Description of the Invention: [Technical Field] The present invention relates to a sunshade, and more particularly to a sunshade in which a curtain can be followed by a pull. [Prior Art] There are many types and types of general sunshade curtains. Figure 2 and Figure 2 are the new patents for the M257288 (US 2005/0236117 A1) “Spirited with a Day 2”. The curtain comprises: two parallel spaced rails 11, a fixing unit 12, a sunshade το13 rotatably mounted on the fixing unit 12, a retractor 胄14, and two mounted on the sunshade 13 Internal torsion member 15. The fixing unit 12 includes two spaced apart fixing seats 121, and a connecting rod 122 rotatably mounted between the fixing seats 121. The sunshade unit 13 includes a reel 131 and two of the reel 131 The link 122 is coupled to the joint seat 32, and the sheet is wound around the outer surface of the spool 131. The take-up mechanism 14 includes two reel 141 which are sleeved at opposite ends of the cup 122 at right and left intervals. 'Two wire pulleys 142 respectively mounted at the ends of the tracks j 1 and two draw wires 143 respectively wound around the same side of the wire wheel 142 and one end wound on the reel 141, the other of the drawstrings 143 One end is fixed to a deployment portion 134 of the curtain 133, and the torsion members 15 are sleeved on the link 122 in a bilaterally symmetric manner, and are connected to the joint seat 132 and the reel 141 on the same side. The twisting member 15 is slightly twisted to have a torsional force during assembly, while the pull cord 143 and the cord 133 are maintained in a balanced state with a slight tension. 201237256 When the user pulls or pushes the unfolding portion i34 of the cord 133, the pulling of the cords 143 and the winding of the reels 141 can achieve the purpose of allowing the curtain 133 to follow the pull. The pull-and-go function of the aforementioned novel patent mainly comes from the fact that the torsion member 15 is pre-rotated with a torsional force during assembly, and the pull cord 143 and the curtain are maintained in an equilibrium state. However, in the assembly, the torsion member 15 needs to have a large torsional force to reach an equilibrium state, and how to make the torsion members 15 on both sides generate the same torsion force, which is not easy to control, so the aforementioned new patent is troublesome in grouping. . On the other hand, since the end of the drawstring 143 is fixed to the deployment portion 134 of the curtain 133, the other end must be wound away from the wire wheel 142 of the fixed single 12 and then re-wound around the winding. On the wheel (4), the rope body is long, and it is easy to cause entanglement and unsatisfactory problems during operation.
