ABSTRACT:
A spring operated pinching device, which includes a housing defining therein a plurality of scoop channels for receiving an adjusting knob, an actuating member, a guide board member and a tool holder member, with a compression spring set between the adjusting knob and the actuating member, with a guide rod member and an eccentric spring set between the guide board member and the tool holder member, and with a board tool member fastened in the tool holder member. The downward pressing force of the housing against the board tool member forces the tool holder member to squeeze the eccentric spring permitting the guide rod member to insert through the guide board member into the actuating member so that the instantaneous expansion force from the compression spring forces the actuating member to drive the board tool member to connect a telephone wire to a wiring board by means of squeeezing process.
