Description

Technical Field

[0001] The utility model relates to the field of mobile phone clamps, in particular to a foldable mobile phone bracket. Background Art

[0002] On March 9, 2021, the applicant applied for a mobile phone clamp named "A mobile phone clamp for shooting and live broadcasting", with patent number 202120526923.6. The mobile phone clamp includes two support frames and a mobile phone clamp body located on the support frames, so that it can be used by unfolding or folding it to form different usage states. However, there is a defect in this technical solution, that is, the support frame plates are fixed to the base by friction. In the fitted state, if one of the support frame plates receives a certain external force, it will automatically open, resulting in poor stability in the fitted state, which is inconvenient to store and use. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide a foldable mobile phone holder which can be fixed in a fitted state to avoid unfolding.

[0012] As a further improvement of the above technical solution, a mounting boss is provided upwardly on the top of the base, and the first connecting arm and the second connecting arm are both pivotally connected to the mounting boss.

[0013] As a further improvement of the above technical solution, the mounting boss is provided with two axial holes running through the front and back, and the middle of the bottom of the first connecting arm and the second connecting arm are provided with air avoidance holes upward to form a first support leg and a second support leg located on both sides of the air avoidance holes, and the first support leg and the second support leg are respectively located on both sides of the mounting boss, and a rotating shaft inserted in the axial hole is provided between the first support leg and the second support leg.

[0014] As a further improvement of the above technical solution, both the first connecting arm and the second connecting arm are provided with a topological hole located above the air avoidance hole.

[0016] As a further improvement of the above technical solution, the adjustment slot is a vertical structure, the top of the adjustment slot is located at the edge of the bottom of the topological hole, and the bottom of the adjustment slot is located at the top edge of the air avoidance hole.

[0017] As a further improvement of the above technical solution, a positioning surface is provided on the upper surface of the base, and abutment surfaces are provided on the first connecting arm and the second connecting arm. When the first connecting arm or the second connecting arm swings to a folded state, the abutment surface abuts against the positioning surface.

[0018] As a further improvement of the above technical solution, a magnet and a magnetic part are respectively provided on the surfaces of the first connecting arm and the second connecting arm facing each other, and in the folded state, the magnet and the magnetic part are magnetically attracted.

In the folded state, the locking protrusion can swing in the first arc-shaped swing groove and the second arc-shaped swing groove. When the locking protrusion swings into the second arc-shaped swing groove, since the second arc-shaped swing groove is arc-shaped, it has a height difference in the height direction. Therefore, at this time, the first connecting arm and the second connecting arm are fixed by the swing connecting rod and the locking protrusion, and the first connecting arm and the second connecting arm cannot be separated, so that the stability is better when in use or stored.
