Portable and adjustable fastening mechanism

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
• 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) has an end portion (202) movably connected to the mount (1),
• wherein the end portion (202) is provided with a retaining plate (203) in the form of a round disk, the retaining plate (203) being soldered to or integrally formed with the movable joint (2),
• wherein the retaining plate (203) supports a compression spring (204) having an axial direction perpendicular to a radial direction of the retaining plate (203) and has at least two openings (205) passing therethrough in a peripheral direction, each opening extending in the radial direction of the retaining plate (203) to a rim of the retaining plate (203),
• wherein the bottom surface of the first hollow chamber (103) or the bottom surface of the second hollow chamber (104) is formed with a retaining socket (109) shaped to match the retaining plate (203),
• wherein the retaining socket (109) has a third hollow chamber (110) that is columnar and open at one end, has a depth perpendicular to the bottom surface (107) that is greater than the thickness of a retaining plate (203), has a lower, second open end (304) shaped according to the retaining plate (203) and an upper, open first end (303), and has an opposite end portion closed so as to define the first end (303) of the retaining socket (109), and
• wherein the second open end (304) is shaped to match the retaining plate (203) so that the retaining plate (203) can be placed into the third hollow chamber (110) through the open end surface of the retaining socket (109).
