The middle area of the first body part 43 can be processed into an inward concave shape by adopting but not limited to a stamping process, the strength of the first body part 43 in the weak axis direction (shown in the Y direction in fig. 6) can be effectively increased, the first pulling piece 40 is not easy to deform in the weak axis direction under the action of external force, the effect of enhancing the plane external rigidity of the first pulling piece 40 is achieved, and then the strength of the first wall plate 11, the second wall plate 12, the third wall plate 13 and the fourth wall plate 14 which are connected together through the first pulling piece 40 is improved.

In some possible embodiments, the thickness of the concave surface 48 protruding the back surface 47 of the first body portion 43 is between 1mm and 3mm, including 1mm and 3mm, such as 1.8mm, 2.2mm, and the like. This is advantageous in that the strength in the weak axis direction of the first body portion 43 is increased with a reduced thickness of the first body portion 43.

In some possible embodiments, the middle region of the first body portion 43 is formed with an inner concave surface 48 in a direction from the back surface 47 to the front surface 46 of the first body portion 43, the inner concave surface 48 protruding the front surface 46 of the first body portion 43.
