In this embodiment, when the first support 20 is in the first support position, the first included angle between the first support 20 and the connection housing 10 is 0°˜180° or 180°˜270°. When the first support 20 is rotated about 180°, the connection housing 10 can be lifted through the first support 20. At this time, the first support 20 is similar to the mobile phone rope, which is very convenient to use; When not in use, the first support is in the first folded position to reduce the occupied space. When it needs to be used, the first support 20 can be rotated to the first supporting position by manual, electric or mechanical driving. The support 20 and the connection housing 10 form a first included angle relationship, and the connection housing 10 and the support surface form a certain included angle, so that the mobile terminal can be placed in an inclined or vertical manner, which is convenient for users to use or watch.
