[0002] In the maintenance of the power system, the power system maintenance personnel often use a tool called a link rod. The link rod, that is, the switch rod, is a rod structure, which is mainly composed of three parts: a working head, an insulating rod and a handle. The power system maintenance personnel use it to close or open the high-voltage switch. Due to the insulating properties of the link rod, sometimes the power maintenance personnel also use the link rod to pick up foreign objects on the power equipment, but due to the lack of blocking protection, sometimes the foreign objects picked up will slide down the link rod and hit the staff. In order to solve the above problems, the utility model patent with announcement number CN208478167U discloses a link rod, which prevents rain from sliding down the link rod by installing a rain cover on the link rod.
