Antiskid musical instrument base

The utility model comprises a base whose middle part is provided with a through hole. The upper part of the through hole is expanded with a big hole and the joint face between the big hole and the through bole is a pyramidal face. The utility model comprises a ball head bolt which comprises a ball head part and a bolt part. The top end of the ball head part is provided with a screwdriver slot. Most of the ball head part of the ball head bolt is imbedded in the big hole of the base and is riveted with the base. The outer surface of the ball head part is in contact with the inner surface of the big hole of the base and the joint face. The utility model comprises a rubber non-skid mat which is fixedly connected with the bottom of the base. While in use, the ball head bolt is in bolted connection with the tail cone at the bottom of a violone or cello. The rubber non-skid mat is in flat contact with the ground and the ball head part of the ball head bolt can rotate in the big hole of the base, which meets the needs of the angular change of the violone or cello during performance and ensures that the body of the violone or cello can not move so that a player can fully display the expressive force of the music without damaging the ground and other supports.
