The inside of the retaining rings 3 is provided with snap-fit ​​grooves 10, and the buckles 9 are located inside the snap-fit ​​grooves 10. One side of the snap-fit ​​grooves 10 is provided with fixing rings 7, and the two ends of the fixing rings 7 are respectively installed with fixing parts 4.

[0020] The main body 1 has an internal slot 2 for inserting a retaining ring 3. A diaphragm plate 6 is installed on the inner wall of the retaining ring 3. The retaining ring 3 is inserted into the slot 2 from the top of the main body 1, so that the diaphragm plate 6 can be inside the main body 1. When replacement is needed, the retaining ring 3 can be removed from the main body 1. The diaphragm plate 6 on the inner wall of the retaining ring 3 is removed by a fixing ring 7, which is fixed by a fastener 4. The diaphragm plate 6 is installed inside the snap-fit ​​groove 10 by a buckle 9 on its outer side, which facilitates replacement.

[0021] The slot 10 has a slot 8 inside, and the position of the slot 8 corresponds to the position of the buckle 9. The buckle 9 is set inside the slot 8, and one side of the fixing ring 7 is in full contact with one side of the buckle 9.

[0022] The slot 8 is used to prevent the buckle 9 from being locked. The buckle 9 drives the diaphragm plate 6 through the slot 8 and installs it inside the buckle ring 3. The fixing ring 7 is set on one side of the buckle 9 and is used to limit the position of the buckle 9 to maintain its stability.

[0023] The fastener 4 is installed on the outside of the retaining ring 3 and is located at both ends of the retaining ring 3. The inner wall of the fastener 4 is in full contact with the outer side of the fixing ring 7, and the fastener 4 is provided with a fixing plate 14 inside, which is located on one side of the fixing ring 7.

[0024] The main function of the fastener 4 is to limit the position of the fixing ring 7, so that the two fasteners 4 are set together and respectively set at the upper and lower ends of the retaining ring 3. The fastener 4 is fixed and clamped to both sides of the retaining ring 3 through the fixing plate 14 inside it. One side of the fixing plate 14 contacts the outer side of the fixing ring 7, so that the fixing ring 7 can be fixed inside the retaining ring 3.

[0025] The fixing member 4 has an inner groove 12 inside, and the inner groove 12 is located on one side of the fixing ring 7. The fixing plate 14 is installed on the inner wall of the inner groove 12, and the outer side of the fixing plate 14 is slidably connected to the inner wall of the inner groove 12. The inner groove 12 is provided with a fixing spring 13, and the two ends of the fixing spring 13 are fixedly connected to the inner wall of the inner groove 12 and one side of the fixing plate 14, respectively.

[0026] The fixing plate 14 is disposed on the inner wall of the inner groove 12 and is slidably connected to the inner wall of the inner groove 12. The two ends of the fixing spring 13 are fixedly connected to the fixing plate 14 and the inner wall of the inner groove 12 respectively. When the fixing plate 14 is in full contact with one side of the fixing ring 7, the fixing spring 13 will generate elastic force through elastic deformation and stably clamp the fixing ring 7.

[0027] The fastener 4 has an installation groove 11 inside, and the installation groove 11 has a disassembly part 5 inside. The two ends of the disassembly part 5 are respectively fixedly installed with inclined partitions 15, and the inclined partitions 15 are located on the upper side of the fastener 14.

At this time, the force generated by the fixing spring 13 will be completely isolated by the inclined partition 15, making it easier to remove the fixing part 4 and take out the diaphragm plate 6 for replacement.

[0029] Working principle: The slot 2 inside the main body 1 is used to insert the retaining ring 3. The inner wall of the retaining ring 3 is fitted with a diaphragm plate 6. The retaining ring 3 is inserted into the slot 2 from the top of the main body 1, so that the diaphragm plate 6 is inside the main body 1. When replacement is needed, simply remove the retaining ring 3 from the main body 1. The diaphragm plate 6 on the inner wall of the retaining ring 3 is removed by a fixing ring 7. The fixing ring 7 is fixed by a fixing member 4. The fixing member 4 is fixed and clamped to both sides of the retaining ring 3 by a fixing plate 14 inside it. One side of the fixing plate 14 is connected to the fixing ring 7. The outer contact allows the retaining ring 7 to be fixed inside the retaining ring 3. The retaining spring 13 will generate elastic force through elastic deformation and stably clamp the retaining ring 7. When the retaining part 4 is removed, the disassembly part 5 is moved vertically, causing it to move the inclined spacer 15 vertically. This allows the inclined spacer 15 to move the retaining plate 14, separating the retaining plate 14 from one side of the retaining ring 7. At this time, the force generated by the retaining spring 13 will be completely isolated by the inclined spacer 15, making it easier to remove the retaining part 4 and take out the diaphragm plate 6 for replacement.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
