For example, in the use scene of mobile phone, whether it is watching video, video call or navigation, a stable mobile phone placing mode is needed. Traditional mobile phone supports are mostly fixed on various surfaces by mechanical clamping or pasting. Mechanical clamping mode may cause abrasion to mobile phone, and the applicable size of mobile phone is limited. Although pasting mode is relatively firm, it is often difficult to reuse, and may leave marks on the pasting surface when it is torn off.

[0003] As for the fixing device of sucking disc body type, that is, through the cooperation of sucking disc body and air pump, negative pressure is formed between mobile phone and support to achieve the purpose of adsorption. However, the monitoring ability of adsorption state is very limited in the adsorption process. This means that in actual use, users cannot know whether adsorption is in the best state. When adsorption is unstable, for example, due to the influence of factors such as slight vibration of the outside world, weight distribution change of the carried object itself or air pressure change of the use environment, the existing electric sucking disc cannot detect the change of adsorption state in time, nor can it automatically take corresponding measures to maintain or adjust the adsorption state. This may cause the electric sucking disc to fall off the support accidentally in the use process, which brings many inconveniences to users, and even causes damage to the carried articles.
