Wherein: the first groove 110 and the second groove 120 are formed by bending plates, the third side wall 121 is attached to the inner side of the first side wall 111, the end parts of the first side wall and the end parts of the second side wall are connected, and the fourth side wall 123 is attached to the inner side of the second side wall 113, the end parts of the second side wall and the end parts of the fourth side wall are connected; the width of the third sidewall 121 is smaller than that of the first sidewall 111 and the width of the fourth sidewall 123 is smaller than that of the second sidewall 113, so that the second groove bottom 122 and the first groove bottom 112 are spaced apart.
