The top of the double-ended stud 12 shown is the hexagonal top 15 matched with the stud adjustment cap 3-1; during use, the stud adjustment cap 3-1 is broken off and removed, and installed into the hexagonal On the top 15, the rotation adjustment of the double-ended stud 12 can be effectively realized.

As shown in Figure 6 and Figure 7, respectively provide the structural representation of the glue applicator of the present invention when gluing to larger and smaller diameter sizes, the use steps of the screw thread glue applicator of the present invention are as follows:

The assembly method during production is:

At first the bottle cap 2 and the glue bottle 1 that are equipped with the glue nozzle 3 to be used are installed, and the bottle cap 2 and the glue bottle 1 are completely closed at this moment, even if the screw thread glue applicator of the present invention is not installed, the glue nozzle 3 and the glue bottle 1 to be used are completely closed. The cooperation of the bottle cap 2 can also be used alone; then the fixed part 5 of the glue applicator is packed into the inner annular cavity 2-2 of the bottle cap 2, and a glue applicator preinstalled on the glue bottle 1 is formed.

The method of gluing operation is:

(1) Take out the rubber nozzle 3 to be used; first pull out the fixing part 5 from the annular cavity 2-2, so that the glue applicator is separated from the bottle cap 2; unscrew the rubber nozzle 3 to be used and then fix it again Part 5 is loaded into, and the glue solution in the glue bottle 1 just passes through central through-hole 2-3, glue solution cavity 16 and lumen 7 successively and communicated with glue outlet 10 like this.

(2) Adjust the upper arc part 8 and the lower arc part 9 to a suitable opening; after confirming that the fixed part 5 and the bottle cap 2 are assembled, break off the stud adjustment cap 3-1 at the top of the glue nozzle 3 to be used (the stud adjustment cap 3-1 is weakly connected with the rubber nozzle 3 to be used), install it on the hexagonal top 15 of the stud 12, and turn the stud 12 to adjust the gap between the upper and lower rubber hoses 6 distance until the opening between the upper arc portion 8 and the lower arc portion 9 reaches a suitable bolt diameter. Since the thread directions of the upper and lower threaded holes 11 and the thread directions of the two ends of the double-ended stud are opposite, the double-ended stud 12 can drive the two rubber hoses to open or tighten at the same time during the rotation.

(3) Apply glue to the bolts; after adjusting the caliber, when holding the glue bottle 1 with one hand, the mouth of the bottle hangs down normally, at this time, the opening formed by the upper arc part 8 and the lower arc part 9 will also face downward; pick up the bolt to be glued Insert 17 into the opening between the upper arc 8 and the lower arc 9 to an appropriate length, squeeze the rubber bottle 1 normally, and the glue will pass through the glue outlets on the upper arc 8 and the lower arc 9 10 flows out and is coated on the screw thread of bolt 17, pulls out bolt 17, and gluing process promptly finishes. In this way, the glue application length on the bolt 17 is determined by the insertion length, and the glue application width is determined by the bonding width of the glue outlet 10 and the bolt 17 . If the diameter of the bolt is large, it can be repainted again by turning the angle.

Since the upper arc portion 8 and the lower arc portion 9 and their glue outlet 10 are always kept perpendicular to the lumen 7 in the rubber hose 6, this makes the glue outlet 10 with a smaller diameter no longer in the same horizontal plane when applying glue Inside, the middle part of the glue outlet 10 should be lower than the height of both ends; the middle part of the glue outlet 10 has priority to discharge glue due to its lower position, so that when the small diameter bolt 17 is applied, the whole glue outlet 10 will not always come out. Glue, resulting in waste of glue; this actually makes the width of the glue outlet of the glue outlet have a certain degree of self-adaptability. Of course, if the actual working conditions do not require the use of a glue applicator (such as the case of internal thread), then reverse the standby glue nozzle 3 with the stud adjustment cap 3-1 removed and screw it into the central through hole 2- of the bottle cap 2 3, this becomes a conventional glue bottle with a glue nozzle.
