Moreover, the helical conducting body230of each conducting part23eliminates problems of complex wires. A locating slot221is provided on a top end of each guiding rail22, the two conducting parts23are respectively located in the two locating slots221so that the two conducting parts23can be protected from external vibration, and thus the stability of electrical connection between the controlling component1and the sliding component3is improved. Preferably, in order to facilitate the mounting and locating of each conducting part23, the first connecting section231and the second connecting section232are both configured as fixed ends extending outwardly along opposite axial directions of the conducting body230. Preferably, each conducting part23is a spring wire.

Preferably, the fixing part324presses the second connecting section232to the rotation component30by means of such as, bolt or the like, in order to realize an electrical connection between the rotation controlling module329and the two conducting parts23. During operation of the electrically controlled sliding apparatus100, the two conducting parts23each have two ends respectively fixed on the controlling component1and the sliding component3. One conducting part23is configured to supply power to the sliding component3, and the other conducting part transmits signals between the controlling component1and the sliding component3under the control of the controlling component1.

The positioning part27facilitates to limit a movement of the conducting body230along its axial direction without shift. The positioning part27may be flexible (such as a straightened string or the like) or a rod arranged linearly and parallel to each guiding rail22.

The configuration of each conducting part23having the curled conducting body230solves problems of complex wires in traditional electrically controlled sliding apparatuses for photographic equipment, eliminates defects caused by poor contact of connecting wires or by a use for long time and signal delay because of wireless transmission, and further provides a constant and synchronous connection between the controlling component1and the sliding component3, so that a timely and accurate sports photography can be ensured. Moreover, the aesthetic of the electrically controlled sliding apparatus100is ensured and user experiences are largely improved. In particular, an infrared module14of the controlling component1is arranged facing towards one of the electric brush strips230in order to accurately sense operations of the sliding component3equipped with a camera.
