[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 The utility model discloses an LED lamp bead testing fixture, comprising a placing plate 1 and LED lamp beads 10. A connecting slide 2 is arranged on the side of the placing plate 1. The LED lamp beads 10 are installed inside the slide 2. One side of the slide 2 is connected with several lead screws 3 by threads. A clamping plate 4 is arranged on the side of the slide 2 close to the lead screw 3. The clamping plate 4 and one end of the lead screw 3 are rotatably connected. A screw block 5 is arranged on the other end of each lead screw 3. A first elastic contact piece 6 is arranged on the inner wall of the slide 2 on the opposite side of the clamping plate 4. A second elastic contact piece 7 opposite to the first elastic contact piece 6 is arranged on the clamping plate 4. A switch 8 and a power supply 9 are arranged on the slide 2. The LED lamp beads 10 are pushed through the first elastic contact piece 6 and the second elastic contact piece 7 one by one. The power supply 9 will energize the LED lamp beads 10. If the LED lamp beads 10 light up, it means that the LED lamp beads 10 are normal. If the LED lamp beads 10 do not light up, it means that the LED lamp beads 10 are damaged.

[0025] A stop edge 11 is provided at the top of the opposite side of the slideway 2 and the clamping plate 4 , and a stop edge 11 is also provided at the top of the clamping plate 4 to limit the top of the LED lamp bead 10 .
