Further, turn over pin triangle overhead height and turn over pin slide block height and match.
The present invention is in when work, and the pin bell is at first up along turning over the oblique track of pin triangle, and when moving to when turning over pin triangle top, the pin bell is conflicted and turned over the pin slide block, and promotes to turn over the translation in the groove of cam base plate of pin slide block, thereby pin bell itself also carries out translational motion; When turn over the pin slide block move to the contact other end turn over the pin triangle time, the pin bell descends along the outline line that the other end turns over the pin triangle, thereby accomplishes whole track.And when the heading reverse motions, when promptly the pin bell was with respect to the cam base plate opposite-oriented movement, its movement locus also was symmetrical fully.
Visible from above description, technical scheme of the present invention only need design one and hold the track that moves level with both hands, promptly can on the both direction of pin bell motion, all use this section track, has therefore saved the space of cam base plate greatly; Translational motion is to lean on the pin bell to promote to turn over the pin slide block to carry out, and is simple in structure, and fault rate is low, can finish the work reliably.
