The purpose of this creation and its structural and functional advantages will be explained in accordance with the structure shown in the following figure, in conjunction with specific examples, so that the review committee can have a deeper and more specific understanding of the creation.

Referring to the first figure and the second figure, the locomotive headlight adjustment mechanism of the present invention comprises a lamp holder (1), a locking seat (2) and at least two limit locking ears (3). The lamp holder (1) comprises a lamp cover (11) and a frame (12); the lamp cover (11) is provided with an accommodating space for arranging at least one lighting component, and the lampshade (11) is provided with a venting pipe (13) to exclude The lamp cover (11) is extended by a fixing bracket (14), and the fixing bracket (14) is fixed to the bottom side of the lamp cover (11) by a plurality of first bolts (11), and the fog cover (11) is extended by a temperature difference. The fixing bracket (14) is provided with a card slot (142); the frame (12) is framed on the lamp cover (11), and is provided with at least two locking ear fixing frames (15), and the locking ear fixing frame (15) has a A limit block (151) and a perforation (152).

The locking seat (2) comprises a bearing seat (21) and an adjusting component (22), the fixing bracket (14) bears against the bearing seat (21), and the adjusting component (22), for example a second The bolts are sequentially threaded through the bearing seat (21), a gasket (23), and the fixing bracket (14), and then locked by a suspension nut (24), by which the suspension nut (24) can be The elastic piece (241) is clamped on the card slot (142) of the fixing bracket (14); the bearing seat (21) extends with two wing pieces (211), and each of the air pieces (211) has at least one first lock. A hole (212) for fixing the bearing seat (21) to the locomotive frame body.

The limit lock ear (3) is pivotally connected to the lock ear fixing frame (15) by a pivoting member (31), so the lock ear fixing frame (15) can swing relative to the limit lock ear (3), thereby driving the light The seat (1), the pivoting member (31) may be a third bolt, which is passed through the through hole (311) of the limit lock ear (3) and the through hole (152) of the lock ear mount (15), and Pivot a nut (33) provided on the lock ear holder (15) In the lock ear fixing frame (15); in addition, the limit lock ear (3) has a concave limit portion (32) and a second lock hole (312), and the limit portion (32) is stuck in the limit position Block (151) to limit the swing angle of the socket (1), and the second lock hole (312) for locking the limit lock ear (3) to the frame body.

Referring to the third figure, the limiting portion (32) of the limiting lock ear (3) is engaged with the limiting block (151) of the locking ear fixing frame (15), and the limiting portion (32) is concave. The shape and the two clamping portions (321) are formed, and the two clamping portions (321) are respectively engaged on the upper and lower sides of the limiting block (151).
