And lightening can be achieved. Here, when the spell sheet T is thick,
Stay that penetrates the spell sheet T
Since the length of the tip Sc (see FIG. 59) of the pull S1 is short,
The clinchers 401 and 402 use the axes 404 and 405 as fulcrums.
Thus, the amount of rotation of the rotation becomes small. That is,
Using the shaft 117 of the launcher operating members 410 and 411 as a fulcrum.
Of the clincher link 420
The amount is also smaller. As a result, the clincher cam 514 is
