Detailed Description

The present embodiment is a mobile phone stand, which can be triggered by the weight of the mobile phone itself, and as shown in fig. 1 and 2, the mobile phone stand includes a stand body 100, a pair of clamping arms 200 symmetrically disposed at two sides of the stand body 100, and a supporting arm 300 disposed at the lower side of the stand body 100; also included is a clamping mechanism that clamps the pair of clamp arms 200 inwardly, which is triggered when there is downward pressure on the support arm 300. At present, the clamping mechanism generally comprises a pair of springs driving the two clamping arms 200 to slide inwards, and since the elastic force of the springs is continuous, the springs can continuously apply an inward clamping force to the two clamping arms 200, and cannot be loosened due to weightlessness of a clamped object such as a mobile phone and the like in a bumping process, and only an external force is applied to break the two clamping arms 200 to be loosened. At this time, if a mechanism is used to balance the elastic force of the spring, the mobile phone will be kept in a relaxed state, and if the mobile phone or other articles to be clamped are placed on the supporting arm 300 in the relaxed state, the supporting arm 300 senses gravity, and generates a trigger signal, so as to eliminate the mechanism of the elastic force of the balance spring, and the clamping arm 200 will clamp the clamped mobile phone again. The clamping mechanism may be composed of the clamping arms 200, the bracket body 100, the supporting arm 300, etc. and necessary springs, as in the present embodiment, or may be an electronic circuit, such as a sensor, which senses the weight of the object on the supporting arm 300 and generates a trigger signal to trigger a motor to drive the clamping arms 200 to clamp the object from both sides, or a button to generate a trigger signal to trigger the motor to release the clamping arms 200 if the object is to be removed. In summary, there are many prior art mechanisms for such continuous gripping of an article. In this embodiment, a clamping mechanism with a pure mechanism is provided, which is composed of a clamping arm 200, a bracket body 100, a supporting arm 300, and the like.
