In some embodiments, as shown in FIG. 5, the deformation zone 22 has a thickness L2 of 0.2mm or more and 0.6mm or less. According to the embodiment of the invention, the thickness L2 of the deformation zone 22 is set within a certain range, so that the deformation zone 22 is arranged on the flat zone 21 in a surrounding manner in a thin edge shape, which is beneficial to improving the flexibility of the deformation zone 22, facilitating the lamination of the deformation zone 22 on the surface to be adsorbed, and improving the adsorption stability of the deformation zone 22 and the surface to be adsorbed.

The included angle between the deformation zone 22 and the leveling zone 21 indicates the included angle between the deformation zone 22 and the leveling zone 21 in a natural state, and the deformation zone 22 is not affected by external force in the natural state, so that the deformation zone 22 extends naturally and cannot deform. Of course, it should be noted that, in the embodiment of the present invention, the angle between the deformation area 22 and the leveling area 21 may change with the increase of the number of times of use, and the angle θ defined in the embodiment of the present invention is the angle between the deformation area 22 and the leveling area 21 in the factory state, specifically, the angle between the extending direction of the deformation area 22 and the extending direction of the bottom surface of the leveling area 21.

In some embodiments, the angle between the deformation zone 22 and the flattened zone 21 may be set to different magnitudes. The size of the included angle can be set according to the scene of the specific practical sucker application.

In some embodiments, as shown in fig. 8, the deformation zone 22 in embodiments of the present invention may be configured as one or more of a circular ring, a square ring, or a diamond ring. In the embodiment shown in fig. 8, the deformation area 22 is configured as a square ring, and the shape of the deformation area 22 can be adaptively set according to the shape and structure of the bottom of the support frame, so as to improve the stability of the suction cup on the installation of the support frame. For example, in the case where the bottom of the support frame is provided in a circular shape, the deformation zone 22 may be provided in a circular shape; in the case where the bottom of the support frame is provided with a triangle shape, the deformation zone 22 may be provided with a triangle ring shape, and the shape of the deformation zone 22 is not limited in the embodiment of the present invention.

In some embodiments, as shown in fig. 8, the deformation zone 22 has a first extension 224 disposed opposite in the front-rear direction and a second extension 225 disposed opposite in the left-right direction, the first extension 224 and the second extension 225 being connected in a ring shape. The front-back-left-right direction in the embodiment of the present invention is only a direction of the relative position on the suction cup, and does not represent the front-back-left-right direction with respect to other reference objects in the absolute coordinate system. The deformation area 22 has an annular structure, and two first extending portions 224 are disposed opposite to each other in the front-rear direction, two second extending portions 225 are disposed opposite to each other in the left-right direction, and the first extending portions 224 and the second extending portions 225 are sequentially connected to form a closed loop deformation area 22.

In some embodiments, as shown in fig. 8, the setting parameters of the first extension 224 are greater than the setting parameters of the second extension 225, wherein the setting parameters include hardness, thickness, length, and angle with the flat area. It should be noted that, in the embodiment of the present invention, the set parameters represent the structural parameters and the material parameters of the deformation region. The hardness of the first extension portion 224 is greater than that of the second extension portion 225, which means that the elasticity of the first extension portion 224 is smaller than that of the second extension portion 225, so that there is a difference in elasticity between the first extension portion 224 in the front-rear direction and the second extension portion 225 in the left-right direction of the suction cup, so that the suction forces in the two directions are different, and in the process of detaching the suction cup adsorbed on the surface from the surface, the user can apply less external force to the suction cup in the front-rear direction due to the different suction forces in the two directions, so that detachment of the suction cup can be achieved. The thickness of the first extension portion 224 is greater than that of the second extension portion 225, and the thinner the thickness is, the stronger the deformability of the suction cup is, so the second extension portion 225 is set to be thinner than the first extension portion 224, and a user applies a smaller external force in the front-rear direction, so that the first extension portion 224 is separated from the tabletop relatively, and the whole suction cup can be detached. The greater the length is, the greater the suction force is, so that the lengths of the first extension part and the second extension part are not consistent, and the second extension part is separated from the table top by a small acting force in the left-right direction, so that the sucker is detached. The included angles between the sucker and the leveling area can be different, and the suction force corresponding to the different included angles is also different. It should be appreciated that in the prior art, conventional suction cups are non-directional, and that when a user desires to peel the suction cup off the suction surface, the suction force of the conventional suction cup is relatively uniform in each direction. Therefore, the user cannot easily peel the suction cup from the suction surface, for example, the user may shake the suction cup in different directions with disorder and applying a large external force, so that the suction cup can be peeled, and at this time, the user does a lot of idle work and easily shakes the product attached to the suction cup. If the product attached to the sucker is a mobile power supply, the electronic components in the mobile power supply are in poor contact due to the strong shaking of a user.

It is expected that the conventional suction cup needs to be peeled off from the suction surface and re-sucked when the user needs to adjust the suction cup angle, and there may be a case that the user needs to repeatedly peel off and suck the suction to adjust to the angle satisfactory to the user a plurality of times, which causes a great inconvenience. In the chuck of the present invention, when the setting parameters of the first extension 224 of the chuck are greater than the setting parameters of the second extension 225, the setting parameters include hardness, thickness, length and included angle with the flat area. It can be presumed that the suction force of the first extension portion 224 and the second extension portion 225 is not uniform, and the suction force of the first extension portion 224 and the second extension portion 225 is not uniform, so that the rotation of the suction cup on the suction surface is realizable, and when the suction cup angle is adjusted, a user does not need to peel the suction cup off the suction surface and readjust the suction cup, but can directly realize the rotation of the suction cup on the suction surface through the suction angle, which is more convenient and faster than the traditional suction cup, and is linear angle adjustment.

According to the embodiment of the invention, the setting parameters of the first extending part arranged in the front-back direction and the setting parameters of the second extending part arranged opposite to the first extending part in the left-right direction are set differently, so that the suction force acting on the tabletop by the first extending part and the second extending part is different, and the support is easy to take up by shaking in one direction and is easy to take up by shaking in the other direction.

In the case where the difference between the first air pressure difference between the inner side and the outer side of the first extension 224 and the second air pressure difference between the inner side and the outer side of the second extension is equal to 0, the first air pressure difference between the inner side and the outer side of the first extension is equal to the second air pressure difference between the inner side and the outer side of the second extension, and in the case where the difference between the first air pressure difference between the inner side and the outer side of the first extension 224 and the second air pressure difference between the inner side and the outer side of the second extension is greater than 0, it is indicated that the difference is an absolute value, that is, the embodiment of the present invention does not limit whether the first air pressure difference is greater than or less than the second air pressure difference.

The included angles between the sucker and the leveling area can be different, and the suction force corresponding to the different included angles is also different.
