The gun barrel grip of a high-pressure cleaning machine is a commonly used accessory for high-pressure cleaning machines. It is usually installed on the gun barrel and is also called the gun barrel side handle. When the cleaning machine is working under high pressure, it is necessary to hold the gun barrel with greater force to keep the gun barrel stable, so that the high-pressure water flow will be sprayed on the designated surface of the object as required by the operator. The gun barrel grip can help the operator control the gun barrel more conveniently and stabilize the gun barrel. The gun barrel grip is usually made of soft plastic with patterns on the surface, which is comfortable to hold and will not slip. The inner core is made of metal, generally carbon steel, with a bolt on the head, which is screwed on the ring of the gun barrel. Tighten the bolt and the head against the gun barrel to fix the grip tightly on the gun barrel. When not in use, the bolt can be loosened and the grip can be removed for easy carrying and packaging.
