A universal and directional automatic switching wheel comprises a wheel body, a wheel fork, a wheel shaft and a wheel connector, a ratchet wheel and a pawl are arranged on the wheel body, the wheel body is connected to the wheel fork in a pivoted mode through the wheel shaft, the wheel fork is rotationally connected with the wheel connector, a rotation stopping mechanism is arranged between the wheel fork and the wheel connector, and the rotation stopping mechanism is connected with the wheel connector in a pivoted mode. The ratchet wheel is used for limiting rotation of the wheel fork and the wheel connector, when the wheel moves in the first direction, the pawl on the wheel cannot drive the ratchet wheel to effectively rotate, the rotation stopping mechanism takes effect, the wheel is a directional wheel, when the wheel moves in the second direction opposite to the first direction, the pawl on the wheel drives the ratchet wheel to effectively rotate, and the ratchet wheel is driven to effectively rotate. And when the rotation stopping mechanism fails, the wheel becomes a universal wheel.
