[0025] The utility model provides the following technical scheme:

[0026] Embodiment one

[0027] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a LED flashlight of focusing is facilitated, including flashlight body 3, the left side of flashlight body 3 is fixedly connected with fixed cylinder 5, adjusting mechanism 4 is arranged in the inside of fixed cylinder 5, the right side of flashlight body 3 is fixedly connected with base 1 is fixed cylinder 5 inside right side is provided with pull mechanism 2;

[0028] Adjusting mechanism 4 includes fixed ring 47, fixed ring 47 is fixedly connected on the right side of the periphery of fixed cylinder 5, sliding ring 44 is slidably connected in the inside of fixed ring 47, anti-skid ring 45 is fixedly connected on the periphery of sliding ring 44, inner gear 48 is fixedly connected in the inside of sliding ring 44, rotating gear 43 is engaged in the inside of inner gear 48, screw rod 41 is fixedly connected in the inside of rotating gear 43, screw rod 41 is rotatably connected in the inside of fixed cylinder 5, focusing piece 42 is threadedly connected on the periphery of screw rod 41, LED lamp 46 is provided on the right side of focusing piece 42, and LED lamp 46 is arranged in the left side of flashlight body 3.

[0029] Further, sliding groove corresponding to the motion trail of sliding ring 44 is formed in the inside of fixed ring 47, and fixed ring 47 is slidably connected in the inside of the sliding groove, so that sliding ring 44 can slide in the inside of fixed ring 47 by the sliding groove.

[0030] Further, fixed groove corresponding to the motion trail of rotating gear 43 is formed in the inside of fixed cylinder 5, and rotating gear 43 is rotatably connected in the inside of the fixed groove, so that rotating gear 43 is not easily affected by the rotation of fixed cylinder 5 during rotation, and the rotation of inner gear 48 can drive rotating gear 43 to rotate.

[0031] Further, limiting groove corresponding to the motion trail of focusing piece 42 is formed in the inside of fixed cylinder 5, and focusing piece 42 is slidably connected in the inside of the limiting groove, so that focusing piece 42 can be limited by the limiting groove, and focusing piece 42 can move left and right in the inside of fixed cylinder 5.

[0032] Embodiment Two

[0033] Please refer to Figures 1-4 And on the basis of Embodiment One, the pulling mechanism 2 further comprises a fixed rod 22 fixedly connected to the right side of the flashlight body 3, a fixed disc 24 slidably connected to the periphery of the fixed rod 22, a slide rod 23 fixedly connected to the right side of the fixed disc 24 and slidably connected to the inner side of the base 1, a fixed band 21 fixedly connected to the right side of the slide rod 23, and a spring 25 sleeved to the periphery of the fixed rod 22.

[0034] Further, the spring 25 is fixedly connected to the right side of the fixed disc 24 and the left side of the spring 25 is fixedly connected to the right side of the flashlight body 3. When the fixed band 21 is not subjected to external force, the elastic force of the spring 25 enables the fixed disc 24 to drive the slide rod 23 and the fixed band 21 to move, so that the fixed band 21 returns to the original position.

[0035] Further, the slide rod 23 has two, which are respectively fixedly connected to the top and the bottom of the right side of the fixed disc 24. When the fixed band 21 is subjected to external force, the slide rod 23 enables the fixed disc 24 to move, so that the fixed disc 24 can extrude the spring 25.

[0036] In actual operation, when the device is used, when the flashlight body 3 is not used, the user wants to hang the flashlight body 3 on the hand for carrying, the finger pulls the fixed band 21 outward, passes through the fixed band 21, drives the slide rod 23 to slide outward in the inner side of the base 1, and the slide rod 23 further drives the fixed disc 24 to move outward on the fixed rod 22. At this time, the spring 25 is compressed, and due to the elastic effect of the spring 25, an inward pulling force is generated on the finger, so that the fixed band 21 can be closely attached to the finger, can adapt to different finger thicknesses, and provides a stable hanging and carrying mode for the flashlight body 3. When the user releases the finger and no longer applies a pulling force, the restoring force of the spring 25 enables the fixed disc 24, the slide rod 23 and the fixed band 21 to return to the initial position or a balanced state close to the initial position, ensuring the stability and convenience of the flashlight body 3 in the carrying process, and also preventing the flashlight body 3 from accidentally falling to a certain extent.

[0037] When the flashlight body 3 needs to be focused, during the rotation of the threaded rod 41, the focusing piece 42 will move linearly along the axial direction of the threaded rod 41 under the constraint of the limiting groove inside the fixed cylinder 5. When the focusing piece 42 approaches the LED lamp 46, the light will gradually diverge after refraction through the focusing piece 42, so that the illumination range of the flashlight body 3 becomes wider. When the focusing piece 42 moves away from the LED lamp 46, the light is more convergent, and the light beam of the flashlight body 3 is focused, so that the illumination distance is farther and the central brightness is higher. In this way, the precise focusing function is realized, and the requirements of different illumination distances and ranges are met. The focusing piece 42 includes a focusing lens and a fixed frame, and the focusing lens is fixedly connected to the inside of the fixed frame.

[0038] It should be noted that the relational terms herein such as first and second, and the like, are used solely to distinguish one from another entity or action, without necessarily requiring or implying any such actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises... " does not, without more limitations, preclude the existence of further identical elements in the process, method, article, or apparatus that includes the recited element.
