[0022] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installing and connecting should be understood broadly, and the person skilled in the art can reasonably determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.

[0023] Please see Figures 1-4 This utility model provides a technical solution: an adjustable luggage handle, including an adjustment mechanism mounted on the luggage body 1. The adjustment mechanism includes a fixed plate 3, a telescopic rod body 4, a sliding block 5, a protective shell 6, an L-shaped rod 12, a polygonal locking block 13, a limiting block 14, a moving block 15, a spring 16, a hollow rotating rod 17, and a polygonal locking groove 18. There are two fixed plates 3, both fixedly connected to the surface of the luggage body 1. The number of telescopic rod bodies 4 is the same as the number of fixed plates 3, and they are rotatably connected to their respective fixed plates 3. The protective shell 6 is fixedly connected to the surface of the luggage body 1. The sliding block 5... The sliding connection is inside the protective shell 6. There are two limiting blocks 14, both of which are fixedly connected to the surface of the bag body 1. The number of L-shaped rods 12 is the same as that of the limiting blocks 14, and they are slidably connected to the corresponding limiting blocks 14. The polygonal locking block 13 is fixedly connected to the L-shaped rod 12. There are two moving blocks 15, both of which are fixedly connected to the surface of the L-shaped rod 12. The spring 16 is fixedly connected to the opposite face of the two moving blocks 15. The hollow rotating rod 17 is fixedly connected to the surface of the telescopic rod body 4. The hollow rotating rod 17 is rotatably connected to the fixing plate 3. The polygonal locking groove 18 is opened inside the hollow rotating rod 17.

[0024] Furthermore, the cross-section of the polygonal slot 18 is the same as that of the polygonal block 13. The polygonal block 13 is slidably connected to the polygonal slot 18. The sliding block 5 is provided with a handle for easy movement. Sliding the sliding block 5 downwards allows it to contact the inclined surface on the moving block 15. Continuing to move the sliding block 5 downwards will cause the two moving blocks 15 to move closer to each other and move the L-shaped rod 12, causing the polygonal block 13 to disengage from the interior of the polygonal slot 18. This enables the hollow rotating rod 17 to rotate, allowing the telescopic rod body 4 to rotate to a suitable angle. Then, sliding the sliding block 5 upwards removes the limiting effect of the sliding block 5 on the moving block 15. The spring 16 then returns the moving block 15 to its original position and moves the L-shaped rod 12 back to its original position. Upon returning to its original position, the polygonal locking block 13 returns to the interior of the polygonal locking slot 18, again limiting the rotation of the hollow rotating rod 17, thereby limiting the telescopic rod body 4. The polygonal locking block 13 has multiple inclined surfaces on the side near the polygonal locking slot 18 to prevent jamming when it enters the interior of the polygonal locking slot 18. This allows the polygonal locking slot 18 and the polygonal locking block 13 to automatically align their cross-sections, achieving the tilting and fixing of the telescopic rod body 4. This changes the angle of the telescopic rod body 4, solving the problem that luggage handles are generally only equipped with length adjustment functions and cannot adjust the angle of the handle. This causes the luggage to tilt when pulled, which is inconvenient when liquids are placed inside the luggage or other packages need to be placed on top of the luggage.

[0025] Secondly, a rotating rod 8 is rotatably connected to the surface of the telescopic rod body 4, a connecting plate 7 is fixedly connected to the surface of the rotating rod 8, and a sliding rod 10 is fixedly connected to the surface of the connecting plate 7. The sliding rod 10 is slidably connected to the fixed plate 3. The fixed plate 3 has a groove 11 for limiting the sliding rod 10. A telescopic rod 9 is provided at the top of the telescopic rod body 4, and multiple rollers 2 are provided at the bottom of the bag body 1. The support plate at the top of each roller 2 is fixedly connected to the bottom of the bag body 1. The telescopic rod 9 is located inside the telescopic rod body 4 to realize the extension and retraction of the bag handle. This technology is mature enough and will not be elaborated here. The rollers 2 are used to facilitate the movement of the bag body 1. When the telescopic rod body 4 rotates, the rotating rod 8 can drive the connecting plate 7 to move, thereby causing the sliding rod 10 to slide on the groove 11. The connecting plate 7 is provided to enhance the stability of the telescopic rod body 4 when rotating, improve the overall stability of the device, and increase its service life.

[0026] Working principle: Sliding the sliding block 5 downwards allows it to contact the inclined surface on the moving block 15. Continuing to move the sliding block 5 downwards causes the two moving blocks 15 to move closer together, and moves the L-shaped rod 12, causing the polygonal locking block 13 to disengage from the polygonal slot 18. This allows the hollow rotating rod 17 to rotate, enabling the telescopic rod body 4 to rotate to a suitable angle. Then, sliding the sliding block 5 upwards removes its constraint on the moving block 15. The spring 16 returns the moving block 15 to its original position, causing the L-shaped rod 12 to return to its original position as well. The polygonal locking block 13 returns to the polygonal slot 18, once again engaging the hollow rotating rod 17. The rotation is limited, thereby limiting the telescopic rod body 4. The polygonal block 13 is provided with multiple inclined surfaces on the side near the polygonal slot 18 to prevent the polygonal block 13 from getting stuck when it enters the polygonal slot 18. This allows the polygonal slot 18 and the polygonal block 13 to automatically align their cross-sections, achieving the tilting and fixing of the telescopic rod body 4, thereby changing the angle of the telescopic rod body 4. When the telescopic rod body 4 rotates, the rotating rod 8 can drive the connecting plate 7 to move, thereby causing the sliding rod 10 to slide on the sliding groove 11. The connecting plate 7 is provided to enhance the stability of the telescopic rod body 4 during rotation and improve the overall stability of the device.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
