[0048] The power tools 100 provided in this application embodiment include, but are not limited to, electric screwdrivers, electric drills, electric wrenches, and electric hammers.

[0049] Please refer to Figures 1 to 6 This application provides an embodiment of an electric tool, which includes a first housing 10, a motor 20, an output shaft 30, a lampshade 40, an optical component 50, and a lighting component 60.

[0050] The motor 20 is housed within the first housing 10, and the output shaft 30 is connected to the motor 20. The output shaft 30 outputs torque and rotates under the driving force of the motor 20, so as to drive the working head to rotate. The working head is detachably connected to the output shaft 30 and is used to act on the work object. For example, the work object is a wall or a cabinet.

[0051] The lampshade 40 is connected to the front end of the first housing 10, which is the end of the first housing 10 closest to the work object. The lampshade 40 is provided with a plurality of first mounting holes 410, which are circumferentially distributed around the axis of the output shaft 30.

[0052] The optical component 50 includes multiple connecting portions 510 and multiple light-transmitting portions 520. The connecting portions 510 are connected between adjacent light-transmitting portions 520, and the light-transmitting portions 520 are connected between adjacent connecting portions 510. The number of light-transmitting portions 520 can be adaptively selected according to the size of the first housing 10 and the lampshade 40, and this embodiment does not specifically limit the number. For example, the number of light-transmitting portions 520 is three, four, five, or six. Figure 5 The image shows the three light-transmitting portions 520 and three connecting portions 510 provided on the optical component 50.

[0053] The optical component 50 and the lampshade 40 are integrally molded by injection molding. Before the integral injection molding, the optical component 50 has already been formed into a single unit. Figure 4 The structure shown allows the optical component 50 to be molded by injection molding, extrusion, or other methods. The optical component 50 has multiple fourth mounting holes 530, which are used to fix the optical component 50 onto the injection mold before integral injection molding, and to inject the lampshade 40 in a fluid state into the mold, so that the optical component 50 is embedded in the lampshade 40 and the light-transmitting part 520 is embedded in the first mounting hole 410.

[0054] The lampshade 40 is made of a first material, and the optical component 50 is made of a second material, wherein the first material and the second material are different materials. In an optional embodiment, the lampshade 40 is formed of a synthetic resin with dispersed coloring material, and the optical component 50 is formed of a synthetic resin. The first material and the second material are not specifically limited; for example, the first material is PA6+GF30, which is a composite material of polyamide 6 (PA6) matrix and 30% glass fiber (GF) reinforcement; the second material is PC (polycarbonate), a colorless and transparent amorphous thermoplastic material.

[0055] The lighting element 60 is positioned corresponding to the light-transmitting portion 520. The light beam emitted by the lighting element 60 can be transmitted through the light-transmitting portion 520 and illuminate the workpiece. The lighting element 60 only needs to emit a light beam; there is no specific limitation. For example, the lighting element 60 is an LED chip 610. Figure 4 The diagram shows adjacent LED beads 610 connected by wires 620 and electrically connected to the battery 80 of the power tool 100, which provides power to the LED beads 610.

[0056] In related technologies, the optical component 50 and the lampshade 40 are integrally injection molded. Because the optical component 50 and the lampshade 40 are made of two different materials, the high-frequency vibration generated during the use of the power tool 100 can easily cause the optical component 50 to loosen.

[0057] Based on this, the power tool 100 provided in this application embodiment has a plurality of first through holes 511 in the connection portion 510 of the optical component 50. During the integrated injection molding process of the optical component 50 and the lamp cover 40, the lamp cover 40 in a fluid state passes through the plurality of first through holes 511 and forms a plug 420 that matches the first through holes 511. The plug 420 is inserted into the first through holes 511 so that the optical component 50 is circumferentially positioned relative to the lamp cover 40, thereby improving the structural stability of the lamp cover 40 and the optical component 50 and greatly reducing the occurrence of the optical component 50 becoming loose due to the high-frequency vibration generated during the operation of the power tool 100.

[0058] In one alternative embodiment, please refer to Figure 4 and Figure 5 Multiple connecting parts 510 and multiple light-transmitting parts 520 form a circular ring structure 5a, and the multiple light-transmitting parts 520 are circumferentially distributed around the axis of the circular ring structure 5a.

[0059] Since the first housing 10 is cylindrical, the multiple connecting parts 510 and the multiple light-transmitting parts 520 form a ring structure 5a, which can better fit the first housing 10; in addition, the optical components 50 of the ring structure 5a can be easily installed, improving installation efficiency.

[0060] Furthermore, the annular structure 5a formed by the multiple connecting parts 510 and the multiple light-transmitting parts 520 of the optical component 50 is a centrally symmetrical shape, which facilitates positioning and installation.

[0061] In one alternative embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The light-transmitting portion 520 protrudes from the surface of the connecting portion 510 and forms a cover structure 521 with a receiving cavity 5211, in which the lighting element 60 is housed. The housing of the lighting element 60 within the receiving cavity 5211 allows the light beam emitted by the lighting element 60 to be focused, ensuring the lighting effect.

[0062] Preferably, the light-transmitting part 520 and the connecting part 510 are integrally injection molded, which not only improves the ease of manufacturing the optical component 50, but also ensures the structural strength of the optical component 50.

[0063] In an optional embodiment, the lighting element 60 is matched with the receiving cavity 5211 of the cover structure 521, which can improve the stability of the lighting element 60 placed in the receiving cavity 5211 of the cover structure 521 and further ensure the lighting effect of the power tool 100.

[0064] In an optional embodiment, the lampshade 40 further includes a light-shielding portion 430 that covers the connecting portion 510. The light-shielding portion 430 not only improves the connection stability between the lampshade 40 and the optical component 50, but also ensures that the light beam emitted by the lighting component 60 only shines through the light-transmitting portion 520, thus guaranteeing the lighting effect of the power tool 100.

[0065] In an alternative embodiment, such as Figure 1 and Figure 2 As shown, the front surface of the light-shielding part 430 and the front surface of the light-transmitting part 520 are located on the same plane, which not only improves the aesthetics of the power tool 100, but also ensures that the light beam transmitted from the light-transmitting part 520 only shines forward, thus guaranteeing the lighting effect.

[0066] Conversely, if the front surface of the light-transmitting part 520 protrudes beyond the front surface of the light-shielding part 430, the light beam transmitted from the light-transmitting part 520 will also be transmitted out from its side, which may affect the lighting effect.

[0067] In an optional embodiment, the first housing 10 is further provided with a plurality of second mounting holes (not shown in the figure), and the lampshade 40 is provided with a plurality of third mounting holes (not shown in the figure) corresponding to the second mounting holes. The power tool 100 also includes a first fastener 70, which is simultaneously inserted into the second mounting holes and the third mounting holes to define the relative positions of the first housing 10 and the lampshade 40.

[0068] The specific structure of the first fastener 70 is not limited in this application embodiment. For example, the first fastener 70 is a bolt 710, and the second mounting hole and the third mounting hole are threaded holes that match the first fastener 70.

[0069] In one alternative embodiment, please refer to Figure 5 The connecting portion 510 is provided with a plurality of clearance portions 512, which are used to avoid the first fastener 70. The clearance portion 512 is a notch 5121 provided in the connecting portion 510. The notch 5121 is much larger than the size of the first fastener 70, so as to avoid the optical component 50 from affecting the connection between the first fastener 70 and the first housing 10 and the lampshade 40.

[0070] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
