The starting motor 6 can drive the guide rod 7 to rotate, and then drive the moving block 8 to move, thereby driving the motor 9 to move left and right, and can move the limit claw 13 to a specified position. The limit claw 13 is driven downward by the first hydraulic telescopic rod 11 to grab the mechanical structure.
