Integrated tailpiece for cello

Abstract

The utility model discloses a violoncello integrated tailpiece which comprises a violoncello integrated tailpiece body and an insertion connection groove arranged on the side surface of the violoncello integrated tailpiece body. A rubber air bag ring is arranged on the side face of the middle of the inserting connecting groove, a built-in telescopic connecting body is arranged at the bottom of the stirring and extruding rotary knob column, the stirring and extruding rotary knob column is rotationally connected with the built-in telescopic connecting body through a rotating shaft, and a linkage ventilation pipe is arranged at the bottom of the built-in telescopic connecting body. A linkage ventilation pipe is communicated with a rubber air bag ring, and a built-in telescopic connecting body can be extruded by stirring a stirring and extruding knob column, so that air in the built-in telescopic connecting body enters the rubber air bag ring to reduce the hole diameter of an insertion connecting groove; after the tailpiece is improved, the inner diameter of the inserting connection groove can be reduced after inserting connection and installation are completed, so that the inserting connection groove can be attached to the installation column more tightly, and the phenomenon that due to the fact that gaps exist in the installation position, the tailpiece shakes, and the use experience is affected is effectively avoided.
