And a sixth step: and then the winding roller 44 can be indirectly driven to wind the connecting waste a1 again through the rotation of the output shaft of the rotating motor 45, then the third step to the fifth step are repeated, the connecting end a2 of the terminal a can be pressed again, and the cutting knife 73 can cut the pressed terminal a from the connecting waste a1 in the process of moving downwards along with the T-shaped top plate 72.

Cut out the back when terminal a is followed connection waste material a1 by blank sword 73, will drop to transmission band 62 upper end downwards, then transmission motor 63 output shaft is rotatory can drive driving roller 61 and rotate, can drive transmission band 62 when driving roller 61 rotates and transmit the terminal a after accomplishing the pressfitting.

The seventh step: after the pressing of all the terminals a on the terminal frame b is completed, the semiannular block II is turned rightwards, so that the upper end of the winding roller 44 is not limited any more, then the winding roller 44 is taken out upwards, the connecting waste material a1 on the outer side surface of the winding roller 44 slides out from one end of the winding roller 44, and the connecting waste material a1 in a winding state can be separated from the winding roller 44.

Then the winding roller 44 is placed between the rotating round blocks 43, the rectangular protrusions on the opposite sides of the rotating round blocks 43 can be clamped with the grooves of the winding roller 44, and finally the second half-ring block 41 is turned leftwards to reset, so that the second half-ring block 41 can limit the upper end of the winding roller 44 again.

Eighth step: and when the coiled terminal a to be pressed needs to be pressed again, repeating the first step to the seventh step.
