    • A combustion nailer (10) includes a tool housing (12), a combustion source (14) disposed at least partially in the housing and including a valve sleeve (24) reciprocating relative to a cylinder head (42) along a tool axis (A) between a rest position and a pre- firing position, a fuel cell chamber (34) in the housing in operational proximity to the combustion source and dimensioned for accommodating a fuel cell (36), at least one pivot point (56) associated with the fuel cell chamber (34) transverse to the tool axis for facilitating movement of the fuel cell (36) between a non-activated position and an activated position, and at least one actuator (50) pivotable about the pivot point (56) and engaging the valve sleeve (24) at a point (54) closer to the tool axis (A) than to the fuel cell chamber (34) 2 such that movement of the valve sleeve from the rest position to the pre- firing position causes movement of the fuel cell from the non-activated position to the activated position.
    • 燃烧式钉枪(10)包括工具壳体(12),至少部分地设置在壳体中的燃烧源(14),并且包括沿着工具轴线(A)相对于气缸盖(42)往复运动的阀套筒(24) ),所述壳体中的燃料电池室(34)在操作中靠近所述燃烧源并且被设计成用于容纳燃料电池(36),所述至少一个枢转点(56)与 所述燃料电池室(34)横向于所述工具轴线,以便于所述燃料电池(36)在非启动位置和致动位置之间移动;以及至少一个致动器(50)可围绕所述枢转点(56)枢转,以及 在比燃料电池室(34)2更接近工具轴线(A)的点(54)处接合阀套(24),使得阀套从静止位置移动到预燃位置导致运动 的燃料电池从非激活位置到激活位置。
