Title:
NAIL-SHOOTING DRIVING MECHANISM AND NAIL GUN
Document Type and Number:
WIPO Patent Application WO/2024/055535
Kind Code:
A1
Abstract:
A nail-shooting driving mechanism (40) and a nail gun (10). The nail-shooting driving mechanism comprises a piston (41), at least one power supply spring (42), a pushing member (43) and a driving electric motor (44), wherein the piston (41) has abutting ends that match pushing ends; the abutting ends comprise a first abutting end (411) extending from the piston (41) in the nail shooting direction of the nail gun (10), and a second abutting end (412) extending from the piston (41) towards the pushing member (43); and the pushing ends comprise a first pushing end (431), which matches the first abutting end (411), and a second pushing end (432), which matches the second abutting end (412), the outer diameter of the second pushing end being less than that of the first pushing end (431). Since the pushing member (43) is provided, directly cooperates with the piston (41) and is configured to push the piston (41) to move towards the power supply spring (42), the power supply spring (42) is compressed to store energy; and the pushing member (43) is not in direct contact with a firing pin (49), thereby preventing the movement of the piston (41) from being affected due to the contact with the firing pin (49), such that the entire energy storage process is smoother and more stable.
