Force-multiplying pliers comprising a fixed arm (10), a moving actuating arm (14) which is hinged (16) to the fixed arm (10), and a moving support arm (18) also hinged to the fixed arm (10). Force multiplication is performed by means of a first link (28) hinged (28A) to the fixed arm (10) and of a second link (30) hinged (34A) to the support arm (18), the links being hinged together via a coupling pin (32). The pliers further comprise mechanical coupling and movement-transmitting means for mechanically coupling together and for transmitting movement between the moving actuating arm and said links, which means comprise cam means (34, 36). |
