Background The mobile phone support can be arranged on the back of the mobile phone or the mobile phone shell so as to support the mobile phone and obliquely place the mobile phone on the desktop, and in the related art, the mobile phone support comprises two relatively rotatable frame bodies, wherein one frame body is used for being connected with the mobile phone or the mobile phone shell, and the other frame body is used for being supported on the desktop, and when the two frame bodies relatively rotate, the frame bodies can be folded or unfolded so as to be convenient to store and use. The through holes are formed in the two frame bodies, the rotating shafts in interference fit with the through holes are arranged in the through holes in a penetrating manner, so that the two frame bodies can rotate relatively and have a certain damping force, the two frame bodies can be kept at the current rotation angle, and the damping force is unchanged in the rotation process of the two frame bodies due to the fact that the sections of the through holes and the sections of the rotating shafts are circular. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the first aspect of the present utility model proposes a rotating shaft with better hand feel. The utility model also provides a mobile phone support. According to the embodiment of the utility model, the rotating shaft comprises a mandrel, a first rotating piece and a second rotating piece, wherein the first rotating piece is provided with a through hole, the mandrel penetrates through the through hole and is in interference fit with the hole wall of the through hole, a first end and a second end are arranged on the first rotating piece along the circumferential direction of the mandrel, the first rotating piece can rotate relative to the mandrel so that the first end and the second end can be mutually close to or far away from each other to adjust the diameter of the through hole, a guide surface is arranged on the first rotating piece, a sliding groove extending along the radial direction of the mandrel is arranged on the second rotating piece, one end of the mandrel can be slidably arranged in the sliding groove, and an abutting part is arranged at one end, close to the first rotating piece, of the first rotating piece, wherein when the first rotating piece rotates relative to the mandrel, the abutting part moves along the guide surface and pushes the first rotating piece so that the first rotating piece drives the mandrel to slide along the sliding groove. According to the rotating shaft provided by the embodiment of the utility model, the rotating shaft has at least the following technical effects: In the rotating shaft, the mandrel is arranged in the through hole of the first rotating member in a penetrating manner and is in interference fit with the hole wall of the through hole, the first rotating member is driven to rotate forwards relative to the mandrel, so that when the first end and the second end of the first rotating member, which are arranged along the circumferential direction of the mandrel, are close to each other, the aperture of the through hole is reduced, damping between the first rotating member and the mandrel is increased, and when the first rotating member is driven to rotate reversely relative to the mandrel, the aperture of the through hole is increased, and damping between the first rotating member and the mandrel is reduced. When the mobile phone support needs to be opened, the first rotating piece reversely rotates relative to the mandrel, the first end of the first rotating piece is far away from the second end, the damping between the first rotating piece and the mandrel is reduced, so that the force applied by the mobile phone support when the mobile phone support is opened is smaller, and further, the mobile phone support has a light switching feel in the use process by adopting the rotating shaft of the application, so that the use feel of the mobile phone support adopting the rotating shaft of the application is improved.
