Abstract: A nail gun includes a housing, a safety device, a gun barrel, a supporting part, a block, a nosepiece, a linkage, a contacting part, a protrusion, a front linking part, a rear linking part and an arm. The safety device is arranged on the housing. The gun barrel is located at the front end of the housing. The supporting part is arranged inside the housing and has an elastic element. The block is disposed on the gun barrel. The nosepiece and the linkage are slidably arranged on the gun barrel. The contacting part is located at the front end of the nosepiece. The protrusion is applied to against the block. The front linking part is located at the rear end of the nosepiece. The rear linking part detachably connects the front linking part. The arm is located at the rear end of the linkage and against the elastic element.

Abstract: The nail presser lid structure for a nailer includes a coupling end and a swinging end. The swinging end is provided with a flexible presser, formed of a presser portion and a spring. The presser portion protrudes from the swinging end to press on the closing side of the removable cover. An inclined guide plane is placed outside of the presser portion. When the removable cover presses the inclined guide plane, the presser portion is forced to return and press the spring to accumulate elastic restoring force. When the closing side of the removable cover overpasses the inclined guide plane, the presser portion will recover again and press the positioning portion of the closing side, such that the nail presser lid and removable cover of the nail box are closed flexibly, offering greater operational friendliness and practicability.

Abstract: A nail magazine for a nailer comprises a base, a cover pivotally and elastically connected to the base, and a receiving disc. Once the cover is pulled outward, it can be pushed a certain angle away from the base automatically. On a side of the cover are formed an ear and a rotary shaft. The receiving disc is correspondingly provided with a rotary member. By disengaging the cover from the base and moving it to an angle and then keeping moving it, the receiving disc can be moved out of the base completely, for easy nail loading. Therefore, the operation is simple, quick and can be done with one hand.
