The surface of the fixed plate 8 in contact with the spring sheet 15 is provided with a plurality of grooves 804. When the rotating plate 5 rotates relative to the housing 1, the spring sheet 15 switches from one groove 804 to another groove 804, thereby generating a sense of stuck and / or a sound of clicking. During the rotation of the rotating plate 5 relative to the housing 1, the spring sheet 5 moves relative to the fixed plate 8, thereby preventing the steel ball 10 from rotating and causing the spring 9 to deform.

[0036] In some embodiments, the second end 103 has a shaft portion 106, and the shaft portion 106 is cylindrical. The turntable 5 is provided with a first through hole 501, and the first through hole 501 is a circular hole adapted to the shaft portion 106.

The fixing disk 8 is provided with a second through hole 801, and the second through hole 801 is connected to the fixing portion 107, so as to realize the connection between the fixing disk 8 and the housing 1. Since the fixing portion 107 is non-cylindrical, when the turntable 5 rotates relative to the housing 1, the fixing disk 8 does not rotate relative to the housing 1. In some embodiments, the fixing portion 107 is a quadrangular prism, and the second through hole 801 is a square hole adapted to the quadrangular prism.

[0039] In some embodiments, the fixing disk 8 includes a cover plate portion 802 and an annular portion 803 extending toward the first end 102. The cover plate portion 802 is provided with the second through hole 801; the turntable 5 is provided with a first annular groove 503, and the annular portion 803 is disposed in the first annular groove 503 to realize the abutment of the elastic piece 15 against the annular portion 803.

[0041] In some embodiments, the connection portion between the first portion 1501 and the second portion 1502 is an arc shape matching the steel ball 10, so that the steel ball 10 can better abut against the elastic piece 15.

[0042] In some embodiments, the first receiving groove 501 includes a first section 5011, a second section 5012, and a third section 5013.

The first circuit board 4 and the vacuum pump 3 are disposed within the first accommodation cavity 101, and the first circuit board 4 is electrically connected to the vacuum pump 3. The air extraction port of the vacuum pump 3 is communicated with the suction cup 2. When the suction cup 2 adsorbs on a mobile phone or a desktop, the vacuum pump 3 can extract the air inside the suction cup 2 to form a vacuum inside the suction cup 2, so that the suction cup 2 stably adsorbs on the mobile phone or the wall surface. In some embodiments, the first circuit board 4 is further provided with a USB charging port 403, and the USB charging port 403 is electrically connected to the first circuit board 4.

The present application adopts the design that the positive conductive head 401 slides on the first annular conductive track 601 and the negative conductive head 402 slides on the second annular conductive track 602. When the turntable 5 rotates relative to the housing 1 to adjust the viewing angle of the mobile phone, there is no situation where the bracket cannot be used due to the twisting and damage of the wire connecting the first circuit board 4 and the second circuit board 6, greatly extending the service life of the bracket. In some embodiments, the positive conductive head 401 and the negative conductive head 402 are made of PIN pins.

[0045] In some embodiments, the housing 1 includes an upper housing 104 and a lower housing 105.
