The non-slip pad increases friction between the clamping device and the phone, preventing the bracket from slipping and improving its stability.

[0125] There is a driven gear inside the housing, the driven gear cooperates with the right-angle rack rod, the right-angle rack rod is connected to the reset spring, a clamping device is provided on the outside of the right-angle rack rod, an anti-slip pad is provided inside the clamping device, an active part (i.e., a transmission shaft) is provided on the upper part of the driven gear, and an automatic clamping knob is provided above the active part.

[0126] The clamping device is connected to the right-angle rack rod with screws. The outer side of the clamping device is a smooth curved surface, and the inner side is provided with a groove for installing an anti-slip pad. The anti-slip pad is set at a certain angle to prevent the clamping device from slipping or falling off when clamping the mobile phone.

[0127] Furthermore, the lens holder includes a clip 39 , which is clamped on the mobile phone 5 , and the input end of the external lens 1 is connected to the clip 39 .

[0128] The setting of the clip is used to support the external lens, prevent the external lens from tilting due to unbalanced force, and improve the stability and reliability of the bracket.

[0129] The embodiment of the present invention provides a mobile phone external lens filter holder, which is a device that combines the mobile phone external lens and filter for simultaneous use. It can effectively achieve gradient and light reduction effects at long and close distances, wide angle, telephoto, distortion, telephoto, macro, fisheye and other functions, making the shooting effect better. This holder can be folded to reduce space and is easy to carry. The mobile phone external lens filter holder consists of three parts: Figure 3 and Figure 4 Shown is the upper part of a mounted filter. Figure 5 and Figure 6 Shown is the middle section of a hinge link and sliding parts. Figure 9 and Figure 10 The following figure shows the bottom part of the automatic clamping device for mobile phones. These three parts are only used to illustrate the overall structure and do not represent three separate structures. The specific steps include:

[0130] (1) Combination Figure 9 、 Figure 10 、 Figure 11 、 Figure 17 and Figure 18 , by rotating the automatic clamping knob (i.e. the second knob) to adjust, the automatic clamping knob and the active part (i.e. the rotating shaft or transmission shaft) are interconnected to drive the active part, and the active part drives the driven gear. The rotational motion of the driven gear is converted into the linear motion of the right-angle rack rod, so that the two clamping devices are opened. When the hand releases the automatic clamping knob, the reset spring returns to its original state due to elastic deformation, so that the clamping device automatically clamps the mobile phone.

[0131] (2) Combination Figure 9 、 Figure 10 and Figure 19 The up and down sliding knob (i.e., the third knob) is rotated to drive the rotating gear, and the rotational motion of the rotating gear is converted into the linear motion of the push plate, so that the push plate slides up and down in the shell.

[0132] (3) Combination Figure 5 、 Figure 6 and Figure 7 ,pass Figure 7 Rotate the knob (i.e., the first knob) in the opposite direction of the schematic diagram to relax the hinges of each link. The relaxed link can be swung to a suitable position for the external lens. Adjust the angular positions of the end link, middle link, and starting link, and turn the knobs in sequence to lock each hinge.

[0133] (4) Combination Figure 5 and Figure 6 , adjust the rotation position of the rotating ring according to the scale value on the fixed rotating disk, let the rotating ring drive the rotating support to rotate, combined with Figures 14 to 16A magnified view of the area shows that the rotating ring uses the cooperation between the balls and the pits to fix the rotation position during rotation, so that the filter rotates to the appropriate angle position.

[0134] (5) Combination Figure 12 and Figure 13 , Install the filter. When fixing the frame, insert the filter from the end with the larger opening of the non-slip rubber pad. Figures 14 to 16 As shown, during the insertion process, the two anti-slip rubber pads are fixed to the filter by the compression of the spring.

[0135] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
