Taking photos is indispensable, and mobile phone photography has become the most convenient way to capture images anytime, anywhere, making it extremely convenient.

[0003] While existing smartphones have flashlights, their fill light effect is often unsatisfactory. In response, some external fill lights have appeared on the market. However, the height at which these fill lights are fixed to the phone is fixed, which leads to overexposure in some scenes and underexposure in others, causing great inconvenience to users.

[0004] Therefore, there is an urgent need to develop a height-adjustable supplementary lighting to meet people's application needs. Utility Model Content

[0005] The purpose of this invention is to provide a stretching mechanism and supplementary lighting that can be height-adjusted according to different application scenarios.

[0006] This utility model provides a tensioning mechanism, including a first connector for connecting a first component. The first connector extends along its length and has a sliding space through its middle portion. Sliding teeth are arranged oppositely on the two inner sidewalls of the sliding space. The sliding teeth are arranged along the length of the first connector and are wavy with staggered protrusions and recesses. The first connector can be inserted into or pulled out of the first component. A pair of elastic posts are provided on the first component. When the elastic posts are located in one of the recesses of the sliding teeth, the first component and the first connector are locked relative to each other.

[0007] Furthermore, the first component includes a sliding seat, on which a fixing seat for mounting the elastic column is provided, the fixing seat being located within the sliding space of the first connector.

[0008] Furthermore, the fixed base is provided with a mounting groove, the elastic post is installed in the mounting groove, the mounting groove has an opening facing the sliding tooth, and part of the elastic post extends out of the mounting groove through the opening to cooperate with the sliding tooth.

[0009] Furthermore, the size of the opening is smaller than the diameter of the elastic column.

[0010] Furthermore, the first component also includes a cover that fits onto the sliding seat. The cover has a recessed sliding groove. The sliding groove extends in the same direction as the length extension direction of the first connector. One end of the sliding groove has an inlet and outlet.

[0028] The directional terms such as "up," "down," "left," "right," "front," "back," "top," and "bottom" (if present) used in the specification and claims of this utility model are defined according to the position of the structures in the drawings and the relative positions of the structures, and are only for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed in this application.

[0029] Please see Figures 1-8This utility model discloses a stretching mechanism 30, including a first connector 31 connecting a first component 10. The first connector 31 extends along its length, and a sliding space 311 is formed through its central portion. Sliding teeth are arranged oppositely on the two inner sidewalls of the sliding space 311. The sliding teeth are arranged along the length of the first connector 31. Furthermore, the sliding teeth are wavy and have staggered protrusions 312 and recesses 313. Part of the first connector 31 can extend into or extend out of the first component 10. A pair of elastic posts 13 are provided on the first component 10. When the elastic post 13 is located in one of the recesses 313 of the sliding teeth, the first component 10 and the first connector 31 are locked relative to each other. In this embodiment, during the process of the first connector 31 being stretched outward or inserted inward into the first component 10, the length of the first connector 31 extending out of the first component 10 can be adjusted by the cooperation of the elastic post 13 and the recess 313. In this embodiment, the elastic post 13 is cylindrical.

[0030] Please see Figures 5-7 The first component 10 includes a sliding seat 11 and a cover 12 that covers the sliding seat 11. The sliding seat 11 is provided with a fixing seat 111 for mounting the elastic column 13. The fixing seat 111 is located in the sliding space 311 of the first connector 31. Furthermore, the fixing base 111 is provided with a mounting groove 1111, and the mounting groove 1111 has an opening facing the sliding tooth. The elastic post 13 is installed in the mounting groove 1111, and part of the elastic post 13 extends out of the mounting groove 1111 through the opening to cooperate with the sliding tooth. In this embodiment, because the elastic post 13 is inserted into the mounting groove 1111, the size of the opening is smaller than the diameter of the cross-section of the elastic post 13 so as to house the elastic post 13 in the mounting groove 1111 and prevent it from easily falling out of the mounting groove 1111. In particular, when the protrusion 312 of the sliding tooth presses the elastic post 13 along the sliding direction during the sliding process, it can ensure that the elastic post 13 always remains in the mounting groove 1111.

[0031] Please continue reading. Figure 7 In this embodiment, the shielding cover 12 is recessed with a sliding groove 121. The extending direction of the sliding groove 121 is the same as the length extending direction of the first connector 31. One end of the sliding groove 121 is provided with an inlet and outlet. The first connector 31 extends into or is pulled out of the sliding groove 121 from the inlet and outlet.

[0032] In other embodiments, the sliding groove 121 can also be disposed on the sliding seat 11, that is, the fixed seat 111 is located in the sliding groove 121, and the sliding teeth of the first connecting member 31 can slide between the elastic column 13 in the fixed seat 111 and the groove wall of the sliding groove 121.

[0033] Please see Figures 1-3 and Figure 8 The stretching mechanism 30 further includes a second connector 32 connecting the second component 20. The first connector 31 and the second connector 32 are rotatable about a pivot 33. More specifically, the angle between the first connector 31 and the second connector 32 rotating about the extended axis AA of the pivot 33 is 0° to 180°. In this embodiment, when the angle between the first connector 31 and the second connector 32 is 0°, the volume is minimal, facilitating storage and carrying; when the angle between the first connector 31 and the second connector 32 is 90°, it meets the requirements of the first scenario; when the angle between the first connector 31 and the second connector 32 is 180°, it meets the requirements of the second scenario. In other embodiments, the angle between the first connector 31 and the second connector 32 is within the range of 0° to 180° to suit specific scenario requirements in different environments.

[0034] Please continue reading. Figures 1-8 This utility model also discloses a supplementary lighting lamp, including the aforementioned tensioning mechanism 30. More specifically, the second component 20 is provided with a lighting device 21, and the first component 10 is provided with a fixing device 14 for fixing to an external device.

[0035] More specifically, the fixing device 14 is a magnetic suction assembly mounted on the first component 10 for cooperating with the magnetic attraction structure of an external device. The first component 10 is also provided with a makeup mirror 15, which is disposed on the opposite side of the first component 10 where the fixing device 14 is located.

[0036] In this embodiment, when the angle between the first connector 31 and the second connector 32 is 0°, the lighting device 21 is located on the outward side of the second component 20. This has the advantage that the lighting device 21 can emit light outwards without being blocked by the first component 10 at any angle between the first component 10 and the second component 20 (0° to 180°). Furthermore, the magnetic component is located on the outward side of the first component 10. This has the advantage that the magnetic component can be attached to an external device at any angle between the first component 10 and the second component 20 (0° to 180°). At this time, the makeup mirror 15 is located on the side of the first component 10 facing the second component 20. This has the advantage that, since the makeup mirror 15 is made of glass, when the fill light is in its retracted state, the makeup mirror 15 being located between the first component 10 and the second component 20 can prevent the makeup mirror 15 from breaking due to collisions with other items while stored in the backpack.

[0037] The stretching mechanism 30 and the fill light provided by this utility model, through the sliding arrangement of the first connecting member 31 and the first component 10 and the locking cooperation between the elastic column 13 on the first component 10 and the first connecting member 31, enable the stretching mechanism 30 and the fill light to achieve height adjustment according to different application scenarios, thereby meeting the exposure position requirements of different application scenarios.

[0038] Furthermore, the angle adjustment from 0° to 180° can be achieved around the pivot 33 via the first connector 31 and the second connector 32, making the stretching mechanism 30 and the fill light smaller and more portable when stored, and allowing them to be opened at different angles to suit more environmental scenarios when in use. In addition, the makeup mirror 15 is provided on the fill light to facilitate people to tidy their appearance before taking photos, which is convenient and practical. Therefore, the stretching mechanism 30 and the fill light of this utility model are very popular.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
