Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims, under 35 U.S.C. § 119(a), the benefit of Korean Patent Application No. 10-2022-0070437, filed on Jun. 10, 2022, the entire contents of which are incorporated herein by reference. BACKGROUND Technical Field The present disclosure relates to a holder device for a power supply rail. More particularly, it relates to a holder device for a power supply rail configured to be slidably movable along a power supply rail and fixed in the power supply rail in a state in which a mobile device is mounted on the holder device. Background In general, a lighting fixture is mainly installed on the ceiling and is fixedly installed at a determined location at the time of initial construction of the lighting fixture in order to equally provide a light source to the indoor space. However, since this lighting fixture is fixedly installed on the ceiling, it is difficult to move and rearrange the same depending on personal preference or the like. Accordingly, when the lighting fixture fixedly installed thereon is moved and rearranged, complicated and dangerous work such as wire arrangement construction is required to be performed by professional personnel. To this end, in the case of a place in which a lighting fixture is required to be moved frequently, a power supply rail may be used to facilitate movement of the lighting fixture. Further, various electronic devices such as a fan in addition to the lighting fixture may be detachably installed on the power supply rail, and the power supply rail may also be mounted on a place such as a wall surface as well as a ceiling. Meanwhile, in recent years, the use of a liquid crystal monitor, a terminal, and the like configured to enable a user to watch a TV broadcast, a stored image, and navigation inside a vehicle has increased. Accordingly, the use of a holder configured to fix such a mobile device also has increased. However, in the case of such a holder, since the holder is mounted on a vehicle air outlet and fixed thereto, damage to the air outlet may occur due to the weight of a mobile device mounted on the holder. Additionally, when a user wants to move the location of the mobile device, the holder is required to be removed from the air outlet and re-mounted at a desired location, which may cause inconvenience in use. In addition, in the state in which a mobile device is mounted on a holder, a power line is required to be separately connected to the mobile device to recharge the mobile device, which may spoil the aesthetics of the interior of the vehicle and may also cause a user to be exposed to the risk of electric shock. Therefore, it is important not only to enable a holder having a mobile device mounted thereon to easily move and to be easily mounted in the vehicle, but also not to expose a power line to the outside, thereby previously preventing problems related to the aesthetics of the interior of the vehicle and safety of a user. The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention, and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art. SUMMARY OF THE DISCLOSURE The present invention has been made in an effort to solve the above-described problems associated with the prior art, and it is an object of the present invention to provide a holder device for a power supply rail, the holder device including a main body part inserted into a power supply rail mounted in the vehicle interior and configured to be slidably movable. A sliding movement position of the main body part in the power supply rail is fixed through the rotation of a head part, and the main body part is additionally fixed in the power supply rail through a fixing member configured to selectively protrude from the main body part when the head part rotates, thereby making it possible to secure rigidity in the fixed state of the movement position of a mobile device mounted on the main body part. In one aspect, the present invention provides a holder device for a power supply rail, the holder device including a main body part positioned inside a power supply rail mounted in a vehicle interior and provided to be slidably movable in a rail direction, a head part rotatably coupled to the main body part, configured to fix a sliding movement position of the main body part inside the power supply rail, and formed to contact a pair of electrodes provided inside the power supply rail, and a fixing part formed to selectively protrude to an outside of the main body part when the head part rotates and provided to support an inner side of the power supply rail in a state in which the sliding movement position of the main body part is fixed. In a preferred embodiment, the main body part may include a stepped part formed to be locked in the power supply rail and configured to expose the head
