[0047] Impact wrenches or impact screwdrivers are widely used because of their small reaction torque on the operator during operation. This type of power tool 100 is used to transmit the rotational force of the motor in the housing to the tip tool to rotate the tip tool holding part and the tip tool, such as mounting a drill bit on the tool holding part. The power tool 100 can drive and perform the required work, such as tightening a screw.

[0048] When working in a dark place where light cannot reach, such as an attic or the floor of a house, the work environment makes the operability poor and the accuracy poor. Therefore, it is necessary to install a lamp on the housing of the power tool 100, and use the lamp to light and illuminate parts such as tip tools or screws. However, the lamp and lampshade of the existing lighting device are an integrated structure. When the lamp or the lampshade is damaged, it needs to be replaced as a whole. Therefore, the existing power tool 100 has the problem of inconvenient maintenance and replacement of the lighting device.

[0049] In order to solve the above problems, the present application relates to an electric tool 100, which includes a housing, a motor, a holding component 4, a transmission mechanism, a cover body 5 and a lighting assembly 6. The housing includes a first housing 1, and a protrusion 11 is provided on the first housing 1. The motor is arranged inside the housing. The holding component 4 is arranged inside the protrusion 11, and the holding component 4 is used to hold the end tool. The transmission mechanism is arranged inside the housing, and the transmission mechanism is used to transmit the driving force generated by the motor to the holding component 4. The cover body 5 has a mounting portion 52 and a fixing groove 51, the mounting portion 52 is sleeved on the protrusion 11, and the fixing groove 51 is provided with a light-transmitting portion 512. The lighting assembly 6 is accommodated in the fixing groove 51, and generates light passing through the light-transmitting portion 512.

[0050] The electric tool 100 described in the present application is provided with a housing, a motor, a holding component 4 and a transmission mechanism, so that the electric tool 100 can drive the holding component 4 to rotate and cooperate with the cutting-edge tool to complete the corresponding work. At the same time, by providing a raised portion 11 on the housing to cooperate with the installation and fixation of the cover body 5 and the lighting tool, the normal operation of the electric tool 100 in a dark environment can be effectively guaranteed. The present application fixes the lighting tool on the fixing groove 51 of the cover body 5 so that it can be installed on the raised portion 11 of the housing along with the cover body 5, which helps to reduce the difficulty of installing the lighting tool, thereby facilitating the maintenance and replacement of the lighting tool.

[0051] Based on the above overall design concept, an exemplary structure of the electric tool 100 of this embodiment is as follows: Figure 1-Figure 4 As shown, this embodiment also specifically takes an electric screwdriver as an example to introduce the electric tool 100. However, in addition to being an electric screwdriver, the electric tool 100 of this embodiment can also be other types of electric tools 100. And when it is other types of electric tools 100, its specific structure can refer to the following description of this embodiment.

[0052] Specifically, the housing of the electric tool 100 includes a first housing 1 and a second housing 2. The second housing 2 is formed with a handle for the user to hold, and the above-mentioned motor and transmission mechanism are both arranged inside the second housing 2, and the motor and transmission mechanism are both indicated in the figure. In addition, other components such as batteries or controllers may also be arranged inside the second housing 2, so that the electric tool 100 can be used portable. In this embodiment, the first housing 1 is arranged at the front end of the second housing 2, and the above-mentioned retaining component 4 is arranged inside the first housing 1. The motor is configured to generate a driving force and transmit the driving force to the retaining component 4 through a transmission mechanism, that is, the retaining component 4 is transmission-connected to the output end of the motor through the transmission mechanism. At the same time, the retaining component 4 is used to install a cutting-edge tool.

[0053] like Figure 1 and Figure 4 As shown, the first housing 1 has a mounting surface 12, and a plurality of first mounting holes 13 are arranged on the mounting surface 12. The first housing 1 and the second housing 2 are fixed together by connecting members 3 passing through the first mounting holes 13. Preferably, the number of the first mounting holes 13 is four, and the four first mounting holes 13 are arranged around the raised portion 11 of the first housing 1 at intervals. The connecting members 3 are arranged as screws, which helps to ensure the fixing effect of the first housing 1 and reduce the difficulty of its installation.

[0054] At this time, a protrusion 11 is provided on the mounting surface 12, and a receiving cavity is provided inside the protrusion 11 for accommodating the retaining component 4. In this embodiment, the protrusion 11 is provided as a cylindrical structure, and the cover body 5 is sleeved and fixed on the outer circumference of the protrusion 11, and at this time, the cover body 5 covers the above-mentioned mounting surface 12. Figure 3 As shown, the cover body 5 has a fixing groove 51. When the cover body 5 is sleeved on the raised portion 11, the fixing groove 51 cooperates with the mounting surface 12 to form a receiving space, and at this time, the lighting assembly 6 is received in the receiving space. Preferably, the lighting assembly 6 is arranged on the fixing groove 51 and received in the receiving space as the cover body 5 is fixed. Such an arrangement makes the lighting assembly and the cover body a split connection structure, which helps to reduce the maintenance difficulty and maintenance cost of the power tool 100.

[0055] It should be understood that the cover body 5 has a mounting portion 52 adapted to the raised portion 11. Specifically, a clamping member 8 is provided on the outer peripheral surface of the raised portion 11, and a limiting groove 521 is provided on the mounting portion 52, and the clamping member 8 is movably adapted to the limiting groove 521. Figure 2 As shown, the limiting groove 521 is set as an L-shaped structure. When the mounting portion 52 is sleeved on the outer peripheral surface of the protruding portion 11, the clamping member 8 is inserted into the limiting groove 521, and then the clamping member 8 can be accommodated in the limiting groove 521 by rotating the cover body 5. At this time, the limiting groove 521 can prevent the clamping member 8 from being separated from the limiting groove 521, thereby realizing the clamping fixation of the mounting portion 52 and the protruding portion 11, thereby ensuring the detachable installation of the cover body 5 on the first shell 1. In this embodiment, when the mounting portion 52 is sleeved on the outer peripheral surface of the protruding portion 11, the cover body 5 can rotate with the protruding portion 11 as the center. Due to the setting of the limiting groove 521, the rotation angle of the cover body 5 is 10° to 25°. Preferably, the rotation angle is set to 15°.

[0056] It should be further understood that the number of the above-mentioned clamping parts 8 is multiple, and the multiple clamping parts 8 are arranged on the outer peripheral surface of the protrusion 11 and are arranged at intervals along the circumference of the protrusion 11. In this embodiment, the number of the clamping parts 8 is three. Preferably, the clamping part 8 is set as a square convex column integrally formed with the protrusion 11. Such a setting helps to reduce the processing difficulty of the power tool 100, and at the same time, it also helps to further improve the limiting effect of the clamping part 8 in the limiting groove 521, thereby ensuring the installation effect of the cover body 5.

[0057] Here, it should be noted that the protrusion 11 and the mounting portion 52 may also be mounted in coordination with each other in other ways and fixed by means of snap connections or screw connections, but the installation process of the above structure is relatively simple and has a good fixing effect.

[0058] like Figure 3As shown, the fixing groove 51 is set as an annular groove, and the annular groove is arranged around the mounting portion 52. At the same time, a light-transmitting portion 512 is set in the fixing groove 51. By setting the fixing groove 51 as an annular groove and cooperating with the light-transmitting portion 512, it is possible to effectively cooperate with the lighting assembly 6 and form an irradiation light source surrounding the holding assembly, which helps to improve the lighting effect of the lighting assembly 6 and ensure its light intensity in a dark environment, thereby helping to improve the use effect of the power tool 100.

[0059] At this time, the lighting assembly 6 includes a circuit board 61 and an LED lamp 62, wherein the circuit board 61 is configured as a ring structure. There are multiple LED lamps 62, and the multiple LED lamps 62 are arranged at intervals on the circuit board 61. By configuring the circuit board 61 as a ring structure, it can be effectively installed with the fixing groove 51, and the configuration of multiple LED lamps 62 helps to improve the installation efficiency of the LED lamp 62 and ensure the use effect of the LED lamp 62.

[0060] In this embodiment, the circuit board 61 is detachably arranged in the fixing groove 51. The circuit board 61 can be installed in the fixing groove 51 by means of a clamp or screw connection, and the circuit board 61 and the fixing groove 51 are detachably connected. When the circuit board 61 or the LED is damaged, the lighting assembly 6 can be repaired or replaced by means of replacement or repair, which helps to reduce the difficulty of replacing the lighting assembly 6 and can effectively reduce the maintenance cost of the power tool 100.

[0061] like Figure 2 and Figure 3 As shown, the lighting assembly 6 further includes a screw connection 7, and the number of the screw connection 7 is multiple, and the multiple screw connection 7 is used to fix the circuit board 61 in the fixing groove 51. Specifically, a fixing hole 511 is provided in the fixing groove 51, and a second mounting hole 611 is provided on the circuit board 61. At the same time, a screw connection 7 that can pass through the second mounting hole 611 and be screwed on the fixing hole 511 is provided to fix the circuit board 61 in the fixing groove 51. Such a configuration further reduces the difficulty of installing the circuit board 61 and the LED, improves the installation effect of the lighting assembly 6, and further helps to reduce the efficiency of repairing and replacing the lighting assembly 6.

[0062] At this time, the first housing 1 is provided with a relief hole 121, and the relief hole 121 is provided in a one-to-one correspondence with the screw connection member 7. Figure 2As shown, a avoidance hole 121 is provided on the mounting surface 12. When the cover body 5 is mounted on the raised portion 11, the avoidance holes 121 are provided in one-to-one correspondence with the screw connectors 7. In this embodiment, the number of the screw connectors 7 is three, and accordingly, the number of the avoidance holes 121 is three. The avoidance holes 121 can prevent the screw connector 7 from abutting against the mounting surface 12, and when the screw connector 7 is loose, the screw connector 7 can be effectively prevented from being separated from the fixing hole 511, thereby improving the fixing effect of the cover body 5 and the lighting assembly 6.

[0063] like Figure 2 and Figure 3 As shown, the light-transmitting portion 512 is a through hole provided on the cover body 5, and the through hole is provided corresponding to the LED lamp 62. The light-transmitting portion 512 is provided as a through hole and provided corresponding to the LED lamp 62, which can effectively ensure the irradiation effect of the LED lamp 62 and reduce the processing difficulty of the cover body 5. Of course, in addition to this, the light-transmitting portion 512 can also be provided as a transparent material such as glass or plastic, which is not limited here.

[0064] At this time, the cover body 5 is also provided with a wire outlet protection portion 53, and the wire outlet protection portion 53 has at least one wire outlet groove 531. Figure 1-Figure 3 As shown, a wire outlet protection portion 53 is provided at the bottom of the cover body 5. When the cover body 5 is mounted on the protrusion 11 and is rotated and fixed on the protrusion 11, the wire outlet protection portion 53 is located directly below the retaining member 4. In this embodiment, the number of wire outlet grooves 531 is two, and at the same time, a wiring hole 14 is provided on the first housing 1. The wiring hole 14 cooperates with the two wire outlet grooves 531 on the wire outlet protection portion 53 to effectively ensure the power supply of the circuit board 61 and the LED lamp 62.

[0065] In addition, the electric tool 100 further includes a protective cover 9, which is covered on the cover body 5. In this embodiment, the protective cover 9 is a rubber member, which is wrapped on the cover body 5. The protective cover 9 can effectively prevent the electric tool 100 from damaging the cover body 5 when working, and at the same time, it also helps to deepen the depth of the light-transmitting portion 512, thereby reducing the situation where dust or other impurities enter the accommodating space to damage the lighting assembly 6.

[0066] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
