Description

Technical Field

[0001] The utility model relates to the technical field of art teaching tools, in particular to a portable sketching easel for outdoor student teaching. Background Art

[0002] An easel is a free-standing structure designed to hold a canvas or drawing board while an artist is painting. Studio easels usually consist of four strong wooden bars fixed to a square or rectangular base with wheels, two sturdy support rods crossing at the top, and diagonal braces in the middle of the back. There is an adjustable slide with spring hooks that can hold and support the painting in sections; there is a movable clamp at the top to secure it.
