Title:
FASTENER STRIKING TOOL
Document Type and Number:
WIPO Patent Application WO/2023/103570
Kind Code:
A1
Abstract:
Provided is a fastener striking tool, comprising: a housing (10), in which a compression chamber (9) for storing air and a cylinder body (8) with a built-in piston (7) are installed and a holder (4) is fixed; the holder (4), for supporting a drive wheel (5) driven by a motor and for installing a nailing seat (3) provided with a gun nozzle (1) at the front end to form a nailing channel (1-1) extending from the cylinder body (8) to the gun nozzle (1); a striker (6) which has a first end and a second end and transmissively meshes with the drive wheel (5), the first end being connected to the piston (7), the second end extending in the nailing channel (1-1) in a direction towards the gun nozzle (1) and reciprocating between a compression limit position and a nailing limit position; and a partition structure located near the compression limit position of the second end of the striker (6) and used for sealing the side gap between the striker (6) and the nailing channel (1-1). Since the partition structure blocks the pathway from which chippings and broken nails produced in the nailing process would enter the nail gun, parts damage and jamming faults caused by the entry of foreign matter such as chippings and broken nails can be avoided.
