Abstract
A hammering tool with buffer design includes: a hammering member, a protrusion block section extending from a lower side of the hammering member, a right side of upper section of the protrusion block section being notched to form a first receiving space; a handle member having a grip section, a first plate section, a second plate section and a third plate section being disposed at an upper end of the grip section to define a receiving chamber for inserting the protrusion block section therein; a pivot member for pivotally connecting the protrusion block section of the hammering member with the handle member; and a buffer assembly including a first compression spring received in the first receiving space. A right end face of the protrusion block section of the hammering member is spaced from a left face of the first plate section by a predetermined buffering distance.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
