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 utility model, 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 utility model 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, as shown in fig. 8, the deformation zone 22 in embodiments of the present utility model 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 utility model.

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 utility model 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 utility model, 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 utility model, 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 utility model, 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 some embodiments, as shown in FIG. 5, the thickness L2 of the deformation zone 22 decreases gradually from one end connected to the bearing zone 230 to the other end. According to the embodiment of the utility model, the thickness of the deformation zone 22 is reduced from one end to the other end, so that the stability of the suction cup and the tabletop adsorption can be maintained, and the difficulty of a user in picking up the suction cup from the tabletop can be reduced.

In some embodiments, as shown in fig. 9-11, the deformation zone 22 is provided in plurality, and each deformation zone 22 is provided with a groove 23 at its periphery. It should be noted that, in the implementation of the present utility model, the number of the deformation zones 22 is not limited, for example, the deformation zones 22 may be 1, 2, 3, 4, 5, 6, etc., and no matter how many deformation zones 22 are provided, the outer sides of the deformation zones 22 are provided with corresponding grooves 23. The embodiment of the present utility model is not limited to the form of arranging the deformation zones 22, for example, as shown in fig. 9, the deformation zones 22 may be arranged in a concentric space manner, or as shown in fig. 10, the deformation zones 22 may be arranged in a matrix manner. According to the embodiment of the utility model, the deformation areas are arranged in a plurality, so that the stability between the sucker and the surface to be adsorbed is improved, and the difficulty in disassembling the sucker and the surface to be adsorbed is reduced, thereby being beneficial to improving the convenience of use of users.

In some embodiments, the plurality of protrusions are provided with at least one specification setting parameter, including hardness, thickness, length, and an angle between the deformation zone and the flattening zone.
