[0034] Please refer to FIGS. 5 to 8 for the principle of the folding process of the present application, in which the gathering trailer, when folded, first pulls the lifting member 55 upward, so that the four lifting rods around it near the side of the lifting member 55 are also lifted upwardly, and the four lifting rods away from the side of the lifting member 55 are gradually closed in the direction of the lifting member 55, driving the four columns to gradually close in the direction as well. At this time, the angle between the end portions of the first left-right adjusting lever 41 and the fourth left-right adjusting lever 44 becomes smaller, the angle between the first left-right adjusting lever 41 and the second left-right adjusting lever 42 and the third left-right adjusting lever 43 and the end portion of the fourth left-right adjusting lever 44 is also reduced, and the angle between the fifth left-right adjusting lever 45 and the sixth left-right adjusting lever 46 and the sixth left-right adjusting lever 46 and the second left-right adjusting lever 42 and the second left-right adjusting lever 42 The angle between the third left-right adjusting rod 43 and the third left-right adjusting rod 43 and the seventh left-right adjusting rod 47 and the seventh left-right adjusting rod 47 and the end of the eighth left-right adjusting rod 48 also becomes smaller, and the process of contracting and gathering of the eight left-right adjusting rods is gradually completed. The angle between the first front and rear adjusting rod 31 and the second front and rear adjusting rod 32 and the third front and rear adjusting rod 33 and the end of the fourth front and rear adjusting rod 34 becomes smaller, while the angle between the first front and rear adjusting rod 31 and the third front and rear adjusting rod 33 and the second front and rear adjusting rod 32 and the fourth front and rear adjusting rod 34 becomes larger, and gradually completes the process of contracting and gathering of the four front and rear adjusting rods, and after being unfolded, a cloth bag is put in the center of the four rods for holding a cloth bag. A cloth bag is placed between the four poles to hold the articles. When the article is driven forward by the trailer in the cloth bag, it will swing from side to side, which is equivalent to applying a thrust force to the plane where the first upright 21 and the second upright 22 or the third upright 23 and the fourth upright 24 are located, and due to the symmetrical triangular region formed between the first left-right adjusting rod 41 and the fifth left-right adjusting rod 45 as well as the fourth left-right adjusting rod 44 and the eighth left-right adjusting rod 48, the triangular region also has a stability. Therefore, the pushing force does not easily deform the triangle, and at the same time, the sixth left-right adjusting rod 46 and the seventh left-right adjusting rod 47 play a supporting role for the fifth left-right adjusting rod 45 and the eighth left-right adjusting rod 48 respectively at the bottom, which further reinforces the stability of the triangle, and therefore it is difficult for the triangle to deform even if the weight of the article is heavier and the swinging amplitude is larger, the first vertical rod 21, second vertical rod 22, third vertical rod 23 and fourth vertical rod 24 will not be prone to the occurrence of the left and right tipping phenomenon.

[0035] Finally, it should be noted that the above mentioned are only the preferred examples of the present application and are not intended to limit the present application. Notwithstanding the detailed description of the present application with reference to the foregoing embodiments, a technician skilled in the art may still modify the technical solutions recorded in the foregoing embodiments or make equivalent substitutions for some of the technical features therein. All modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
