Preferably, the connecting member 41 is engaged with the connecting portion 421 through the second avoiding hole 413 along a set direction, which is a rotation direction of the mobile phone clip 130 relative to the limiting portion, so as to prevent the connecting portion 421 from rotating when the mobile phone clip 130 rotates. Optionally, the second avoiding hole 413 is a waist-shaped hole, the shape of the connecting portion 421 is adapted to the second avoiding hole 413, and the connecting portion 421 is inserted into the second avoiding hole 413.

Since the bottom of the handset clip 130 (i.e., the bottom of the support bottom case 7b) abuts against the mounting portion 11, there is a frictional force therebetween, and the handset clip 130 is held stationary with respect to the mounting base 1 by this frictional force. Manually rotating the mobile phone clip 130, wherein the mobile phone clip 130 overcomes the friction force between the mobile phone clip and the mounting seat 1, and rotates to a corresponding angle relative to the mounting part 11 on the upper surface 121 of the mounting part 11; after releasing the hand, the phone clip 130 is maintained at the corresponding angle by the friction force between the phone clip and the mounting base 1.

When the mobile phone clip 130 is initially installed on the armrest 110, the second clamping portion 75 and the first clamping portion 72 are disposed at an interval from top to bottom, that is, the bottom end of the bottom shell 71 is matched and abutted against the positioning side 122 of the positioning portion 12, and the first clamping portion 72 and the second clamping portion 75 clamp the mobile phone 150 along the longitudinal direction of the mobile phone 150, which is mainly suitable for the user to vertically view the mobile phone 150. When the user wants to watch the mobile phone 150 with the landscape screen, the mobile phone clip 130 is manually rotated by 90 °, and at this time, the first clamping portion 72 and the second clamping portion 75 are spaced apart in the horizontal direction, so that the two can clamp the mobile phone 150 in the horizontal direction of the mobile phone 150. The mobile phone 150 is rectangular, the longitudinal direction is the length direction of the mobile phone 150, and the transverse direction is the width direction of the mobile phone 150. In addition, when the user uses a tablet, the mobile phone clip 130 may be rotated by 90 ° so that the first and second clipping portions 72 and 75 are spaced apart in the horizontal direction to clip the tablet.

Preferably, the positioning side surface 122 is an arc surface, and the bottom end surface of the supporting bottom case 7b is also an arc surface adapted to the positioning side surface 122, and a center of the arc surface coincides with a rotation axis of the mobile phone 150 support. When the mobile phone clip 130 is rotated from the initial state, the bottom end surface of the support bottom case 7b slides along the positioning side surface 122, thereby ensuring the smoothness of the rotation of the mobile phone clip 130.

Preferably, the connecting piece 41 and the mounting base 1 are of an integrated structure, the connecting piece 41 is not needed, and the machining efficiency is high.
