The gripping and pulling means of the shoe repair

by the vertically reciprocal pulling member 40 and the
tong-like gripping member 41. Pulling member 40 is
selectively vertically reciprocally mounted in a usual
frame 42, which frame may be mounted on the upper
surface of the holding member 23 rearward of heel open~

Pulling member 40 is mounted vertically overlying and
