[0035] The clamp unit 2 includes a clamp base 21, the clamp base 21 has a locking portion 22 and a guide portion 23, a locking rod 24 is provided in the guide portion 23, one end of the locking rod 24 is connected with a reset unit 4 through the locking portion 22;

[0036] Among them, the locking portion 22 is provided with a locking unit 5 for positioning the locking rod 24;

[0037] In actual application, the ceramic article to be clamped is placed on the support base 1, and the surface to be polished faces the top, so that the driving unit 3 is started to make the two clamp units 2 approach each other, in the approaching process, the locking rod 24 will contact the surface of the device and present a non-rigid contact, when the clamp unit 2 is moved to the position, the locking unit 5 forms the locking of the locking rod 24, so as to realize the fixing effect of the device.

[0038] Embodiment two

[0039] The deformation-resistant fixing clamp for precision ceramic device grinding provided in embodiment one is further optimized, specifically, as shown in Figure 4 Fig. 2, the surface of the locking portion 22 is provided with a locking groove 220, the locking rod 24 is partially provided in the locking groove 220, the guide portion 23 has a guide groove 230, one end of the locking rod 24 is partially provided in the guide portion 23 through the guide groove 230;

[0040] As Figure 4As shown, the locking unit 5 includes transmission rods 51 evenly distributed on the top of the locking portion 22, and the number of transmission rods 51 in this embodiment is three. The bottom of the transmission rod 51 is fixed with a transmission plate 52. The transmission plate 52 has an arc-shaped locking plate 53 on one side corresponding to the position of the locking groove 220. The arc-shaped locking plate 53 is arranged in the locking groove 220. The arc-shaped locking plate 53 in the locking groove 220 is arranged above the transmission rod 51. The inner side of the arc-shaped locking plate 53 is matched with the surface shape of the transmission rod 51. The arc-shaped locking plate 53 can be in contact with the surface of the transmission rod 51 to form a limiting position under the action of the transmission plate 52.
