The invention discloses a hydraulically adjusted and controlled trailer device which comprises a fixed flat plate, a swing hollow pipe and a hook. The hook is arranged at the front end of the swing hollow pipe. The swing hollow pipe is arranged below the fixed flat plate. A first pin shaft is arranged between the rear end of the swing hollow pipe and the fixed flat plate, and therefore the rear end of the swing hollow pipe is hinged to the fixed flat plate. The fixed flat plate is provided with a slot. A swing block is hinged to the interior of the slot. A hydraulic damping rod is fixedly arranged on the swing block. A telescopic rod of the hydraulic damping rod penetrates through the swing block to point to the swing hollow pipe. A second pin shaft is arranged between the lower end of the telescopic rod and the front portion of the swing hollow pipe, and therefore the lower end of the telescopic rod is hinged to the front portion of the swing hollow pipe. In this way, according to the hydraulically adjusted and controlled trailer device, the vertical swing angle of the swing hollow pipe is adjusted by means of the hydraulic damping rod, so that the height and angle of the hook are changed and adjusted conveniently, and the trailing practicability is improved.
