The top of the vent hole 26 is tightly fitted with the bottom of the connecting hole 311. The fitting is sealed to prevent the extinguishing agent from leaking. The diameter of the connecting hole 311 is the same as the diameter of the vent hole 26, which can ensure smooth flow of the extinguishing agent and reduce resistance.

[0015] Working principle: When the fire extinguisher needs to be used, the bottom of the lock head 31 is connected to the top of the locking block 21. The two ends of the reciprocating groove 314 inside the lock head 31 are connected to the button 36. The slider 38 at the bottom of the connecting plate 37 inside the button 36 slides into the groove 22 of the locking block 21 and finally locks into the slot 23. The spring 39 inside the connecting plate 37 is connected to the stop block 313. The top of the lock head 31 is equipped with a trigger 33 and the rear is equipped with a handle 32. The right side is connected to the nozzle 35 via the fixing block 34. First, pull the pull plate 25 to drive the locking plate 24 out of the locking block 21 to release the blockage of the air outlet 26. Then press the button 31. The buttons 36 on both sides, the connecting plate 37, the compression spring 39, and the slider 38 slide along the movable groove 312 and the sliding groove 22 to ensure a stable connection. Pressing the trigger 33 allows the extinguishing agent in the fire extinguisher to enter the air outlet 26 of the locking block 21 through the main body 1, and then spray out through the connecting hole 311 and the air spray groove 310 of the lock head 31, and out through the nozzle 35 in the fixed block 34. Releasing the trigger 33 stops the air spray, and pushing the pull plate 25 causes the locking plate 24 to slide back into the locking block 21, blocking the air outlet 26. Releasing the button 36 causes the spring 39 to reset and drive the slider 38 to lock back into the slot 23, completing the locking.
