Abstract

A fastener driving tool (10), which relates to a power tool, includes a support cylinder (23), a striking unit (2A) having a driving piston (21) and a striker (22), a driving gas chamber (24) in fluid communication with a discharge volume, a lifting assembly (40) configured to drive the striking unit to move in the first direction, and a gas supplementation unit (2B) disposed inside the support cylinder; the gas supplementation unit includes a gas supplementation piston (25) and a gas supplementation chamber (26). When the striking unit moves in the second direction, the volume of the gas supplementation chamber decreases, allowing the gas in the gas supplementation chamber to enter the driving gas chamber. When the striking unit (2A) moves in the first direction, the volume of the gas supplementation chamber (26) increases so that the ambient air may enter the gas supplementation chamber (26). The gas supplementation chamber (26) realizes gas supplementation to the driving gas chamber, thereby ensuring the nailing effect.
