SUMMARY OF THE INVENTION There is no improvement in the design of the car in the car, and the inventor of the present invention has refined the concept, and has carefully studied and improved the above-mentioned defects, and has been able to create the present invention first. The object of the present invention is to provide a structure that can be combined with the bottom end of the main rod of the vehicle rear compartment 200900292. The structure of the frame is improved, including the two main poles and the top of the sleeve. The inner n piece of the fitting is 'the bottom end of the two main rods is attached to the fitting member; 5, and the two main rods are respectively provided with the bottom end suitable for the surrounding portion; the fitting piece, The inner part is a circular groove, and the screw hole is available for the screw; j: the snail. The hole is connected with the circular groove, and one of the struts is "two ^ shai two main pole tops are suitable Between the two pivots, the above design has the following advantages: The lower end of the 4 piece is folded inside the folded piece, and is opened or closed with the lower end member; === fulcrum The action is 'user': the outer shape is even more in use, and the round groove of the sleeve provided at the lower end of the rear compartment of the carriage is sleeved in the circular groove of the automobile part locking screw to the sleeve Because it combines the combination of the cultivar and the car, it is poor, and it is completely covered at 2°. No matter how big the ball diameter of the ball is, it will be shaken by the screw. Tight, so it is not combined at all, swaying, and better stability. [Embodiment] The third embodiment of the structure is shown in Fig. 1) 'The car frame (3) and the 3 trusses of the car of the present invention ( 30), the fitting member (31), the folding member (310), the core L f piece () H main rod (3G) bottom end is attached to the fitting member (30) and is combined with the folding member (310) The inner part is folded, and the two main parts are arranged such that the bottom end thereof is suitable for the wall surface of the folding piece (310), and the rivet is adjusted by the rivet, and the fitting part (31) is internally a circular groove (312), wherein the edge is provided with a plurality of screw holes (313), the screw hole (313) is in communication with the circular groove (312), and the screw hole (313) is available for the screw (34) The two main poles (30) 6 200900292 are erected at one end of each of the two pivoting outer struts (32) (see the fourth and fifth figures) to make the carrying frame (3) Opening open and fitting the bottom end fitting (31) to the ball portion (40) of the rear seat support (4) of the automobile, and screwing the screw (34) into the ball portion (40) The combination of the carrying frame (3) and the automobile can be completed; the screw (34) is loosened, and the fitting (31) is separated from the ball portion (40) of the rear support bracket (4) of the automobile. The carrier frame (3) can be folded. [Simplified illustration of the drawing] The first figure is a conventional folding diagram. The second figure is a conventional clamping diagram. The third figure is a perspective view of the fourth figure of the present invention. The fifth drawing of the present invention is a schematic view of the folding of the present invention.
