Abstract: The disclosure provides a vehicle-mounted bicycle stand, including a mounting seat, a support rod, a bracket and a locking and fixing mechanism, wherein the mounting seat is connected with a square-opening base at a rear end of a vehicle, and a connecting part is arranged at an end of the mounting seat; the support rod is fixed on the mounting seat; the bracket is rotationally mounted at an upper end of the support rod and is configured to place a bicycle; and the locking and fixing mechanism is mounted between the support rod and the bracket and is configured to lock and fix the bracket in a rearward unfolded state or a downward folded state. The vehicle-mounted bicycle stand of the disclosure is compact in structure, convenient and labor-saving in mounting and dismounting, high in overall structural strength, and good in reliability.

Abstract: The present disclosure provides a hydraulic jack, including a base as a carrier for mounting other components; an inner cylinder barrel vertically fixed to the base, a sliding cavity being formed in the inner cylinder barrel; an outer cylinder barrel vertically and slidably fitted outside the inner cylinder barrel; a valve plug assembly slidably fitted in the sliding cavity, and the valve plug assembly being rigidly connected to the outer cylinder barrel via a valve plug rod and being able to slide synchronously with the outer cylinder barrel; a valve plug driving assembly mounted on the outer cylinder barrel; and a supporting component mounted on the side wall of the outer cylinder barrel in an up-down adjustable mode. The hydraulic jack of the present disclosure is compact in structure, high in strength, high in load capacity, long in stroke, and safe and reliable in use.
