The specific number and location of the locating pins 110 may allow for determination based on actual requirements.

Referring to fig. 3 and 4, in one embodiment, the stand 200 includes multiple sets, such as four sets, five sets, etc., which may be determined according to practical requirements. The bracket 200 is located at one side of the base plate 100, and the bracket 200 is fixedly connected with the base plate 100. The magnetic ring 500 is sleeved on the bracket 200 to realize connection between the magnetic ring 500 and the bottom plate 100. Specifically, the bracket 200 includes a partition 220 and a support 210, and the support 210 is located at one end of the partition 220. Wherein, the separating parts 220 among the plurality of brackets 200 are fixedly connected, and the magnetic ring 500 is sleeved on the separating parts 220 of the brackets 200. The supporting portion 210 is located on the base plate 100, and the supporting portion 210 is fixedly connected with the base plate 100.

It should be noted that the supporting portion 210 is provided with a supporting surface 201, and the supporting surfaces 201 on adjacent brackets 200 are located on the same horizontal plane. Therefore, the magnetic ring 500 can be effectively ensured to be on the same plane through the supporting surface 201.
