SHAFT CENTER RETAINER OF HIGH SPEED ROTARY WRENCH AND HIGH SPEED ROTARY WRENCH WITH APPLICATION OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a shaft center retainer of a high speed rotary wrench and a high speed rotary wrench with application of the retainer.SOLUTION: A shaft center retainer of a high speed rotary wrench is fitted to a transmission groove of a high speed rotary wrench, the transmission groove is formed between a drive hole and a transmission hole, the drive hole is so formed on the high speed rotary wrench as to be extended along a first axis, a drive unit of the high speed rotary wrench is fitted to the drive hole whereby a fastener can be driven, and a transmission gear of the high speed rotary wrench is movably fitted to the transmission hole of the main body. The shaft center retainer of the high speed rotary wrench has a shaft hole, the shaft hole penetrates one side of the shaft center retainer along the second axis. After the shaft center retainer is fitted to the transmission groove of the high speed rotary wrench, the second axis and the first axis of the drive hole are so made as to cross and to be perpendicular to each other, the transmission gear of the high rotary wrench is extended in the shaft hole and is connected to the drive unit to each other.SELECTED DRAWING: Figure 1
