# Descending stroke adjustable device for a lifting tool

## 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.
