Ultrasonic cleaning protection device

The utility model relates to the technical field of ultrasonic cleaning, and discloses an ultrasonic cleaning protection device which comprises a base, a storage box and an ultrasonic cleaning machine body, the storage box is fixedly installed on the upper surface of the base, and the ultrasonic cleaning machine body is placed in the storage box. A supporting mechanism corresponding to the ultrasonic cleaning machine body is arranged in the base and used for keeping the ultrasonic cleaning machine body stable. In the downward moving process of the ultrasonic cleaning machine body, a toothed plate is driven to move downwards, so that the toothed plate drives a piston to slide in an air chamber, damping and buffering are conducted through air pressure, meanwhile, the toothed plate drives a gear to rotate, the toothed plate rotates to drive a fixing plate to move upwards, and then a rubber plate is extruded through a connecting rod; due to the fact that the rubber plate has elasticity, the ultrasonic cleaning ma
