Tool sleeve preventing high-altitude falling of tool

The invention relates to a tool sleeve preventing high-altitude falling of a tool. The tool sleeve preventing the high-altitude falling of the tool comprises a leather sheath (4), wherein the tool is inserted to an inserting hole (1) on the leather sheath (4). The tool sleeve preventing the high-altitude falling of the tool is characterized by further comprising a connecting part, wherein one end of the connecting part is hinged to the leather sheath (4), and accordingly the connecting part and the leather sheath (4) can rotate mutually. Trials demonstrate that after the tool sleeve preventing the high-altitude falling of the tool is adopted, the tool falling times are decreased from 48.57% before movement to 0 after movement, and a phenomenon that the tool falls down and accordingly ground workers are injured does not occur.
