Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone brackets, in particular to a liftable magnetic mobile phone bracket. Background Art

[0002] The mobile phone holder basically fixes the mobile phone through two methods: clamping and magnetism. Compared with the clamping type mobile phone holder, the magnetic type mobile phone holder is more convenient in taking and placing the mobile phone. At the same time, the mobile phone can also be rotated 360 degrees to position. Therefore, the magnetic type mobile phone holder is more convenient and flexible to use.

[0003] Most of the existing magnetic mobile phone holders adopt a foldable design, which is convenient for storage and can also adjust the placement angle of the mobile phone. The magnetic mobile phone holder with a foldable structure generally includes a base, a magnetic seat, and support arms that are rotatably connected to the base and the magnetic seat at both ends; however, the length of the support arm of the foldable magnetic mobile phone holder cannot be adjusted, which will result in the inability to stably adjust the placement height of the mobile phone, resulting in insufficient use. In addition, the base generally limits the support arm through a limit point to limit the maximum expansion angle of the support arm. The limit point is easily worn during use and loses its limiting effect on the support arm. For this reason, we propose a liftable magnetic mobile phone holder. Utility Model Content
