AI Technical Summary
The existing trolley push rod is prone to bending under stress during folding, affecting control stability, and its large size after folding makes it inconvenient to store.
The main and auxiliary support frames are positioned using a snap-fit and slot structure, combined with elastic elements and connectors to achieve stable unfolding and convenient folding of the push rod. Positioning edges and clearance slots ensure structural stability, and fasteners secure the connecting rods to ensure stability during use and ease of storage.
It achieves stability during use and compact storage after folding, avoiding the problem of the push rod bending under stress during use, while minimizing the folded volume for easy carrying and storage.

Abstract
Claims
1. A folding structure for a handcart push rod, characterized in that: It includes a main support frame (1) and a secondary support frame (2) rotatably connected to one side of the main support frame (1). The main support frame (1) is rotatably provided with a buckle (3) on its side, and the secondary support frame (2) has a slot (4) that matches the buckle (3) on its side, so that when the buckle (3) is fastened in the slot (4), the main support frame (1) and the secondary support frame (2) are positioned relative to each other.
2. The stroller push rod folding structure of claim 1, wherein: The buckle (3) has a protruding positioning part (5) at its end. The positioning part (5) matches the slot (4), and both the slot (4) and the positioning part (5) have inclined positioning surfaces (6) on their sides, so that the slot (4) and the positioning part (5) fit together through the positioning surfaces (6).
3. The stroller push rod folding structure of claim 2, wherein: The end of the buckle (3) away from the slot (4) is connected to the main support frame (1) by an elastic element (7). The buckle (3) has a pressing part (8) near the elastic element (7) so that when the pressing part (8) is pressed, the positioning part (5) disengages from the slot (4).
4. The stroller push rod folding structure of claim 1, wherein: The auxiliary support frame (2) has a positioning edge (9) and a clearance groove (10) on both sides of one end of the slot (4) so that when the main support frame (1) and the auxiliary support frame (2) are positioned relative to each other, the side of the main support frame (1) abuts against the positioning edge (9), and when the auxiliary support frame (2) is folded relative to the main support frame (1), the clearance groove (10) moves toward the main support frame (1).
5. The stroller push rod folding structure of claim 1, wherein: It also includes a connector (11) and a corner bracket (12) rotatably connected to the side of the connector (11). One end of the connector (11) is provided with a first connecting groove (13), and the ends of the main support frame (1) and the auxiliary support frame (2) are provided with a second connecting groove (14) so that the first connecting groove (13) and the second connecting groove (14) are connected by a connecting rod.
6. The folding structure of the handcart push rod according to claim 5, characterized in that: The connector (11) has a movable groove (15) on its side, and the corner frame (12) has a movable block (16) on its side that moves in conjunction with the movable groove (15), so that when the corner frame (12) rotates relative to the connector (11), the movable block (16) moves along the movable groove (15).
7. The stroller push rod folding structure of claim 5, wherein: The corner bracket (12) has a third connecting groove (17) at one end.
8. The stroller push rod folding structure of claim 7, wherein: The first connecting groove (13), the second connecting groove (14) and the third connecting groove (17) are all provided with fastening holes (18) on their sides. After the fastener passes through the fastening hole (18), it tightens the connecting rod.
