Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in figure 2, the adjustable oil cylinder safety support comprises a fixed support 1, an adjusting support 2, a large clamp 3 and two small clamps 4. The upper end of the fixed support 1 is connected with a small hoop 4, and the lower end of the fixed support 1 is connected with a large hoop 3. The lower end of the adjusting bracket 2 is connected with a small hoop 4, and the upper end of the adjusting bracket 2 is slidably arranged between the large hoop 3 and the fixed bracket 1.
