Anti-impact structure of vacuum pump

The utility model provides an anti-impact structure of a vacuum pump, and belongs to the technical field of anti-impact structures of vacuum pumps. The vacuum pump comprises a vacuum pump body, a motor base rotationally connected with the vacuum pump body and a fixed base arranged below the vacuum pump body. Through cooperation of a fixed frame, a secondary buffer device and the like, under the gravity effect of a vacuum pump body, a telescopic sleeve begins to slide downwards, at the moment, a limiting sliding block can correspondingly slide upwards along a limiting rod, and under driving of a connecting rod, a sliding piece can get close to the two sides of a sliding groove, so that multi-stage buffer of the device is achieved; impact force and vibration generated by high-speed rotation of the three-blade rotor and gas compression can apply acting force in the direction of the sliding groove to the vacuum pump body, the telescopic rod can conduct short-distance displacement on the sliding rod, and the limit
