[0024] In this embodiment, the light guide strip is generally made of PVC material and TPU material or optical fiber material, etc., which has a certain elasticity and softness. The connecting block 5 is passed through the opening 102 at the top of the first light guide strip 1 and the second light guide strip 2 respectively, so that the connecting block 5 is located inside the groove 101. At this time, the card slot 501 at the bottom of the connecting block 5 covers the surface of the card block 11. The connecting block 5 is located at the connection between the first light guide strip 1 and the second light guide strip 2, so that the first light guide strip 1 and the second light guide strip 2 are connected and fixed, which is convenient for adjusting the length of the light guide strip according to actual use, and at the same time reduces the waste of the light guide strip after cutting. By plugging the power interface 31 into a power source, the light bulb 32 can be lit, and the first light guide strip 1 and the second light guide strip 2 transport the lit light. Example

[0025] like Figure 1-Figure 5 As shown, the pull rod 4 is movably installed on the inner wall of the mounting block 3, the bottom of the pull rod 4 is fixedly connected with a pressure block 41, the pressure block 41 is located on the inner side of the slot 301, a positioning rod 33 is fixedly installed inside the mounting block 3, one end of the surface of the pull rod 4 is fixedly connected with a fixing ring 42, the surface of the pull rod 4 is provided with a spring 43, the spring 43 is located on the top of the fixing ring 42, a connecting rod 44 is movably installed on the bottom of the fixing ring 42, the bottom end of the connecting rod 44 is movably connected with a pressure rod 45, the surface of the pressure rod 45 is provided with a slide groove 451, one end of the pressure rod 45 is located on the inner side of the slot 301, and the surface of the positioning rod 33 is movably connected to the inner wall of the slide groove 451.
