A carrier frame (100) includes a first tubular member (1), a second tubular member (2), a third tubular member (3) and a folding unit (4) including a linkage rod (43), a second rod (44) and a pivot frame (41) pivoted to the second tubular member (2). The linkage rod (43) is pivoted to the first tubular member (1) and pivoted to the pivot frame (41). The second rod (44) is pivoted to the third tubular member (3) and pivoted to the linkage rod (43) to make the second rod (44), the linkage rod (43) and the pivot frame (41) cooperatively form a linkage structure. The carrier frame (100) can be released and folded synchronously and has advantages that the carrier frame (100) is easy to fold, has a simple structure, and is convenient to operate.
