A door closer has a fixing set (10), a bidirectional set (20), and an extending set (30). The fixing set (10) has an elongated tube (11) with two opposite sidewalls (111) and an opening (113). The bidirectional set (20) is connected to the fixing set (10), is mounted in the elongated tube (11) and has a connecting board (21) formed on the bidirectional set (20) and extending out of the opening (113). The extending set (30) is connected to the bidirectional set (20) and has a guiding track (31), an extending arm (32), a locking board (33), and a connecting panel (34). The extending arm (32) is mounted in the guiding track (31). The locking board (33) engages the guiding track (31) and is connected to the extending arm (32) to adjust the extending set (30). The connecting panel (34) is connected to the extending arm (32). |
