State switching method and carrying tool using same

The invention discloses a state switching method and a carrying tool using the same. The carrier comprises a push handle, a vehicle body, a front wheel set and a rear wheel set, and the state switching method comprises the following steps: a detection step: detecting use parameters, judging the advancing direction of the carrier and generating a state signal; an execution step: generating an execution action after receiving the state signal; and a switching step, wherein the front wheel set and the rear wheel set are controlled to be switched between a directional state and a universal state after the execution action is received. According to the state switching method and the carrying tool, linkage of the fixed universal direction of the front wheel set and the rear wheel set of the carrying tool and the advancing direction of the carrying tool is achieved in an intelligent electric control mode, a large number of traction cable mechanism assemblies are omitted, efficiency is higher, reliability is better,
