For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] Power tools (such as slotting machines, angle grinders, etc.) may malfunction during operation. If not discovered in time, it may cause machine damage or safety accidents. Therefore, power tools are usually equipped with fault indicator lights. However, existing power tools usually set the fault indicator lights in the cylindrical part, which will cause blind spots for different user operation methods and machine directions, and the abnormality of the machine cannot be confirmed in time.

[0033] To solve the above technical problems, please refer to Figure 1 and Figure 2 The embodiment of the present application provides an electric tool 100, including: a housing 110, a motor 120 disposed in the housing 110, and a tool head (not shown) driven by the motor 120. The housing 110 is used to mount the motor 120 and the tool head, and the tool head moves (such as rotating, swinging, etc.) under the drive of the motor 120 to achieve the functions of the electric tool 100, such as cutting, grinding, etc.

[0034] Specifically, the housing 110 includes a connected cylindrical portion 111 and a hand-held portion 112, wherein the cylindrical portion 111 has a larger radial dimension and a larger accommodating space inside, which is mainly used to accommodate the components of the power tool 100, and the above-mentioned motor 120 is accommodated in the cylindrical portion 111. The hand-held portion 112 is fixed on the cylindrical portion 111, and its radial dimension is smaller than that of the cylindrical portion 111, mainly providing a gripping portion for the user, so that the user can hold the power tool 100 more conveniently. In this embodiment, the cylindrical portion 111 and the hand-held portion 112 are integrally formed, preferably integrally injection molded. It can be understood that the cylindrical portion 111 and the hand-held portion 112 can be separately provided and relatively fixed by certain methods, such as threaded fixing.

[0035] The handheld portion 112 includes a first handheld portion 1121 and a second handheld portion 1122. The first handheld portion 1121 is disposed on a side of the cylindrical portion 111 away from the tool head. The second handheld portion 1122 is connected to the first handheld portion 1121 and forms an accommodation space with the first handheld portion 1121. The accommodation space is used for the user's hand to pass through to hold the power tool 100. When the power tool 100 is used, the user can selectively hold the first handheld portion 1121 or the second handheld portion 1122, thereby meeting the operation requirements of different users and / or different scenarios.

[0036] The handheld portion 112 further includes a third handheld portion 1123, which is arranged at a certain distance from the first handheld portion 1121 and the second handheld portion 1122, and is relatively close to the tool head. When operating the power tool 100, the user holds the first handheld portion 1121 or the second handheld portion 1122 with one hand and the third handheld portion 1123 with the other hand, so that the power tool 100 can be stably operated.

[0037] In this embodiment, the first hand-held portion 1121 extends approximately in a straight line, and the second hand-held portion 1122 includes a first gripping section and a second gripping section connected to each other. The first gripping section extends approximately in a straight line and the extension direction of the first gripping section is approximately parallel to the extension direction of the first hand-held portion 1121. The angle formed by the second gripping section and the extension direction of the first gripping section is an obtuse angle. The second gripping section is connected to the first gripping section and the first hand-held portion 1121, and the angle formed by the second gripping section and the extension direction of the first hand-held portion 1121 is an acute angle. When the user holds the second hand-held portion 1122, he can choose to hold the first gripping section parallel to the first hand-held portion 1121, or he can choose to hold the second gripping section at an acute angle to the first hand-held portion 1121, or he can choose to hold the connection between the first gripping section and the second gripping section. The user's gripping selectivity is further enriched, and the operation requirements of different users and / or different scenarios are better met. The connection between the first gripping section and the second gripping section and the connection between the second gripping section and the first hand-held portion 1121 are rounded transitions, which can improve the gripping comfort.

[0038] When operating the power tool 100, the user holds the third grip part 1123 with one hand at the front side relatively close to the tool head, and at the rear side relatively far from the tool head, the user can selectively hold the first grip part 1121, the first grip section of the second grip part 1122, the second grip section of the second grip part 1122, and the junction of the first grip section and the second grip section of the second grip part 1122. There are multiple gripping options. When operating the power tool 100, the working angle of the tool head can also be selected in multiple ways. With the horizontal plane as a reference, the power tool 100 can be placed vertically (reference Figure 3 , but not limited to Figure 3 The angle shown in FIG. 1 ) means that the extension plane of the tool head is perpendicular to the horizontal plane; the power tool 100 can also be placed horizontally (reference Figure 4 ), that is, the extension plane of the tool head is parallel to the horizontal plane; it can also be tilted at a certain angle on the basis of vertical or horizontal placement. When operating the power tool 100, there are also multiple options for the height of the tool head relative to the operator, that is, the operator can operate the power tool 100 at different heights, and with the operator's eyes as a reference, the operator can operate it by looking down, looking up, or looking straight. In summary, the power tool 100 of this embodiment has multiple options for holding, the working angle of the tool head, and the operating height. Combining these options provides more options, which can well meet the operating needs of different users and / or different scenarios. The applicant found that with more options, a problem arises, that is, under certain options, the user cannot observe the fault indicator light and cannot confirm the abnormality of the machine in time.

[0039] To solve this problem, the power tool 100 further includes a connection portion 130 and a fault indicator portion 140. The connection portion 130 extends from the end of the second hand-held portion 1122 close to the tool head in a direction toward the cylindrical portion 111 or the first hand-held portion 1121 to connect the second hand-held portion 1122 to the cylindrical portion 111 or the first hand-held portion 1121. The setting of the connection portion 130 strengthens the hand-held portion 112 and increases the bearing force of the hand-held portion 112. The fault indicator portion 140 is used to indicate the working status of the power tool 100. It is set on the side of the connection portion 130 away from the tool head. Please refer to Figures 3 to 5 (but not limited to Figures 3 to 5 With this arrangement, the user can see the fault indicator 140 at any operating angle (not viewed from the tool head position).

[0040] The above-mentioned electric tool 100 connects the second hand-held part 1122 with the cylindrical part 111 or the first hand-held part 1121 by adding a connecting part 130, and at the same time, the fault indicator 140 is arranged on the side of the connecting part 130 away from the tool head. On the one hand, it can support and strengthen the hand-held part 112, and increase the bearing force of the hand-held part 112; on the other hand, when the electric tool 100 is operated, the electric tool 100 is located in front of the operator, and the connecting part 130 is also located in front of the operator. The side of the connecting part 130 away from the tool head just faces the user, and the connecting part 130 is arranged horizontally between the first hand-held part 1121 and the second hand-held part 1122, which can enable the user to see the fault indicator 140 no matter at what operating angle the user holds the first hand-held part 1121 or the second hand-held part 1122, so that the user can observe the working status of the electric tool 100 in real time.

[0041] Figure 1 An embodiment is shown in which both ends of the connecting portion 130 are respectively connected to the second hand-held portion 1122 and the cylindrical portion 111. When the connecting portion 130 is connected to the cylindrical portion 111, preferably, the connecting portion 130 is connected to an area of ​​the cylindrical portion 111 away from the tool head. In this way, dust, mud and water generated by the tool head when the power tool 100 is working will not splash onto the fault indicator portion 140, thereby preventing the fault indicator portion 140 from being covered with mud and dirt, causing the user to be unable to see the alarm status clearly.

[0042] Optionally, in one possible implementation of the present application, please refer to Figure 6The first hand-held portion 1121 extends in the same direction as the cylindrical portion 111, and the extension centerline of the first hand-held portion 1121 is parallel to or coincides with the extension centerline of the cylindrical portion 111. The extension centerlines of the first hand-held portion 1121, the second hand-held portion 1122 and the connecting portion 130 are located in the same extension plane, which is perpendicular to the axis of the output shaft 150 on which the tool head is installed, so that the user can control the processing position of the tool head by adjusting the gripping position and gripping direction.

[0043] It should be noted that the extension centerline mentioned above refers to the central axis of the entity structure in the extension direction, and the extension centerline can be a straight line or a curve, which is specifically determined by the extension path of the entity. Taking the first hand-held portion 1121 as an example, the section of the first hand-held portion 1121 perpendicular to the extension centerline is defined as a cross section, and the first hand-held portion 1121 can be obtained by sweeping the cross section along the extension centerline.

[0044] In this embodiment, the axis of the output shaft 150 of the tool head is perpendicular to the axis of the motor 120 , and the extension plane of the tool head is perpendicular to the axis of the output shaft 150 and parallel to the axis of the motor 120 .

[0045] Furthermore, the axis of the motor 120 is located in the extension plane, so that the motor 120 is coaxially arranged with the cylindrical portion 111, and the center of gravity of the power tool 100 is closer to the extension plane, so that the user can hold and apply force, thereby improving the user experience. And / or, the extension center line of the connecting portion 130 is perpendicular to the axis of the motor 120. The fault indicator 140 can be observed more conveniently.

[0046] Optionally, in one possible implementation of the present application, please refer to Figure 1 The first hand-held portion 1121 and the second hand-held portion 1122 are connected to each other at one end away from the tool head. A switch 160 is provided at the connection between the first hand-held portion 1121 and the second hand-held portion 1122. The switch 160 is used to turn on or off the motor 120.

[0047] The switch 160 is arranged at the connection between the first hand-held part 1121 and the second hand-held part 1122. When the power tool 100 is used, the operator can easily touch the switch 160 regardless of whether the operator chooses to hold the first hand-held part 1121 or the second hand-held part 1122, making the operation of the power tool 100 more convenient. At the same time, the switch 160 can be kept away from the tool head to prevent dust, mud and water generated when the tool head is working from splashing onto the switch 160 and affecting the normal operation of the switch 160.

[0048] Optionally, in an achievable manner of the embodiment of the present application, the housing 110 further comprises a head housing 113, the head housing 113 is connected to one end of the cylindrical portion 111 away from the first hand-held portion 1121, and the output shaft 150 for installing the tool head is partially arranged in the head housing 113 and partially extends out of the head housing 113 to install the tool head. The arrangement of the head housing 113 provides space and protection for the transmission mechanism between the motor 120 and the tool head, and is more convenient for installing the output shaft 150.

[0049] The housing 110 also includes an extension portion 114, a first end of the extension portion 114 is connected to the second hand-held portion 1122, a second end of the extension portion 114 is connected to an end of the cylindrical portion 111 close to the tool head, or, the second end of the extension portion 114 is connected to the head shell 113, or, the second end of the connecting portion 130 is connected to the junction of the cylindrical portion 111 and the head shell 113. Figure 1 and Figure 6 The embodiment shown in FIG. 1 is that the second end of the extension portion 114 is connected to the junction of the cylindrical portion 111 and the head shell 113 .

[0050] As mentioned above, the hand-held portion 112 also includes a third hand-held portion 1123. In this embodiment, the third hand-held portion 1123 is connected to the second end of the extension portion 114. The third hand-held portion 1123 is connected and fixed to the second hand-held portion 1122 through the extension portion 114. The third hand-held portion 1123 serves as an auxiliary handle. As mentioned above, the third hand-held portion 1123 cooperates with the first hand-held portion 1121 or the second hand-held portion 1122 to provide the user with a variety of holding methods, so that the power tool 100 can work in a variety of postures.

[0051] Preferably, the extended midline of the third hand-held portion 1123 is located in the above-mentioned extended plane, and the extended midline of the third hand-held portion 1123 is parallel to the extended midline of the connecting portion 130 , so that the user can hold and observe the fault indicating portion 140 .
