool of the ceramic-based composite rudderpost connecting structure and a manufacturing method of a riveting hole. The technical problem that reliable connection between an existing ceramic-based composite rudder shaft and a rudder body is difficult to achieve is solved. The rudder shaft connecting structure comprises a rudder body and a rudder shaft. The rudder body comprises a rudder shaft reducing sleeve arranged on the rudder shaft in a sleeving mode, a semi-arc-shaped gasket assembly, a first arc-shaped gasket, a second arc-shaped gasket, a skin assembly and a rudder shaft spanwise box-shaped piece, wherein the rudder shaft reducing sleeve is sequentially sleeved with the semi-arc-shaped gasket assembly, the first arc-shaped gasket, the second arc-shaped gasket and the skin assembly from inside to outside, and the rudder shaft spanwise box-shaped piece is connected with the bottom face of the rudder shaft reducing sleeve. The rudder shaft reducing sleeve comprises a semicircular curved surface structural plate attached to the rudder shaft and a plane bottom plate making contact with the bottom face of the rudder shaft. The semi-arc-shaped gasket assembly comprises a first semi-arc-shaped gasket and a second semi-arc-shaped gasket; the skin assembly comprises a first skin and a second skin; and the rudder shaft and the rudder body are riveted into a whole through a pin. The invention further provides a drilling tool and a riveting hole manufacturing method for the rudder shaft connecting structure.
