The invention discloses a foldable trolley capable of controlling a jack in a telescopic mode, and relates to the technical field of jacks, the trolley comprises a movable chassis, an oil return valve connecting mechanism, a telescopic push-pull rod capable of swinging and an oil return valve control mechanism, and the oil return valve connecting mechanism comprises a rear clamping sleeve, a front clamping sleeve and an upper clamping sleeve; the rear clamping sleeve and the upper clamping sleeve are respectively connected with the front clamping sleeve through corresponding transmission mechanisms; the oil return valve control mechanism comprises a rotary oil return valve control rod arranged in the telescopic push-pull rod and a control rod unlocking mechanism arranged on the outer side of the telescopic push-pull rod, the telescopic push-pull rod can drive the oil return valve control rod to stretch out and draw back synchronously when stretching out and drawing back, and a slipknot bolt is arranged on the oil return valve control rod. The operating rod unlocking mechanism can drive the slipknot bolt to move in the axial direction of the oil return valve operating rod, and the slipknot bolt can drive the oil return valve to rotate when matched with the front clamping sleeve or the upper clamping sleeve. And when the slipknot bolt is separated from the front clamping sleeve and the upper clamping sleeve, the oil return valve control mechanism can rotate. The oil return valve of the jack is easy and convenient to control.
