The telescopic rod can be extended and retracted, and the telescopic rod can prevent the protective plate from being offset. The cushion can be made of rubber material, and the cushion can enhance the buffering effect of the protective plate. At the same time, the cushion and the protective plate form a snap-fit ​​structure. If material falls on the cushion, the cushion can be removed and replaced, so as to achieve the purpose of fixing the lifting transfer machine to protect the base. BRIEF DESCRIPTION OF THE DRAWINGS
