ABSTRACT

The disclosure relates to a descending stroke adjustable device for a lifting
tool. The lifting tool includes a frame and a support rod. The support rod is
axially arranged in a penetrating manner in the frame. A descending stroke
adjustable device is mounted out of an upper end of the frame and includes a
height descending device and a stroke adjusting device. The height descending
device is penetrated by the support rod, and a descending stopping spring is
compressively mounted between the height descending device and an upper end
surface of the frame so that the height descending device and the support rod
keep a descending stopping inclination angle; and the stroke adjusting device
achieves an adjustable step-down stroke by accurately controlling an up-down
moving range when the height descending device is pressed.
