With the above-mentioned structure, when in use, the locking member 300 is rotated to the locking position, and the locking member 300 is inserted into the locking groove 221. The locking member 300 hinders the rotation of the fixed caster 220, and then hinders the movement of the cart, so that the cart can be stably parked in place, and the use is safer; when the locking member 300 is rotated to the unlocking position, the locking member 300 is detached from the locking groove 221, and the fixed caster 220 can rotate freely, which is convenient for users to push, pull, and move the cart, and the moving product is convenient and labor-saving.

[0068] In this embodiment, the locking member 300 includes a pedal 310 and a locking rod 320 connected to the outer side of the pedal. The pedal 310 is used to allow the user to step on or lift it. The locking rod 320 is inserted into or detached from the locking groove 221. Through the above-mentioned structure, the pedal 310 is provided, which can facilitate the user to rotate the locking member 300. When in use, the user only needs to step on the pedal 310 downward to insert the locking rod 320 into the locking groove 221 to complete the fixing of the fixed caster 220; and when the fixed caster 220 needs to be unlocked, it is only necessary to lift the pedal 310 upward. The user does not need to bend down during the operation, and the operation is simple.

[0069] In this embodiment, the locking rod 320 includes locking parts 321 on both sides, a connecting part 322 in the middle, and a curved transition part 323 between the locking part 321 and the connecting part 322. The pedal 310 is connected to the connecting part 322. The locking part 321 is inserted into or detached from the locking groove 221. The transition part 323 extends outward in a direction away from the first bracket assembly 110. Through the above-mentioned structure, the curved transition part 323 can make the connecting part 322 and the pedal 310 arranged at the connecting part away from the first bracket assembly 110, increase the distance between the pedal 310 and the first bracket assembly 110, and when the user steps on or lifts the pedal 310, the operation is easier and simpler, and the rotation torque is increased, which can make the rotation of the locking member 300 more labor-saving.

[0070] In this embodiment, the upper surface of the pedal 310 is provided with friction lines 311. Through the above-mentioned structure, the friction lines 311 can increase the friction coefficient of the upper surface of the pedal 310, and when the user steps on the pedal 310, the friction between the user's sole and the upper surface of the pedal 310 is increased, so that the user can step down the pedal 310 more easily, and the operation is simple.

[0071] In this embodiment, a plurality of clamping members 400 are further included. The clamping members 400 are provided with openings facing downwards. The clamping members 400 are clamped on the upper connecting bracket assembly. The clamping members 400 are used to clamp and fix the bushing 500 to the upper connecting bracket assembly. Through the above-mentioned structure, the clamping members 400 are roughly "C"-shaped. The opening allows the bushing 500 and the upper connecting bracket assembly 131 to pass through. The clamping members 400 connect the bushing 500 to the upper connecting bracket assembly 131, which can prevent the bushing 500 from slipping or detaching, thereby ensuring the stability of the product.

[0072] In this embodiment, a plurality of support members 180 are further included, and the support members 180 are connected to the upper portion of the first bracket assembly 110 and / or the upper portion of the second bracket assembly 120, and the support members 180 are used to support the shielding cover 600. Through the above-mentioned structure, when in use, the shielding cover 600 is connected to the top of the support members 180, and the shielding cover 600 can be stably connected and fixed, effectively shielding from the sun and rain, and improving the user's experience; preferably, the support members 180 can be detachably connected to the upper portion of the first bracket assembly 110 and / or the upper portion of the second bracket assembly 120, and when the shielding cover 600 is not needed, the support members 180 can be removed to reduce the product volume.

[0073] In this embodiment, a supporting member 190 is also included, and the supporting member 190 is connected to the middle of the first bracket assembly 110 and extends in a direction away from the first bracket assembly 110. The supporting member 190 is used to support the accommodating sleeve 700. Through the above-mentioned structure, when in use, the accommodating sleeve 700 can be connected to the supporting member 190 to form an accommodating space, and sundries such as paper towels and umbrellas can be stored in the accommodating space. In addition, the supporting member 190 is arranged in the middle of the first bracket assembly 110 and extends in a direction away from the first bracket assembly 110. It is located below the push rod assembly 171, and does not increase the lateral volume of the product. The space below the push rod assembly 171 can be reasonably utilized, and it is closer to the user, which is convenient for the user to take and store items.
