A single-handed remote controller is disclosed. Such a controller is installed at the handle of an accordion frame and is connected to a lock mechanism of the frame through a flexible element. As the remote controller rotates relative to the handle, the flexible element is coiled around the handle, changing the relative position between the lock mechanism and the handle. The frame is thus changed to make the folding much easier.

1. A single-handed remote controller applied to a handle on a frame that has a folded state and an extended state and a lock mechanism for locking its extended state, the single-handed remote controller comprising:a cover, which is installed on the handle to rotate relative to the handle and has a snap mechanism to constrain the cover in a fixed position and a mobile position; anda rotator, which is installed on the handle and connected to the lock mechanism through a flexible element, and rotates with the cover relative to the handle when the cover is in its mobile state so that the flexible element changes the relative positions of the lock mechanism and the rotator by coiling around, which in turn changes the state of the frame, the flexible element changes the relative positions of the lock mechanism and the rotator by coiling around the handle as the cover rotates with the rotator, which in turn changes the state of the frame. 2. The single-handed remote controller of claim 1, wherein the cover comprises a first outer cover, a second outer cover combined with the first outer cover, and two connectors connected to the two ends of the first outer cover and the second outer cover. 3. The single-handed remote controller of claim 2, wherein the first outer cover and the second outer cover are fixed and connected through a screw. 4. The single-handed remote controller of claim 2, wherein the first outer cover and the second outer cover are fixed and connected through a rivet. 5. The single-handed remote controller of claim 2, wherein the outer covers and the connectors have an engagement area for their combination. 6. The single-handed remote controller of claim 1, wherein the snap mechanism comprises a lock ring mounted on the outer rim of the handle and an elastic element sandwiched between the lock ring and the handle, the lock ring being further installed with a post that is constantly pushed by the elastic element against the hole on the handle and leaves the hole when the elastic element is depressed. 7. The single-handed remote controller of claim 6, wherein the lock ring is formed with a pressure-bearing block protruding from its surface. 8. The single-handed remote controller of claim 1, wherein the cover and the rotator have an engagement groove for their combination.
