Hand tool with impact drive and speed reducing mechanism |
摘要 |
A power driven tool useful for tightening and loosening a mechanical fastener includes an impact mechanism. Preferably, the tool is pneumatic and includes a ratchet head and an impact device for providing additional torque to the ratchet head. A planetary reduction gear reduces the high output speed of a pneumatic motor for input into the impact device and reduces wear on the impact device.
