Abstract
An energy storage mechanism and a nail gun having the same. The nail gun includes a driving mechanism having a piston, a nail striking member co-movably connected to the piston, and a driving member being operably alternatively engaged and disengaged with the nail striking member. The energy storage mechanism includes a cylinder and at least one spring disposed in the cylinder such that an engagement of the driving member with the nail striking member causes the piston to move backward in the cylinder to push the at least one spring into a contract state so as to store energy therein, and an disengagement of the driving member with the nail striking member causes the least one spring to release the stored energy therein to push the piston to move frontward in the cylinder so that the nail striking member is co-moved therewith to strike a nail out of a muzzle.
