7 . The pull handle device according to claim 1 , wherein the handle comprises a first part connecting the two rods and a second part fixed above the first part, the second part enclosing an upper surface of the first part and a part of both sides of the first part; and

wherein an upper portion of the second part forms the hanging structure.

8 . The pull handle device according to claim 7 , wherein a lower portion of the first part forms two rod connecting portions for connecting the two rods respectively.

9 . The pull handle device according to claim 7 , wherein a parting line is provided between the second part and the first part, and

wherein the parting line comprises a straight-line portion in the middle and arc portions on both sides of the straight-line portion.

10 . The pull handle device according to claim 9 , wherein a minimum distance from the inclined portion to the parting line in the first direction is not less than ½ of a minimum distance from the gripping structure to the parting line in the first direction; and

wherein a minimum distance from the curved portion to the parting line in the first direction is not less than ½ of a minimum distance from the gripping structure to the parting line in the first direction.

11 . The pull handle device according to claim 7 , wherein the first part and the second part enclose to form an accommodating space,

wherein a button mechanism is provided inside the accommodating space, and

wherein a part of a button of the button mechanism protrudes from the second part.

12 . The pull handle device according to claim 11 , wherein the first part and the second part are fixedly connected by one or more fasteners;

wherein one of the first part or the second part is provided with a positioning hole, the other of the first part and the second part is provided with a first positioning post, and the fastener passes through the positioning hole and is fixedly connected to the first positioning post; and

wherein the first positioning post is located within the accommodating space, and the first positioning post abuts an inner wall of one of the first part and or second part.

13 . The pull handle device according to claim 7 , wherein the first part and the second part enclose to form an accommodating space;

wherein the first part is provided with a positioning protrusion, the second part is provided with a second positioning post, and the second positioning post abuts the positioning protrusion; and

wherein a range of a projection of the second positioning post along the second direction is within a range of a projection of the two rods along the second direction.

14 . The pull handle device according to claim 1 , wherein side walls of the handle on both sides of the handle in the second direction are curved; and

wherein the side walls of the handle on both sides of the handle in a third direction are curved, the third direction being perpendicular to the first direction and the second direction.

15 . The pull handle device according to claim 1 , wherein a range of a projection of the groove along the second direction is within a range of a projection of the two rods along the second direction.
