The first support 11 is used for connecting a first device, which may be, for example, a camera, a video camera or the like. The second support 12 is rotatably coupled to the first support 11 by a rotation shaft assembly 15 so that the second support 12 can be folded and unfolded with respect to the first support 11 and maintained in an unfolded position. In this way, on the one hand, it is convenient to support the stand 1 on a device such as a display, so that the first device can obtain a better shooting angle, which is advantageous for expanding the use scene of the first device.

The third flexible layer 123 is disposed on the first surface and extends to the fifth surface, and an avoidance hole for avoiding the threaded hole is disposed on the third flexible layer 123 on the first surface.

By providing the second flexible layer 115 and the third flexible layer 123, on the one hand, friction force can be increased, and the relative sliding between the bracket 1 and the second device such as a display is avoided, so that the reliability of the bracket 1 in use is effectively improved. On the other hand, the second device and the bracket 1 can be protected, and the second device and the bracket 1 are prevented from being damaged by scratch and the like, so that the reliability of the bracket 1 is further improved.

Other embodiments of the application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the application following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice within the art to which the application pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the application being indicated by the following claims.

It is to be understood that the application is not limited to the precise arrangements and instrumentalities shown in the drawings, which have been described above, and that various modifications and changes may be effected without departing from the scope thereof. The scope of the application is limited only by the appended claims.
