Since the rotating shaft 312 is fixedly connected to the through hole 316, when the rotating shaft 312 rotates, it can drive the turntable 313 to rotate. At this time, the arc-shaped through-groove 314 on the turntable 313 causes the connecting rod 315 to slide outward along the through-groove 314, thereby pushing the slide rod 32 to extend. When the clamping block clamps the inner wall of the pipe, the driving motor 311 is turned off. At this time, the symmetrical clamping arms 2 evenly support the pipe, thereby improving the stability of the lifting. Then the crane is started for lifting and transportation.
