The technical scheme of the utility model is as follows: the variable-diameter cleaning brush for the gun barrel bore comprises a handle, wherein the right end of the handle is connected with a screw rod, a left T-shaped nut and a right T-shaped nut which are opposite in rotation direction are arranged outside the screw rod, the two T-shaped nuts are respectively connected with wedge-shaped bodies with opposite directions, a variable-diameter brush body is arranged outside the wedge-shaped bodies, and a silica gel sleeve is arranged outside the brush body; the screw rod is connected with a cotton rope pressing plate, the outer circumference of the cotton rope pressing plate is connected with cotton ropes, and the cotton ropes are positioned outside the silica gel sleeve.
The brush body is equally divided into a plurality of monomers along the circumferential direction.
The elastic band is sleeved outside the brush body, and the silica gel sleeve is positioned outside the elastic band.
The cotton rope pressing plate is fixed on a hollow bolt, the bolt is sleeved outside the screw rod, and the outer surface of the cotton rope pressing plate is fixed with a plurality of cotton ropes through the cotton rope pressing ring.
A spring A is arranged between the left side of the left T-shaped nut and the handle; the right end of the screw rod is externally connected with a nut B, and a spring B is arranged between the right side of the screw rod and the nut B.
The left end of the handle is connected with the connector through a universal joint, and the left end of the connector is connected with the handle bar.
The left side of the left T-shaped nut is provided with a flat washer B, and the right side of the handle is provided with a flat washer A.
The utility model has the following beneficial effects: by adopting the scheme, the cleaning brush can control the diameter of the cleaning brush to be enlarged after entering the gun barrel, so that the cleaning material is extruded into the internal cavity shadow line of the gun barrel, the positive pressure on the inner wall of the gun barrel is increased, the cleaning effect is improved, and the cleaning of the internal cavity of the gun barrel is completed. The problem that the cleaning effect is poor because the cleaning brush enters the gun barrel and the cleaning effect is too small is avoided, and the problem that the cleaning brush cannot be introduced into the gun barrel due to the too large diameter is solved.

Description of the embodiments
The utility model is further described below with reference to the accompanying drawings:
the gun barrel bore reducing cleaning brush comprises a handle 4, wherein the left end of the handle 4 is connected with a connector 2 through a universal joint 3, and the left end of the connector 2 is connected with a handle bar 1, so that the universal joint 3 can enable the handle 4 to freely rotate in all directions when the handle bar 1 is held to clean a gun barrel. The right end of the handle 4 is connected with a screw rod 5, the outside of the screw rod 5 is respectively connected with a left T-shaped nut 22 and a right T-shaped nut 14, the left T-shaped nut and the right T-shaped nut are oppositely rotated, and the left T-shaped nut and the right T-shaped nut can oppositely move along the screw rod 5 or move in opposite directions. The two T-shaped nuts are respectively connected with the wedge-shaped bodies 9 with opposite directions, the brush bodies 10 with variable diameters are arranged outside the wedge-shaped bodies 9, when the two T-shaped nuts drive the wedge-shaped bodies 9 to move inwards, the brush bodies 10 can be expanded outwards, the diameter becomes larger, and when the two T-shaped nuts drive the wedge-shaped bodies 9 to move inwards and outwards, the brush bodies 10 retract inwards, and the diameter becomes smaller.
The end part of the screw rod 5 is provided with a flat washer A6, the left side of the left T-shaped nut 22 is provided with a flat washer B8, a spring A7 is arranged between the flat washer A6 and the flat washer B8, and two ends of the spring A7 are respectively welded on the flat washer A6 and the flat washer B8. Under the action of the elastic force of the spring A7, the flat washer A6 and the flat washer B8 respectively rotate and rub with the end face of the handle 4 and the end face of the left T-shaped nut 22, and by adjusting the elastic force of the spring and the roughness of the surface of the flat washer, the friction force can be increased, the self-locking is realized, and the loose diameter of the brush body 10 is prevented from being reduced in the push-pull process. The right end of the screw rod 5 is externally connected with a nut B21, and a spring B20 is arranged between the right side of the bolt 17 and the nut B21.
The brush body 10 is equally divided into a plurality of monomers along the circumferential direction, the optimal number of the monomers is 6, and the 6 monomers retract to form a ring body. The elastic band 11 is sleeved outside the brush body 10, and the elastic band 11 is adhered to the brush body 10 by glue, so that the diameters of a plurality of brush body monomers are ensured to be uniform. The outside of the elastic band 11 is provided with a silica gel sleeve 12, and the cleaning material is extruded by the high elasticity of silica gel, so that the cleaning material is uniformly stressed and fills the female line groove of the inner bore of the gun barrel, and the cleaning of the inner wall of the gun barrel is completed. The lead screw 5 is connected with a cotton rope pressing plate 18, the outer circumference of the cotton rope pressing plate 18 is connected with a cotton rope 13, and the cotton rope 13 is positioned outside the silica gel sleeve 12. When the brush body 10 expands outwards, the silica gel sleeve 12 extrudes the cotton rope 13 outwards, so that the cotton rope 13 fills the female line groove of the inner bore of the gun barrel, and the cleaning of the inner wall of the gun barrel is completed.
The cotton rope pressing plate 18 is fixed on the hollow bolt 17, the bolt 17 is sleeved outside the screw rod 5, and the cotton rope pressing plate can move left and right along the screw rod 5.
