Shock-proof device for main rotating shaft of phonograph disc

The utility model discloses an anti-vibration device for a main rotating shaft of a phonograph disc, which belongs to the technical field of phonographs and comprises a rotating shaft sleeve, sliding grooves are formed in the inner walls of the two sides of the rotating shaft sleeve, sliding blocks are connected in the two sliding grooves in a sliding manner, a shaft seat is fixedly connected between the two sliding blocks, a rotating shaft body is mounted at the top end of the shaft seat, and the rotating shaft body is fixedly connected with the rotating shaft sleeve. When the rotating shaft body is vibrated by the disc, the shaft seat drives the sliding block to slide on the guide rod, and a half part of the sliding block slides in the sliding groove, so that a series of friction is generated, and the sliding block is driven by the shaft seat to slide on the guide rod. The vibration of the rotating shaft body can be relieved through friction, the vibration reduction effect can be further improved under the
