Specific implementation mode
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
Embodiment：A kind of push-pin mechanism, including pedestal 1, bearing block 2, power spindle 3, side are equipped with pushing away for fixed crochet hook
Punch block 4, equal mirror image are distributed in the driving mechanism and guiding mechanism of 1 both sides of pedestal, and the power spindle 3 is installed by bearing block 2
Stepper motor outside on pedestal 1, connecting and driving mechanism.It is one in multiple crochet hook actual productions shown in attached drawing 1
Entire row, but in order to preferably show the structure for frame of pushing pin has drawn fragmentary several expressions at this.
The driving mechanism includes variable eccentric 5, rotary joint 6, and the variable eccentric 5, is pushed pin at rotary joint 6
Frame 4 is sequentially connected, and for providing power for frame 4 of pushing pin, the variable eccentric 5 includes bearing inner sleeve 11, bearing capping 12, axis
13, bearing outside 14, bolt are held, the bearing outside 14 is socketed bearing 13, and the bearing 13 is socketed bearing capping 12 and bearing
Inner sleeve 11；The bearing capping 12 abuts against cooperation, and the intermediate U-shaped opening being equipped with for connecting shaft, institute with the composition of bearing 13
It states U-shaped opening both sides and is equipped with elongated slot, centre bore corresponding with U-shaped opening, the center are equipped among the bearing inner sleeve 11
Hole side is equipped with threaded hole corresponding with elongated slot respectively, and the elongated slot is bolted cooperation with threaded hole.When needing to adjust
When saving eccentricity, the bolt in bearing capping 12 is unclamped, toward elongated slot length direction movement bearing capping 12 and bearing inner sleeve 11
Relative position, and then the centre-to-centre spacing in the center of circle and the 11 endoporus center of circle of bearing inner sleeve of bearing outside 14 is adjusted, to adjust eccentricity
Size.The bearing covers the round screens portion 15 that 12 lower ends are equipped with protrusion, what the circle screens portion 15 was equipped with bearing 13
