Afterwards, the puncture path 3 of a needle tubing 2 is formed in batching pig, path 3 is punctured and runs through whole batching pig 1, path 3 is punctured and is coated on pin
The periphery of pipe 2 and tube wall to needle tubing 2 has press force, especially, puncturing between path 3 and the tube wall of needle tubing 2 has gap
4, which is used to reduce the contact area between the tube wall for puncturing path and needle tubing, thus reduce needle tubing with puncture path it
Between frictional force.
Specifically, batching pig 1 extends to the inside of batching pig 1 or through batching pig with least one from 1 outer wall of batching pig
Passage 5, when to extend to the passage 5 inside batching pig from batching pig outer wall, passage 5 has positioned at 1 outer wall of batching pig
Opening 51, and its axis intersects with puncturing the axis of path 3, as long as meeting that passage axis intersects i.e. with puncturing the axis of path
Can, the concrete form of unlimited routing, can be it is linear also can be arc line type；The blind end 52 of passage 5 is located at batching pig 1
Inside, and blind end 52 and opening 51 be respectively positioned at the both sides for puncturing path 3, passage 5 and puncture path 3 crossover sites be between
Gap 4, blind end are to extend in batching pig or are that batching pig punctures the channel wall of path in itself；When for through the logical of batching pig 1
During road, passage 5 has two openings positioned at 5 outer wall of batching pig, and its axis intersects with puncturing the axis of path 3；Two are opened
Mouth is respectively gap 4 with the crossover sites for puncturing path 3 positioned at the both sides for puncturing path 3, passage 5.Certain passage does not limit to
In this, its also can integrated injection molding inside batching pig, it is only necessary to meet passage with puncture path there are crossover sites,
Crossover sites are gap.For the passage of refinement description this programme, description is refined to the form of passage, passage includes cylinder
Shape passage, tapered channel, cuboid passage, ellipsoid passage and obform body passage.Preferably cylindrical shape and cuboid passage.It is logical
Road axis has angle of intersection with puncturing path, and angle of intersection is 0 ~ 180 °, and angle of intersection is preferably 15 ~ 165 °.With 45 °, 90 °
