| 摘要 |
The present invention relates to a device for washing a gun barrel which includes a longitudinal shaft center member including the front end and the rear end; a tubular woven sheath enclosing the center member; and a radial protrusion unit formed with a polymer arranged in the lower part of the tubular woven sheath around the center member. The radial protrusion unit is a thermoplastic matter in which the sheath is over-molded and radially extended from the inner diameter of the gun barrel. The center member includes fitting for being attached to a T-shaped handle or various auxiliary tools. A thread pattern of the protrusion unit formed in order for the sheath to be pressed to face a gun barrel rifling land is provided to the surface of the polymer. The sheath is woven with a natural fiber such as mainly cotton. The sheath is made by emitting light and grinding and weaving a heat-resisting thread. A sponge material can be arranged between the sheath and the center member. |
