[0035] With reference to Figure 1 and Figure 2 , the disassembly assembly includes a bent hook 1, the bottom of which is fixedly connected with a six-angled column 7, the outer side of the six-angled column 7 is inserted into the six-angled hole 9, the bent hook 1 is used for hooking and disassembling the sealing element, and is particularly suitable for operation in a narrow space or a complex environment, the curved design can accurately embed the edge of the sealing element, the force is conveniently applied for disassembly, and damage is reduced, the six-angled column 7 is used for connecting the bent hook 1, then the six-angled column 7 is inserted into the six-angled hole 9, and the six-angled column 7 is tightly attracted under the action of a magnet 8, different degrees of the bent hook 1 are conveniently replaced, and the six-angled structure can provide stable installation and anti-twist capability, preventing the disassembly assembly from rotating or shifting during operation.

[0036] With reference to Figure 1 , FIG Figure 2 and Figure 5 , the compression assembly includes a compression block 5, the inside of which is fixedly connected with a convex ring 11, the outside of the circular column 2 is inserted into the inside of the compression block 5, and the bottom of the circular column 2 is provided with a recess 12 outside, the compression block 5 is used for compacting the newly installed sealing element, so that the sealing element is evenly clamped in the corresponding position, the convex ring 11 is used for clamping in the recess 12, so as to realize the fixation between the compression block 5 and the circular column 2.

[0038] Working principle: when replacing the ring-shaped sealing element, the operator selects the appropriate hook 1 according to the need and inserts the hexagonal prism 7 at the bottom of the hook 1 into the hexagonal hole 9. The multi-rib design of the hexagonal prism 7 and the hexagonal hole 9 provides stable anti-torsion capability, and the magnetic attraction generated by the magnet 8 at the bottom of the hexagonal hole 9 makes the hexagonal prism 7 firmly connected and cannot fall off or slide during operation. The hook 1 hooks the edge of the sealing element, and the arc design of the hook 1 gradually pulls the sealing element out of its nesting position. This operation is particularly suitable for narrow spaces or complex environments, can accurately disassemble the sealing element, and reduces damage to the sealing groove or other components. When the plunger-shaped sealing gasket needs to be replaced, first press the pressing block 3, and the sharp column 10 slides into the sliding groove 6. Then, insert the bottom of the circular column 2 into the plunger sealing gasket to be replaced, and release the pressing block 3. Under the action of the spring 14, the sharp column 10 returns to its original position and pierces into the plunger sealing gasket, thereby firmly fixing it. Then, lift the tool upwards, and the plunger sealing gasket can be pulled out, avoiding accidental falling of the sealing gasket during replacement, greatly improving the efficiency of the replacement operation. After the replacement is completed, insert the compaction block 5 into the bottom of the circular column 2 until the protruding ring 11 is clamped into the recess 12 to form a stable connection, and use the compaction block 5 to uniformly compact the installed sealing gasket, ensuring that the sealing gasket is more closely attached to the sealing groove, improving the sealing performance and equipment stability.
