[0026] In an optional embodiment, the lamp body includes three parts: a head, a middle part, and a tail; the head, the middle part, and the tail are connected in sequence and are of an integral structure; the head of the lamp body is of an arc structure; an installation groove is provided on the head of the lamp body, and the installation groove is provided on the top surface and the rear surface of the head of the lamp body; a light-emitting component 1 is provided in the installation groove; wherein, the installation groove is of an arc structure; the light-emitting component 1 fills the installation groove; the light-emitting component 1 includes: an LED light source.

[0027] The tail of the lamp body is of a cuboid structure; a control unit 2 for controlling the lighting and extinguishing of the light-emitting component 1 is provided on the tail of the lamp body; the light-emitting component 1 is electrically connected to the control unit 2 through a power cord, and a switch button is provided on the front surface of the tail of the lamp body for controlling the switch of the light-emitting component 1 (LED light source); a color temperature adjustment button is further provided on the front surface of the tail of the lamp body for adjusting the color temperature of the light-emitting component 1; the control unit 2 includes a battery for supplying power to the light-emitting component 1; the control unit 2 includes a control board, and the control board is electrically connected to the switch button; the control board is electrically connected to the color temperature adjustment button.

[0028] In the present utility model, only the switch button and the color temperature adjustment button are provided on the front surface of the tail of the lamp body, so that when the operator holds it specifically, the left side, the right side, and the back surface of the tail of the lamp body can be held simultaneously.

[0030] Between the light-emitting component 1 and the control unit 2 and on the lamp body (specifically, as Figure 1 shown, on the upper side surface of the tail of the lamp body) an installation hole 3 is provided, and the installation hole 3 is of a long strip hole structure; a rotating component is provided in the installation hole 3 for rotating to align the center of the light-emitting component 1 with the center of the head of the polishing machine.

[0031] Specifically, for polishing machines of different specifications, it is necessary to rotate the rotating assembly so that the exact center of the light-emitting component 1 aligns with the exact center of the head of the polishing machine; for a polishing machine with a moderate specification, the rotating assembly does not need to rotate within the mounting hole 3, and at this time, the exact center of the light-emitting component 1 exactly aligns with the exact center of the head of the polishing machine; for a polishing machine with a relatively large specification, the lighting device needs to be offset forward and inward relative to the polishing machine, that is, the lighting device needs to move forward, and the rotating assembly needs to be close to the head of the polishing machine; for a polishing machine with a relatively small specification, the lighting device needs to be offset backward and outward relative to the polishing machine, that is, the lighting device needs to move backward, and the rotating assembly needs to be away from the head of the polishing machine.

[0032] In an alternative embodiment, the rotating assembly includes: a rotating member 4 and a rotating shaft 5; the rotating member 4 is disposed within the mounting hole 3; the rotating member 4 is adapted to the mounting hole 3; in the present invention, the shape of the rotating member 4 is a cuboid structure with a slightly curved arc; its two side surfaces are open structures, namely the left side surface and the right side surface; the front surface, the rear surface, the top surface and the bottom surface are closed structures; the rotating member 4 is connected to the mounting hole 3 through the rotating shaft 5 so that the rotating member 4 rotates around the central axis of the rotating shaft 5. In the present invention, the middle part of the front surface of the rotating member 4 is connected to the mounting hole 3 through the rotating shaft 5; the central axis of the rotating shaft 5 is perpendicular to the front surface of the rotating member 4; the front surface of the rotating member 4 is parallel to the front surface of the lamp body (as Figure 1 shown is the front surface of the lamp body); after assembly, the rotating member 4 can rotate around the central axis of the rotating shaft 5 by a certain angle to adjust the lighting direction of the light-emitting component 1. In the present invention, the rotating member 4 can rotate around the central axis of the rotating shaft 5 within a range of ±4.5°; thereby realizing that the light-emitting component 1 can flexibly swing within a range of ±4.5° through the rotating assembly to meet the lighting requirements of polishing machines of different specifications.

[0033] Specifically, for a polishing machine with a moderate specification, the rotating member 4 does not need to rotate within the mounting hole 3, and at this time, the rotating member 4 is just completely within the mounting hole 3, and the exact center of the light-emitting component 1 exactly aligns with the exact center of the head of the polishing machine; for a polishing machine with a relatively large specification, the lighting device needs to be offset forward and inward relative to the polishing machine, that is, the lighting device needs to move forward relative to the polishing machine, and Figure 1 in, the rotating member 4 needs to rotate to the right, the top of the rotating member 4 is close to the head of the polishing machine (leaking from the right side within the mounting hole 3), and the bottom of the rotating member 4 needs to be away from the head of the polishing machine (leaking from the left side within the mounting hole 3), so that the exact center of the light-emitting component 1 exactly aligns with the exact center of the head of the polishing machine with a relatively large specification; for a polishing machine with a relatively small specification, the lighting device needs to be offset backward and outward relative to the polishing machine, that is, the lighting device needs to move backward relative to the polishing machine, and Figure 1In this case, the rotating member 4 needs to rotate to the left. The top of the rotating member 4 needs to move away from the head of the polishing machine (leaking out from the left side inside the mounting hole 3), and the bottom of the rotating member 4 needs to approach the head of the polishing machine (leaking out from the right side inside the mounting hole 3). This exactly makes the center of the light-emitting component 1 exactly align with the center of the head of the polishing machine with a smaller specification.

[0034] Furthermore, a damping structure is provided on the rotating shaft 5 for providing appropriate resistance during the rotation process to ensure that the light-emitting component 1 can remain at the set angle after adjustment and prevent accidental changes in the position of the light-emitting component 1.

[0035] Even further, the rotating member 4 can be made of a sturdy material, such as: metal; this can withstand the mechanical stress and vibration that may be encountered during use.

[0036] In the present utility model, by adjusting the angle of the rotating assembly, precise control of the illumination direction of the light-emitting component 1 can be achieved to ensure sufficient illumination of the polishing area.

[0042] The left and right sides of the rotating member 4 are long strip-shaped hole structures; for a polishing machine with a moderate specification, the fixing screw 8 directly passes through the center positions of the left and right sides of the rotating member 4 in sequence and is threadedly connected to the threaded hole on the machine head of the polishing machine or the threaded hole on the fixing member 6; for a polishing machine with a relatively large specification, the lighting device needs to move forward relative to the polishing machine, then the fixing screw 8 directly passes through the lower positions of the left and right sides of the rotating member 4 in sequence and is threadedly connected to the threaded hole on the machine head of the polishing machine or the threaded hole on the fixing member 6, so that the lighting device can move forward relative to the polishing machine; for a polishing machine with a relatively small specification, the lighting device needs to move backward relative to the polishing machine, then the fixing screw 8 directly passes through the upper positions of the left and right sides of the rotating member 4 in sequence and is threadedly connected to the threaded hole on the machine head of the polishing machine or the threaded hole on the fixing member 6, so that the lighting device can move backward relative to the polishing machine.

[0043] In an alternative embodiment, the fixing member 6 is a circular ring structure; the outer surface of the machine head of the polishing machine is adapted to the inner surface of the fixing member 6, so that the fixing member 6 can be firmly installed on the machine head of the polishing machine.

By connecting with the connecting screw 7, it is convenient for the disassembly and assembly of the first connecting frame and the second connecting frame. Among them, a threaded hole is provided on the first connecting frame in the fixing member 6 for the fixing screw 8 to pass through the rotating member 4 and be threadedly connected to the threaded hole.

[0044] In another alternative embodiment, the heads of the first connecting frame and the second connecting frame can be snap-connected, and the present invention does not limit the connection method of the heads of the first connecting frame and the second connecting frame.

[0045] The fixing member 6 includes a variety of first connecting frames and second connecting frames that are detachably connected. This can adapt to the fixation of the machine heads of polishing machines with different specifications.

[0046] The fixing member 6 is provided with a plurality of reinforcing ribs to enhance the structural strength of the fixing member 6.

[0047] Furthermore, the fixing screw 8 is designed with an anti-loosening structure, which can prevent loosening after long-term use and ensure that the lighting device can be stably installed on the machine head of the polishing machine.

[0048] In the present utility model, after the fixing component 6 fixes the head of the polishing machine, the light-emitting component 1 of the lighting device is located in front of the head of the polishing machine, and the exact center of the light-emitting component 1 of the lighting device is exactly aligned with the exact center of the head of the polishing machine. In this way, during the polishing operation of the polishing machine, lighting can be conveniently and precisely carried out. Moreover, the head of the polishing machine is located within the arc-shaped structure at the head of the lamp body where the light-emitting component 1 is located, so that all the front faces of the head of the polishing machine can be illuminated, preventing the state of illumination on the left but not on the right or illumination on the right but not on the left.
