The dog laminating diaphragm district can block red phosphorus, and can not take place the accident of card pipe, and the bracing piece can prevent to warp the card pipe because of the dog that the red phosphorus overweight leads to.

Further, the middle part cover of bracing piece is equipped with the material passageway, fixedly connected with connecting rod between material passageway and the bracing piece, and the connecting rod plays the supporting role to the material passageway.

Furthermore, the diameter of one end of the material channel is smaller than the diameter of the middle thin neck of the quartz ampoule bottle, the diameter of the other end of the material channel is larger than the maximum diameter of the quartz ampoule bottle, and in the charging process, red phosphorus directly enters the red phosphorus area through the material channel, so that red phosphorus is prevented from being adhered to the middle thin neck wall of the quartz ampoule bottle.

Furthermore, the one end fixedly connected with handle that the dog was kept away from to the bracing piece, the person of facilitating the use takes appurtenance.

Further, the connecting rod has threely and is cylindrically, and three connecting rod makes the support and the fixed effect to material passageway better, and the columniform sets up for when feeding, red phosphorus can follow the roll-off on the cylindrical connecting rod, avoids red phosphorus deposit on the connecting rod.

Furthermore, the handle is provided with anti-skid lines; when the handle is held by hands, the anti-skid function can be achieved.

Furthermore, the support rod between the material channel and the stop block is provided with scale marks, and the amount of added red phosphorus can be determined by observing the scale marks in the red phosphorus charging process.

The utility model has the advantages that:

(1) the utility model discloses a dog that minor diameter portion and major diameter portion are constituteed can the isolated diaphragm district, prevents that the diaphragm from gluing red phosphorus and leading to the diaphragm pressure measurement inaccurate, and split pipe or fried pipe.

(2) The utility model discloses a setting of bracing piece can prevent to lead to the dog to warp the card pipe because of red phosphorus is overweight.

(3) The utility model discloses a material passageway's setting is at the in-process of feeding, prevents that the thin neck wall in middle part of quartz ampoule from gluing red phosphorus, influences subsequent process.

(4) The utility model discloses the setting up of well scale mark makes the volume of adding red phosphorus more accurate.
