Two ends of the inner hole of the novel yo-yo hammer are respectively provided with a groove hole with the height of 30mm and the thickness of 5mm to form an I-shaped hole.

The sealing ring is a circular ring plate with a through hole, the inner diameter of the through hole is the same as the small diameter of an I-shaped hole in the novel Youyu hammer, and the outer diameter of the sealing plate is the same as the big diameter of the I-shaped hole.

Compared with the prior art, the beneficial effects of the utility model are that:

1) a unload blast furnace tuyere small sleeve instrument has adopted spherical ball rolling friction to replace partial sliding friction power for the required thrust of novel long hammer reduces, and working strength reduces, and workman work efficiency increases.

2) The novel long hammer of the tool for dismounting the small tuyere sleeve of the blast furnace is filled with glycerol lubricating ester, so that the sliding friction force of the contact part of the novel long hammer and a sliding rod in the sliding process is reduced, the working efficiency of the tool for dismounting the small tuyere sleeve of the blast furnace is increased, and the labor intensity of workers is reduced.

3) The tool for unloading the blast furnace tuyere small sleeve reduces the use requirement of the sliding rod, increases the matching degree of the sliding rod and the swing hammer, saves the maintenance work of the sliding rod, saves the maintenance time and saves the maintenance cost.
