When the rubber sealing ring 14 is aged after long-term use and needs to be disassembled and replaced, first pull the pull plate 8 to the left, and the pull plate 8 will drive the slide plate 5 to move toward the seat through the pull rod 6, so that the spring 7 is elastically deformed under the force, so as to facilitate the next reset and fixation of the limit rod 4. The slide plate 5 will drive the limit rod 4 to move to the left, so that the limit rod 4 is separated from the limit hole 11 opened in the plug block 10, so that the limit rod 4 no longer limits and fixes the plug block 10. At this time, the panel 2 can be pulled to separate the panel 2 from the shell 1, which is convenient for replacing the rubber sealing ring 14, thereby bringing convenience to the use of the explosion-proof pulse controller.
