Abstract

The disclosure relates to a hand operated shearing tool, comprising a first unit (1) comprising a first blade (11) and a first handle (12) fixed to the first blade (11) at a proximal end (111) of the first blade (11), the first blade (11) comprising a first cutting edge (112); and a second unit (2) comprising a second blade (21) and a second handle (22) connected to the second blade (21) at a proximal end (211) of the second blade (21), the second blade (21) comprising a second cutting edge (212), wherein the second unit (2) is connected rotatably to the first unit (1) by a pivot (3); the second handle (22) is connected to the second blade (21) by the pivot (3) so that rotational movement of the second handle (22) in relation to the second blade (21) is allowed; the second blade (21) comprises a first hole (213) arranged at the proximal end (211) of the second blade (21); the second handle (22) comprises a second hole (221); the second unit (2) comprises a pin (23) comprising a body (231) and a head (232) attached to an end of the body (231); the pin (23) is arranged in the first hole (213) and the second hole (221) so that the body (231) penetrates the first hole (213), a part of the body (231) is in the second hole (221) and the head (232) is between the first blade (11) and the second blade (21); the first hole (213) is arranged to allow tilting of the pin (23) in relation to the second blade (21); the second hole (221) is arranged to allow tilting of the pin (23) in relation to the second handle (22); the second handle (22) and the second blade (21) are arranged to exert a tilting force to the pin (23) due to a shearing force (F1) between the second handle (22) and the second blade (21); as a result of the tilting force, the head (232) is arranged to exert a separating force (F2) to the proximal end (111) of the first blade (11) and the proximal end (211) of the second blade (21) driving the proximal end (111) of the first blade (11) and the proximal end (211) of the second blade (21) away from each other; and as a result of the separating force (F2), the first blade (11) and the second blade (21) are arranged to exert a compressive force (F3) driving the first blade (11) and the second blade (21) towards each other at the opposite side of the pivot (3) for increasing the cutting capacity of the shearing tool.
