Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0046] Please refer to Figure 1 , Figure 1 This is a front view of a fixture provided in an embodiment of the present application. This embodiment of the present application provides a fixture, comprising: a bracket 1; a first fixing mechanism 2, connected to the bracket 1, having a first fixing through-hole 21 configured to fix a first coating member 22; a second fixing mechanism 3, connected to the bracket 1, having a second fixing through-hole 31 configured to fix a second coating member 32; the axis of the first fixing through-hole 21 and the axis of the second fixing through-hole 31 being arranged at an angle.

[0047] In actual operation scenarios, there are situations where operations need to be performed on different parts of the workpiece to be coated, or there may be an angle between the work surfaces, but the operation trajectory is the same, and multiple operations are required. In the embodiment of the present application, by setting the axes of the first fixed through hole 21 and the second fixed through hole 31 at an angle, the first coating member 22 and the second coating member 32 are also set at an angle, so that operations can be performed on different parts of the workpiece to be coated, or operations can be performed simultaneously on two work surfaces set at an angle, which can effectively reduce the time required for the operation and improve the operation efficiency.

[0048] Please refer to Figure 2 , Figure 2 This is a top view of a fixing fixture provided in an embodiment of the present application. In some embodiments of the present application, the first fixing mechanism 2 includes a first connecting portion 23 and a first fixing portion 24 connected to each other, the first connecting portion 23 also connected to the bracket 1, and the first fixing hole 21 is provided in the first fixing portion 24; and / or the second fixing mechanism 3 includes a second connecting portion and a second fixing portion connected to each other, the second connecting portion also connected to the bracket 1, and the second fixing hole 31 is provided in the second fixing portion.

[0049] In the embodiment of the present application, by connecting the first connecting portion 23 of the first fixing mechanism 2 to the bracket 1 and the first fixing portion 24 to the bracket 1, the effect of the bracket 1 on the operating range of the first coating member 22 is reduced, allowing the first coating member 22 to adapt to a wider range of operating scenarios. The structure and beneficial effects of the second fixing mechanism 3 are similar or identical to those of the first fixing mechanism 2 and will not be further described here.

[0050] Continue to refer Figure 2 In some embodiments of the present application, the first fixing mechanism 2 includes two first fixing parts 24, which are respectively connected to the two ends of the first connecting part 23; and / or the first fixing part 24 is rotatably connected to the first connecting part 23; and / or the second fixing mechanism 3 includes two second fixing parts, which are respectively connected to the two ends of the second connecting part; and / or the second fixing part is rotatably connected to the second connecting part.

[0051] In the embodiment of the present application, the first fixing portion 24 is connected to both ends of the first connecting portion 23, so that two first coating members 22 can be fixed on the first fixing mechanism 2, and the two first coating members 22 can be used for operation at the same time, which helps to improve the operation efficiency. The first fixing portion 24 and the first connecting portion 23 are rotatably connected, so that the first fixing portion 24 can adjust the angle with the first connecting portion 23 according to the operation requirements, thereby adapting to more operation scenarios. The quantitative relationship between the second fixing portion and the second connecting portion and the beneficial effects of the connection relationship are similar or the same as the quantitative relationship between the first fixing portion 24 and the first connecting portion 23 and the beneficial effects of the connection relationship, and will not be repeated here. In addition, the first fixing portion 24 is connected to both ends of the first connecting portion 23, and the two first fixing portions 24 support each other, which helps to reduce the vibration during operation, thereby improving the operation quality and efficiency.

[0052] In some embodiments of the present application, the first coating members 22 fixed by the first fixing portions 24 at both ends of the first connecting portion 23 are identical. For example, when using the fixing fixture provided in the embodiments of the present application to fix two identical first coating members 22, if the operation trajectory needs to be repeated multiple times, the operation trajectory of the two first coating members 22 can be made the same, so that the operation trajectory is repeated twice in the time of one operation, thereby improving the operation efficiency. Alternatively, the first coating members 22 fixed by the first fixing portions 24 at both ends of the first connecting portion 23 are different. For example, one first coating member 22 is coated with a primer and the other first coating member 22 is coated with alcohol. During the operation, the first coating member 22 coated with the primer starts the operation first, and the first coating member 22 coated with the alcohol starts the operation later. Thus, the work content of the original two operations can be completed in the time of one operation.

[0053] In some embodiments of the present application, the first connecting portion 23 is configured to adjust the distance between the first fixing portions 24 at both ends of the first connecting portion 23; and / or the second connecting portion is configured to adjust the distance between the second fixing portions at both ends of the second connecting portion. For example, during operation, the material applied by the first coating member 22 that starts the operation first may need to be left for a certain period of time before it can be covered with other materials. In this case, the distance between the two first coating members 22 can be adjusted according to actual needs so that the difference in the operating time of the two first coating members 22 satisfies the required time for the material applied by the first coating member 22 that starts the operation first.

[0054] In some embodiments of the present application, the first fixing portion 24 and the first connecting portion 23 are connected in a rotational manner, or the second fixing portion and the second connecting portion are connected in a rotational manner, so that the angle between the first coating member 22 and the second coating member 32 can be adjusted to accommodate more operating scenarios. In other embodiments of the present application, the first fixing portion 24 and the first connecting portion 23 are connected in a rotational manner, and the second fixing portion and the second connecting portion are connected in a rotational manner. This not only helps to further enhance the scope of application of the fixing fixture provided by the embodiments of the present application, but also, when adjusting the angle between the first coating member 22 and the second coating member 32, the angles between the first coating member 22, the second coating member 32 and the bracket 1 can also be adjusted, thereby reducing the impact of the bracket 1 on the operating range of the first coating member 22 and the second coating member 32.

[0055] In some embodiments of the present application, the first fixing portion 24 includes a first upper fixing member 241, a first lower fixing member 243 and a first fixing plate 242 clamped between the first upper fixing member 241 and the first lower fixing member 243, and the first fixing through hole 21 passes through the first upper fixing member 241, the first fixing plate 242 and the first lower fixing member 243; and / or, the second fixing portion includes a second upper fixing member, a second lower fixing member and a second fixing plate clamped between the second upper fixing member and the second lower fixing member, and the second fixing through hole 31 passes through the second upper fixing member, the second fixing plate and the second lower fixing member.

[0056] In some embodiments of the present application, the first fixing piece 242 is sandwiched between the first upper fixing member 241 and the first lower fixing member 243, and the first upper fixing member 241, the first fixing piece 242, and the first lower fixing member 243 are used to fix the first coating member 22. This helps to improve the fixing stability of the first coating member 22, thereby facilitating operations using the first coating member 22. The structure and beneficial effects of the second fixing portion are similar or identical to those of the first fixing portion and will not be repeated here.

[0057] Please refer to Figure 2 and Figure 3 , Figure 3This is a rear view of a fixing fixture provided by an embodiment of the present application. In some embodiments of the present application, a first threaded hole 25 is further defined on the first fixing portion 24. The first threaded hole 25 passes through the first upper fixing member 241, the first fixing plate 242, and the first lower fixing member 243, and the axis of the first threaded hole 25 is parallel to the axis of the first fixing through-hole 21. A first bolt 26 is connected to the first threaded hole 25, and the first upper fixing member 241, the first fixing plate 242, and the first lower fixing member 243 are connected by the first bolt 26.

[0058] And / or, a second threaded hole is further provided on the second fixing portion, the second threaded hole passes through the second upper fixing piece, the second fixing plate and the second lower fixing piece, and the axis of the second threaded hole is parallel to the axis of the second fixing through hole 31; a second bolt is connected in the second threaded hole, so that the second upper fixing piece, the second fixing plate and the second lower fixing piece are connected by the second bolt.

[0059] In the embodiment of the present application, a first threaded hole 25 is formed on the first fixing portion 24, passing through the first upper fixing member 241, the first fixing plate 242, and the first lower fixing member 243. A first bolt 26 connected to the first threaded hole 25 is used to connect the first upper fixing member 241, the first fixing plate 242, and the first lower fixing member 243. This allows the first upper fixing member 241, the first fixing plate 242, and the first lower fixing member 243 to be connected as a whole. This helps to better fix the first coating member 22, improves the fixing stability of the first coating member 22, and facilitates operations using the first coating member 22. The beneficial effects of the second threaded hole in the second fixing portion are similar to or identical to the beneficial effects of the first threaded hole 25 in the first fixing portion 24, and will not be repeated here.

[0060] Please refer to Figure 4 , Figure 4 This is a rear view of another fixing tool provided in an embodiment of the present application. In some embodiments of the present application, the first fixing portion 24 further defines a first adjustment hole, the axis of the first adjustment hole being at an angle to the axis of the first fixing through hole 21, and the first adjustment hole being in communication with the first fixing through hole 21. A first adjustment rod 27 is connected to the first adjustment hole, and the first adjustment rod 27 is configured to abut against the first coating member 22 to secure the first coating member 22 in the first fixing through hole 21.

[0061] And / or, a second adjustment hole is also provided on the second fixing portion, the axis of the second adjustment hole has an angle with the axis of the second fixing through hole 31, and the second adjustment hole is connected to the second fixing through hole 31; a second adjustment rod is connected to the second adjustment hole, and the second adjustment rod is configured to abut against the second coating member 32 to fix the second coating member 32 in the second fixing through hole 31.

[0062] In an embodiment of the present application, a first adjustment hole is opened on the first fixing portion 24, and the first coating member 22 is fixed by using a first adjustment rod 27 connected to the first adjustment hole, thereby further fixing the first coating member 22, improving the fixing stability of the first coating member 22, and facilitating operations using the first coating member 22. In addition, the first adjustment rod 27 can rotate within the first adjustment hole, so that the position of the first adjustment rod 27 can be adjusted according to the specific size of the first coating member 22 being fixed, thereby making the applicable scope of the fixing fixture provided by the embodiment of the present application wider. The structure and beneficial effects of the second fixing portion are similar or identical to the structure and beneficial effects of the first fixing portion 24, and will not be repeated here. For example, the axis of the first adjustment hole is perpendicular to the axis of the first fixed through hole 21.

[0063] In some embodiments of the present application, the first connecting portion 23 includes a first limiting member, the first limiting member is connected to the first fixing portion 24, and the first limiting member is configured to limit the rotation of the first fixing portion 24; and / or, the second connecting portion includes a second limiting member, the second limiting member is connected to the second fixing portion, and the second limiting member is configured to limit the rotation of the second fixing portion.

[0064] In this embodiment, a first stopper is provided between the first connecting portion 23 and the first fixing portion 24. After determining the angle between the first connecting portion 23 and the first fixing portion 24, the first stopper can be used to limit the rotation of the first fixing portion 24, thereby fixing the angle between the first connecting portion 23 and the first fixing portion 24. This prevents the first coating member 22 from rotating during the coating operation and affecting the operation. The structure and beneficial effects of the second connecting portion are similar or identical to those of the first connecting portion 23 and are not further described here.

[0065] Please refer to Figure 5 , Figure 5 This is a front view of another fixing tool provided in an embodiment of the present application.

The bracket 1 includes a plurality of first brackets 10 spaced apart, and the first fixing mechanism 2 and the second fixing mechanism 3 are connected to the plurality of first brackets 10. This helps to improve the connection stability between the first fixing mechanism 2, the second fixing mechanism 3, and the bracket 1. A plurality of connecting through-holes 101 are provided on the first bracket 10, and the first fixing mechanism 2 and the second fixing mechanism 3 are connected to the first bracket 10 via the connecting through-holes 101. The connecting through-holes 101 can be used to adjust the position of the first fixing mechanism 2 and / or the second fixing mechanism 3 to accommodate a variety of operating scenarios.

[0068] In this embodiment, a first chute 102 is provided on the first bracket 10, and a first slider 104 is disposed within the first chute 102. The first connecting portion 23 is connected to the first slider 104, so that the first connecting portion 23 can slide within the first chute 102, thereby adjusting the position of the first coating member 22 to accommodate a variety of operating scenarios. The beneficial effects of the connection relationship between the second chute 103, the second slider, and the second connecting portion are similar or identical to the beneficial effects of the connection relationship between the first connecting portion 23, the first chute 102, and the first slider 104, and will not be repeated here.
