The upper two sides of the other right angle side thereof are beveled and chamfered, and the size of the beveled edges and the rounded corners should be such that the rotating plate 304 does not interfere with the adjusting screw 310 and the guide shaft 307 during the rotation process. In order to improve the stability of the adjustment, the angle adjustment mechanism is designed to be two, symmetrically arranged relative to the mounting base plate 305, and respectively connected to the mounting base plate 305, for adjusting the rotation angle of the mounting base plate 305 together.

The retaining spring 303 is fixed in the annular retaining groove to prevent the pin 302 from falling off. The rotating plate 304 is rotatably connected to the positioning base 301 through the pin 302.

[0146] Furthermore, if Figure 7 as well as Figure 8 As shown, a plurality of locking threaded holes 319 are arranged on the rotating plate 304 around its own rotation center circumference. The plurality of locking threaded holes 319 are distributed around the circumference of the center hole on the rotating plate 304.

[0151] Working principle:

[0152] When in use, the first micrometer component 208 and the second micrometer component 214 are rotated respectively, so that the first movable plate 205 and the second movable plate 212 can be moved along the XY direction under the action of the first guide rail 204 and the second guide rail 211 respectively; and thus the initial position of the grinding head 234 can be adjusted. When grinding the crystal block 313, the telescopic driver 220 is extended and the first elastic component 224 is compressed, so that the grinding force is stable and reliable.

[0153] The adjusting screws 310 at both ends of the rotating positioning device 3 can push the clamping block 311 and the shock-absorbing pad 312 fixedly connected thereto to make relative movements, thereby clamping the crystal block 313; under the elastic force of the installed second elastic member 309, the clamping force of the crystal block 313 can be made more stable, and at the same time, it can play a certain buffering role. After the rotating plate 304 is rotated to a certain angle, the screws are inserted through the locking threaded holes 319 of the positioning base 301 and threadedly connected to the rotating plate 304 to fix the rotating plate 304 at this angle.
