Needle sewing switching, when can also realize crosspointer work, there are spare syringe needles, even if a damage, converts needle head structure, you can after
Continuous work, practical function are notable.
The technology solution of the utility model is as follows：
A kind of adjustable double needle machine needle head structure, includes triangular mounting plate, and the center of the triangular mounting plate is hung down
Straight to be fixed with the bar that is screwed, the triangular mounting plate opens that there are three straight slot, institutes with the axle center annular array for the bar that is screwed
Straight slot one end is stated towards the bar that is screwed, the straight slot other end is respectively facing three angles end of triangular mounting plate, described logical
Two madial wall of slot forms strip sliding rail, and adjustable needle head structure, the straight slot are slidably connected in the strip sliding rail
It is fixed with compressed spring on the inner wall of bar side that is screwed, the straight slot other end is equipped with positioning bolt.
Preferably, the adjustable needle head structure includes the sliding shoe being slidably matched with strip sliding rail, the cunning
Helical axis is fixed with below motion block, the helical axis cooperation is equipped with syringe needle mounting bracket, needle is equipped in the syringe needle mounting bracket
Head.
Preferably, the compressed spring other side is fixedly linked with needle head structure.
Preferably, the positioning bolt is mounted at three acute angles of triangular mounting plate.
Preferably, the sliding shoe two sides form the tenon coordinated with strip sliding rail.
Preferably, being fixed with extension spring below the helical axis.
Preferably, inside forms the screw thread coordinated with helical axis above the syringe needle mounting bracket.
The beneficial effects of the utility model are：
A syringe needle job may be selected when work for the design of three syringe needles, can also select two syringe needles work, facilitate reality
The switching of existing single needle and crosspointer work uses, and when one syringe needle work of selection, can rotate up syringe needle mounting bracket, will be on syringe needle
It moves, the distance for regulating syringe needle to sewing machine table can adjust the spacing of two syringe needles when two syringe needle work of selection, if
Different positions is set, and the front and back position of two syringe needles is adjusted, facilitates the work in corner place, while when two syringe needle works
When making, remaining syringe needle can be as spare, and using effect is good.

Specific implementation mode：
As shown in Figs 1-4, a kind of adjustable double needle machine needle head structure, includes triangular mounting plate 1, the triangle peace
The center of loading board 1 is vertically and fixedly provided with the bar 2 that is screwed, and the triangular mounting plate 1 is with the axle center annular array for the bar 2 that is screwed
It opens there are three straight slot 3, for 3 one end of the straight slot towards the bar 2 that is screwed, 3 other end of the straight slot is respectively facing triangle installation
Three angles end of plate 1,3 liang of madial walls of the straight slot form strip sliding rail, and being slidably connected in the strip sliding rail can
Needle head structure 4 is adjusted, the straight slot 3 is fixed with compressed spring 5 on the inner wall of 2 side of bar that is screwed, and the straight slot 3 is another
One end is equipped with positioning bolt 6.
Specifically, the adjustable needle head structure 4 includes the sliding shoe 7 being slidably matched with strip sliding rail, the cunning
7 lower section of motion block is fixed with helical axis 8, and the cooperation of the helical axis 8 is equipped with syringe needle mounting bracket 9, is installed in the syringe needle mounting bracket 9
There is syringe needle 10, it is ensured that needle head structure can be moved effectively in strip sliding rail.
Specifically, 5 other side of the compressed spring is fixedly linked with needle head structure 4, it is ensured that needle head structure 4 has stress.
Specifically, the positioning bolt 6 is mounted at three acute angles of triangular mounting plate 1, ensures that positioning bolt 6 can fill
Divide and provides thrust to needle head structure 4.
Specifically, 7 two sides of the sliding shoe form the tenon 71 coordinated with strip sliding rail, ensure adjustable syringe needle
