[0002] At present, the headlights of vehicles are the most important lighting components on cars. The national standard has strict requirements and technical indicators for the performance indicators of headlights. Therefore, headlights must undergo rigorous testing and verification and can only be installed on vehicles put on the market after meeting various technical indicators.

[0003] There have been many technical innovations in automobile lighting technology, from adaptive headlight systems to LED light sources, to laser light sources, etc., and the technology of automobile lighting is changing with each passing day. When driving at night, high beams can improve vision, expand the field of vision, and provide a good driving environment for drivers. However, the behavior of "abusing high beams" has always been at the top of the public opinion survey on traffic bad habits, becoming the most hated traffic bad habit, and it has also become one of the main causes of nighttime traffic accidents.

[0004] In view of this situation, major vehicle manufacturers are actively launching automatic high-beam headlights, which are implemented in the form of "variable shielding" and "LED matrix". The car headlights can achieve different states of high beam through specific hub positions or the lighting, dimming and extinguishing of a single LED to greatly improve the driver's field of vision without causing adverse effects on oncoming vehicles and vehicles in front, such as glare.

[0005] Therefore, vehicle headlights need to be tested after production. However, due to the different sizes of existing vehicle headlights, different types and sizes of headlights need to be fixed by different fixing devices when testing headlights of different types and sizes. Then the vehicle headlights are tested, which results in different fixing devices needing to be replaced to fix the vehicle headlights for testing. Utility Model Content

[0008] Preferably, the positioning rod is connected to the clamping block through an elastic component, which includes a limit block fixedly arranged on the ends of multiple positioning rods that are away from one end of adjacent clamping blocks, and a limit spring sleeved on the body of each positioning rod and fixedly connected at both ends of the clamping block end face and the limit block.

[0009] Preferably, each positioning rod has a plurality of slots evenly spaced along the length direction of the rod body, and the positioning assembly includes a plurality of fixing rods which are parallel to each other and adjacent to the sides of the plurality of positioning rods, a fixing rod which is arranged on the sides of the fixing rods and passes through the slots, a linkage rod which has a length direction perpendicular to the length direction of the fixing rod rod body, passes through the clamp block and is fixedly connected to the plurality of fixing rods, a control block which is arranged at the end of the linkage rod outside the clamp block, and a limit member which is arranged in the clamp block and limits the position of the linkage rod.

[0010] Preferably, the limiting member comprises a return spring sleeved on the rod body of the linkage rod, and two ends of the return spring are respectively fixedly connected to the rod body of the linkage rod and the inner wall of the clamping block.

[0011] Preferably, the lifting assembly includes a control rod arranged on one side of the two clamping blocks in the vertical direction, a bidirectional screw rod inserted into a control groove opened on the side of the control rod adjacent to the two clamping blocks, and two lifting blocks respectively sleeved on the rod body at both ends of the bidirectional screw rod through threaded connections. The bidirectional screw rod is driven by a driving motor arranged on the control rod.

[0012] The beneficial effects of the utility model are as follows: vehicle headlights of different models and sizes are directly placed between the two clamping blocks, and then the two clamping blocks are driven close to each other by the lifting assembly, so that the position of the headlights can be fixed by the two clamping blocks, and a plurality of positioning rods are movably penetrated on the adjacent end faces of the two clamping blocks.
