[0032] Specifically, when using a plastic lamp holder with a nested structure, first, the user starts the installation operation. The user can fix the fixing plate 1 on the wall or ceiling by passing the screws through the fixing holes 3. Then, the bulb 7 is placed inside the quick-release seat 6 and the quick-release seat 6 is rotated. The threaded seat 8 and the inner wall of the quick-release seat 6 cooperate to tighten the bulb 7 to the inner wall of the quick-release seat 6. At the same time, the contact piece 9 on the top of the threaded seat 8 also fits with the connecting column 10 inside the quick-release seat 6. At this time, the quick-release seat 6 is placed inside the base 4, and then the sliding ring 5 is manually slid upward. Under the push of the sliding ring 5, the spring 14 is pressed The force contracts, and the quick-release seat 6 continues to be extended into the base 4. When the quick-release seat 6 reaches the end of the inner wall of the base 4, the sliding ring 5 is released. Under the rebound action of the spring 14, the sliding ring 5 returns to its original position and pushes the rolling ball 12 inside the base 4 to roll into the inner wall of the ball groove 11 of the quick-release seat 6. After the rolling ball 12 rolls into the ball groove 11, the friction between the rolling ball 12 and the ball groove 11 and the pressure of the spring 14 are used to quickly lock the quick-release seat 6, thereby completing the quick locking of the quick-release seat 6, thereby achieving the effect of efficiently and quickly installing the light bulb 7, providing users with a convenient lighting solution.

[0033] Reference Figure 5The inner wall of the base 4 is provided with a locking hole 17, and the inner wall of the locking hole 17 is smoothed to ensure that the connecting column 10 and the wedge block 21 are smoothly inserted therein. The outer wall of the connecting column 10 is provided with a groove 16, and the shape and size of the groove 16 match the wedge block 21, which can ensure that the wedge block 21 is tightly embedded therein, providing a stable locking force. The inner wall of the locking hole 17 is fixedly connected to the bottom plate 18, and the side wall of the bottom plate 18 is fixedly connected to the telescopic column 19. One end of the telescopic column 19 is fixedly connected to the wedge block 21. The wedge-shaped design of the wedge block 21 enables it to slide smoothly to one side when squeezed by the connecting column 10, thereby compressing the telescopic column 19 and the spring 20. The wedge block 21 is slidably connected to the inner wall of the groove 16, and the outer wall of the telescopic column 19 is provided with a spring 20. One end of the spring 20 is fixedly connected to the side wall of the bottom plate 18, and the other end of the spring 20 is fixedly connected to the side wall of the wedge block 21.

[0034] Specifically, during installation, the connecting column 10 inside the quick-release seat 6 begins to perform a key action during the installation process. The connecting column 10 will enter the interior of the base 4 and contact the locking hole 17 inside the base 4. At the same time, the wedge block 21 inside the base 4 will be squeezed by the connecting column 10. When the connecting column 10 squeezes the wedge block 21, the telescopic column 19 and the spring 2 20 are compressed. When the connecting column 10 continues to be inserted into the locking hole 17, the spring 20 is continuously compressed to store elastic potential energy. When the groove 16 on the outer wall of the connecting column 10 moves to the position of the wedge block 21, the squeezing force on the wedge block 21 disappears. At this time, the telescopic column 19 and the spring 20 are compressed. The column 19 and the second spring 20 rebound and push the wedge block 21 to the inside of the groove 16. The wedge block 21 quickly slides into the groove 16 under the elastic force of the second spring 20. The wedge block 21 cooperates with the groove 16 to achieve the locking of the connecting column 10, thereby completing the locking of the connecting column 10, thereby realizing efficient and safe connecting column 10 and power-on column 15. Through this locking mechanism, not only can the installation and locking of the connecting column 10 be quickly realized, but also the stability and safety of the connection can be guaranteed, preventing problems such as loosening or poor contact during use, and providing reliable protection for the normal operation of the plastic lamp holder.

[0035] Working principle: When using a plastic lamp holder with a nested structure, the user can first fix the fixing plate 1 on the wall or ceiling by passing the screw through the fixing hole 3, and then put the bulb 7 into the quick-release seat 6 and rotate the quick-release seat 6. The threaded seat 8 and the inner wall of the quick-release seat 6 cooperate with each other to tighten the bulb 7 to the inner wall of the quick-release seat 6. At the same time, the contact piece 9 on the top of the threaded seat 8 also fits with the connecting column 10 inside the quick-release seat 6. At this time, put the quick-release seat 6 into the base 4 and manually slide the sliding ring 5 upward. Under the push of the sliding ring 5, the spring 14 is forced to shrink. At this time, continue to extend the quick-release seat 6 into the base 4. When the quick-release seat 6 extends to the end of the inner wall of the base 4, release the sliding ring 5. Under the rebound action of the spring 14, the sliding ring 5 returns to its original position. And push the rolling ball 12 inside the base 4 to roll into the inner wall of the ball groove 11 of the quick-release seat 6, thereby completing the quick locking of the quick-release seat 6, thereby achieving the effect of efficient and fast installation of the light bulb 7. During installation, the connecting column 10 inside the quick-release seat 6 will enter the interior of the base 4 and contact the locking hole 17 inside the base 4. At the same time, the wedge block 21 inside the base 4 will be squeezed by the connecting column 10, so that the telescopic column 19 and the spring 2 20 are compressed. When the groove 16 on the outer wall of the connecting column 10 moves to the position of the wedge block 21, the squeezing force on the wedge block 21 disappears, and the telescopic column 19 and the spring 2 20 rebound and push the wedge block 21 to the inside of the groove 16, thereby completing the locking of the connecting column 10, thereby achieving efficient and safe connecting column 10 and power column 15.
