[0002] In the working environment, objects such as screws and nuts often fall into dark corners. At this time, an instrument that can quickly locate and pick up objects is needed. A flashlight with a search function has such a function. Its structure is usually that the main body of the flashlight can be extended, and the lighting part has a magnetic suction function to absorb objects. A flashlight with this function needs to have a long wire in the retractable main body. As the main body is extended and retracted, the wire is easily damaged, and the product life is short. In addition, the lighting angle of the flashlight cannot be adjusted. Utility Model Content

[0003] The technical problem to be solved and the technical task proposed by the utility model are to overcome the defect that the lighting angle of the existing flashlight with the object-finding function cannot be adjusted, and to provide a lighting device that is convenient for finding and picking up fallen objects.

[0014] Preferably, the light guide at one end of the third end has a protruding section extending from the second light focusing portion to the first end, and the second light focusing portion has a protective tube, which covers the protruding section, thereby increasing the structural firmness of the third end, especially protecting the light guide and preventing the light guide from being damaged.

[0015] Preferably, the third end has a sleeve-shaped connecting portion, the second light focusing portion is fixed in the sleeve-shaped connecting portion, and when the third end is connected to the first end, the first end extends into the sleeve-shaped connecting portion. Accordingly, light leakage at the connecting portion between the third end and the first end is avoided, and as much light as possible from the first end is guided into the light guide body, thereby reducing light loss.

[0016] Preferably, the fourth end is provided with a magnetic attraction member so as to pick up the object by magnetic force after the fallen object is found.

[0017] The utility model separates the lighting device into two parts. The first part can be used for independent lighting, such as a flashlight. The first part has a first end and a second end. The first end is configured to emit lighting light outwards. The second part is bendable. The second part has a third end, a fourth end, and a light guide that transmits light from the third end to the fourth end. The third end is detachably connected to the first end so that the second part can be connected to the first part or the second part can be removed from the first part. Accordingly, the first part can be used alone to emit lighting light outwards through the first end to achieve lighting, and the second part can also be connected to the first part for assembly. Since the second part is bendable, the lighting direction and the reach distance of the fourth end can be adjusted by bending the second part to adjust the direction of the fourth end, which is conducive to finding fallen objects. The lighting device is particularly suitable for finding fallen objects in a narrow space.

[0018] The utility model provides a magnetic attraction component at the fourth end so as to pick up the object through magnetic force after the fallen object is found. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention is described in detail below in conjunction with specific embodiments and drawings.

[0037] like Figure 1-5 As shown, the lighting fixture includes a first part 100 and a second part 200 .

[0038] The first part 100 is a flashlight that can be used for independent lighting. The first part 100 includes a housing 120, a circuit board 130 located in the housing, a power source 140 and a light source 150. The first part 100 has a first end 101 and a second end 102 and is in a rod shape. A clip 160 is arranged outside the housing 120, and the first part can be clipped into a pocket like a pen through the clip, so the first part can be called a pen-shaped flashlight.

[0039] The first end 101 of the first part 100 is configured to emit illumination light outward. Specifically, the first end 1011 has a reflective bowl as a first light focusing portion 110 to focus the illumination light generated by the light emitter in the first part and irradiate it outward through the light-transmitting lens 170. The second end 102 of the first part 100 is provided with a switch 180, which can be pressed to light up or turn off the light emitter.

[0040] The second part 200 has a third end 201, a fourth end 202, and a light guide 210 that transmits light from the third end to the fourth end. A bendable and shaped sheath 220 is connected between the third end and the fourth end. The sheath is a corrugated tube or a rubber hose, and the light guide 210 is an optical cable arranged in the sheath 220. Accordingly, the second part is bent and fixed in shape by the sheath and the optical cable, and the adjusted lighting direction is maintained.

[0041] The third end 201 is detachably connected to the first end 101 so that the second part can be connected to the first part or the second part can be removed from the first part. Therefore, the first part can be used alone for lighting, or the second part can be assembled to the first part for lighting. When the first part is used alone for lighting, it is convenient to use. When the second part is assembled to the first part for lighting, the fourth end of the second part can be extended to a farther position, and the direction of the fourth end can be adjusted by bending to change the lighting direction. In order to facilitate assembly and disassembly, the third end is connected to the first end by threads or clamping.

[0042] The third end 201 is provided with a second light focusing portion 230 to guide the illumination light from the first part into the light guide. The second light focusing portion 230 is an arc-shaped reflective surface and the center of curvature of the arc-shaped reflective surface is located in the direction of the second light focusing portion biased toward the first end, which is opposite to the first light focusing portion 110 when the first part and the second part are assembled together. The end of the light guide 210 located at the third end has a protruding section 211 extending from the second light focusing portion to the first end, and the protruding section 211 is located between the second light focusing portion 230 and the first light focusing portion 110. Accordingly, the light generated by the luminous body is confined between the second light focusing portion and the first light focusing portion and is conducive to entering the light guide, reducing light loss. In order to protect the light guide and prevent damage to the light guide, the second light focusing portion 230 has a protective tube 231, and the protective tube 231 covers the protruding section 211. The third end 201 has a sleeve-shaped connecting portion 240 , and the second light focusing portion 230 is fixed in the sleeve-shaped connecting portion 240 . When the third end is connected to the first end, the first end 101 extends into the sleeve-shaped connecting portion 240 .

[0043] A magnetic attraction member 250 , such as a permanent magnet, is fixed to the end surface of the fourth end 202 for attracting and picking up the object after finding it.
