Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 7 , the utility model provides the following technical solutions:

[0033] Example 1: In order to solve the problem that the adjustable pull rod on the market is relatively cumbersome in use due to the steps of adjusting the pull rod height, locking mechanism and upper box position, and the upper box is connected to the upper pull rod by a U-shaped buckle. Although it can move along the length direction of the upper pull rod, it may become unstable in the position of the upper box due to looseness or loose buckle during adjustment, making it impossible to adjust the pull rod quickly. In addition, the cross bar is fixed and the angle of the cross bar cannot be adjusted according to personal usage habits or comfort. Please refer to the attached Figure 1 and attached Figure 3 -Attached Figure 7The luggage body 1 has through-holes 6 formed on both sides. A pull rod 7 extends through these through-holes 6. Several locking holes 8 are formed on the front of the pull rod 7. A connecting plate 9 is fixedly mounted on the top of the pull rod 7. A mounting seat 10 is fixedly connected to the top of the connecting plate 9. A rotating rod 11 extends through the mounting seat 10, and a handle 12 is fixedly mounted at the end of the rotating rod 11. A groove 14 is formed on the front of the luggage body 1. A pull plate 15 is provided inside the groove 14. Locking rods 16 are fixedly mounted on the back of both sides of the pull plate 15, and the ends of the locking rods 16 extend through the locking holes 8. Movable slots 20 are symmetrically formed on both sides of the luggage body 1 within the grooves 14. A positioning bolt 13 extends through the left side of the rotating rod 11, and the end of the positioning bolt 13 extends through the mounting seat 10. A slide 21 is fixedly mounted on the bottom of the pull rod 7. A compression spring 22 is fixedly connected to the bottom of the slide 21, and the end of the compression spring 22 is fixedly connected to the inner bottom wall of the through-hole 6. Telescopic rods 17 are fixedly mounted behind the pull plate 15, on either side of the latching rod 16. The ends of the rods 17 extend through a movable slot 20. A slide plate 21 is fixedly mounted behind the rods 17, and a strong spring 19 is sheathed around the outer wall of the rods 17. The pull rod body 7 is movably connected to the through hole 6, while the pull rod body 7 and the latching hole 8 are integrally formed. The latching hole 8 and the pull rod 16 are also movably connected. The telescopic rod 17 and the movable plate 18 are also movably connected to the movable slot 20. The movable slot 20 is in communication with the groove 14, and the groove 14 is movably connected to the pull plate 15.

[0034] When the operator needs to adjust the pull rod for the double-sided composite bag, the operator manually grips the pull plate 15 through the groove 14 and pulls it outward, so that the pull plate 15 drives the card rod 16 to move outward, so that it disengages from the corresponding card hole 8. In the process of pulling the pull plate 15, each telescopic rod 17 is driven to move outward in the corresponding moving groove 20, so that the telescopic rod 17 drives the moving plate 18 to move outward and squeezes the strong spring 19, thereby increasing the stability and limit of the movement of the card rod 16. After the card rod 16 disengages from the corresponding card hole 8, the operator manually pulls the handle 12 By pulling upward or pushing downward, the handle 12 drives the rod body 7 connected to the mounting base 10 through the connecting plate 9 to move upward or downward in the corresponding through hole 6. After the rod body 7 moves to a suitable height, the pulled plate 15 is manually released, so that the rebound force of the strong spring 19 drives the pull plate 15 connected to the telescopic rod 17 to retract into the groove 14. At the same time, the pull plate 15 drives the clamping rod 16 to be inserted into the corresponding clamping hole 8, so that the rod body 7 is fixedly installed in the through hole 6 in the luggage body 1, thereby adjusting the rod, making it more convenient to drag the double-sided composite luggage;

[0035] When the user needs to adjust the angle of the handle 12, the positioning bolt 13 is manually pulled out from the rotating rod 11 to disengage the positioning bolt 13 from the mounting base 10. The operator then manually rotates the handle 12 so that the handle 12 drives the rotating rod 11 to rotate in the mounting base 10, thereby adjusting the handle 12 to a suitable angle. The positioning bolt 13 is then manually passed through the rotating rod 11 and reinserted into the mounting base 10 so that the rotating rod 11 is fixedly installed in the mounting base 10. The inclination angle of the handle 12 can be adjusted according to personal usage habits or comfort, making it more labor-saving and comfortable to drag the double-sided composite bag.
