The multistage muzzle chamber cleaning apparatus according to the present invention includes: a rotating member which has a power supply unit formed therein and a motor which is rotated by receiving the power supplied by the power supply unit; a rotating body which is rotated in conjunction with the motor; a cleaning member which is configured to have an oblique cleaning unit which is obliquely coupled to the outer circumferential front portion of the rotating body and a parallel cleaning unit, both ends of which are coupled in parallel to the outer circumferential rear portion of the rotating body; and a handle member which is formed in the rear portion of the rotating member such that the length thereof can be adjusted telescopically. According to the present invention, the chamber cleaning device is transported within a narrow space such that the inside of the chamber can be cleaned with improved convenience. Also, durability can be increased since an oblique portion and a parallel portion in the chamber are cleaned well. Further, a cleaning solution can be sprayed without using any additional members. In addition, brushes can be quickly interchanged to facilitate user access.

An apparatus for cleaning a gun barrel having striations formed on an inner surface of the gun barrel includes a cleaning means that is in contact with the inner surface of the gun barrel as being moved by a drive means installed inside a cylindrical main body. The cleaning means includes a main member having a circular plate on which a plurality of insertion holes is formed along its circumference; a rotating member formed inside the circular plate and having a motor and a rotating gear interlocking with the motor; and cleaning members formed to be inserted into the insertion holes, respectively, to clean the inner surface of the gun barrel and having lower sides interlocking with the rotating gear, respectively, to be rotated. The apparatus for cleaning a gun barrel is rotated at high speed with an appropriate pressure along the groove part of the gun barrel accurately, and thus a wide area can be cleaned in a short time. Even if the brusher is worn out, an appropriate pressure is maintained by the spring, and thus the amount of wear is compensated for. Since the brusher does not secede from the barrel, the accuracy is increased, and since the respective brushers are replaceable and it is not required to replace the whole cleaning member, the cost is saved.
