When the material guide tube installation mechanism 3 installs the material guide tube on the hand pressure handle of the fire extinguisher, the push plate 3.3 pushes out the single material guide tube located at the bottom end of the single tube material guide groove 3.2 under the drive of the horizontal cylinder, and passes through the single tube feeding tube. After the baffle plate 3.4 reaches the tube twisting area, the pushing plate 3.3 and the single tube feeding baffle 3.4 return to their original positions, and the tube twisting motor 3.6 moves to the tube twisting area under the action of the push-pull cylinder, pushing the material guide tube into the fire extinguisher and pressing it by hand In the installation hole of the handle, and make the tube twisting shaft 3.7 penetrate into the material guide tube, make the limit protrusion 3.8 clip on the inlet edge of the material guide tube to prevent the material guide tube from rotating, then, the tube twisting motor 3.6 works, drives The material guide tube is rotated, and the material guide tube is screwed on the hand pressure handle of the fire extinguisher. At last, the lifting type limit plate 3.5 moves up under the effect of the vertical cylinder, so that the feed pipe installed on the hand pressure handle of the fire extinguisher moves forward. Because the vibrating material push plate 3.9 and the material pushing plate 3.3 move synchronously, each time the material is pushed, the vibrating material pushing plate 3.9 will push the transmission plate 3.11 to rotate, and the horizontal rotating shaft 3.10 connected to it will also drive the vibrating material block 3.12 to rotate. Rotate to disturb the feed pipe near the entrance of the single pipe feed chute 3.2 to prevent clogging and no discharge.

After the above-mentioned pressure gauge tightening operation and material guide pipe installation operation are completed, the lifting plate 1.6 moves down, the positioning pin 1.7 is released from the positioning of the opposing plate, and the endless conveyor chain 1.1 continues to run.
