## Abstract

A portable and adjustable fastening mechanism is used to detachably fastening a mobile electronic device to an object. The fastening mechanism includes a gripping members located at end portions of a first support and symmetrically arranged about a geometric center of the first support. The gripping members can hold the electronic device and be fixed to an object in a way that the electronic device can be detached from the fastening mechanism through a single-hand operation. The gripping members include an unlocking component that unlocks the locked gripping members; a taking-out-channel opening component disengaging the unlocking component from the edges of the electronic device; and a restoring assembly storing restoring potential energy when the unlocking component is disengaged from the edges of the electronic device and releasing the restoring potential energy to apply a restoring force to the unlocking component when the gripping members are unlocked.

the mount (1) comprises first and second supports (101, 102) having a plate-like shape, wherein the first and second supports (101, 102) define first and second hollow chambers (103, 104) allowing mounting of the mobile electronic device onto the mount (1), wherein each of the first hollow chamber (103) of the first support (101) and a second hollow chamber (104) of the second support (102) has a first end surface (105) and a second end surface (106), each of the first hollow chamber (103) and second hollow chamber (104) comprising a bottom surface (107) and a lateral surface (108),
wherein the movable joint (2) is rotatably connected to the receiving portion (302) to form a spherical pair in which the receiving portion (302) comprises a hemispheric recess formed on the first clamp (3011) or the second clamp (3012) as a hollow chamber having an opening,
wherein the movable joint (2) extends in an axial direction of the movable joint (2) and has a first end portion (201) formed with the spherical surface to be fittingly rested in the receiving portion (302) of the base (3), and
wherein the receiving portion (302) comprising the hemispheric recess is provided with a positioning bump, wherein the movable joint (2) has its first end portion (201) formed with at least one positioning recess fittingly received by the receiving portion (302), wherein the positioning bump is inlaid in the positioning recess, so that the movable joint (2) is positioned with respect to the receiving portion (302).

### Claim 2

A portable and adjustable fastening mechanism, configured to detachably fasten a mobile electronic device to an object, wherein:
the fastening mechanism comprises: a mount (1), a movable joint (2) and a base (3), the movable joint (2) connecting the mount (1) with the base (3), the base (3) being configured to fix the mount (1) to a specified site, the fastening mechanism being characterized such that,
the base (3) comprises a fastening portion (301) configured to allow engagement with a desired object, and a receiving portion (302) configured to receive the movable joint (2), the fastening portion (301) comprising a first clamp (3011) and a second clamp (3012), wherein the first clamp (3011) and the second clamp (3012) are movably connected to each other so that the first clamp (3011) and the second clamp (3012) jointly form a circular component able to pivot with respect to each other and provide locking mechanism (3013) ensuring engagement between the fastening portion (301) and the object; and
