Abstract

A pair of wire coiling tongs comprises a left tong body and a right tong body which are pivoted and staggered from each other. A rotation driving mechanism is provided at a tong handle part of one tong body. The rotation driving mechanism is provided with a driving rod which movably penetrates a seat pipe. The driving rod is provided with a forward-direction helical groove and a reverse-direction helical groove which are staggered. Two shaft sleeves are sleeved on the driving rod. Furthermore the inner walls are respectively provided with a projected rib which is matched with the forward-direction helical groove and the reverse-direction helical groove. Each shaft sleeve is additionally provided with at least one channel section. Two pressure plates are respectively provided with a projected end which extends into the channel section of a corresponding shaft sleeve. The two pressure plates are controlled by a switching member, and therefore one pressure plate raises and a projected end of the pressure plate is disengaged from the channel section of the corresponding shaft sleeve. The projected end of the other pressure plate is maintained in the channel section of the corresponding shaft sleeve. Thereby, a metal wire which is clamped by a tong jaw part of the tong body can be controlled for being wound in the forward direction or being unwound in the reverse direction.
