千斤顶位于坡立谷残丘地带，出露地层为泥盆系东岗岭组。上部岩石崩落，压在下部的岩石上，接触面较小，形似顶起重物的千斤顶，故而得名。下部岩石呈现明显的厚层灰岩和中薄层灰岩互层现象。

Grotesquely-shaped rock (Lifting jack) is located in the residual dome of polje, and the exposed stratum is the Devonian Donggangling Formation. The upper part of the rock collapsed and pressed on the rock below with a relatively small contact surface, which resembles a lifting jack for lifting heavy objects. The rock below is interbedded with thick and medium-thin limestone.
