The invention discloses a shielding part. The shielding part comprises an assembly part, a shielding block, a guide shaft and a limiting part. An assembly groove is formed in the center of the assembly part. The shielding block can be inserted into the assembly groove, a guide through groove is formed in the shielding block, and the front end of the shielding block is located outside the assembly groove. The guide shaft penetrates through the assembly groove through a first guide hole in the assembly groove and is matched with the guide through groove in an inserted mode. The limiting part penetrates through the assembly groove and a first limiting hole in the guide through groove through a second guide hole in the assembly groove. The front end of the shielding block is limited in the position where an equipment operating hole is shielded through the limiting part, so that an unlocking shaft is prevented from being inserted into the operating hole at will; under the condition that the operating hole is not allowed to be operated, an operator cannot insert the unlocking shaft into the operating hole, then an equipment operating shaft in the operating hole cannot be operated, maloperation of the operator on the operating hole can be effectively avoided, accidents caused by maloperation are avoided, and safety operation of power equipment is guaranteed.
