A strap-type mobile device holder configured to be fastened to a selected fixed position on a carrier after securing the mobile device, ensuring that the mobile device remains fastened onto the selected fixed position even when the carrier is in motion, the strap-type mobile device holder comprising:

• a holder body provided with a secure structure configured to secure the mobile device and comprising a first connecting portion and a second connecting portion positioned opposite each other;
• a first elastic strap comprising:
• a first solid section extending outward from the first connecting portion in a direction away from the second connecting portion and provided with a first buckle portion;
• and
• a first perforated section extending outward from the first solid section in a direction away from the holder body and provided with a first perforation positioned adjacent to the first solid section and at least one first buckle hole positioned away from the first solid section;
• and
• a second elastic strap comprises:
• a second solid section extending outward from the second connecting portion in a direction away from the first connecting portion and provided with a second buckle portion;
• and
• a second perforated section extending outward from the second solid section in a direction away from the holder body and provided with a second perforation positioned adjacent to the second solid section and at least one second buckle hole positioned away from the second solid section;
• wherein, when fastening the strap-type mobile device holder secured with the mobile device onto the selected fixed position on the carrier, the first elastic strap loops around the carrier and passes through the second perforation or the second elastic strap loops around the carrier and passes through the first perforation, such that the at least one first buckle hole engages with the second buckle portion and the at least one second buckle hole engages with the first buckle portion, thereby securing the strap-type mobile device holder onto the selected fixed position by a bidirectional buckle mechanism.
