To draw in the pipe horn mouth end inserts the push rod passageway, push up the bracing piece on the outer wall in push rod passageway exit, a rotating nut, the pull rod moves toward push rod passageway exit direction, thereby round platform column structure struts the horn mouth, the barb card is gone into in the recess, because round platform column structure cross-section maximum diameter is greater than and draws the pipe diameter, make the pull rod remove by the card owner after a section distance, a rotating nut is equivalent to the rotating and draws the pipe and the pull rod is whole behind the card owner, thereby the pull rod forms whole rotatory for No. two nuts with drawing the pipe, because No. two nuts are fixed motionless along with the backup pad bracing piece, so the pull rod with draw the pipe and screw out to push rod passageway exit for No. two nuts, thereby pull out the copper lining.
Furthermore, the drawing pipe is formed by splicing two sections. Is easy to produce.
Further, there are 4 notches and 4 barbs.
Further, the notches and barbs are equally spaced.
Furthermore, the supporting plate is provided with a threaded through hole, the supporting rod is a screw rod, and the supporting rod is screwed in the threaded through hole. The distance that the drawing tube extends into the push rod channel can be adjusted.
The utility model has the advantages that:
1. the utility model discloses in utilize the drawing pipe to pull out convenient and fast with the copper lining from the push rod passageway.
2. The utility model discloses in can also adjust wantonly and draw the pipe and get into the distance in the push rod passageway.
