More preferably, one end of the limiting strip 3 is hingedly connected with the gun nozzle body 21. When the limiting strip moves upward, the guide block moves upward in the avoiding hole, and the avoiding hole guides the movement of the guide block, thereby guiding the movement of the limiting strip. The guide block and the avoiding hole cooperate to further move the limiting strip in the predetermined direction without deviation, thereby ensuring smooth nailing. Meanwhile, the avoiding hole is arranged to enable the gas in the limiting slot to quickly enter and exit the limiting slot, so that the limiting strip can move freely in the limiting slot.

[0051] Further, as shown in the figure, Figure 6As shown, the muzzle assembly further comprises a reset elastic member 4; the muzzle body 21 is provided with a reset slot 23 communicated with the limiting slot 22, the reset elastic member 4 is arranged in the reset slot 23 and abuts against the muzzle body 21 and the limiting strip 3 respectively, so that the limiting strip 3 is arranged in the nail discharging slot 11. The reset elastic member 4 is a spring. The reset elastic member is arranged above the limiting strip and abuts against the limiting strip and the muzzle body respectively, so that the reset elastic member is generated to the limiting strip, the limiting strip always has a downward moving trend and is always arranged in the nail discharging slot. In the process of driving the U-shaped nail, the limiting strip always presses the nail to ensure that the nail moves stably and does not deviate, so that the driving is carried out smoothly and the nail is not stuck. In the process of driving the I-shaped nail, the limiting strip is always arranged on one side of the nail to guide the movement of the nail, so that the nail does not deviate and the driving is carried out smoothly and the nail is not stuck. Meanwhile, the limiting strip is moved upward under the action of the hammer, and the limiting strip is reset under the action of the reset elastic member after the hammer exits the nail discharging slot, so that the driving is carried out smoothly next time. Therefore, the reset elastic member has the function of automatically resetting the limiting strip.
