Staple gun automatically applicable to staples of multiple sorts

摘要

A staple gun (10) includes: a casing (20) having a front blocking surface (232); a magazine (40) disposed in the casing (20); and a staple delivery element (50) and a resilient element (60) disposed at the magazine (40). The magazine (40) includes at least a staple cutting portion (461) each having a top surface (462), a front end surface (464), and a guiding surface (466) connected between the top surface (462) and the front end surface (464). The front end surface (464) and the guiding surface (466) face the front blocking surface (232). A clearance (48) for passing staples (80) is disposed between the front end surface (464) and the front blocking surface (232). The staple delivery element (50) pushes staples (80) in the magazine (40) in a staple delivering direction (D2). The resilient element (60) enables staples (80) to push the front end surface (464) and the guiding surface (466) of the staple cutting portion (461) of the magazine (40), such that the magazine (40) moves relative to the casing (20) in a clearance adjustment direction (D3) opposite to the staple delivering direction (D2).
