Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] For example, see Figures 1 to 6 The utility model provides a technical solution: an electric grinder lighting structure, comprising a main shell 1, one end of the main shell 1 is fixedly connected to a head shell 2, the interior of the main shell 1 is fixedly installed with a battery 4 and a motor 6 in a front-to-back distributed manner, a light-emitting circuit board 16 fixed by a nut is fixedly installed on the inner wall of one side of the outer periphery of the main shell 1, three equidistantly distributed lighting lamps 17 are fixedly installed on the surface of the light-emitting circuit board 16, a transparent ring cover 18 for preventing light transmission is embedded in the surface of one side of the main shell 1 close to the head shell 2, and the transparent ring cover 18 corresponds to the position of the light-emitting circuit board 16, and the transparent ring cover 18 is located on the outermost periphery of the head shell 2, and a main control board 19 for controlling the light-emitting circuit board 16, the battery 4 and the motor 6 is installed on the surface of one side of the main shell 1.

[0025] A circuit board 3 is fixedly installed inside the main shell 1 near the battery 4, an output end of the battery 4 is fixedly connected to an output shaft 61, an external fixed sleeve of the output shaft 61 is connected to a transmission shaft 7, one end of the transmission shaft 7 is fixedly connected to a threaded main rotor 11, the threaded main rotor 11 passes through the outside of the head shell 2, a bearing 12 is sleeved on the outer surface of the threaded main rotor 11 close to the transmission shaft 7, the bearing 12 is limited to rotate inside the head shell 2, an electric grinding rotor 13 is threadedly sleeved on the top of the threaded main rotor 11, the output shaft 61 is sleeved inside the transmission shaft 7, and a bolt 71 is threadedly fixed between the output shaft 61 and the transmission shaft 7, the bolt 71 passes through the inside of the transmission shaft 7 and is threadedly connected to the transmission shaft 7.

[0026] More specifically, in this embodiment, the operator can start the motor 6 and the lighting lamp 17 on the light-emitting circuit board 16 through the main control board 19 at the same time, the battery 4 can provide power support for the motor 6 and the light-emitting circuit board 16, the output shaft 61 of the motor 6 drives the transmission shaft 7 to grind and rotate, the transmission shaft 7 drives the threaded main rotor 11 and the bearing 12 to grind and rotate, the bearing 12 performs limited rotation inside the head shell 2, the threaded main rotor 11 will also drive the electric grinder rotor 13 threadedly sleeved outside the threaded main rotor 11 to grind and rotate, and after the lighting lamp 17 on the light-emitting circuit board 16 emits light, the light source is fed back to the transparent ring cover 18, and the transparent ring cover 18 is used to provide a direct light source in the grinding operation, and the transparent ring cover 18 should have the effect of preventing light from being glaring, so that the operator can see the workpiece clearly in a dimly lit place and while grinding the workpiece through the electric grinder rotor 13, the workpiece can be illuminated by the transparent ring cover 18, thereby effectively ensuring the convenience and practicality of the electric grinder and improving the accuracy of the electric grinder in the grinding state.

[0027] The operator can replace the electric grinder head 13 suitable for grinding operations according to different grinding needs by threading the electric grinder head 13 on the outside of the threaded main rotor 11. The operation method is relatively convenient, and the threaded connection method has strong connection reliability, which not only improves the reliability and stability of electric grinding, but also provides convenience and practicality for replacing the matching grinding head. In addition, the anti-slip sleeve 15 can also be threadedly sleeved on the threaded surface 14 on the outer surface of the head shell 2. When the operator holds the main shell 1 and performs grinding operations, the anti-slip sleeve 15 can provide an anti-wear and anti-slip gripping effect, and the operator can also replace the anti-slip sleeve 15 as needed by threading the anti-slip sleeve 15 on the threaded surface 14 on the outer surface of the head shell 2.

[0028] In addition, in order to improve the connection stability between the output shaft 61 and the transmission shaft 7 , after the output shaft 61 is inserted into the transmission shaft 7 , bolts 71 may be used for threaded fixation.

[0029] Furthermore, a through hole 9 is formed through the surface of one side of the main shell 1 away from the head shell 2, and a locking rod 10 is connected to the inner thread of the through hole 9. A locking hole 8 is formed through the surface of the transmission shaft 7 located between the output shaft 61 and the threaded main rotating head 11, and the top end of one side of the locking rod 10 is adapted to be locked inside the locking hole 8.

[0030] It is worth mentioning that due to the handheld nature of the electric grinder, the operator may accidentally touch it when holding it. Therefore, when the electric grinder is not needed, the locking rod 10 in the through hole 9 can be twisted. After the thread is twisted, the locking rod 10 will gradually approach the transmission shaft 7 until the top of one side of the locking rod 10 is inserted into the locking hole 8 of the transmission shaft 7 to ensure the locking of the transmission shaft 7. In this way, operational injuries caused by accidental touch can be avoided, and the transmission shaft 7 can be locked.

[0031] Embodiment 2, based on the above embodiment:

[0032] Furthermore, a charging plug 5 for charging the battery 4 is fixedly installed on the surface of one end of the main shell 1 away from the head shell 2, and an adjusting lighting button 22, a switch button 20 and an adjusting speed button 21 are installed in sequence on the surface of the main control board 19, and the adjusting lighting button 22 and the adjusting speed button 21 can be adjusted in level by repeatedly pressing, and touch blocks 23 are installed at positions corresponding to the adjusting lighting button 22, the switch button 20 and the adjusting speed button 21 on the circuit board 3, and a power display light group 24 is installed on the same side surface of the circuit board 3 located on the touch block 23, and a slot 25 for a visible power display light group 24 is opened on the surface of the main control board 19.

[0033] More specifically, in this embodiment, the operator can charge the battery 4 by inserting the charging plug 5 into the charging plug. During the charging and use process, the power display light group 24 on the circuit board 3 will display the charging and power usage status. The operator can observe the power through the slot 25 of the main control board 19. On the one hand, the operator can touch the touch block 23 by pressing the switch button 20 on the main control board 19, and then touch the speed adjustment button 21 according to the speed to be polished, and touch the touch block 23 for a second time. The circuit board 3 receives the touch command, controls the motor 6 to start, and rotates and polishes according to the corresponding touch speed. On the other hand, the operator can touch the touch block 23 by pressing the lighting adjustment button 22 on the main control board 19. The circuit board 3 receives the touch command and controls the lighting lamp 17 on the luminous circuit board 16 to emit light. In addition, the lighting adjustment button 22 and the speed adjustment button 21 can only be adjusted according to the number of times they are pressed, ensuring convenience of use.

[0034] Furthermore, two groups of water drop-shaped heat dissipation holes 26 are arranged on one side surface of the main housing 1 .

[0035] Specifically, two groups of heat dissipation holes 26 distributed in a water drop shape on one side of the main shell 1 form heat dissipation holes that are shaped like two "water drop-shaped flowers", which not only have a certain aesthetic effect, but also have a heat dissipation function.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
