By setting the hook, the vacuum lifting component and the suction cup, the overall structure is more reasonable and simple, cost is saved, and the suction force is stronger, which can adapt to different adsorption scenarios. In this embodiment, the fixing part 1 41 and the hook 1 are connected by the fixing component 4, and the fixing part 2 and the vacuum lifting component 2 are connected, so that the entire vacuum suction cup connection is more reasonable and tight. At the same time, the hook 1 is set to be hook-shaped. Of course, the hook is not limited to the hook shape, and can also be a bar shape, a ring shape, a semi-circular ring shape, etc. The shape of the hook can be set according to different needs, as long as its function is to hang the object.

[0040] Specifically, Figure 1 As shown, the fixing assembly 4 includes a fixing part 1 41 and a fixing part 2 42 which are fixedly connected to each other or integrally formed, and the fixing part 1 41 and the fixing part 2 42 are both provided with threads, the hook 1 and the fixing part 1 41 are detachably connected through threads, and the vacuum lifting assembly 2 and the fixing part 2 42 are detachably connected through threads. In this example, by providing threads on the fixing part 1 41 and the fixing part 2 42, the hook 1 and the vacuum lifting assembly 2 are detachably connected to the fixing assembly 4, so that the connection between the structures is more stable and tight. At the same time, according to actual needs, the pitch and the thread can be designed to be the values ​​that best meet the needs of the suction cup lifting, which can not only effectively improve various values ​​to achieve the purpose of adjusting the vacuum degree, but also, of course, is not limited to the pitch and thread lifting height settings, nor is it limited to the forms of internal threads and external threads or coarse threads and fine threads, as long as it can meet the working principle of the vacuum suction cup.

When the vacuum suction cup rotates, when it rotates to a certain degree and the vacuum degree reaches a certain degree, the limiting groove 223 and the track rod 213 will cooperate to make a click sound, that is, by setting the limiting groove and the track rod, the vacuum lifting component is limited during the rotation process, and will not twist significantly without effect. On the other hand, the vacuum lifting component has a certain guidance during the rotation process, and the suction cup is gradually lifted upward, which is simple, convenient, and more ergonomic to operate. Of course, the limiting grooves and track rods are not limited to the number, as long as they can achieve the above-mentioned purpose and function.

In this embodiment, the shell 5 is made of metal. Of course, the shell 5 is not limited to metal, and can also be made of plastic, rubber and other materials.

[0046] Specifically, a lifting piece 31 is provided on the suction cup 3 for opening the suction cup by external force, and the lifting piece 31 is fixedly connected or integrally formed with the suction cup 3. By providing the lifting piece, the suction cup is more convenient to disassemble. If the rotating lifting assembly is damaged, the suction cup can be opened by external force as a secondary guarantee. In this example, a lifting piece is provided, but of course, it can also be not provided.

[0047] Specifically, the material of the suction cup 3 is PVC. Of course, the material of the suction cup 3 is not limited to PVC, and can also be TPU, rubber and other materials.

[0048] Specifically, the hook 1 is in the shape of a bar, a ring, a semi-circular ring or a hook. The shape of the hook can be set according to different needs, as long as its function is to hang items, and is not limited to shapes such as a bar, a ring, a semi-circular ring or a hook.

[0049] Working principle: The user will press the vacuum lifting component, that is, act on the lifting pressure plate, that is, by pressing the lifting pressure plate, the suction cup and the relevant plane are tightly adsorbed. When encountering different types of planes, the vacuum lifting component can be used, that is, by rotating the rotating cover body, the lifting pressure plate can be lifted upward, and then the suction cup can be lifted upward, that is, the suction cup can be easily lifted upward to form a vacuum, so that the suction cup is adsorbed tighter, otherwise the rotating cover body will be rotated in the opposite direction to release the suction cup.

[0050] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
