When the rotating shaft 1 rotates, the position change of the right side surface relative to the second roller 32 causes the right side surface of the track 11 to interfere with the second roller 32, so that the push rod 2 is pushed to move rightwards, and the limiting rod cannot rotate around the rotating shaft 1 due to the arrangement of the limiting mechanism.
The rotation of the shaft 1 is continued, and the change of the position of the left side surface relative to the first roller 31 causes the left side surface of the rail 11 to interfere with the first roller 31, so that the push rod 2 is pushed to move leftwards, and the limit rod cannot rotate around the shaft 1 due to the arrangement of the limit mechanism.
The rotating shaft 1 continuously rotates to realize the reciprocating motion of the push rod 2.
