As shown in fig. 4, when the glue is required to be applied to the smaller glue outlet 3, for example, in the operations of caulking, leak repairing and the like, the appropriate position and angle are selected on the taper pipe section 23 to cut off the end part, so that the glue outlet 3 with appropriate size and inclination can be formed, after that, the glue can be applied without other operations, the discharged glue tends to be cylindrical, which is beneficial to the glue entering the gap and ensures the sufficient glue quantity.

As shown in fig. 5, when the glue outlet 3 needs to be glued with a larger size, for example, in the sealing and fixing of the internal corner line when building accessories such as doors and windows, glass and the like are installed, a proper position and angle are selected on the flat pipe section 21 to cut, so that the glue outlet 3 with a proper size and a duckbill shape can be formed, the convex rib 22 forms a V-shaped opening 31 on the upper side of the glue outlet 3 along with the cut flat pipe section 21, and then the glue can be glued without complex operations such as heating, extruding and the like of the glue nozzle, thereby being convenient, quick, time-saving and labor-saving, having lower operation requirements, and being only capable of being operated by ordinary personnel; the V-shaped opening 31 can increase the local glue amount of the discharged glue column in the glue spraying process, and accords with the shape characteristics of the internal corner; as shown in fig. 6, in actual use, the front end of the rib 22 may be further trimmed according to actual situations, and finally, the effect of saving the glue pressing step may be achieved, so as to improve the glue spraying efficiency.

Further, as shown in fig. 4 and 5, when the glue nozzle is sheared during the actual operation of the glue dispensing, the glue outlet 3 will generally have a certain inclination, and after the glue container, the glue nozzle and the glue gun are assembled, the glue outlet 3 and the glue gun should keep a specific relative direction to satisfy the operation habit or the working condition of the worker. The relative positions of the glue outlet 3 and the glue gun are fixed after the glue container is in sealing connection with the glue nozzle, and the glue container and the glue nozzle can be synchronously rotated to adjust the relative direction of the glue outlet 3 and the glue gun, so that the glue container is not convenient to drive the glue gun to rotate after being arranged on the glue gun, and the existing glue nozzle is not provided with a component convenient for force application, so that the existing glue nozzle is inconvenient to adjust the relative direction of the glue outlet 3 and the glue gun in the use process;

therefore, the rubber nozzle of the rubber gun for engineering construction is also improved as follows: referring to fig. 7, protruding fins 4 are arranged on the outer wall of the joint of the connector 1 and the rubber outlet pipe 2; based on the arrangement of the fins 4, the glue nozzle is convenient to screw by hands or tools, and when the connector 1 and the glue container are screwed to the tightest, the glue container synchronously rotates along with the glue nozzle, so that the relative direction of the glue outlet 3 and the glue gun can be adjusted to be expected; in addition, the fin 4 can also serve the purpose of improving the connection strength of the connector 1 and the rubber outlet pipe 2.
