When it is necessary to adjust the length of the second connecting arm 42 extending out of the first connecting arm 41, the pressing member 43 is pressed and the second reset member 45 is compressed so that the tooth portion 441 is separated from the rack portion 421. At this time, the second connecting arm 42 can be pushed and pulled to adjust the position of the second connecting arm 42 relative to the first connecting arm 41, and after the adjustment is completed, the pressing member 43 is released so that the second reset member 45 drives the tooth portion 441 to mesh with the corresponding rack portion 421 after adjustment, thereby completing the mutual limitation between the second connecting arm 42 and the first connecting arm 41 after adjustment.

[0085] Furthermore, one end of the second connecting arm 42 extending from the first connecting arm 41 is also connected to a universal ball head 46, and the universal ball head 46 is used to connect to an electronic product. Furthermore, the receiving slot 114 can also receive the universal ball head 46.

[0086] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein are interpreted accordingly.

[0087] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0088] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
