The invention relates to an anti-falling tool sleeve. The anti-falling tool sleeve comprises a body and insertion bags. The insertion bags are arranged on the body. A connecting portion I is arranged on the upper portion of the body and is provided with connecting holes I. A connecting sleeve is arranged to be of a double-layer structure. The upper edge of the connecting sleeve is sealed. The two sides and the lower edge of the connecting sleeve are open. A connecting portion II is arranged on the lower edge of the connecting sleeve and is provided with connecting holes II. The connecting holes II are matched with the connecting holes I. The connecting holes I are formed between the two connecting holes II. A rotating shaft penetrates through the connecting holes II and the connecting holes I. The two ends of the rotating shaft are fixed through nuts. Potential safety hazards can be reduced when a user works on a tower. Tools and material can be prevented from falling when the user works on the pole and tower. The safety coefficient is increased. Work efficiency is improved. The anti-falling tool sleeve is convenient to move and carry. Meanwhile, the line work level is increased, and safety production of power enterprises is greatly promoted. The anti-falling tool sleeve is simple in structure, high in practicability, safe and reliable and has extremely-great application and popularization value.
