<P>PROBLEM TO BE SOLVED: To provide a connection auxiliary tool for a hot stick capable of adjusting a tilt angle of a tip tool at the base end of the hot stick. <P>SOLUTION: A connection auxiliary tool 10 can attach/detach a tip tool 1t having a first rosette-shaped part 11t to/from the tip part. A hot stick Hs comprises an operation rod 1, a first revolving shaft 12, and a handle 2. The first revolving shaft 12 is rotatably held inside the operation rod 1. The handle 2 is disposed at the base end part of the operation rod 1, and can transmit rotation to the first revolving shaft 12. The connection auxiliary tool 10 comprises a moving nut 3, a rack 31, a pinion 41, a second revolving shaft 42, and a tool fitting tool 5. The moving nut 3 is held by a top metal fitting 15 to convert a rotary movement of the first revolving shaft 12 to a forward/backward movement. The rack 31 and the pinion 41 convert a forward/backward movement of the moving nut 3 to a rotary movement of the second revolving shaft 42. The tool fitting tool 5 whose base end part is fixed to the second revolving shaft 42 has a second rosette-shaped part 52b, at its tip part, capable of connecting the first rosette-shaped part 11t. <P>COPYRIGHT: (C)2013,JPO&INPIT |
