When the reel type cold light warning triangle in accordance with the present invention is not in use, as shown in FIGS. 2-4, the cold light warning piece 42 of the cold light reel assembly 40 is wound around the rotary shaft 41 and partially connected to the support units 60, the coil spring 52 of the elastic return assembly 50 is in a relaxed position, while the springs 62 of the support units 60 are compressed to pull the rods 63 into the hollow cylinders 61 in such a manner that the push portions 631 of the rods 63 are locked in a first locked position by leaning against the first annular flanges 613 of the hollow cylinders 61.
To pull out the cold light warning piece 42, the user needs to pull the pulling end 72 of the pulling member 70 to make the connecting end 71 pull the rods 63 of the support units 60, so that the rods 63 will be deformed to pass over the first annular flange 613 and released from the locked position. Then, keeping pulling the rods 63 can make the rods 63 slide out of the hollow cylinders 61 and make the rods 63 pivot around the connecting holes 611, so that the cold light warning piece 42 will be pulled out from the rotary shaft 41 and cause the rotary shaft 41 to rotate. Meanwhile, the rotation of the rotary shaft 41 will cause compression of the coil spring 52, as shown in FIG. 6. When the user continues to pull the rods 63 with the pulling member 70, the push portions 631 of the rods 63 will be deformed to pass over the second annular flange 614, and then, if the user stops pulling the pulling member 70, the push portions 631 of the rods 63 will be locked in a second locked position by leaning against the second annular flange 614, as shown in FIG. 5.
After the cold light warning piece 42 is pulled out, the user can choose to switch on the beeper 23 or cold light source of the cold light warning piece 42 by using the control buttons 92, providing different options to warn the vehicles behind. Furthermore, since the base 20 provides stable support for the reel type cold light warning triangle, the cold light warning triangle of the present invention can stand stably on the road without the use of other assembling tools.
When there is strong wind or vehicle passing by at high speed, the wind apertures 421 can reduce the wind pressure on the cold light warning piece 42, which improves the stability of the warning triangle. Furthermore, two anti-leak rubber pieces can be provided at two sides of the opening 22 to prevent water falling into the assembling chamber 21 in such a manner that the anti-leak rubber pieces each have one end fixed to the edge of the opening 22, and another ends of the anti-leak rubber pieces are overlapped.

The present invention is easy to put away when not in use, the user only needs to push the pulling member 70 downward, which will cause the push portions 631 of the rods 63 to deform and pass over the second annular flange 614, and the rods 63 will be released from the second locked position and pulled quickly back into the hollow cylinders 61 by the springs 62. Then the user just needs to slightly press the pulling member 70 when the rods 63 approach the first annular flange 613, the push portions 631 of the rods 63 will be deformed to pass over the first annular flange 613 and locked into the first locked positioned again. Meanwhile, the coil spring 52 will be decompressed to rotate the rotary shaft 41, as a result, the cold light warning piece 42 will be wound around the rotary shaft 41 automatically.
It is clear from the above description that the cold light warning piece 42 of the present invention can be pulled out or rolled up automatically simply by pulling or pushing the pulling member 70 without using any assembling or disassembling tools, which is very convenient. Furthermore, the base 20 provides stable support for the reel type cold light warning triangle. On top of that, the present invention is provided with the power system 80 which can generate enough power to satisfy the power consumption of the cold light warning triangle of the present invention, and the vehicle-electric-appliance plug 85 can supply power from vehicle to the cold light warning triangle of the present invention if the power system 80 cannot generate enough power.
