[0002] Hydraulic jack, also known as oil jack, is a jack that uses a plunger or hydraulic cylinder as a rigid jacking piece. It is a simple lifting equipment, generally only equipped with a lifting mechanism to lift heavy objects. It has a simple structure, light weight, and is easy to carry and move. Hydraulic jacks are divided into general and special types. General hydraulic jacks are suitable for various lifting operations with low lifting heights.

In some special cases, some heavy objects do not have enough space at the bottom, so the jack cannot be placed under the heavy objects, making the jack unusable. In order to facilitate the use of the jack, this scheme proposes a hydraulic jack with adjustable support angle. Utility Model Content
