The invention discloses an unequal-thickness box type arm support which comprises a top plate, a bottom plate, side plates and a mounting plate. The side plates comprise the first side plate and the second side plate, the first side plate and the second side plate are perpendicular to the top plate, and the upper end of the first side plate and the upper end of the second side plate are connected with the two side edges of the top plate respectively. The bottom plate comprises a first bottom plate body and a second bottom plate body, the outer side edge of the first bottom plate body is connected with the bottom end of the first side plate, the outer side edge of the second bottom plate body is connected with the bottom end of the second side plate, the inner side edge of the first bottom plate body is connected with the inner side edge of the second bottom plate body, and the first bottom plate body and the second bottom plate body are parallel to the top plate. The top plate, the first side plate, the first bottom plate, the second bottom plate and the second side plate are sequentially connected to form a square pipe; the mounting plate is bent along the outer contour of the square tube, the section of the mounting plate is in an n shape, the mounting plate is arranged at one end of the square tube in a sleeving mode and connected with the square tube, symmetrical mounting holes are formed in the two sides of the mounting plate, and the production efficiency can be greatly improved.
