An adjustment mechanism is provided inside the suspension rod 25, and the adjustment mechanism is used to adjust the center of gravity of the suspension rod 25 to maintain the stability of the suspension rod 25;

[0038] Through the structural design of the suspension rod 25, the suspension rod 25 can be lifted in the process of transferring the workpiece, so as to shorten the length of the suspension rod 25 under the lifting frame 21, thereby reducing the shaking amplitude of the workpiece during transfer and ensuring the stable movement of the workpiece. During operation, when the galvanizing of the workpiece is completed, the lifting frame 21 will be lifted upward to facilitate the workpiece to be taken out of the galvanizing tank 20. At this time, the two groups of secondary telescopic cylinders 23 are started to lift the connecting plate 24, and the bottom end of the connecting plate 24 is connected with the three groups of suspension rods 25. The three groups of suspension rods 25 will be lifted upward, and the workpiece hung on the hook 27 will move upward with the suspension rod 25, so that the workpiece is closer to the bottom end of the lifting frame 21.

[0040] Through the structural design of the protection mechanism, when the suspension rod 25 pulls the workpiece to move upward, the two sets of protection shells 42 will rotate. When the suspension rod 25 moves to the maximum height, the two sets of protection shells 42 will contact each other and form a relatively sealed shell, thereby protecting the workpiece and isolating the workpiece from the outside world to prevent the workpiece from being disturbed by the external environment. During operation, when the connecting plate 24 drives the suspension rod 25 to lift, the abutment block 35 fixed on the suspension rod 25 will abut against the lifting rod 36 and push the lifting rod 36 to move upward, the second spring 38 will be stretched, and when the lifting rod 36 moves upward, it will drive its bottom end to rotate and move.
