[0034] It can be understood that, as Figure 1 , Figure 2 andFigure 3 As shown, the glue shell 100 is in a ring structure, and six insertion slots 101 are arranged on the outer side of the glue shell 100 and uniformly distributed along the ring direction of the glue shell 100. Six outer fixing feet 200 are correspondingly arranged. In use, the outer fixing feet 200 are detachably installed on the outer side of the glue shell 100 through the insertion and connection of the insertion part 210 and the insertion slot 101. Since the outer fixing feet 200 can be replaced relative to the glue shell 100, when facing different models and sizes of machine shells, different outer fixing feet 200 can be replaced through disassembly and assembly to adapt to different machine shells, without the need to replace the entire magnetic ring, thereby improving the adaptability and being suitable for multiple models of products.

[0035] In actual application, the specific structure of the glue shell 100 and the outer fixing feet 200 can be set according to actual use needs, which will not be described in detail here and will be described in detail below.

[0036] In some embodiments, the insertion slot 101 is through from top to bottom, and the insertion part 210 can be inserted into the insertion slot 101 in the top-to-bottom direction. The lower side of the outer fixing foot 200 is provided with a supporting part 220, and the supporting part 220 abuts against the lower side of the glue shell 100. As can be understood, as shown in Figure 1 , Figure 2 and Figure 3 , the supporting part 220 is arranged on the lower side of the insertion part 210, and the insertion slot 101 is through from top to bottom. When the insertion part 210 is completely inserted into the insertion slot 101, the supporting part 220 abuts against the lower side of the glue shell 100. Thus, when the outer fixing foot 200 is connected with the machine shell, the outer fixing foot 200 can support the glue shell 100, which is beneficial to avoid the separation of the outer fixing foot 200 and the glue shell 100, and is convenient to use.

[0037] In some embodiments, the insertion slot 101 is in a "T" type slot structure, and the insertion part 210 is matched with the inner profile of the insertion slot 101. As can be understood, as shown in Figure 1 , Figure 2 and Figure 3 , the horizontal cross-sectional inner profile of the insertion slot 101 is in a "T" shape, and the insertion part 210 is matched with the inner profile of the insertion slot 101, so as to be better matched with the insertion slot 101, avoid loosening, and the "T" type insertion slot 101 is beneficial to limit the movement of the insertion part 210 in the horizontal direction, and ensure stable and reliable connection. In actual application, in addition to the above structure, the insertion slot 101 can also be a dovetail slot structure or an "L" type slot structure, and the specific structure can be set according to actual use needs.

[0038] In some embodiments, the lower side of the insertion slot 101 and / or the upper side of the insertion part 210 is provided with a guide structure for guiding the insertion of the insertion part 210 into the insertion slot 101. As can be understood, as shown in Figure 1 ,Figure 2 and Figure 4 As shown, the guide structure is a chamfer (not shown in the figure) on the upper side of the insertion part 210. The beveled surface of the chamfer helps guide the insertion part 210 into the slot 101, making it easier to use. In practical applications, the guide structure can also be an arc-shaped structure, or it can be set at the lower opening of the slot 101 to facilitate the insertion of the insertion part 210. The specific design can be adjusted according to the actual needs of the application.

[0039] In some embodiments, a release-limiting structure (not shown) is provided between the plug-in portion 210 and the housing 100. The release-limiting structure is used to prevent the plug-in portion 210 from disengaging from the slot 101. It is understood that the release-limiting structure may include a hemispherical elastic protrusion and a corresponding recess. One of the elastic protrusion and the recess is provided on the groove wall of the slot 101, and the other is provided on the plug-in portion 210. When the plug-in portion 210 is inserted into the slot 101, the two compress the elastic protrusion to deform. When it is fully inserted, the elastic protrusion is engaged in the corresponding recess, thereby preventing the plug-in portion 210 from disengaging from the slot 101 and improving the stability and reliability of the connection. In practical applications, in addition to the above-mentioned structure, the release-limiting structure may also include a threaded component. When the insertion part 210 is inserted into the slot 101, the threaded component passes through the insertion part 210 and is threadedly connected to the wall of the slot 101, thereby preventing the insertion part 210 from leaving the slot 101. Alternatively, the release-limiting structure may include a magnetic part provided on the insertion part 210. The magnetic part may be a metal material that can magnetically attract the magnetic tile 400.

The upper shell 110 is located above the lower shell 120 and is connected to the lower shell 120 to form an annular structure of the shell 100. The shell 100 is provided with an annular first mounting space 102 and a plurality of second mounting spaces 103. The plurality of second mounting spaces 103 are evenly spaced along the annular direction of the shell 100, and the plurality of magnetic tiles 400 are respectively installed in the plurality of second mounting spaces 103. By designing the housing 100 as a split structure, during production, the upper housing 110 and lower housing 120 can be injection molded separately. After the upper housing 110 and lower housing 120 cool and solidify, they are then assembled, allowing the magnetic tile 400 and metal ring 300 to be inserted into the housing 100. The magnetic ring can be assembled after the upper housing 110 and lower housing 120 have cooled and solidified. This avoids deformation of the housing 100 due to the temperature of the magnetic tile 400 and metal ring 300, thus improving the product yield. In practical applications, the housing 100 can also be a one-piece injection molded structure, with the metal ring 300 and magnetic tile 400 embedded in the housing 100 during injection molding. The specific structure can be set according to actual usage requirements.

[0043] Furthermore, one of the upper housing 110 and the lower housing 120 is provided with a connecting post 111, and the other is provided with a corresponding connecting hole 121 that is inserted and engaged with the connecting post 111. There are multiple connecting posts 111 and they are evenly spaced along the annular direction of the housing 100. There are multiple connecting holes 121 corresponding to the connecting posts 111.

[0044] Understandably, such as Figure 2 , Figure 3 and Figure 5 As shown, multiple connecting posts 111 are provided on the upper housing 110, and multiple connecting holes 121 are correspondingly provided on the lower housing 120. The multiple connecting posts 111 are evenly spaced along the annular direction of the housing 100, and the multiple connecting holes 121 correspond to the multiple connecting posts 111. When connecting the housing and the lower housing 120, the multiple connecting posts 111 are respectively inserted into the multiple connecting holes 121. This multi-point insertion improves the connection stability between the upper housing 110 and the lower housing 120, facilitating use. In practical applications, the connecting posts 111 can also be located on the lower housing 120, in which case the connecting holes 121 are correspondingly located on the upper housing 110. Besides the above structure, the detachable connection between the upper housing 110 and the lower housing 120 can also be achieved through a snap-fit ​​structure or a threaded structure, depending on the actual usage requirements.
