"Upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0019] Referring to Figures 1-5 As shown, this application provides a portable chain block, including: a chain block body 1, a chain 2 is connected to the chain block body 1, a sling 3 is connected to the end of the chain 2, a connecting block 4 is fixedly connected to the chain block body 1, an extraction device is arranged outside the connecting block 4, and the extraction device is snap-connected to the connecting block 4; the extraction device includes a first box body 5 and a second box body 6 that are slidably connected, the first box body 5 is sleeved outside the connecting block 4, and the second box body 6 is sleeved outside the first box body 5 and is slidably connected to the first box body 5. The bottom of the connecting block 4 is a wedge-shaped structure, and the first box body 5 is a hollow structure with a through hole provided on its bottom plate, which is snap-connected to the wedge-shaped structure at the bottom of the connecting block 4.

[0020] To further optimize the above technical solution, the top plate and the side edges of the bottom plate of the first box body 5 protrude to form snap-fit strips, and a limiting function is formed between a convex block provided at the bottom of the second box body 6 and the snap-fit strips. A spring 7 is arranged between the connecting block 4 and the first box body 5, one end of the spring 7 is fixedly connected to the connecting block 4, and the other end is fixedly connected to the inner wall of the first box body 5. The spring 7 plays a buffering role. Both ends of the spring 7 are welded to ensure the connection strength.

[0021] To further optimize the above technical solution, a handle 8 is hingedly arranged on the second box body 6. A storage hook 9 is fixedly connected to one side of the second box body 6, and a fixing post 10 is arranged on the second box body 6. The storage hook 9 is wound around the fixing post 10. The handle 8 is rotatably hinged on the outer side wall of the second box body 6, and a concave-convex surface for holding is installed on the handle 8 to increase the friction force, facilitating personnel to lift the chain block and preventing it from slipping.

[0022] In use, first hang the chain 2 and the sling 3 on the storage hook 9, wind the storage hook 9 around the fixed column 10 to an appropriate length, and lift the second box body 6 through the handle 8.
