The electric telescopic rod 4, the movable connecting ring 61, the movable groove 92 and the clamping block 93 are symmetrically arranged in two to form a relatively balanced and clamping structure with strong force. The front and rear outer surfaces of the movable plate 6 are fixedly connected with an axial rod for connecting the movable plate 6 and the movable connecting ring 61 for movement. The bottom surface of the boom 1 is fixedly connected with an electric telescopic hydraulic rod 2 for adjusting the height of the boom 1.
