Self-timer poles, which have been popular since last year, are similar to the camera's one-legged frame and can be stretched from tens of centimeters to one meter in length. As long as mobile phones, cameras and other photographic equipment are fixed on the self-recording rod, and connected through Bluetooth, self-timer with multi-angle and wide-angle can be realized. Because of its fun and practical use, the self-timer rod was also named one of the 25 best inventions in 2014 by Time magazine.
Speaking of the invention of self-timer rod, it was not only last year. As early as a magazine published in 1995, there is a concept design similar to self-timer pole in the chapter about "Useless Japanese Invention". It can be said that self-timer pole existed before the camera was available on the mobile phone.
