[0017] By adopting the above technical solution, two limiting blocks are arranged on the rear wheel rod to limit the rotation of the rear wheel rod, so as to further improve the connection stability and strength between the rear wheel rod and the push rod.
[0018] Preferably, two rotating plates are provided and are respectively arranged on two side walls of the rotating block, and a first reinforcing rib is arranged between the two rotating plates at intervals along the length direction thereof.
[0019] By adopting the above technical solution and providing the first reinforcing rib, the connection strength between the rotating plates is increased, so as to reduce the possibility of relative slippage between the rotating plates and the rotating blocks due to the influence of the gravity of the handbasket.
[0020] Preferably, second reinforcing ribs are provided between the rotating plate and the surface of the first vertical rod, and a plurality of second reinforcing ribs are provided at intervals along the length direction of the rotating plate.
[0021] By adopting the above technical solution, a second reinforcing rib is provided to improve the connection strength between the rotating plate and the first vertical rod, so as to further improve the connection strength between the T-frame and the front wheel frame.
[0022] In summary, the utility model has the following beneficial effects:
