Previous technology Traditionally, the front light of a locomotive is installed on the front bezel of the locomotive, that is, a hole of a suitable size and shape must be made in the front bezel for the front light installation. Therefore, the precision with which the headlights engage with the holes is very important. If there is a gap between the two, it will not only damage the beauty of the overall architecture, but may also cause shaking or damage to the headlights due to poor fixing. Japanese Patent Laid-Open No. 2002-205 594 (hereinafter referred to as a conventional technique) discloses a locomotive headlight structure. Fig. 1 shows a front view of a front bezel of one of the conventional techniques. Fig. 2 shows a side cross-sectional view with a center line as a section line when a headlight 20, which is one of the conventional technologies, is installed on the front bezel 10. The upper part of the front baffle 10 has an opening 11 for engaging the mounting of the headlight 20. A siren 12 is installed below the opening 11. The headlight 20 includes a lamp housing 21, a light bulb 22, and a reflector 23. The lamp housing 21 has a curved surface, and is embedded in the opening 11 of the front bezel 10. The light bulb 22 is horizontally disposed at a central portion of the reflecting mirror 23 to provide a light source for locomotive lighting. The reflecting mirror 2 3 is composed of a reflecting body 2 3 1 and an extending portion 2 3 2. The reflecting body 2 31 is a bowl-like structure with an opening facing forward, and can reflect the light emitted by the bulb 22. The extension portion 232 extends backward from the top end of the reflective body 2 3 1 along the shape of the lamp housing 2 1, and the rear end thereof is -6-590934. The top. As mentioned above, the precision of the joint 11 between the opening 11 of the front baffle 10 and the lamp housing 21 is very important to avoid the gap between the two. Because the reflecting body 231 and the extension portion 232 are integrally formed, if the angle of the reflecting body 231 is to be adjusted, the angle of the extension portion 2 3 2 is bound to be changed. For example, if the elevation angle of the reflective body 2 31 is increased, the extension portion 2 3 2 will also move backward, and may collide with the lamp housing 21 or other components of the vehicle body. Therefore, in this design, a large space must be reserved to accommodate the displacement of the extension 2 3 2. In addition, the front bezel 10 must be provided with another opening for the installation of the siren 12, which is more complicated to manufacture and will increase the manufacturing cost. [Technical Content] The main object of the present invention is to provide a locomotive headlight structure that is easy to join and has no openings to install a siren, which can reduce the complexity of manufacturing and further reduce the manufacturing cost. A secondary object of the present invention is to provide a locomotive headlight structure capable of adjusting the tilt and elevation angles of a reflector, and to avoid mutual interference of components provided therein. Another object of the present invention is to provide a large locomotive headlight structure, which can increase the lighting effect and the overall appearance. The locomotive headlight structure of the present invention includes a lamp holder, a lamp housing, a front baffle, a rear baffle, and a main reflector. The lamp housing can be directly connected with the rear baffle. In addition, the locomotive headlight structure may further include an upper trim plate, which is a separate entity from the main reflector, which is disposed above the main reflector and extends rearward along the shape of the lamp housing. The main reflector is fixed to the lamp holder, and includes a bowl-shaped curved surface 590934 (3) Gu surface surface first reflection surface, and a central portion of the first reflection surface includes a first opening for installation. One main light. Furthermore, the lower part of the main reflector may further include a second reflecting surface having an approximately L shape, and the second reflecting surface includes a second opening for installing a position light. A gap is naturally formed between the front fascia and the lamp housing, and is used as a siren for the locomotive to sound. The back of the main reflector is connected with at least two round-head screws at the same horizontal height and at least one screw with a different installation height, so that the main reflector can advance and retreat through the screws to drive the main reflector to the two The connection of the round head screw is the rotation of the rotation axis, so that the pitch and elevation angles can be adjusted. Because the main mirror and the upper trim plate are different individuals, when the pitch and elevation angles of the main mirror are adjusted, the adjustment is easy and does not affect the upper trim plate, so interference between components can be reduced. By designing a gap between the lamp housing and the front end of the front bezel, it is not necessary to open a siren hole in the front bezel, thereby reducing the manufacturing cost. Embodiment Fig. 3 shows a perspective view of a locomotive headlight structure 30 according to the present invention, which includes a front bezel 31, a lamp housing 32, and a lamp holder 33. The lamp housing 32 is rear-mounted on the front bezel 31, and a gap 38 is formed between the front end of the lamp housing 32 and the front bezel 31, and the rear end is connected to the lamp holder 33. The front lamp structure 30 of the locomotive of the present invention does not have the holes described in the conventional technology. In contrast, since the rear end of the lamp housing 32 is directly connected to the lamp holder 33, it can be designed. The area of the lamp housing 32 is elastically increased, thereby improving the overall appearance. FIG. 9 is a cross-sectional view taken along the line A-A in FIG. 3 and is a schematic view showing a joint structure of the lamp housing 32 and the rear baffle plate 41 590934 (4). The lamp housing 3 2 can be mounted on the rear baffle plate 41. As shown in the figure, the inlay 41 is embedded below the rear edge of the lamp housing 3 2 so that FIG. 4 is the side structure of the sectional view 30 of FIG. 3 along the section line 1 -1. The lamp housing 3 2 Tie the lamp holder to the right 3 3. A main reflecting mirror 34 is fixed to the first reflecting surface 341 and a substantially flat surface 342 of the bowl-shaped curved surface. Among the first reflecting surfaces 341, 35, the light produced by the main lamp 35 can be concentrated and brightened. A position light 37 is disposed on the second as an auxiliary light source. An upper decorative plate 36 is arranged along the lamp Qinsheng for decoration. A gap 3 8 is formed between the front baffle 3], which can be used as a rear part of it. The central part of the lamp holder 3 3 is engaged with a guard. The main lamp 3 5 and the lamp holder 3 3. FIG. 5 is a cross-sectional view taken along the line 2-2 in FIG. 4. It is embedded in the lamp holder 3 3. The main reflecting mirror 3 4 has a back 5 4, which is composed of a left and right round head screws 5 1 and-wires 5 3. Each of the round head screws 51 has a screw head 5 2 and can be rotated therein, and its threaded end mirror 3 4 is on the back. Each fixing buckle 5 2 uses the screw 5 3. As the two round head screws 51 are located on the main reflector 34, the angle adjustment of the two round head screws 51 can be adjusted. Frequencies The fixing of the rear baffle can be aesthetically pleasing. . The locomotive headlight structure extends above and is connected to the seat 3 3. A main lamp is inserted through a second reflecting central portion of an approximately L shape to project forward to increase the reflection surface 3 4 2 for t 3 2 The shape is extended backwards ^ and the front end of the lamp housing 3 2 • The cover 40 of the siren 39 is used to connect the two sides of the lamp housing 3 2 with a rotating structure-a fixed buckle 5 2 and a screw bag The covering buckle is fixed to the main reflection and fixed to the lamp holder 3 3. At the same horizontal height, the connection is 590934
