Description of the Invention: [Technical Field] The present invention relates to a positioning device, and more particularly to a positioning device for a backlight module. [Background] FIG. 1 is a conventional backlight module 1 including a frame 丨丨, a backlight unit 12 (for example, a diffusion plate, a reflection plate, a light guide plate, a light source, etc.) disposed in the frame 11 and two positioning positions. The two positioning members 13 are made of a plastic material, and each of the positioning members 13 is similar to a side frame bead for a liquid crystal display device disclosed in the Chinese Patent Publication No. 200523831, which is generally U-shaped and has a u-shaped strip-shaped body 130 and a plurality of engaging members 131 extending downward from the body 13 ,, and the frame π outer wall surface is also provided with a plurality of bumps 1U corresponding to the engaging members 131, two The positioning member 13 is positioned on the opposite sides of the frame 11 by the engagement of the engaging members 131 with the projections 1U of the frame n, and the backlight unit 12 is pressed by the positioning member 本体3. Located in the frame 丨1. Generally, the positioning member 13 of the plastic material is formed by injection molding, but because the outer shape thereof is elongated, not only the required material is used in a large amount, but also the size of the mold is not easy to be formed at one time. The manufacturing time is elongated, and since the positioning member 13 is engaged with the projections 111 of the frame n by the plurality of engaging members 131, the disassembly and assembly is also time consuming and labor-intensive. SUMMARY OF THE INVENTION An object of the present invention is to provide a positioning device that takes up both the amount of material and the same positioning effect. 5 1337283 Another object of the present invention is to provide a backlight module in which the positioning member is more material-saving. Therefore, the positioning device of the backlight module of the present invention is applicable to a backlight module. The backlight module includes a frame having a rectangular shape and a backlight disposed on the frame. The positioning device includes four interference portions and four positioning members. The four interference portions T: in the four corners of the frame, each of the interference portions includes a first interference member and a second interference member respectively located at adjacent frame edges of the corner of the frame; four fixed: the vertical member is used for positioning Each of the four corners of the frame has a first positioning portion for engaging the interference member and a pressing unit pressed to the pressing portion of the frame, and is connected to the pressing portion and: And a first second positioning portion. The backlight module of the present invention comprises a frame, a backlight unit and a positioning device/frame having four frame edges connected thereto and a light unit disposed in the frame by the frame boundary U; the four interference portions are respectively disposed in the frame In the frame, each of the positioning members has a pressing portion that connects the two == to the frame of the frame, and connects the first back cover to the portion of the frame and the portion of the corner. The - position-the first positioning part and the second fixed=right backlight unit are respectively disposed in the frame 卞 Jw Yue Luo at the position of the locating disparity position, which is compared with the previous position of the long strip makeup. Use less material in strips. The same positioning function can be achieved. 6 1337283 is not disposed on both sides of the frame of the backlight module. FIG. 2 is an exploded perspective view showing the preferred embodiment of the positioning device of the backlight module of the present invention including four positioning members. And four interfering portions provided at the corners of the pivot frame 2 of the backlight module; FIG. 3 is a perspective view showing the four positioning members of the preferred embodiment for cooperating with the interference portions to be positioned at the four corners of the frame Department;
