This invention provides a crystal rotation lift and pulls equipment that has damping. It is consisted of flanged shaft, flexibie disc, conical surface rotary table, friction cone, seed rod, supporting enclosure and motor. Two flexible discs are fixed between the lower end of the flanged shaft and the upper end of the conical surface rotary table separately, the keep a certain pressure. The friction cone is fixed at the place of conical surface of conical surface roa\tary table, the lower end of the friction cone is connecdted with seed rod, the conical surface rotary table is fixed on the supporting enclosure by bearing, and it can rotate freely. The supporting enclosure is fixed on the motor. This invention transforms the fixed coupling direct drive between the motor and the seed rod into friction drive. It can bring relative slip, so it can eliminate the torque caused by inertia of the motor, and then it will work as active protecion equipment.
