The position of the light-transmitting hole in the middle part of the protective box 16 corresponds to the position of the hole in the middle part of the adjusting wheel 7.

[0032] By setting the fixed disc 3, the triangular plate 6 and the adjusting wheel 7, when it is needed to concentrate the illumination range to a point, the adjusting wheel 7 is first turned, at this time the plurality of slide bolts 5 will move along the track of the inclined hole 8 respectively, and the slide bolt 5 will drive the triangular plate 6 to move on one side of the inclined groove 4. At this time, by setting the side edges of the plurality of triangular plates 6 in contact with the inclined edges, the plurality of triangular plates 6 are circular.

[0034] By setting the clamping bolt 14, the resisting spring 13 and the clamping block 9, when rotating the adjusting wheel 7, first, the clamping block 9 is rotated, when the clamping block 9 rotates to the bottom of the protection box 16, the clamping block 9 will pass through the clamping bolt 14 from the top of the clamping bolt 14 under the action of the resisting spring 13, at this time, the plurality of clamping blocks 9 will move over the top of the clamping bolt 14, when the clamping block 9 stops rotating, at the same time, the clamping block 9 rotates between the two clamping bolts 14, through the action of the resisting spring 13 rebounding the clamping bolt 14, the two clamping bolts 14 will clamp the clamping block 9 in the middle, at this time, the single clamping block 9 will be limited between the two clamping bolts 14, thereby avoiding the problem that the adjusting wheel 7 automatically rotates when the position of the triangular plate 6 is adjusted, so as to fix the position of the adjusting wheel 7, at the same time, by setting the open hole on the top of the protection box 16, it is convenient to rotate the adjusting wheel 7, and by setting the fixed frame 17, it is convenient to place the lamp handle 1 later, the fixed frame 17 can stably fix the lamp handle 1 on the plane.

[0035] As shown in the figure, Figures 1 to 3 The refracting assembly includes an L-shaped frame 21 mounted on one side of the lamp handle 1, an L-shaped groove 29 is formed in the inside of the L-shaped frame 21, a moving groove 23 is formed in one side of the inside of the L-shaped groove 29, the length of the moving groove 23 is equal to the length of the L-shaped groove 29, a sliding block 24 is slidably connected to the outside of the moving groove 23, a refracting mirror 28 is rotatably connected to one side of the sliding block 24, a third knob 26 is rotatably connected to one side of one end of the L-shaped frame 21, a screw is fixedly connected to one side of the third knob 26, the screw away from the third knob 26 is threadedly connected to the inside of the sliding block 24 through the inside of the L-shaped frame 21, when the sliding block 24 moves to one side of the third knob 26, the position of the refracting mirror 28 corresponds to the position of the lamp head 2;

[0036] By using the refractive component, the light emitted from the lamp head 2 can be effectively refracted, allowing the light to illuminate gaps or obstacles that are difficult to see directly, thus expanding the range of application of the light. It is especially suitable for working environments in confined spaces or corners. In use, the refractive mirror 28 is moved to the front of the lamp head 2. By adjusting the angle of the refractive mirror 28, the light emitted from the lamp head 2 is refracted through the refractive mirror 28, refracting the light source in multiple directions. This allows the refracted light to illuminate corners and confined spaces, thus avoiding the problem of the lamp handle 1 being too large to fit in confined spaces. When encountering confined spaces requiring illumination, such as... Figure 2 As shown, firstly, slide the slider 24 inside the L-shaped groove 29. Then, the refracting mirror 28 is moved to the front of the lamp head 2 by the slider 24. By rotating the angle of the refracting mirror 28, the light source emitted from the lamp head 2 is reflected into a narrow space by the refracting mirror 28, making it easier for the user to observe. At the same time, through the L-shaped bracket 21, when refraction is not needed, the refracting mirror 28 can be slid along the track of the L-shaped groove 29 to a position where one end of the L-shaped bracket 21 is parallel to the lamp handle 1, thus facilitating the daily illumination of the lamp head 2. At the same time, through the third knob 26, when the refracting mirror 28 moves to the corresponding position of the lamp head 2, the slider 24 moves to one side of the third knob 26. Then, by rotating the third knob 26, the bolt passes through the side wall of the L-shaped bracket 21 and is threadedly connected to one side of the slider 24, thus fixing the position of the slider 24, which facilitates fixing the position of the refracting mirror 28.

[0037] like Figures 1 to 3 As shown, a second knob 25 is rotatably connected to one side of the slider 24, and a screw is fixedly connected to one side of the second knob 25. The end of the screw on one side of the second knob 25 away from the second knob 25 is connected to the internal thread of one end of the rotating column 27. A groove 22 is provided on the top of one end of the L-shaped frame 21. A first fixing clip 18 is slidably engaged with the outside of the groove 22. A second fixing clip 19 is slidably connected to the outside of one end of the L-shaped frame 21. The position of the first fixing clip 18 is located at the front end of the second fixing clip 19. The first fixing clip 18 and the second fixing clip 19 are L-shaped. One side of the bottom of the second fixing clip 19 is fixedly connected to one side of the lamp handle 1. One side of the bottom of the first fixing clip 18 is fixedly connected to one side of the protective box 16. A first knob 20 is rotatably connected to the top of the second fixing clip 19. A threaded bolt is fixedly connected to the bottom of the first knob 20. The end of the threaded bolt at the bottom of the first knob 20 away from the first knob 20 passes through the interior of the second fixing clip 19 and contacts the top of the L-shaped frame 21.

[0038] By setting the second knob 25, when adjusting the angle of the refractor 28, when the angle of the refractor 28 is adjusted, the second knob 25 is rotated to drive the screw rod and the threaded connection with one end of the rotating column 27, and then the angle of the refractor 28 is fixed, so that the fixation of different angles of the refractor 28 is facilitated, and the first fixing clamp 18 facilitates the sliding of the L-shaped frame 21, so that the distance between the refractor 28 and the lamp holder 2 can be adjusted, so that when different sizes of narrow spaces are encountered, the L-shaped frame 21 can be adjusted by moving, and the second fixing clamp 19 is arranged, which stabilizes the movement of the L-shaped frame 21, and when positioning the L-shaped frame 21, the first knob 20 is rotated to drive the threaded bolt to penetrate the inside of the second fixing clamp 19 and contact the top of the L-shaped frame 21, and then the threaded bolt is pressed against the L-shaped frame 21 and fixed in the inside of the second fixing clamp 19, so that the use of the refractor 28 is facilitated, and the first fixing clamp 18 is arranged in front of the second fixing clamp 19, which can avoid the problem that the threaded bolt blocks the sliding of the L-shaped frame 21 when the L-shaped frame 21 slides, and it should be noted that when the refractor 28 moves to one side of the lamp handle 1, one side of the first fixing clamp 18 will block the second knob 25, so that the slider 24 cannot move, at this time, the second knob 25 is rotated to drive the screw rod to move out of one side of the slider 24, at this time, since the refractor 28 is rotatably connected to one side of the slider 24 through the rotating column 27, the problem of the refractor 28 falling off can be avoided, and then when passing through one side of the first fixing clamp 18, the second knob 25 is reconnected to one side of the slider 24, so that the daily placement of the refractor 28 is facilitated.
