When the staff moves the slot 404, in order to avoid the slot 404 being unstable when moving up and down, and easy to be misplaced and stuck, through the setting of the slide groove 407 and the slider 408, the sliding plate 402 drives the slider 408 to move inside the slide groove 407 when moving, and the moving track of the sliding plate 402 is fixed, so that the sliding plate 402 moves stably. When the user needs to generate gas other than fuel gas during use, in order to avoid alarm In case of a false alarm of the device 3, the staff pushes the blocking plate 7 into the protective shell 5 to close the alarm device 3. The staff pulls the pressure plate 608 to drive the slide plate 606 and the telescopic rod 607, so that the slide plate 606 pushes the sliding ring 603. The sliding ring 603 squeezes the thrust spring 604 to stretch and store force. The staff releases the pressure plate 608. The thrust spring 604 quickly presses the pressure plate 608 against the blocking plate 7 to fix it under the action of the rebound force. In order to make the movement of the sliding ring 603 more stable, the sliding groove 609 and the sliding block 610 are set. When the staff moves the sliding ring 603, the sliding ring 603 drives the sliding block 610 moves inside the sliding groove 609 to fix the moving trajectory of the sliding ring 603 and avoid jamming caused by misalignment. In order to avoid jamming caused by misalignment of the blocking plate 7 when the staff pulls the blocking plate 7 to move outward, making it difficult for the blocking plate 7 to be pulled outward, through the setting of the moving groove 8 and the moving block 9, the staff pulls the blocking plate 7 to drive the moving block 9 to move inside the moving groove 8, so that the moving trajectory of the blocking plate 7 is fixed and slides steadily.
