[0006] Preferably, the glue inlet is connected to the glue barrel via a threaded connection structure.

[0007] Preferably, a plurality of reinforcing ribs are distributed below the outer wall of the nozzle body.

[0008] Preferably, the arc-shaped chamfer at the inner wall of the cap-shaped structure allows the sealant to overflow evenly.

[0009] Preferably, the threads at the inner wall of the threaded sleeve frame are connected to the threads of the outer wall of the threaded barrel.

[0010] Preferably, the rotation of the threaded sleeve frame causes the threaded barrel to move, and the movement of the threaded barrel causes the limit block to move at an internal position of the slide groove.

[0011] Preferably, the movement of the threaded barrel causes the elastic rod to contact the arc-shaped protruding block B, and the arc-shaped protruding block B causes the elastic rod to be displaced.

[0012] Preferably, the displacement of the elastic rod causes the arc-shaped protrusion A to squeeze the rubber inner bag.

[0013] Compared with the prior art, the utility model provides a glue nozzle for sealing and gluing aircraft fasteners, which has the following beneficial effects:

[0014] In this device, glue flows in the rubber inner capsule inside the main body of the glue nozzle. When adjusting, the threaded sleeve frame can be rotated to move the threaded barrel. At the same time, the limit block is clamped in the slide groove and moves. The movement of the threaded barrel will cause the elastic rod to contact the arc-shaped protruding block B, causing the elastic rod to be displaced. The movement of the elastic rod causes the arc-shaped protruding block A to contact the rubber inner capsule. The greater the deformation of the elastic rod, the greater the squeezing of the rubber inner capsule, thereby reducing the flow of glue, which can ensure uniform gluing effect and thus improve product quality.

[0015] The length of the slide groove is limited, which can ensure that the threaded barrel will not move to separate from the threaded sleeve frame when the threaded sleeve frame rotates, and the slide groove can limit the moving distance of the threaded barrel to prevent damage to the elastic rod due to excessive moving distance.
