Description
本創作主要係揭示一種氣動工具，尤指具有延伸裝置之氣動工具。This creation mainly discloses a pneumatic tool, especially a pneumatic tool with an extension device.
請參閱我國專利第M460752 號之「氣動式棘輪扳手」專利案，其為一種氣動式棘輪扳手，其包含一傳動機構、一氣動馬達及一棘輪接頭。傳動機構包含一傳動軸、一離合座及二擊錘環，傳動軸具有一驅動端及自驅動端延伸的一傳動端，驅動端的外周面上形成有相對配置的二凸砧，傳動端則軸向凸設有一偏心軸，離合座可旋轉地套設於驅動端，離合座內設有相互平行配置的二限位梢，擊錘環分別樞設於不相同的其中一限位梢且對應凸砧配置，氣動馬達連接離合座以帶動離合座旋轉，棘輪接頭連接偏心軸且被傳動軸帶動。Please refer to the "Pneumatic Ratchet Wrench" patent of the Chinese Patent No. M460752, which is a pneumatic ratchet wrench comprising a transmission mechanism, a pneumatic motor and a ratchet joint. The transmission mechanism comprises a transmission shaft, a clutch seat and a two-stroke hammer ring. The transmission shaft has a driving end and a driving end extending from the driving end. The outer peripheral surface of the driving end is formed with two opposite anvils, and the transmission end is a shaft.
