PURPOSE: A tool having plural claws is provided to efficiently use tools by corresponding to various shapes and sizes because the number of contact points is increased and strength is uniformly added. CONSTITUTION: A tool having plural claws comprises handles(10a,10b), a main combining body(20), claws(30a,30b,30c), an elastic body(60), a shaft(50), a joining pieces(40a,40b,40c,40d), and a nut unit(70). The main combining body comprises recessed grooves(22a,22b,22c) and a projection piece(26). A plurality of the recessed grooves is formed in the upper part of the main combining body with a constant interval in a circumferential direction. The handles are joined to each through-hole(12a,12b) of the projection piece of the main combining body by a hinge. The claws are joined to the each recessed groove of the main combining body by the hinge. The elastic body applies an elastic force so that the claws are widened at a constant angle. A head(51) of the shaft is hung on each hanging sill(34a,34b,34c). One end of the joining piece is joined to the handles by the hinge and the other end of the joining piece is fixed to a connection link shaft(44). The nut unit is joined to the lower part of the shaft while the shaft penetrates the through-hole of the main combining hole and a hole(45) of the connection link shaft. |
