Description

Technical Field

[0001] The utility model relates to the field of brackets, and more specifically to a hydraulic double telescopic bracket. Background Art

[0002] A hydraulic rod is an object that pushes a connecting rod through hydraulic pressure. Most existing hydraulic rods use a single connecting rod to connect objects, and the two ends of the single connecting rod are respectively connected to a liquid storage cylinder and an object. This makes it easy for the connecting rod to separate from the liquid storage cylinder or the object when an inclined external force acts on the side wall of the connecting rod. For this reason, we propose a hydraulic double telescopic bracket. Utility Model Content
