[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 5The utility model provides a technical solution: a LED light source board testing device, including a test stand with a support plate 1. The test stand in this application is a prior art, and the test principle is not described in detail. It also includes a pair of clamps 2 locked to the top of the support plate 1 by a fastening component. During the test, the LED light source board is placed between the pair of clamps 2, and then the control handle drives the probe to descend and contact the light source board for testing. The fastening component is a screw 6 threadedly installed on the top of the support plate 1. A pull rod 4 is rotatably sleeved on the screw 6. The pull rod 4 is integrally formed into a square U-shaped structure, and the edges are all chamfered and smoothly transitioned. The advantage of this setting is that it avoids sharp corners from scratching the skin. The top of the clamping plate 2 is provided with a pair of through holes for the screws 6 to pass through. The through holes are adapted to the outer diameter of the screws 6. The top of the screws 6 is fixedly provided with an anti-slip cap 7. The side wall of the anti-slip cap 7 is provided with a groove. The limit card 8 is sleeved in the groove. The limit card 8 is integrally formed into an arc structure with an opening. The advantage of this arrangement is that it is easy to disassemble and assemble, which brings convenience to the assembly of the fastening component. The pull rod 4 is rotatably installed on the side wall of the limit card 8, and the top of the anti-slip cap 7 A slot is provided for accommodating the plug-in board 5, so that the plug-in board 5 is plugged into the screw 6 and the screw 6 is screwed in conjunction with the pull rod 4 to adjust the spacing of a pair of splints 2. The top of the splint 2 is respectively provided with a limit slot 3 at the position of the through hole. The width of the pull rod 4 is adapted to the limit slot 3. When adjusting the spacing of the splints 2, first rotate the pull rod 4 to make it perpendicular to the screw 6, and then slide the plug-in board 5 into the slot on the top of the anti-drop cap 7. At this time, the pull rod 4 and the limit card 8 are limited by the plug-in board 5 (can only rotate coaxially with the screw 6), and then the screw 6 is screwed through the pull rod 4. After the screw 6 is loosened, the position of the splint 2 on the support plate 1 is adjusted according to the specifications of the LED light source board to be tested. After the adjustment is completed, screw 6 is tightened. When the cam 5 is in the closed position, the cam 5 is in the closed position, and the cam 5 is in the closed position, so that the cam 5 can move upward and downward to prevent the cam 5 from sliding out of the closed position.
