ABSTRACT:
A height adjusting device for a string puller of a string pulling block of a stringing machine includes a rod member. The string pulling block is allowed to move relative to the rod member and includes the string puller and a lever disposed thereon. The string pulling block includes an upper support provided therein and having a tilted slidable mount disposed thereon. The string pulling block further includes a lower support mounted on the rod member and having a tilted coupling seat affixed thereon. The coupling seat is obliquely coupled with the lower support and involves an inclined rail arranged thereon for axially moving a sliding member therein. By attaching the coupling seat onto the sliding member, the upper support may obliquely move upward and downward along the rail, thus adjusting the height of the string puller.
