The bobbin case of bottom line, due to by the spring driven jacking block top pressure of spanner, spanner pressing plate can with connecting shaft it is in 90 °~180 ° of folder
Stopped in angular region, when spanner pressing plate and connecting shaft are into 180 °, bobbin case can be set on spanner spring base by spanner pressing plate, so
Spanner pressing plate plate is just pressed in bobbin case axial limiting on bobbin case port into 90 ° of connecting shaft, spanner pressing plate afterwards, prevents shuttle
Core, which is significantly beated, causes wire jumper failure.
Preferably, described outlet stage clip is arranged on the inside of moon circle by outlet stage clip trip bolt.Outlet stage clip is tight
Gu screw is used to fasten outlet stage clip.
Preferably, the surface of described moon circle is provided with moon circle screw.The moon, circle screw was for fixing moon circle.
Preferably, the surface of described shield needle plate is provided with shield needle plate screw.Protect needle plate screw and be used for fixed shield needle plate.
Preferably, upper edge of the described shield needle plate screw less than shield needle plate.
Preferably, described oil seal cover is circular ring.
In summary, the utility model compared with prior art, has advantageous effect in that：The utility model optimizes
Structure, make structure compacter, it is fixed reliable, the generation of wire jumper is effectively prevent, working stability, improves product quality, is extended
Service life, it can be achieved to produce application in enormous quantities.
