[0028] The following further elaborates on the utility model in conjunction with the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the protection scope of the utility model.

[0029] As Figures 1 - 5 shown, a glow stick that can be retractably deformed includes a retractable part 1, a handle part 2, and a soft outer cover 3. The following elaborates on each part in detail:

[0030] As Figure 3 and Figure 5 shown, the retractable part 1 includes a strip-shaped spring steel strip 11 with an arc-shaped cross-section, a flexible light board 12 installed on the concave end face of the spring steel strip 11, and LED lamp beads 13 installed on the end face of the flexible light board 12 away from the spring steel strip 11. Therefore, after installing the LED lamp beads 13 on the spring steel strip 11 through the flexible light board 12, the light emitted by them can be used for warning, and the main function of the spring steel strip 11 is for retractable deformation. For the connection method between the flexible light board 12 and the spring steel strip 11, they can be connected by bonding.

[0031] As Figures 1 - 4 shown, the handle part 2 is installed at one end of the spring steel strip 11; the handle part 2 includes a circuit board 21 electrically connected to the light board and a battery 22 electrically connected to the circuit board 21. Therefore, after setting the handle part 2, people can directly hold the handle part 2 to use the glow stick. Of course, the circuit board 21 serves as the control center, and the battery 22 is used to provide power.

[0032] As Figures 1 - 4 shown, the soft outer cover 3 directly covers the retractable part 1 and the handle part 2, and the soft outer cover 3 is light-transmissive, so that the light emitted by the LED lamp beads 13 can pass through the soft outer cover 3 and shine outwards. Therefore, after setting the soft outer cover 3, it can not only play a role in waterproofing and other effects, protect the retractable part 1 and the handle part 2, but also improve the service life of the retractable part 1 and the handle part 2 to a certain extent.

[0033] By utilizing the bendable property of the spring steel strip 11 with an arc-shaped cross-section, the spring steel strip 11 can be curled and deformed with the LED lamp beads 13 facing outward. For example, the spring steel strip 11 can be directly curled around parts such as the arm, so that the light can shine outward through the soft outer sleeve 3, forming a warning effect, that is, the emitted light is warning light. In addition, since the soft outer sleeve 3 is soft, it will not affect the normal curling of the spring steel strip 11 during the curling deformation process of the spring steel strip 11. During use, just hit the front end of the end face where the spring steel strip 11 arches against the arm, and it can be curled around the arm. Then, wind the glow stick around the arm once, and the spring steel strip 11 can be completely curled around the arm. Immediately after releasing the glow stick, the effect of positioning the glow stick on the arm can be formed. At this time, since the LED lamp beads 13 face outward, their light can shine outward normally without being blocked by the arm.

[0034] Therefore, through the provision of the corresponding curling part 1, the handle part 2 and the soft outer sleeve 3, the present utility model can curl the glow stick around places such as the arm by utilizing the curlable and deformable property of the spring steel strip 11, that is, position the glow stick on the arm. This design will not affect the normal emission of the warning light, and moreover, this method can achieve the effect of freeing the hands, enabling people's hands to be used for other things. In addition, when people use the glow stick by holding it, they can directly hold it at the position of the handle part 2. In this way, since the cross-section of the spring steel strip 11 is arc-shaped, the spring steel strip 11 can obtain a stress that counteracts the gravitational force, and the spring steel strip 11 can be in a straightened and non-collapsed state for a long time, with good use effect and the light can also be used normally.

[0035] As Figure 3 shown, in this embodiment, a plurality of LED lamp beads 13 are provided, and the plurality of LED lamp beads 13 are evenly distributed on both sides of the flexible lamp board 12, so as to emit light with sufficient intensity on the glow stick and ensure the warning effect.

[0036] As Figures 1 - 4As shown, in this embodiment, the handle portion 2 further includes a housing 23, a control button 24 and a charging port 25 that are electrically connected to the circuit board 21 respectively; the housing 23 is located in the soft outer sleeve 3 and is connected to one end of the spring steel strip 11, and specifically, screws can be used for the connection between the two; both the circuit board 21 and the battery 22 are located in the housing 23; the control button 24 is installed on the housing 23; the charging port 25 is installed on the housing 23 and extends to an opening 34 at the end of the soft outer sleeve 3. Specifically, the control button 24 can have a switch function and a function for controlling the light color of the LED lamp beads 13. The function of the charging port 25 is to charge the battery 22. In addition, the function of the housing 23 is to protect the circuit board 21, the battery 22, etc. Of course, by uniformly installing some components on the housing 23, the handle portion 2 can be formed into a whole to facilitate disassembly and assembly, etc. Moreover, the housing 23 can also enable people to hold the glow stick more stably.

[0037] As Figures 1 - 4 shown, in this embodiment, a soft cover 31 that can be used to cover or open the opening 34 is further provided at the opening 34, and one side of the soft cover 31 is fixedly connected to the soft outer sleeve 3 through a connecting band 32. Specifically, the soft cover 31 and the connecting band 32 are integrally formed with the soft outer sleeve 3, so as to facilitate production and manufacturing. Therefore, the setting of the soft cover 31 can be used to protect the charging port 25 and prevent it from being invaded by rainwater, etc., while the connecting band 32 is mainly used to prevent the soft cover 31 from being lost.

[0038] As Figures 1 - 4 shown, in this embodiment, the soft outer sleeve 3 includes a main body 301 and a cover portion 302; the main body 301 covers a part of the retractable portion 1 and the handle portion 2; the cover portion 302 covers the other part of the handle portion 2 and is fixedly connected to the main body 301. Specifically, a part of the opening 34 is located on the main body 301, and the other part is located on the cover portion 302; at the same time, the connecting band 32 is connected to the cover portion 302. In addition, for the connection method between the main body 301 and the cover portion 302, they can be adhesively bonded with glue. Therefore, after the above settings, it is convenient to load the retractable portion 1 and the handle portion 2 at the main body 301, and then use the cover portion 302 to seal the opening to prevent water, dust, etc. from entering.

[0039] As Figure 2 shown, in this embodiment, a plurality of evenly distributed sunken lines 33 are provided on the surface of the end face of the soft outer sleeve 3 where the spring steel strip 11 is recessed, so that when the glow stick is retracted on the arm, the friction between the skin and the soft outer sleeve 3 can be increased, so as to improve the stability between the two.

[0040] In this embodiment, the inner wall of the soft outer sleeve 3 is closely attached to the curled portion 1 and the handle portion 2 in a matching manner, so that the spring steel strip 11 can better drive the corresponding part of the soft outer sleeve 3 to undergo curling deformation. In addition, for the thickness of the soft outer sleeve 3, it should not be too thick, otherwise it is likely to affect the light transmission effect of the light.

[0041] As Figure 3 shown, in this embodiment, the length of the flexible light board 12 is shorter than the length of the spring steel strip 11.

[0042] In this embodiment, the soft outer sleeve 3 is made of silica gel and is semi-transparent.

[0043] In this embodiment, the spring steel strip 11 is made of elastic steel.
