Description

Technical Field

[0001] The present application relates to the field of industrial technology, and in particular to a supporting device. Background Art

[0002] With the development of electric technology, a variety of power tools have emerged on the market, such as tappers, electric screwdrivers, and electric drills. These power tools are widely used in a variety of fields, including machining, automotive manufacturing, aerospace, construction, and electronics. The main function of a tapper is to use a tap to cut a hole in a workpiece to form a thread; the main function of an electric screwdriver is to tighten and loosen screws, and an electric drill is mainly used to drill holes in various materials.

[0003] However, various safety hazards may arise during the actual use of power tools. For example, when manually operating a tapping machine, operators need to directly contact or be close to the high-speed rotating tap, which can easily cause hand injuries or cuts. Another example is that if the tap breaks and debris is thrown during the tapping process, it can cause serious harm to the user. Therefore, how to improve the safety of power tools is an urgent issue that needs to be addressed. Utility Model Content

[0004] The present application provides a support device for improving the safety performance of an electric tool.

[0005] In a first aspect, the present application provides an electric tool, comprising: a first structure for being spliced with the electric tool; a supporting structure connected to the first structure to form a first channel; wherein a first tool accessory clamped by the electric tool can move within the first channel.

[0006] In the embodiment of the present application, the power tool may be, for example, at least one of a tapping machine, an electric screwdriver, or an electric drill. The first tool accessory may be understood as a tool head currently installed on the power tool, such as a tap or a drill bit.

[0007] In the technical solution of the present application, the support structure and the first structure in the support device are connected to form a first channel, and then when the first structure is spliced with the power tool, the first tool accessory clamped by the power tool can move within the first channel. In this way, when the user uses the power tool, the user can avoid direct contact with or proximity to the first tool accessory, thereby effectively improving the safety performance of the power tool. For example, taking a tapping machine as an example of the power tool and a tap as an example of the first tool accessory, when the user manually operates the tapping machine, due to the contact between the support device and the workpiece surface, the tap moves in the first channel formed by the support device, which can avoid the situation where the tap breaks and causes injury to the user's hand, and can also avoid the situation where debris from the broken tap is thrown out and causes injury to the user.

[0008] Optionally, the first channel includes N channels, the first tool accessories include M tool accessories, and the first groove includes N grooves; wherein N is a positive integer greater than or equal to 1, and N is greater than or equal to M. In this way, the power tool can use M tool accessories to process the workpiece simultaneously, thereby effectively improving the working efficiency of the power tool.

[0009] In one possible design, when the support structure is in contact with the workpiece surface, the first tool accessory is perpendicular to the workpiece surface. In this design, when the support structure in the support device is in contact with the workpiece surface, the first tool accessory can be made perpendicular to the workpiece surface, thereby effectively improving the verticality and concentricity of the first tool accessory in processing the workpiece, thereby effectively improving the working performance of the power tool. For example, taking a tapping machine as an example of the power tool and a tap as an example of the first tool accessory, the technical solution of the present application can improve the verticality and concentricity of the tap in processing the workpiece, reduce the probability of the tap breaking during the processing, and thereby enable the tapping machine to tap small threads with smaller diameters. In addition, when the first component is in contact with the workpiece surface, the verticality and concentricity of the first tool accessory in processing the workpiece can be improved, thereby improving the tapping quality and tapping success rate of the tapping machine.

[0010] In one possible design, the support device includes a support structure, wherein the support structure includes N points where the support device contacts the workpiece surface. In this design, the support device includes a support structure that improves the stability of the support device when in contact with the workpiece surface, thereby ensuring that the first tool attachment and the workpiece surface remain stably perpendicular.

[0011] In one possible design, the support device includes a telescopic structure, which is disposed within the support structure, or the first structure is connected to the support structure to form the telescopic structure. The length of the support device is related to the connection between the first structure and the support structure. In this design, the length of the support device is adjustable. When the first structure in the support device is coupled to the power tool, the depth of the workpiece processed by the first tool accessory held by the power tool can be adjusted by adjusting the length of the support device. Furthermore, this design provides multiple implementations of the telescopic structure.

[0012] In one possible design, the relative angle between the first structure and the support structure is adjustable. In this design, the relative angle between the first structure and the support structure is adjustable, so that the angle of the contact surface between the support device and the workpiece can be adjusted, allowing the user to process the workpiece at a desired angle, thereby meeting the user's diverse processing needs.

[0013] In a possible design, the side of the support device can be a transparent material or a non-transparent material, and the transparent material can be a translucent material and / or a fully transparent material. In this design, the support device is set to a transparent material to facilitate the user to observe the working conditions.

[0014] In a possible design, the contact surface between the support device and the workpiece surface is provided with an anti-slip rubber pad. In this design, damage to the workpiece surface caused by the support device can be reduced.

[0015] In one possible design, the side of the support device has any one of a closed structure, an open-close structure, or an open structure. In this design, the side of the support device is configured as a closed structure to prevent machining debris from splashing; alternatively, the side of the support device is configured as an open-close structure to flexibly control the support device to form an open or closed structure, facilitating the cleaning of machining debris from the support device; alternatively, the side of the support device is configured as an open structure to facilitate the user's observation of the machining status.

[0016] In a possible design, the opening and closing structure forms an opening or a closing opening under the control of the electric tool.

[0017] In one possible design, the first structure is connected to the power tool by: a magnet provided on the first surface of the power tool, the first structure being connected to the power tool via the magnet; and / or a snap-fit structure provided on the first surface of the power tool, the first structure being connected to the power tool via the snap-fit structure. Alternatively, the first structure is connected to the power tool by a magnet provided on the first surface; and / or a snap-fit structure provided on the first surface of the first structure, the first structure being connected to the power tool via the snap-fit structure. This design provides multiple ways to connect the support device to the power tool. BRIEF DESCRIPTION OF THE DRAWINGS

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The present application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] See Figure 1 , Figure 1 This application provides one of the possible structural diagrams of a support device. Figure 1 As shown in (a), the supporting device 100 includes a first structure 101 and a supporting structure 102, and the supporting structure 102 is connected to the first structure 101 to form a Figure 1 The first channel 103 shown in (b).

[0036] like Figure 2 As shown, the first structure 101 can be spliced with the power tool 200 , and the first tool accessory 300 clamped by the power tool 200 can move within the first channel 103 of the supporting device 100 .

[0037] Optionally, the first channel 103 includes N channels, the first tool attachment 300 includes M tool attachments, and the first groove includes N grooves, where N is a positive integer greater than or equal to 1, and N is greater than or equal to M. In this way, the power tool can use M tool attachments to process a workpiece simultaneously, thereby effectively improving the working efficiency of the power tool.

[0038] In the embodiment of the present application, the power tool 200 may be, for example, at least one of a tapping machine, an electric screwdriver, or an electric drill. The first tool accessory 300 may be understood as a tool head currently installed on the power tool 200, such as a tap or a drill.

[0039] In the technical solution of the present application, the support structure 102 and the first structure 101 in the support device 100 are connected to form a first channel. When the first structure 101 is connected to the power tool 200, the first tool accessory 300 held by the power tool 200 can move within the first channel. In this way, when the user uses the power tool 200, the user can avoid direct contact with or proximity to the first tool accessory 300, thereby effectively improving the safety performance of the power tool 200. For example, the power tool 200 is a tapping machine, and the first tool accessory 300 is a tap. When the user manually operates the tapping machine, the support device 100 contacts the surface of the workpiece, and the tap moves within the first channel 103 formed by the support device 100. This can prevent the tap from breaking and causing injury to the user's hand, and can also prevent the workpiece from being thrown out by the high-speed rotating tap due to insecure fixation and causing injury to the user.

[0040] See Figure 3 When the support structure 102 contacts the workpiece surface, the first tool attachment 300 is perpendicular to the workpiece surface. In other words, when the support structure 102 in the support device 100 contacts the workpiece surface, the first tool attachment 300 can be perpendicular to the workpiece surface, thereby effectively improving the perpendicularity and concentricity of the workpiece processed by the first tool attachment 300, thereby effectively improving the working performance of the power tool 200. For example, if the power tool 200 is a tapping machine and the first tool attachment 300 is a tap, the technical solution of the present application can improve the perpendicularity and concentricity of the tap processing on the workpiece, thereby enabling the tapping machine to produce small threads with smaller diameters, and improving the tapping quality and tapping success rate of the tapping machine.

[0041] In the embodiments of this application, Figure 1 The first structure 101 and the supporting structure 102 of the supporting device 100 are merely examples. The first structure 101 and the supporting structure 102 can be implemented in various forms, and the present embodiment does not impose any specific limitations thereto.

[0042] In the embodiment of the present application, the support structure 102 includes N points where the support device 100 contacts the surface of the workpiece.

[0043] Example 1, the support structure 102 is as follows Figure 1 As shown in (b), the bottom of the support structure 102 may be provided with a reinforcing rib structure. The bottom of the support structure 102 is the surface in contact with the workpiece surface, and the N points where the support device 100 contacts the workpiece surface are the reinforcing rib structure.

[0044] Example 2, the support structure 102 may be as follows Figure 3 The three supporting legs shown are in contact with the workpiece surface. The N points where the supporting device 100 contacts the workpiece surface are the three points where the three supporting legs contact the workpiece surface.

[0045] Optionally, the support device 100 may also have a telescopic structure. This allows the length of the support device 100 to be adjustable, and the depth of the workpiece processed by the first tool attachment 300 can be adjusted by adjusting the length of the support device 100. In the embodiment of the present application, the telescopic structure of the support device 100 can be implemented in a variety of ways, including but not limited to the following:

[0046] In mode 1, the telescopic structure of the supporting device 100 is provided in the supporting structure of the supporting device 100 .

[0047] For example, see Figure 4 The support structure of the support device 100 includes a support structure 102A and a support structure 102B, each of which is provided with a telescopic structure 1021. Thus, by adjusting the telescopic length of the telescopic structure 1021, the length of the support structure 102A and the support structure 102B can be adjusted, thereby adjusting the length of the support device 100, thereby adjusting the processing depth of the workpiece by the first tool attachment 300.

[0048] In a second embodiment, the first structure and the support structure are connected to form a telescopic structure, and the length of the support device is related to the connection between the first structure and the support structure. Thus, by adjusting the connection between the first structure and the support structure, and thereby adjusting the length of the support device, the depth of the workpiece processed by the first tool attachment 300 can be adjusted.

[0049] For example, please see Figure 5 The support device 100 includes a first structure 101 and a support structure 102. The first structure 101 and the support structure 102 are connected to form a telescopic structure of the support device 100. By adjusting the connection position of the first structure 101 and the support structure 102, the length of the support device 100 can be adjusted, thereby adjusting the depth of the workpiece processed by the first tool attachment 300. Figure 5 As shown in (a), the first structure 101 and the support structure 102 are connected at a first position in the axial direction of the housing 101, and the length of the support device 100 is 1; Figure 5 As shown in (b), the first structure 101 and the supporting structure 102 are connected at the second position in the axial direction of the shell 101, and the length of the supporting device 100 is length 2. When the supporting device contacts the surface of the workpiece, the surface distance of the first position relative to the workpiece is length 1, and the surface distance of the second position relative to the workpiece is length 2. When the first position is higher than the second position, the length 1 is greater than the length 2.

[0050] Optionally, the relative angle between the first structure 101 and the support structure 102 is adjustable. Thus, by adjusting the relative angle between the first structure 101 and the support structure 102, the angle of the contact surface between the support device 100 and the workpiece can be adjusted, so that the user can process the workpiece at the angle required by the user, thereby meeting the user's diverse processing needs. For example, please continue to refer to Figure 5 As shown in (c), by rotating the support structure 102, the relative angle between the first structure 101 and the support structure 102 can be adjusted, and then the angle of the contact surface of the support device 100 relative to the workpiece can be adjusted, so that the user can use the power tool 1000 to drill holes obliquely on the workpiece.

[0051] Optionally, the side of the support device 100 can be made of a transparent material or a non-transparent material. The transparent material can be a semi-transparent material and / or a fully transparent material, which is not specifically limited in the present embodiment. In this way, the support device 100 is set to a transparent material to facilitate the user to observe the working conditions.

[0052] Optionally, a non-slip rubber pad may be provided on the contact surface between the support device 100 and the workpiece surface, thereby reducing damage to the workpiece surface caused by the support device 100 .

[0053] In one possible embodiment, the side of the support device 100 can be any one of a closed structure, an open-closed structure, or an open structure. Thus, by setting the side of the support device 100 to a closed structure, it is possible to prevent processing debris from splashing; alternatively, by setting the side of the support device 100 to an open-closed structure, the support device 100 can be flexibly controlled to form an open structure or a closed structure, making it easier to clean processing debris from the support device 100; alternatively, by setting the side of the support device 100 to an open structure, it is possible to facilitate the user to observe the processing status. For example, see Figure 6 , the side surface of the supporting device 100 may include Figure 6 The opening and closing structure 1022a shown in (a) of FIG; The side of the supporting device 100 may include Figure 6 The side of the supporting device 100 may include the opening structure 1022b shown in (b) Figure 6 The opening and closing structure 1022c shown in (c) in FIG.

[0054] Optionally, the power tool 200 may further include a controller that can control the opening and closing structure to open or close when the side of the support device 100 is in the open and close structure. In this way, the support device 100 can be adapted to different processing conditions. For example, when the first tool attachment 300 is processing a workpiece, the controller can control Figure 6The opening and closing structure 1022c shown in (c) is closed to form a closed structure; after the first tool attachment 300 completes processing of the workpiece, the controller can control Figure 6 The opening and closing structure 1022c shown in (c) is opened to form an opening structure, which is convenient for the user to clean processing debris.

[0055] In the embodiment of the present application, there are many ways to splice the first structure 101 and the power tool 200, including but not limited to the following implementations:

[0056] In embodiment 1, a magnet is provided on the first surface of the power tool 200, and accordingly, the first structure 101 is connected to the power tool 200 via the magnet. The shape of the magnet and the position of the magnet on the first surface of the power tool 200 are not limited in this embodiment.

[0057] In embodiment 2, a snap-fit structure is provided on the first surface of the power tool 200, and accordingly, the support device 200 is spliced with the power tool 200 via the snap-fit mechanism. The position of the snap-fit structure on the first surface of the power tool 200 is not limited in this embodiment.

[0058] In embodiment 3, a magnet is provided on the first surface of the first structure 101, and accordingly, the first structure 101 is spliced with the first structure 101 via the magnet. The shape of the magnet and the position of the magnet on the first surface of the first structure 101 are not limited in this embodiment.

[0059] In embodiment 4, a snap-fit structure is provided on the first surface of the first structure 101, and accordingly, the support device 200 is spliced with the first structure 101 via the snap-fit mechanism. The position of the snap-fit structure on the first surface of the first structure 101 is not limited in this embodiment.

[0060] The above-mentioned Embodiments 1 to 4 can be used in combination or individually.

[0061] For example, Figure 7 As shown, the first structure 101 of the supporting device 100 includes a groove 101a and a snap-fit structure 101b; the groove 101a can be provided with a magnet, which can magnetically attract the metal in the power tool 200, and the snap-fit structure 101b can be coupled with the snap-fit structure in the power tool 1000, so that the supporting device 100 and the power tool 200 are spliced.
