[0002] As a common fastener, a clamping nail is widely used in furniture manufacturing, wood assembly, decoration and packaging industries. The clamping nail usually has a U-shaped structure, and the two legs are parallel and have a fixed spacing. In the use process, the clamping nail needs to enter a nail inlet channel through a nail inlet of a nail gun, and then be shot into a workpiece by a firing mechanism. Since the clamping nail needs to keep the two legs parallel and enter the channel at the same time, the height and position accuracy of the nail inlet are required to be high.

[0003] The nail gun in the prior art usually has a nail inlet with a fixed height at the front end of the gun body, which is suitable for a certain specification of clamping nail. When different height or different type of clamping nail is replaced, if the nail inlet is too high, the clamping nail is prone to posture deviation in the process of entering the channel, the two legs cannot keep parallel and bear stress, and finally the clamping nail is stuck or deviated, which affects the shooting effect.
