Power-assisted mechanical arm with anti-shake device

The power-assisted mechanical arm with the anti-shake device comprises a mechanical arm base, the tail end of the mechanical arm base is perpendicularly connected with a connecting supporting rod, a locking and rotating mechanism is installed at the bottom of the connecting supporting rod, and the locking and rotating mechanism internally comprises rotating connecting rods attached to the two sides of the outer wall of the connecting supporting rod. Connecting shafts are nested in the rotary connecting rod and the connecting supporting rod through formed shaft holes, and telescopic rods are connected to the left sides of the connecting shafts. According to the device, the safety of workers during cargo carrying can be effectively protected by arranging the protection mechanism, the problem that the adsorption force of a suction cup is reduced in the long-term use process is solved, meanwhile, the surfaces of cargoes are not of a completely-flat structure, and a protection plate is arranged on one side of the
