2. The shopping cart support frame welding support device according to claim 1, characterized in that: A transverse tube (13) is formed between the rear parts of the two support tubes (7).

3. The shopping cart support frame welding support device according to claim 2, characterized in that: A crimping assembly (12) for crimping the transverse tube (13) is installed on the supporting base plate (1).

4. The shopping cart support frame welding support device according to claim 3, characterized in that: The crimping assembly (12) comprises a rotating cylinder (121), a crimping column (122) and a third U-shaped seat (123); the rotating cylinder (121) and the two third U-shaped seats (123) are fixedly mounted on the supporting base plate (1), the crimping column (122) is fixedly connected to the output end of the rotating cylinder (121), and the transverse tube (13) is plugged into the top of the third U-shaped seat (123).

5. A method for using the shopping cart support frame welding support device according to claim 4, characterized in that: The following steps are involved:

1. First, place the support tube (7) on the top plate (64), then clamp the support tube (7) and the first U-shaped seat (62), and then drive the first rotating plate (33) to rotate through the first cylinder (31). When the first rotating plate (33) contracts, it drives the U-shaped pressing plate (34) to rotate and open to release the support tube (7). When the first rotating plate (33) extends, it drives the U-shaped pressing plate (34) to rotate and press on the support tube (7), thereby pressing the support tube (7); the transverse tube (13) is plugged into the third U-shaped seat (123), and then the pressing column (122) is driven by the rotating cylinder (121) to rotate and press on the transverse tube (13); Second, first start the fourth cylinder (85) to drive the transverse moving plate (81), the movable plate (83), the second L-shaped pressing plate (84), and the third L-shaped pressing plate (86) to move forward to make way, and the movable plate (83) is misaligned with the fixed seat (87), and then the end of the support frame (9) is plugged into the second U-shaped seat (89), and the middle part is plugged into the plug-in slot (88), and then the fourth cylinder (85) is started to drive the transverse moving plate (81), the movable plate (83), the second L-shaped pressing plate (84), and the third L-shaped pressing plate (86) to move backward, and the second L-shaped pressing plate (84) and the third L-shaped pressing plate (86) correspond to the positions of the plug-in slot (88) up and down, so that the second L-shaped pressing plate (84) and the third L-shaped pressing plate (86) are pressed on the support frame (9); 3. The second cylinder (42) drives the side plate 1 (43) to move outward, and then the side plate 2 (10) is inserted into the groove (45). Then, the second cylinder (42) is started to drive the side plate 1 (43) to move inward, and the side plate 1 (43) drives the insertion rod (46) to be inserted into the side plate 2 (10), thereby limiting the vertical position of the side plate 2 (10); by starting the third cylinder (51), the rotating connection block (52) is driven to rotate, and the rotating connection block (52) drives the first L-shaped pressing plate (53) to be pressed against the side plate 2 (10).
