A connecting sleeve 37 is provided on the drilled positioning ring 34, a sliding head 38 is provided on the upper part of the elastic positioning pin 35, the lower end of the elastic positioning pin 35 is in a conical structure, the elastic positioning pin 35 penetrates through the drilled positioning ring 34, the sliding head 38 is slidably installed in the connecting sleeve 37, a buffer spring 39 is installed in the connecting sleeve 37, an end cover 40 is connected to the upper end of the connecting sleeve 37, and the buffer spring 39 abuts between the sliding head 38 and the end cover 40.

[0062] When the large quartz ring 3 is processed, a hole needs to be drilled in the side wall, and the drilling position corresponds to the counterbore 36 on the upper end surface of the large quartz ring 3. Through the arrangement of the drilled positioning ring 34, the circumferential position of the large quartz ring 3 is positioned, which facilitates the accuracy of the subsequent drilling position. The other structures are the same as any one of embodiments 1 to 3.

[0063] The above-mentioned embodiments are only the preferred schemes of the present application, and do not limit the present application in any form, and other variants and modifications can be made without departing from the technical scheme recited in the claims.
