The base 201 is detachably connected to the mobile phone case 100 through the annular groove 203 and the annular boss 207.

[0038] See also Figure 8-Figure 11 The damping adjustment component 300 includes a sliding groove 301 opened on the surface of the mobile phone shell 100, a slider 302 is slidably connected inside the sliding groove 301, a push plate 303 is fixedly installed on the surface of the slider 302, and a push plate groove opposite to the push plate 303 is opened on the outer surface of the mobile phone shell 100.

[0040] See also Figure 8-Figure 11 The overall length of the first spring needle 305 is greater than the overall length of the second spring needle 304. The second spring needle 304 has the same internal structure as the first spring needle 305, and both are composed of a sleeve, a needle rod and a spring, wherein the spring is installed inside the sleeve, and the needle rod is inserted into the open end of the sleeve. The spring provides elastic force for the needle rod. The head end of the needle rod of the second spring needle 304 is fixedly installed with a semicircular clamp corresponding to the corrugated teeth 307, and the head end of the needle rod of the first spring needle 305 is fixedly installed with a mounting platform corresponding to the arc surface locking platform 306.

[0041] Working principle: When in use, the finger ring buckle 205 is lifted up to form a vertical relationship with the base 201, and the finger ring buckle 205 can be used to support the mobile phone;

[0042] The push plate 303 is used to move the slider 302 backward, and the two second spring needles 304 are moved backward along the corrugated teeth 307. At the same time, the first spring needle 305 and the arc locking platform 306 are also moved backward. The arc locking platform 306 is no longer in contact with the arc tooth groove 204 on the outside of the base 201, and the base 201 is unlocked, so that the finger ring buckle 205 can be rotated, and then the position of the finger ring buckle 205 is adjusted.

[0043] On the contrary, the slider 302 is moved forward by the push plate 303, and the two second spring pins 304 move to the maximum travel distance, and the first spring pin 305 pushes the arc surface locking platform 306 to insert into the arc surface tooth groove 204 outside the base 201, so that the base 201 can be locked, and then the finger ring buckle 205 can be fixed;

[0044] At the same time, when the base 201 is locked, the finger ring buckle 205 is rotated, and the arcuate tooth groove 204 on the outside of the base 201 will squeeze the arcuate locking platform 306, and the first spring pin 305 will also shrink. Continuously rotating the finger ring buckle 205 can achieve damped rotation of the base 201. At this time, a large resistance will be generated between the base 201 and the damping adjustment component 300 in the finger ring component 200. When used as a mobile phone holder, the base 201 is not easy to rotate.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
