At this time, under the elastic force of the limit spring 14, the upper limit portion 15 of the limit block 13 forms abutment with the gun nozzle positioning slide plate 17, thereby preventing the gun nozzle 3 from moving and entering the anti-air shooting state; when there are rows of nails in the nail clamp 4, the coil spring 8 in the head device 7 maintains the propulsion force on the row of nails 9, and the propulsion force received by the row of nails simultaneously pushes the side of the positioning portion 16 of the limit block 13 against the limit block 13, and the limit block 13 compresses and moves the limit spring 14, and the positioning portion 16 thereon corresponds to the positioning groove 18 on the positioning slide plate 17, so that the gun nozzle 3 can move through the positioning groove 18 and enter the nailing use state.

[0026] Furthermore, a positioning groove 19 is provided on the gun nozzle 3, and a replacement device 1-2 is provided between the nail head 1 and the cover plate 2, and the replacement device 1-2 includes a positioning spring 20 and a limit pin 21; the positioning spring 20 and the limit pin 21 in the replacement device 1-2 are positioned and installed through the nail head 1 and the nail head cover plate 2, and the elastic force of the positioning spring 20 keeps acting on the limit pin 21, so that its end is positioned against the positioning groove 19, and the end shape of the limit pin 21 matches the positioning groove 19, and the gun nozzle 3 forms a sliding connection with the nail head 1 through the matching of the limit pin 21 and the positioning groove 19, and the gun nozzle 3 is subjected to force to press the limit pin 21 and compress the positioning spring 20, so that the replacement device 1-2 releases the positioning connection effect on the gun nozzle 3, and the gun nozzle can be conveniently replaced and used through the replacement device, and other gun nozzles to be replaced are also equipped with a structural design corresponding to the replacement device and the reset device.

[0027] Furthermore, a reset device 1-3 is installed in the cover plate 2, and the reset device 1-3 includes a reset member 22 and a reset spring 23; a bracket 24 is provided on the gun nozzle 3, which abuts against the reset member 22, and the reset spring 23 has elastic force on the reset member 22, so that the reset member 22 and the bracket 24 form abutment; thereby acting on the gun nozzle 3, so that the end of the positioning groove 19 on the gun nozzle 3 and the limit pin 21 remain positioned and abutted, and the reset device 1-3 can not only cooperate with the replacement device to position and connect the gun nozzle 3, but also ensure the reciprocating movement and reset of the gun nozzle during use.

[0028] Furthermore, the mounting hole 12 includes a rod hole portion 25, a spring hole portion 26, and a limit hole portion 27, and a positioning rod 28 is provided on the limit block 13; during installation, the positioning rod 28 on the limit block 13 is penetrated through the rod hole portion 25 and the spring hole portion 26, and the positioning rod 28 can extend out of the rod hole portion 25, thereby determining whether the anti-air strike device 1-1 is in an anti-air strike state; the limit spring 14 is sleeved on the positioning rod 28 and maintains an elastic force on the limit block 13, so that the limit block 13 passes through the gun nozzle positioning slot 10, so that its positioning portion 16 remains in the positioning hole 11.

[0029] Preferably, the limiting portion 15 and the positioning portion 16 of the limiting block 13 are quadrilateral, and the shapes of the limiting hole 27 and the positioning hole 11 match the shape design of the limiting block; the shape design of the limiting block 13 can position it during its movement, thereby preventing movement deviation.

[0030] Furthermore, both sides of the muzzle positioning groove 10 are provided with limit grooves 29 corresponding to the mounting hole 12. In the anti-air strike state, the limit portion 15 of the limit block 13 can be partially located between the two limit grooves 29, so that the limit block 13 can be better positioned downward in the anti-air strike state.

[0031] Furthermore, a firing pin side sliding slope 30 is provided at the upper end of the positioning portion 16 of the limit block 13 corresponding to the nail groove 6.
