ABSTRACT:
A nail beating depth adjuster of a nail driver comprises a limiting cover, a first and a second spring, and a nut. The limiting cover is extended with a first seat and a second seat which are coaxial. A linkage passes through the holes in the first seat and second seat. A first spring encloses the linkage between the first seat and second seat. A nut encloses an outer thread of the linkage between the first seat and second seat. The first spring resists against the nut. The nut is formed with a plurality of buckling recesses which are spaced with an equal space. One of the end surfaces of first seat and second seat is formed with at least one tooth. Thereby, by the first spring pressing against the nut, the buckling recesses on the nut expands upon or engages with the tooth for adjusting and positioning.
