A
copper removal
brush for a
gun barrel is formed by a
brush head, a
pipe brush and a brush
handle which are connected into a whole; an air inlet plug and one end of a screw plug are connected with two ends of the brush
handle respectively; the screw plug is provided with a liquid shifting hole and a liquid leakage hole which are communicated with each other; the brush head and the other end of the screw plug are connected with two ends of the
pipe brush respectively; a screw plug end of the
pipe brush is connected with a liquid
coating plate which is closely attached to the liquid leakage hole formed in the screw plug. The
diameter of the liquid shifting hole formed at the edge of the screw plug is small, the
copper removal brush rotates to enable a
solvent to be squeezed to the pipe wall under the action of the
centrifugal force, easily enter the screw plug from the liquid shifting hole and flow onto
wool felt through the needle point size of liquid leakage hole formed in the screw plug to be used, the liquid quantity is not large, and accordingly the flowing of liquid droplets is avoided, the use of a cleaning solution is reduced, and the
pollution to the environment is not produced. The brush head is smooth and accordingly collisions and bruises of the inner wall of a gun bore are not produced,
metal combustion materials and
dirt of every position of the gun bore are removed through the spiral pipe brush, the sealing effect is achieved due to a sealing ring and the
wool felt which are arranged at the brush
handle end, and a
copper removal agent can be uniformly brushed at every position of the inner wall of the gun bore without leakage due to the
wool felt and accordingly the inner wall of the gun bore is fully utilized and is not damaged.
