A nail gun includes: a housing formed with an accommodating space; a cylinder; a firing assembly capable of moving from an initial position to a firing position; a power output assembly disposed in the accommodating space and used for outputting a driving force; and a drive wheel connected to an output shaft of the power output assembly and used for driving, under the drive of the power output assembly, the firing assembly to move. The drive wheel has a first drive tooth and second drive teeth, the radius of the addendum circle of the first drive tooth is less than the radius of the addendum circle of a second drive tooth, the first drive tooth is a drive tooth disposed at a start end of the drive wheel, and the first drive tooth meshes with the firing assembly when the drive wheel starts driving the firing assembly to reset.

Nail gun

A fastening tool includes a housing, a magazine, a striking assembly, a trigger assembly, and a brake assembly, where the housing is formed with an accommodation space, the magazine accommodates a fastener, and the striking assembly is accommodated in the accommodation space and includes a striker, where the striker is configured to move along a striking direction to output a striking force to the fastener; the trigger assembly is configured to trigger a first switch and includes a first state for not triggering the first switch, and when the first switch is not triggered, the striker does not output the striking force; the brake assembly includes a lock state for preventing the striker from moving along the striking direction; and in response to the trigger assembly switching to the first state, the brake assembly switches to the lock state.

Fastening tool

A nail gun includes a housing, a power output assembly, a cylinder, and a firing assembly. At least a part of the power output assembly is disposed in the housing. At least a part of the cylinder is disposed in the housing. The firing assembly includes a firing pin provided with a first drive teeth capable of being driven, the first drive teeth includes a locking tooth provided with a rotating shaft, the rotating shaft is provided with a roller wheel, and the roller wheel is rotatable about a rotating axis.

A power tool includes a housing, a prime mover disposed in the housing, a first cylinder formed with a first chamber, a first rotating member rotatable with respect to the first cylinder about a first axis under the driving of the prime mover, a first piston movable in a direction parallel to the first axis when the first rotating member rotates relative to the first cylinder. The first cylinder and the first rotating member are disposed within the housing. The first piston is disposed within the first chamber The first rotating member is formed with a first transmission structure to drive the first piston The first piston is formed with a second transmission structure capable of cooperating with the first transmission structure to rotate the first rotation member to drive the first piston.
