a light source assembly comprising at least one lighting subject body; and a lens assembly, located on the exit path of said light source assembly, comprising at least one lens, wherein at least one of said lighting subject bodies is mounted on said mounting main housing along an optical axis of said light source assembly in a movable manner such that said at least one of said lighting subject bodies moves relative to said lens assembly; wherein said light source assembly comprises a driving inner cone, and a driving outer cone covered outside said driving inner cone, said lighting subject body is installed on said driving inner cone, and said driving inner cone is mounted on said driving outer cone along the optical axis of said light source assembly in a movable manner; wherein said driving inner cone has an external thread located on a surface thereof, and said driving outer cone has an internal thread located on an inner wall thereof to enable said driving inner cone to move within said driving outer cone, so as to carry said lighting subject body moving relative to said lens assembly. ### Claim 2 (depends on 1) The focus adjustable pistol type spotlight, as recited in any one claim 1, wherein said light source assembly further comprises a guiding member mounted on said driving inner cone for guiding said driving inner cone to move along the optical axis set by said light source assembly. ### Claim 3 (depends on 2) The focus adjustable pistol type spotlight, as recited in claim 2, wherein said light source assembly further comprises a guiding inner cone covered outside said driving inner cone, said driving inner cone comprises an inner cone body and at least one fixed protrusion formed on the outer surface of said inner cone body; said guiding inner cone has at least one guiding groove corresponding to said fixed protrusion, and said extension direction of at least part of said guiding groove is consistent with the optical axis set by said light source assembly, and said fixed protrusion can be arranged in said guiding groove in a slidable manner. ### Claim 4 (depends on 3) The focus adjustable pistol type spotlight, as recited in claim 3, wherein said external thread of said driving inner cone is formed on an outer surface of said fixed protrusion. ### Claim 5 (depends on 4) The focus adjustable pistol type spotlight, as recited in claim 4, wherein said light source assembly further comprises an operating sleeve, a light source mounting body and an optical bowl, said operating sleeve is covered outside said driving outer cone, said light source mounting body is installed in said driving inner cone, said lighting subject body is installed in said light source mounting body and extended out of said driving inner cone; said optical bowl is covered outside the periphery of said lighting subject body. ### Claim 6 (depends on 3) The focus adjustable pistol type spotlight, as recited in claim 3, wherein said driving inner cone comprises a plurality of fixed protrusions arranged with respect to each other in a spaced manner, and the plurality of said guiding inner cone have the plurality of said guiding groove corresponding to the plurality of fixed protrusion. ### Claim 7 (depends on 1) The focus adjustable pistol type spotlight, as recited in claim 1, wherein said driving outer cone is mounted on said mounting main housing in a rotatable manner along the optical axis of said light source assembly, and said driving outer cone is immovable in the direction of the optical axis of said light source assembly so that during the process of being rotated of said driving outer cone, said driving inner cone is moved along the optical axis of said light source assembly in said driving outer cone and drives said lighting subject body to move relative to said lens assembly. ### Claim 8 A focus adjustable pistol type spotlight, comprising: a mounting main housing having a pistol shaped structure and at least one receiving cavity located therein; a light source assembly comprising at least one lighting subject body; and a lens assembly, located on the exit path of said light source assembly, comprising at least one lens, wherein at least one of said lighting subject bodies is mounted on said mounting main housing along an optical axis of said light source assembly in a movable manner such that said at least one of said lighting subject bodies moves relative to said lens assembly; wherein said light source assembly comprises a driving inner cone, and a driving outer cone covered outside said driving inner cone, said lighting subject body is installed on said driving inner cone, and said driving inner cone is mounted on said driving outer cone along the optical axis of said light source assembly in a movable manner wherein said light source assembly further comprises a guiding member mounted on said driving inner cone for guiding said driving inner cone to move along the optical axis set by said light source assembly; wherein said light source assembly further comprises a guiding inner cone covered outside said driving inner cone, said driving inner cone comprises an inner cone body and at least one fixed protrusion formed on the outer surface of said inner cone body; said guiding inner cone has at least one guiding groove corresponding to said fixed protrusion, and said extension direction of at least part of said guiding groove is consistent with the optical axis set by said light source assembly, and said fixed protrusion can be arranged in said guiding groove in a slidable manner. ### Claim 9 (depends on 8) The focus adjustable pistol type spotlight, as recited in claim 8, wherein said driving inner cone comprises a plurality of fixed protrusions arranged with respect to each other in a spaced manner, and the plurality of said guiding inner cone have the plurality of said guiding groove corresponding to the plurality of fixed protrusion. ### Claim 10 (depends on 8) The focus adjustable pistol type spotlight, as recited in claim 8, wherein said external thread of said driving inner cone is formed on an outer surface of said fixed protrusion. ### Claim 11 (depends on 8) The focus adjustable pistol type spotlight, as recited in claim 8, wherein said light source assembly further comprises an operating sleeve, a light source mounting body and an optical bowl, said operating sleeve is covered outside said driving outer cone, said light source mounting body is installed in said driving inner cone, said lighting subject body is installed in said light source mounting body and extended out of said driving inner cone;
