Abstract
A barrel unit of a pneumatic nail driving device includes a base plate with a pair of hooking lugs. An elongated cover plate is superimposed on and is pivoted to a rear portion of the base plate, and has a pair of pivot ears, a pair of abutment tabs projecting sidewise respectively from the pivot ears, and a pair of shoulder disposed behind the hooking lugs of the base plate. An operating lever has a pair of pivot ears mounted pivotally on the pivot ears of the cover plate in such a manner that the pivot ears of the operating lever slidably and respectively contact the abutment tabs, and a U-shaped clasper pivotally connected to the operating lever. After disposing the clasper around the hooking lugs, rearward pivotal action of the operating lever results in engagement between the clasper and the hooking lugs and subsequently causes tight engagement between the pivot ears of the operating lever and the abutment tabs, and tight engagement between the shoulders and the hooking lugs.
