Buffering connector

The invention relates to a buffering connector, which comprises a connector body and a steel ball, wherein a ball seat is installed on the inner lower part of the connector body, the steel ball is installed on the ball seat, a throttling port is arranged above the steel ball, a retainer ring is installed below the ball seat, the throttling port is a double-faced notch-type throttling port, and the area of the throttling port is 0.07mm2 to 85mm2. According to the buffering connector, as a single-direction throttling valve is embedded inside a connector of a cavity with a rod of an overturning oil cylinder, when the overturning oil cylinder turns over the gravity of a cab, automatic descent of the cab can be realized, the back pressure is increased during the automatic descending process of the cab, the automatic descending process of the cab is stable and is free from impact, no throttling exists during the returning process of the cab, the operation torque and the operation times can be reduced, and further,
