In order to prevent the material guide pipe from being blocked at the inlet of the single-pipe material guide groove 3.2, a vibrating mechanism is further arranged on the material bin. Specifically, as shown in fig. 9-11, a vibrating pushing plate 3.9 is arranged above the pushing plate 3.3, a horizontal rotating shaft 3.10 is arranged at the bottom of the storage tank 3.1, a transmission plate 3.11 matched with the vibrating pushing plate 3.9 and a vibrating block 3.12 for disturbing a material guiding pipe are fixedly connected to the horizontal rotating shaft 3.10, and a reset spring 3.13 connected with the outer wall of the single-pipe material guiding tank 3.2 is further arranged on the vibrating block 3.12.
When the device is used, the fire extinguisher hand-press handles pre-screwed with the pressure gauges are clamped and fixed on the jig plates 1.2, so that the fire extinguisher hand-press handles are sequentially moved to the lower part of the pressure gauge screwing mechanism 2 and one side of the material guide pipe installation mechanism 3 along the annular conveying chain 1.1, and meanwhile, the pressure gauge screwing operation and the material guide pipe installation operation are respectively carried out on the fire extinguisher hand-press handles on the two jig plates 1.2.

Then, lifting plate 1.6 moves up under the effect of location cylinder 1.5, makes locating pin 1.7 insert in locating hole 1.3 to the jig location, avoids fire extinguisher hand push handle to take place the position offset in the installation.
When the pressure gauge screwing mechanism 2 is used for screwing the hand-press handle of the fire extinguisher, the clamping cylinder 2.2 acts, the push rod 2.4 is pressed down to enable the U-shaped connecting rod 2.11 to drive the push arm 2.12 to rotate, further the left and right longitudinal clamping arms 2.10 are clamped towards the middle, when the horizontal clamping plate 2.9 of the longitudinal clamping arm 2.10 firmly clamps the hexagonal connection nut of the pressure gauge, the motor 2.6 drives the rotating wheel 2.5 to rotate, and meanwhile the door-shaped frame 2.8, the longitudinal clamping arm 2.10, the push rod 2.4 and the hexagonal connection nut of the pressure gauge are driven to rotate, so that the pressure gauge is screwed on the hand-press handle of the fire extinguisher.
When the guide pipe installation mechanism 3 is used for installing the guide pipe on the fire extinguisher hand-press handle, the single guide pipe positioned at the lowest end of the single-pipe guide groove 3.2 is pushed out by the pushing plate 3.3 under the driving of the horizontal cylinder, the single-pipe guide groove reaches the screwing pipe area after passing through the single-pipe feeding baffle 3.4, then the pushing plate 3.3 and the single-pipe feeding baffle 3.4 return to the original positions, the screwing pipe motor 3.6 moves towards the screwing pipe area under the action of the pushing and pulling cylinder, the guide pipe is pushed into the installation hole of the fire extinguisher hand-press handle, the screwing pipe shaft 3.7 penetrates into the guide pipe, the limiting protrusion 3.8 is clamped at the inlet edge of the guide pipe to prevent the guide pipe from rotating, then the screwing pipe motor 3.6 works, the guide pipe is driven to rotate, and the guide pipe is screwed on the fire extinguisher hand-press handle. Finally, the lifting limiting plate 3.5 moves upwards under the action of the vertical cylinder, so that the guide pipe installed on the hand-pressure handle of the fire extinguisher moves forwards. Because the vibration pushing plate 3.9 and the pushing plate 3.3 synchronously move, when the material is pushed each time, the vibration pushing plate 3.9 pushes the transmission plate 3.11 to rotate, and the horizontal rotating shaft 3.10 connected with the vibration pushing plate can also drive the vibration block 3.12 to rotate, so that a material guiding pipe close to the inlet of the single-pipe material guiding groove 3.2 is disturbed, and the phenomenon of blockage and non-discharging is prevented.
After the tightening operation of the pressure gauge and the installation operation of the material guide pipe are completed, the lifting plate 1.6 moves downwards, the positioning of the positioning pin 1.7 on the jig plate is released, the annular conveying chain 1.1 continues to operate, and the pressure gauge and the material guide pipe are installed on the hand-press handle of the fire extinguisher on the subsequent jig plate according to the steps.
