Impact protection for nail driver

Abstract

A nail driver includes a securing slide rod, a knocking rod, a sleeve and an absorber. The securing slide rod has one end able to push on an inner trigger for actuating the nail driver by a trigger and the other end formed a receiving portion. The knocking rod has one end formed a bolt and the other end able to protrude outside the nail driver to press against a workpiece. The sleeve is connected between the securing slide rod and the knocking rod by screwing the bolt therein and being rotatably and movably received in the receiving portion. The absorber is mounted on an exterior surface of the sleeve to absorb impact passing from the knocking rod to the securing slide rod. As such, the securing slide rod and the knocking rod can be protected when the nail driver is accidentally dropped.

1 . A nail driver comprising: 
 a securing slide rod with one end able to reach an inner trigger for activation of the nail driver by a trigger and another end forming a receiving portion wherein the receiving portion includes an upper and a lower supporting plates;    a knocking rod with one end forming a bolt and another end protruding out of the nail driver to press against a workpiece for lifting the securing slide rod to push on the inner trigger;    a sleeve connected between the securing slide rod and the knocking rod by screwing the bolt therein from a distal end thereof and being rotatably and movably received in the receiving portion, wherein the sleeve includes a head to rest on the upper supporting plate and a cylindrical body to penetrate the upper and the lower supporting plates with the distal end protruding from the lower supporting plate; and    an absorber mounted on an exterior surface of the distal end of the sleeve to absorb impact passing from the knocking rod to the securing slide rod.
