1. A stroller comprising:
a support frame including
a pair of vertical bars, lengths which are vertically controllable in a telescopic manner, and provided to be spaced apart from each other,a one-side support and an other-side support, respectively disposed at one side and an other side, to include horizontal bars each having both ends connected to the pair of vertical bars to support the pair of vertical bars, andside supports and a bottom support configured to connect the one-side support and the other-side support to form a square frame shape having an upper side opened with the one-side support and the other-side support, and form side frames and a bottom frame,wherein the side supports and the bottom support enable the one-side support and the other-side support to be adjacent to or spaced apart from each other in a folding manner in conjunction with lifting or lowering of the vertical bars; extension rods respectively coupled to the vertical bars to be capable of vertically moving into or out of upper ends of the vertical bars; safety belts; an inner sheet formed in a shape corresponding to an internal space of the support frame to be accommodated in the internal space of the support frame, having one or both of one side and the other side coupled to the safety belts, and having coupling portions detachably coupled to the horizontal bars and the side supports at an upper end circumference thereof; detachable members detachably coupled to the extension rods; and a sun cover coupled to the detachable members, integrally detached from and attached to the extension rods according to detachment and attachment of the detachable members from and to the extension rods, and configured to cover an upper side portion of the support frame, wherein each of the vertical bars comprises a lifting bar configured to move into or out of an upper end of the vertical bar in a telescopic manner, having an upper end which has a cylindrical shape in which an upper side is opened, and having an inner circumferential surface which has second threads, and an extension rod controller configured to allow a respective one of the extension rods to vertically move in or out, or to be fixed and coupled to and restricted by the lifting bar, and the extension rod controller comprises a first extension rod controller or a second extension rod controller, wherein the first extension rod controller comprises
a first header having a first through hole configured to vertically pass therethrough; andan expansion-contraction portion having one or more cut portions configured to extend downward from the first header, having first threads capable of being coupled to the second threads on an outer circumferential surface thereof, and having a lower end portion cut toward an upper side thereof, andwherein the extension rod is restricted by the expansion-contraction portion being contracted toward an inside and being in tight contact with an outer circumferential surface of the extension rod when the extension rod vertically passes through the first header and the expansion-contraction portion and the first threads and the second threads are screw-coupled to each other, andfurther wherein the extension rod is capable of vertically moving when the first threads and the second threads are unscrewed from a screw-coupled state and the expansion-contraction portion expands, and wherein the second extension rod controller comprises:a controller body having third threads formed at an inner circumferential surface, having a second through hole formed at a center of an upper side surface, including a plurality of guide films extending downward a certain length along a cut portion of the second through hole to form a coupling space between the inner circumferential surface of the controller body of the second extension rod controller and the plurality of guide films, and including a cap in which gaps are formed between the plurality of guide films; anda coupling body including a second header which has an extension portion having fourth threads formed at an outer circumferential surface, enabling the fourth threads to be coupled to the third threads, contracting the guide films toward an inside thereof, and coupled to the coupling space, a neck portion connected to have a smaller diameter than the extension portion, and a pipe portion configured to extend from the neck portion, having fifth threads formed on outer circumferential surface, configured to be screw-coupled to the second threads of the lifting bar, and having a pipe shape, andwherein the extension rod is restricted by the inner circumferential surface of the extension portion contracting the guide films toward an inside thereof and the guide films and the outer circumferential surface of the extension rod being tightly in contact with each other when the coupling body is coupled to the lifting bar by the fifth threads being coupled to the second threads, the extension rod passes through the second through hole to be inserted into the controller body, the coupling body, and the lifting bar, the third threads and the fourth threads are screw-coupled to each other, and the extension rod is capable of vertically moving when the third threads and the fourth threads are unscrewed from a screw-coupled state and the guide films expand.
