Sealing grease daubing gun

The utility model discloses a sealing-grease smearing gun used in petroleum and natural gas industries which is applicable for uniform smearing of the sealing grease for pipes and poles used in gas and water well construction applications, and which can also be used in applications of pressure test constructions for ground vitas, drill pipes, down-hole operations, well drilling and oil construction system. The utility model can control the uniform moving of sealing grease by a hand-grasping ejector pin mechanism. A smearing mechanism transports sealing grease to the place between the smearing mechanism and the vitta internal thread. The added smearing block can help to form a uniform layer of sealing grease on the vitta internal thread. Some appropriate smearing mechanisms are designed to fit the vitta with different diameters. The utility model is easy and reliable for operation, therefore, production cost and labor working intensity can be reduced.
