first, the electronic product is fixed to the connecting portion 41 of the second rod 40 through the bracket, so as to realize the fixed connection between the electronic product and the bracket base 100. The stand base 200 is then adjusted according to a desired display angle of the electronic product, and during the adjustment, a rotational force may be applied to the base 20, so that the base 20 and the fixing base 10 horizontally rotate. The pushing pieces 52 on the rotation stopping structures 50 on both sides of the first rod 30 near one end of the base 20 can be pressed simultaneously, so that the two rotation stopping assemblies 53 inserted into the first connecting piece 31 and the second connecting piece 32 are pushed out from the through hole 51, and the relative rotation between the base 20 and the first rod 30 can be realized. The pushing pieces 52 on the rotation stopping structures 50 on both sides of the first rod 30 near one end of the second rod 20 can be pressed simultaneously, so that the rotation stopping assembly 53 inserted into the first connecting piece 31 and the second connecting piece 32 is pushed out from the through hole 51, and the relative rotation between the second rod 40 and the first rod 30 can be realized. Pressing both the rotation stopping structures 50 simultaneously can facilitate the operation, but is more stable and effective for the controllability of the first stick 30. The fixed angle and the fixed position of the electronic product on the connecting portion 41 of the second rod 40 can be adjusted by adjusting three different positions on the bracket base 100, so that the display angle of the user can be satisfied.

The utility model provides a collapsible between the first body of rod 30 and the second body of rod 40 that have in support base 100(200), convenient storage, through setting up at the both ends of the first body of rod 30 and spline structure 50, not only can adjust the relative rotation angle between the first body of rod 30 and the base 20 and between the first body of rod 30 and the second body of rod 40 effectively, can also be used for between the first body of rod 30 and the base 20 and the first body of rod 30 and the second body of rod 40 between fixed to realize support base 100(200) the stability of support when fixed connection electronic product.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
