A plurality of circumferentially distributed heat dissipation fins 20 are integrally connected to the outer wall of the cylinder body 10. The plurality of heat dissipation fins 20 form an ellipsoidal structure, making the heat dissipation end of the ellipsoidal radiator round. An arc plate 30 is integrally connected to the top end of the cylinder body 10. A long plate 40 fixedly connected to its inner wall is arranged inside the arc plate 30. A first fixing mechanism 50 for the automotive low beam lamp board is arranged between the back surface of the long plate 40 and the front surface of the arc plate 30. A pair of long openings 60 are formed on the front surface of the long plate 40. A pair of externally threaded sleeves 80 distributed up and down are welded on the arc plate 30. The externally threaded sleeve 80 is threadedly connected to a second fixing mechanism 90 for the automotive low beam lamp board.

A pair of slide pieces 52 are threadedly connected to the left and right screw rods 51. The front surfaces of the two slide pieces 52 are integrally connected with slide blocks 53. The slide blocks 53 penetrate through the long openings 60. The front surfaces of the slide blocks 53 are integrally connected with clamping strips 54. The back surfaces of the clamping strips 54 are attached to the front surface of the long plate 40. The mutually approaching surfaces of the upper and lower clamping strips 54 are both arc surfaces. The thickness of the middle part of the clamping strip 54 is smaller than the thickness of the two end parts of the clamping strip 54. A connecting plate 70 is fixedly connected between the back surface of the long plate 40 and the front surface of the arc plate 30. The bottom ends of the left and right screw rods 51 are rotatably connected to the top surface of the lower connecting plate 70. The tops of the left and right screw rods 51 penetrate above the upper connecting plate 70.

[0022] In this implementation scheme, the automotive low beam lamp boards with various lengths and widths can be fixedly installed. At the same time, the clamping surface is provided with an arc surface. After clamping, the left and right shaking of the automotive low beam lamp board can be effectively avoided, and the installation firmness is high.

[0023] Specifically, the tops of the left and right screw rods 51 are integrally connected with a knob 100, and a cross slot is provided in the middle of the top surface of the knob 100.

[0024] In this embodiment, it is convenient to use a screwdriver to drive the left and right screw rods 51 to rotate, which can improve the firmness of the first fixing mechanism 50 of the automotive low beam lamp board after clamping the automotive low beam lamp board.

[0025] Specifically, the second fixing mechanism 90 of the automotive low beam lamp board includes an inner thread sleeve 91 threadedly connected to the outer thread sleeve 80. A fastening bolt 92 is threadedly connected to the front surface of the inner thread sleeve 91. The rear end of the fastening bolt 92 is integrally connected with a clamping post 93. A pressing block 94 is clamped on the clamping post 93. The cross section of the clamping post 93 is a regular hexagon. The pressing block 94 is a frustum structure, and a circular buffer pad is fixedly connected to the rear end of the pressing block 94.

[0026] In this embodiment, after the first fixing mechanism 50 of the automotive low beam lamp board fixedly installs the automotive low beam lamp board, the inner thread sleeve 91 can be threadedly connected to the outer thread sleeve 80. First, the fastening bolt 92 is threadedly connected, and then the pressing block 94 is clamped, and the pressing block 94 is made to abut against the front side of the automotive low beam lamp board, which can further reinforce the automotive low beam lamp board.

[0027] The working principle and usage process of the present utility model: Place the automotive low beam lamp board on the long board 40 and press it. Drive the knob 100 to rotate forward with a screwdriver, and the left and right screw rods 51 rotate forward. At this time, the two clamping strips 54 move closer to each other and clamp the automotive low beam lamp board. Then, the inner thread sleeve 91 is threadedly connected to the outer thread sleeve 80, the fastening bolt 92 is threadedly connected, and the fastening bolt 92 and the outer thread sleeve 80 are staggered and will not interfere. The pressing block 94 is clamped on the clamping post 93, and the fastening bolt 92 is continuously rotated forward, so that the pressing block 94 can tightly abut against the front side of the automotive low beam lamp board.
