Description

Technical Field

[0001] The utility model relates to the technical field of spray guns, in particular to an extension rod device for a spray gun. Background Art

[0002] A spray gun is a professional tool used to spray liquid coatings, paints, varnishes, preservatives, and other substances. It uses compressed air or other power sources to atomize the liquid into fine particles and spray them evenly onto the surface being coated. A spray gun extension is an auxiliary tool used to extend the effective working range of the spray gun. Connecting between the spray gun and the compressed air line, it increases the overall length of the spray gun, allowing the operator to spray while maintaining an appropriate distance. This is particularly useful when spraying in hard-to-reach locations, such as high up, in confined spaces, or when operating from a distance from the spray gun.

[0003] For example, Chinese patent publication number CN213255296U discloses an extension rod device for a spray gun, comprising a spray gun body, a first extension rod being threadedly connected to one end of the spray gun body, a rotating mechanism being fixed to the end of the first extension rod away from the spray gun body, the rotating mechanism comprising a handle, a handle being fixed to the end of the first extension rod away from the spray gun body, an end of the handle away from the first extension rod being rotatably connected to a second extension rod via a bearing, the first extension rod and the second extension rod both being hollow, the second extension rod being rotatably connected to the first extension rod, an adjustment mechanism being fixed to the end of the second extension rod away from the handle, and a spray head being fixed to one end of the adjustment mechanism;

[0005] However, this solution adjusts the direction of the nozzle by setting a rotating block. During use, the direction of the nozzle cannot be adjusted, and only the pitch angle of the nozzle can be adjusted, which is inconvenient to use.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and an extension rod device for a spray gun is provided, in order to achieve the purpose of having more practical value. Utility Model Content
