The specific embodiment

Below in conjunction with accompanying drawing the present invention and advantage thereof are described further.

Fig. 1, Fig. 2 are the structure charts of present embodiment, and the triangle 3 that resets is the T font, and support 1 is approximate inverted T-shape, and the triangle 3 that resets places the top of support 1, and both middle parts are superimposed and connected by screw 7.The two ends, the left and right sides of support 1 respectively with first, second parallel four-bar linkage 17,18 in the lower end of two forks 2,5 hinged, the upper end of fork 2,5 respectively with translation bar 4 on two ends hinged, rise cam 9 is installed in a side of translation bar 5 by screw 7, withdrawal of needle inclined-plane 10 on it, vertical plane 24 are connected by horizontal upper end face 11, and the spigot surface of control sinker needle central portion 15 swings is formed on withdrawal of needle inclined-plane 10, the inclined-plane 12 that resets.The downside of rise cam 9 has a rectangular indentation, is used to rabbet magnetic block.Magnetic block 20 adopts permanent magnets and tightly puts a magnetic inductive block 21 in both sides respectively in the present embodiment, to reduce the loss of the magnetic line of force in conduction, increase magnetic force, around the magnetic conductor that permanent magnet 20 and magnetic inductive block 21 are formed, is connected and makes it to become one and the rectangular block of above-mentioned rectangular indentation correspondence and rabbeting wherein every magnetic resin abaculus 22.The middle part of the fork 5 in hinged first, second parallel four-bar linkage of two ends difference of connecting rod 6, in fact this formed a parallel four-bar linkage again by connecting rod 6, two forks 5 and support 1---the 3rd parallel four-bar linkage 19.The distance of two pin joints is decided by the distance of two forks, the 5 lower end pin joints in the first and second row parallel four-bar linkages on the connecting rod 6, guarantee like this to form another parallel four-bar linkage 19 after connecting rod 6 connects two parallel four-bar linkages, make that the pendulum angle of both sides parallel four-bar linkage 17,18 is identical, but the present position dissmilarity sees also Fig. 3.When fork in first parallel four-bar linkage 17 5 and horizontal direction acute angle angle are this swing extreme position of α, the rise cam 9 that connects on the translation bar 4 is positioned at lower position-arresting and puts, this moment the fork 2 in second parallel four-bar linkage 18 to be in the acute angle angle of horizontal direction be another swing extreme position of β, the rise cam 9 that connects on the translation bar 4 is positioned at upper position-arresting and puts.

Apparatus of the present invention are installed on the head 14 by screw 7 by the installing hole 8 at support 1 downside two ends, 15 ones on pin clock on the sinker 25 interts in by rise cam 9 and the neutral between the triangle 3 of resetting, referring to Fig. 3, head motion is to a certain position, clock pin portion 15 on the 12 pairs of sinkers 25 in inclined-plane that reset on the withdrawal of needle inclined-plane 10 on the rise cam 9 or the triangle 3 that resets pushes effect, sinker 25 is rotated relative to steel wire turning cylinder 27, thereby the pressure of 28 pairs of fabrics of control sinker 25 line ball portions is dark

Referring to Fig. 4, during work, apparatus of the present invention are with head 14 reciprocating motion on needle-bar 16, when head 14 moves to end positions A and A ', need to change the direction of motion, the spigot surface of sinker needle central portion also will change, head 14 is at the endpoint location of needle-bar 16 at this moment, sinker is not set on this position, the row's example that does not promptly have needle central portion, how to make the variation of spigot surface, rather than realize that with relevant complicated transmission mechanism this is the remarkable substantive distinguishing features that the present invention is compared with prior art had with individual motor.The spigot surface that the inclined-plane 12 that resets on the inclined-plane 10 on the rise cam 9 and the triangle 3 that resets is formed sinker needle central portion 15, when head is advanced from right to left, the rise cam 9 of first parallel four-bar linkage 17 on the left of contrast Fig. 4 is arranged in is in upper position-arresting and puts, rise cam 9 in second parallel four-bar linkage 18 on right side is in lower position-arresting and puts, sinker needle central portion 15 is pushed upwards the upper end 11 until rise cam 9 under the guiding on the inclined-plane on the rise cam 9 10, advance with respect to this end face, because sinker needle central portion 15 is upwards pushed, sinker is rotated around steel wire rotating shaft 27, its line ball section can compress the lopping that fell guarantees knitting needle, head 14 inclined-plane 12 that resets, right side on the triangle 3 that resets that continues to advance is run into sinker needle central portion 15 and is pushed to being issued to and reset.When head 14 runs to left position, head 14 left parts exceed needle-bar 16 left parts, first parallel four-bar linkage 17 of left end of the present invention also exceeds needle-bar 16 left parts, 18 of second parallel four-bar linkages of right part are in needle-bar 16, rise cam 9 on it is tightly inhaled on needle-bar, when head 14 returns when moving from left to right, head 14 drives connected support 1 and the triangle that resets moves right together, second parallel four-bar linkage then can not movement therewith because of the suction of 20 pairs of needle-bars 14 of magnetic block in the rise cam on it, just in time make a counter-clockwise swing with respect to head 14, and drive first parallel four-bar linkage 17 by connecting rod 6 and do in the same way simultaneously, swing with amplitude, rise cam 9 in second parallel four-bar linkage is along with the rotation of two forks is displaced to upper position-arresting by lower position-arresting, 9 of rise cams in first parallel four-bar linkage are displaced to lower position-arresting by upper position-arresting, the left side 29 of connected translation bar 4 was subjected to the spacing of support middle part right flank 30 when the rise cam 9 in second parallel four-bar linkage ran to upper position-arresting, the second parallel four connecting rod machines are stopped swinging, then first parallel four-bar linkage also stops swinging, and first at random move right to right end position, and vice versa.

When head 14 does not change the direction of motion in the two-end-point position, be that head 14 is when also being in the position of the arrangement that sinker 25 is arranged on the needle-bar 16, reciprocal athletic meeting makes the vertical plane 24 on 15 pairs of rise cams 9 of needle central portion of sinker push effect, and make wherein under the magnetic force acting in conjunction that produces with permanent magnets 20 that a parallel four-bar linkage rotates, the drive by connecting rod 6 make another parallel four-bar linkage do simultaneously in the same way, with the swing of amplitude.
