It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1, the present invention provides a lifting stool 100, wherein the height of the lifting stool 100 can be adjusted so that a user can sit on or detach from the lifting stool, especially for assisting an elderly with mobility impairment.

The lifting stool 100 comprises a base 1, a seat cushion 2, a driving assembly 3 and a connecting rod assembly 4, wherein the driving assembly 3 is arranged on the base 1, one end of the connecting rod assembly 4 is movably connected to the base 1, and the other end of the connecting rod assembly 4 is movably connected to the seat cushion 2, so that the seat cushion 2 can move relative to the base 1 through the connecting rod assembly 4, and the height of the seat cushion 2 relative to the base 1 is adjusted.

One side of the base 1 is used to be placed on a supporting surface such as a floor so that the floor can support the elevating stool. The opposite side of the base 1 is provided with a fixed seat 11 and a first limiting strip 12.

The fixing seat 11 is rotatably connected with a first rotating rod 13, and the first rotating rod 13 is used for rotatably connecting the driving assembly 3, so that the driving assembly 3 can rotate relative to the base 1.
