In the operation process of the locking plate 9, the first reset spring 10 on the surface of the guide block 8 plays a key role. When the locking plate 9 slides, the guide block 8 moves with the locking plate 9, and the first reset spring 10 will be compressed or reset at the right time. For example, when disassembling, the locking plate 9 slides to compress the first reset spring 10, so that the locking plate 9 is separated from the surface of the second cross block 6; when reinstalling, after the elastic buckle 12 is separated from the ejection hole 14, the first reset spring 10 is reset to make the locking plate 9 inserted into the surface of the second cross block 6.

[0032] The inside of the locking plate 9 is provided with a recess, and the inner wall of the recess is fixedly connected with the second reset spring 11. The surface of the second reset spring 11 is fixedly connected with the elastic buckle 12. In the inside of the locking plate 9, the second reset spring 11 connects the elastic buckle 12. When the locking plate 9 moves, the elastic buckle 12 contacts the surface of the abutting plate 13 under the action of the second reset spring 11.

In the moving process of the locking plate 9, when the elastic buckle 12 reaches the position of the ejection hole 14 under the action of the second reset spring 11, the elastic buckle 12 can smoothly penetrate the ejection hole 14 due to the matching of the two, thereby fixing the position of the locking plate 9.

[0035] The ejection hole 14 is matched with the elastic buckle 12.

[0036] The implementation principle of the ceramic compression ring in the embodiment of the application is as follows: when a person needs to disassemble the compression ring body 3, the person slides the locking plate 9, since the locking plate 9 is connected with the sliding groove 7 through the guide block 8, and the first reset spring 10 is fixedly connected to the surface of the guide block 8 and fixed in the inner wall of the sliding groove 7, when the locking plate 9 is slid, the guide block 8 moves, the first reset spring 10 is compressed, the locking plate 9 is separated from the surface of the second cross block 6, so that the second cross block 6 can be rotated, and in the movement process of the locking plate 9, the elastic buckle 12 connected with the surface of the second reset spring 11 fixedly connected to the inner wall of the recess in the locking plate 9 is in contact with the surface of the resisting plate 13 under the action of the second reset spring 11. When the locking plate 9 moves to a specific position, the elastic buckle 12 reaches the ejection hole 14 on the resisting plate 13, the elastic buckle 12 penetrates through the ejection hole 14 under the reset force of the second reset spring 11, the position of the locking plate 9 is fixed, the person adjusts the angle of the second cross block 6 so that it is aligned with the positioning groove plate 4. Since the first cross block 5 and the second cross block 6 are matched with the positioning groove plate 4, the matching relationship ensures the accuracy of the adjustment. Then the compression ring body 3 is pulled out, the positioning groove plate 4 is separated from the surface of the first cross block 5 and the second cross block 6, when a new compression ring body 3 is installed, the person adjusts the angle of the second cross block 6 on the surface of the first cross block 5 so that it is aligned with the positioning groove plate 4, then the compression ring body 3 is placed into the installation ring groove 2, at this time, the positioning groove plate 4 on the surface of the compression ring body 3 is in contact with the second cross block 6 and the first cross block 5, when the compression ring body 3 is installed to the bottom of the installation ring groove 2, the second cross block 6 is rotated to change the angle thereof, since the first cross block 5 and the second cross block 6 are matched with the positioning groove plate 4, the second cross block 6 after rotation positions the positioning groove plate 4 with the first cross block 5 to prevent separation, the elastic buckle 12 is pressed to separate from the ejection hole 14, since the locking plate 9 is under the action of the first reset spring 10, when the elastic buckle 12 separates from the ejection hole 14, the locking plate 9 is inserted into the surface of the second cross block 6 under the reset of the first reset spring 10, the angle of the second cross block 6 is fixed, and the stability of the installation and positioning of the compression ring body 3 is ensured.
