The invention discloses a telescopic lifting tool. The telescopic lifting tool comprises a top box body. Symmetrical steel cable containing inner cavities are formed in the top box body. A middle inner cavity located in the top box body is formed between the steel cable containing inner cavities. Symmetrical penetrating inner cavities are formed in the lower end wall of the middle inner cavity ina communicated manner. The penetrating inner cavities are formed in an up-down penetrating manner. A bottom box body is arranged on the lower side of the top box body. Symmetrical side fixing blocks are fixedly arranged on the end surfaces of the two sides of the bottom box body. A box body is slidably clamped into the bottom box body. The interior of the box body is of a hollow structure. Symmetrical transmission inner cavities are formed in the box body. A plurality of unwinding devices are arranged in the steel cable containing inner cavities and the middle inner cavity. The penetrating inner cavities are formed in the unwinding devices. By the adoption of the telescopic lifting tool, the device can correspondingly enable the bottom box body and the box body to perform telescopic lifting, and the two stages of the bottom box body and the box body are utilized, so that articles can be hung through matching hooks and suspension hooks correspondingly, and good firmness is achieved.
