The invention relates to a hydraulic clamping hand for a
bottle cap. The hydraulic clamping hand for the
bottle cap comprises a supporting plate, a movable block, clamping jaws, a guiding rod, connecting plates, a
hydraulic cylinder and springs, wherein the movable block is matched with the supporting plate in a sliding mode; the clamping jaws are distributed symmetrically and hinged to the movable block; the guiding rod is matched with the movable block in a sliding mode; one end of each of the connecting plates is hinged to the guiding rod, and the other end of each of the connecting platesis hinged to each of the clamping jaws; the
hydraulic cylinder is used for pushing the guiding rod to move in the extending process; one end of each of the springs is connected to the movable block, and the other end of each of the springs is connected to the
hydraulic cylinder. The clamping jaws are of curved arc-shaped structures which close to each other, and clamping plates with the same curving direction as the clamping jaws are connected to the clamping jaws. According to the hydraulic clamping hand for the
bottle cap, structural design is reasonable, operation is simple, using is convenient, the effective contact surface between the clamping hand and the
bottle cap is increased, the stability and assembling precision during clamping of the
bottle cap are greatly improved, the lengthof the clamping hand is greatly prolonged, the installation of the
bottle cap and a
wine bottle is facilitated, and the cap pressing of the bottle is facilitated.
