    摘要： Electrical telescopic strut construction, movable between an extended locked position and a retracted unlocked position, comprising:
    - an external cylinder (1);
    - an inner cylinder (2);
    - a screw (3) rotatable disposed within the inner cylinder (2);
    - a drive (4) configured to rotate the screw (3);
    - a nut (5) being movable with respect to the external cylinder (1) responsive to the rotation of the screw (3);
    - at least one segment (6) located in a radial opening of the inner cylinder (2) and movable radially outward and inward in response to the movement of the nut (5) and configured to engage the external cylinder (1) when moved radially outward and not to engage the external cylinder (1) when moved radially inward,
    - a second inner cylinder (7) located external to the first inner cylinder (2) and internal to the external cylinder (1).

    摘要： A jack assembly including a telescopic column driven via a gear box, wherein: the gear box is coupled to a rotary input of a drive mechanism that extends and retracts the column; the gear box has only a single input gear and a single output gear that is coupled to the drive mechanism; and the input gear has a connector adapted to be engaged and driven by a portable, hand-held power tool. The invention also relates to a jack assembly with a gear box for use as a jockey wheel for attachment to a towed vehicle, to raise and lower a draw bar of the vehicle.
