The invention discloses a rotating wheel handgun, which relates to the field of light weapon. The bulldog of the prior art has the disadvantages of complicated structure, big volume and slow loading speed, and the rotating wheel just can be put out from the lift side of the gun body and the gap between the rotating wheel and the gun barrel can not be sealed so that the aiming tool is inconvenient to aim. An upper machine box of the invention is provided with an automatic shell throwing mechanism inside which is linked with the trigger; a screw hole of the gun body is screwed with a chest closing device inside; the cross sections of the front and the rear posts symmetrically and mutually incline to form a certain angle; the points of the two posts are arranged on the central line of the gun barrel. A spring bullet clip is connected with 6 bullet hoops at the elastic bent bullet clip with two separable ends so as to use the common handgun bullet without bottom edge. The invention has the advantages of simple structure, compact distribution, automatic shell throwing, rapid bullet loading, sealing the bullet chest, unique aiming device and completely symmetric structure. The rotating wheel handgun of the invention can be conveniently operated by the left hand and the right hand.

The invention discloses a gutter inlet garbage filtering and circulating system convenient to replace, and relates to the field of urban road drainage facilities.
