In the unlocked state, the upper fence bracket is driven close to the lower fence bottom plate, one end of the two support rods rotates, and the other end slides, so that the upper fence bracket fits the lower fence bottom plate, so that the basket can be folded; however, with the above solution, the structure of the deployment and folding of the basket is complicated, and multiple connectors and locking components are required, with a high failure rate, prone to instability and safety hazards, and increased manufacturing costs of the basket. Moreover, during the deployment and folding process, it is first necessary to lock and unlock the basket separately before further operations can be performed. There are many operations and the operation is cumbersome, which reduces the user experience.
