Cutting or compression tool

Cutting or compression tool, comprising:

• a housing and a driving group connected to the housing and configured to move a driving piston with respect to the housing,
• a fixed jaw comprising a first connecting seat and a second connecting seat, wherein the second connecting seat is spaced from the first connecting seat and the fixed jaw is non-pivotably connected with respect to the housing through said first and second connecting seats,
• a mobile jaw identical to the fixed jaw, the mobile jaw comprising a first fulcrum seat and a second fulcrum seat, wherein the second fulcrum seat is spaced from the first fulcrum seat, and the mobile jaw is hinged to the fixed jaw through a pivotable connection between the first fulcrum seat of the mobile jaw and the second connection seat of the fixed jaw at a first fulcrum point,
• a first connecting plate having a first end hinged to the driving piston and a second end hinged to the mobile jaw through a pivotable connection at the second fulcrum seat at a second fulcrum point, so that, in response to the movement of the driving piston with respect to the housing, the mobile jaw and the fixed jaw perform a relative rotational movement about the first fulcrum point, between an open position and a closed position, in order to perform the cutting or the compression, and
• a second connecting plate having a first end connected to the housing and a second end connected to the fixed jaw through one of the first and second connecting seats, the fixed jaw being further directly connected to the housing through the other one of the first and second connecting seats, so that the housing, the second connecting plate and the fixed jaw form an articulated non-deformable triangle,
• wherein the distance between the first connecting seat and the second connecting seat of the fixed jaw is equal to the distance between the first fulcrum seat and the second fulcrum seat of the mobile jaw.
