Patent ID: 8453902

Claim:
A nail gun comprising: a gun barrel located at a front end of a housing and extending in an axial direction; a supporting part arranged inside the housing; an elastic element disposed forwardly of and in abutment with the supporting part in the housing; a block disposed on the gun barrel; a nosepiece slidably and detachably arranged on the gun barrel in the axial direction and terminating at opposite front and rear ends in the axial direction, including a contacting part which is located at the front end of the nosepiece, a protrusion which is disposed offset from an axis of the gun barrel and adjacent to the rear end of the nosepiece, which is disposed behind the block relative to the front end, and which is slidable relative to the block in the axial direction between operating and non-operating positions, where the protrusion is disengaged from and engaged with the block, respectively, and a rearward linking part which is located at the rear end of the nosepiece; and a linkage arranged on the gun barrel and disposed to be movable with the nosepiece in the axial direction, including a forward linking part configured to permit the rearward linking part to be detachably engaged therein and rotatable thereto about the axis and liftable therefrom, and an arm disposed to extend from an end of the forward linking part rearward to terminate at an abutment end which is disposed forwardly of and biased by the elastic element to move the protrusion toward the non-operating position, such that as a result of the nosepiece being manually pushed against the biasing force of the elastic element, the protrusion is disengaged from the block so as to permit the protrusion to be turned about the axis thereby enabling the detachment of the rearward linking part from the forward linking part.
