A nail gun of the present invention includes an adjusting portion which has elasticity. The elasticity of the adjusting portion is able to offset a thrust force of a nail pusher pushed by a magazine, so that a nail slot receives a nail only. The nail gun ensures not to shoot two sticks of nails simultaneously. The nail squeezes one side of the adjusting portion in a firing process so that the nail gun can provide sufficient space. Thereby when the nail is thicker, it can be shot by the nail gun. The present invention need not adjust by hand anymore for shooting different thickness of nails. The nail gun can not shoot two sticks of nails simultaneously.

A nailing unit and a nail gun including the nailing unit includes a guide plate, a nail box to mount staple nails or straight nails, and a nail feeding plate slidably connected to a nail compartment; the nail box is fixedly connected to a guide plate at one end, and forms a nail outlet at the position of connection; the nail feeding plate can push staple nails or straight nails to the nail outlet; bumps are fixedly provided inboard of the guide plate lengthwise; two bumps and the nail outlet form a nail discharge groove for matching the nailing plate, and suit to different specifications of straight nails or staple nails.

A nailing unit and a nail gun comprising said nailing unit comprises a guide plate, a nail box to mount U nails or T nails, and a nail feeding plate slidably connected to said nail compartment; said nail box is fixedly connected to said guide plate at one end, and forms a nail outlet at the position of connection; said nail feeding plate can push U nails or T nails to the nail outlet; bumps are fixedly provided inboard of said guide plate lengthwise; said bumps and the nail outlet form a nail discharge groove for matching the nailing plate, and suit to different specifications of T nails or U nails.

The invention provides a pneumatic nail gun, comprising a gun body, a nail box, a fork and a nail forming device. The gun body comprises a sliding groove, a nail outlet adjacent to the sliding groove and a push block. The nail box and the fork are fixed on the gun body. The nail box is configured to place a plurality of strip nails to be sequentially exposed from the nail outlet. The formed fork comprises two forming surfaces with unequal heights, and the two forming surfaces are adjacent to the nail outlet. The nail forming device comprises two jaw arms, two control arms and a push seat, and the push block drives the two control arms to drive the two jaw arms to rotate and close the two forming jaws, and to drive the push seat to slide on the sliding groove.

A magazine assembly and a stapler including the same are provided. The magazine assembly includes a base and a rail assembly. The base has a first end portion and a second end portion. A direction from the second end portion toward the first end portion is defined as a first direction. The rail assembly is disposed on the base and adapted for a staple unit to movably abut thereagainst along the first direction. The rail assembly includes a first rail and a second rail which are separate. A first side wall of the first rail has at least one guiding portion extending in the first direction. Each guiding portion is adapted for a head of a T-shaped staple to slidably engage therewith along the first direction. The second rail is adapted for a U-shaped staple to abut thereagainst.
