Thrown frame capable of being assembled into a casing

A thrown frame capable of being assembled into a casing comprising:

• a case body having at least one open end;
• at least one thrown object being installed in the case body;
• a winding rod at a bottom of the case body for winding a protecting net;
• if the protecting net is not used, the protecting net can wind around the winding rod for limiting a movement space of a ball;
• a seat formed by a U shape rod;
• an upper transversal side of the U shape rod being firmly secured to the protecting net;
• a bottom of the U shape rod being connected to a transversal rod;
• a lower end of each of the two lateral sides of the U shape rod being pivotally and approximately vertically installed with a telescopic rod, which are a first telescopic rod and a second telescopic rod;
• the first telescopic rod and second telescopic rod extending toward the case body;
• each of the first telescopic rod and second telescopic rod being positioned to the lower end of the U shape rod by a V shape foldable rod;
• wherein when the thrown frame is not used, the first and second telescopic rods are compressed;
• then the telescopic rods are folded to be adhered to the U shape rod;
• then the seat is placed in the case body and the protecting net is wound around the winding rod;
• thus, the whole structure is stored in the case body.
