[0014] The utility model provides a kind of traction rope controller and sunshade, compared with prior art, its beneficial effect lies in:

[0015] When using the traction rope controller of this utility model, the traction rope is wound on the rope reel. When it is necessary to retract the sunshade panel of the sunshade, the rotating part is rotated forward by operating the tool. When the rotating part rotates forward until the forward rotating push part contacts the forward rotating force-bearing part of the clamping spring, the elastic force of the clamping spring is released, and it is released from the clamping part. The clamping spring rotates with the rotating part. After the forward rotating force-bearing part of the clamping spring contacts the baffle, it drives the rope reel to rotate. The traction rope is wound on the lifting plate. The traction rope drives the sunshade to retract. When the sunshade is retracted to the required position, the rotating part stops rotating, the clamping spring is clamped to the clamping part, and the baffle and the forward rotating force-bearing part of the clamping spring stop the rope reel from rotating, so that the sunshade is kept in the retracted state. When the sunshade needs to be unrolled, the rotating component is reversed by the operation. When the rotating component rotates in the reverse direction until the reversing push part contacts the reversing force-receiving part of the clamping spring, the spring force is released, and the clamping spring is released from the fixing part. The clamping spring rotates with the rotating component, and after the reversing force-receiving part of the clamping spring contacts the baffle, it drives the rope reel to rotate. Under the action of the weight of the sunshade, the traction rope is unrolled from the rope reel. When the sunshade is unrolled to the desired position, the rotating component stops rotating, the clamping spring locks onto the fixing part, and the baffle and the reversing force-receiving part of the clamping spring stop the rope reel from rotating, thus keeping the sunshade in the unrolled state. This utility model's traction rope controller can realize the winding and unwinding operations of the sunshade through a single winding and unwinding mechanism, which is less prone to misoperation and more convenient to use.
