[0028] Anti-falling components are provided on both the front and rear sides of the interior of the mounting seat 6, and the anti-falling components include a square groove 12, a second spring 13, a clamping plate 14 and a third spring 15. The square groove 12 is opened inside the mounting seat 6. When the clamping block 9 contacts the square groove 12, the spring 11 is no longer compressed. When the sealing ring 8 enters the interior of the placement groove 7, the clamping block 9 will enter the interior of the square groove 12, and then the clamping block 9 will squeeze the spring three 15. One end of the second spring 13 is fixedly connected to the bottom of the square groove 12, and the outside of the clamping plate 14 is slidably connected to the inner wall of the square groove 12. The outside of the clamping block 9 is slidably connected to the inner wall of the square groove 12, and the outside of the clamping block 9 is clamped with the outside of the clamping plate 14.

[0029] One end of spring three 15 is fixedly connected to the bottom of the card plate 14. At this time, spring three 15 is pushed inward to squeeze the card plate 14. The other end of spring three 15 is fixedly connected to the outside of the card plate 14. At the same time, spring two 13 and spring three 15 are squeezed by force, and the block 9 slides over the outside of spring three 15. Spring two 13 and spring three 15 are no longer compressed. The square groove 12 contacts the outside of the block 9 to prevent the block 9 from escaping from the inside of the square groove 12. Then, the cylinder 2 is started. Under the drive of the cylinder 2, the push rod 3 drives the sleeve rod 4 to enter the middle part of the mounting seat 6, and then enters the inside of the membrane shell 5 and pushes upward, which is convenient for disassembling the mounting seat 6 and the sealing ring 8, reducing damage to the outside of the sealing ring 8 and ensuring the use effect.

[0030] Reference Figure 1 and Figure 5Adjustment components are provided on the left and right sides of the top of the elastic plate 1, and the adjustment components include multiple rubber columns 16, multiple spring fours 17 and two rubber plates 18.

[0031] The other end of the spring four 17 is fixedly connected to one side of the rubber plate 18. At this time, the spring four 17 is compressed by force, and due to its own elastic characteristics, it absorbs external force during compression and generates a reaction force on the rubber plate 18. The adjacent sides of the two rubber plates 18 are in contact with the outside of the membrane housing 5, so that the rubber plate 18 is in closer contact with the outside of the membrane housing 5. Due to its elasticity, it can adapt to membrane housings 5 ​​of different sizes, so that membrane housings 5 ​​of different sizes can be fixed to ensure the effect when pushing out.

[0032] Working principle: first, place the membrane shell 5 in the middle of the elastic plate 1, then pull the elastic plate 1 to both sides to make the membrane shell 5 enter the middle of the elastic plate 1, at this time, the membrane shell 5 will squeeze the rubber plate 18, and the rubber plate 18 will squeeze the rubber column 16 and the spring four 17 to both sides. At this time, the spring four 17 is compressed, and due to its own elastic properties, it absorbs external force during compression, and generates a reaction force on the rubber plate 18, so that the rubber plate 18 is in closer contact with the outside of the membrane shell 5, and can adapt to membrane shells 5 of different sizes due to its elasticity. Then, put the sealing ring 8 into the placement groove 7 inside the mounting seat 6, and the sealing ring 8 is stuck in the block 9 when entering the inside of the placement groove 7. It will enter the interior of the square groove 12, and then the block 9 will squeeze the spring three 15. At this time, the spring one 11 is compressed inside the cavity 10. At this time, the spring three 15 is pushed inward to squeeze the card plate 14, and at the same time, the spring two 13 and the spring three 15 are squeezed. When the block 9 contacts the square groove 12, the spring one 11 is no longer compressed, and the block 9 slides over the outside of the spring three 15. The spring two 13 and the spring three 15 are no longer compressed. The square groove 12 contacts the outside of the block 9 to prevent the block 9 from escaping from the inside of the square groove 12. Then the cylinder 2 is started, and under the drive of the cylinder 2, the push rod 3 drives the sleeve rod 4 to enter the middle of the mounting seat 6, and then enters the interior of the membrane shell 5 and pushes upward.
