Abstract
The invention discloses a special tool for disassembling an anti-theft screw of an iron tower. The special tool comprises a handle, wherein a connecting block is mounted at one end of the handle; a connecting rod is mounted on one side of the connecting block; a fixing groove is formed in one side of the connecting rod; a connecting plate is mounted on one side of the connecting rod; a through hole is formed in the middle of the connecting plate; the through hole is communicated with the fixing groove; a connecting groove is formed in one side of the connecting plate; the connecting groove is communicated with the through hole. By adopting the special tool, a 500 kv anti-theft bolt can be disassembled as a whole, the screw rod of the 500 kv anti-theft bolt is prevented from being retained inside a screw hole, and a 500 kv circuit is prevented from being damaged. The fixing groove (1) of the special tool can be put into the head of the anti-theft bolt when the 500 kv anti-theft bolt is disassembled.
