Claim 6:
7. An anti-torque safety hook, comprising:
a main body, having a hook opening passing through the front and back sides thereof, a passage communicating to said hook opening, a female buckle arranged above said passage, a connection unit arranged below said hook opening, and an energy absorption area arranged on a left side of said hook opening, wherein said female buckle and said passage are located on a right side of said energy absorption area;
a gate member, having a first end mounted on said main body and a second end comprising a male buckle, adapted for detachably coupled with said female buckle, so as to allow said gate member to open and close said passage: and
a detent member, coupled on said main body and maintained at a first position, so as for ensuring that said gate member closes said passage,
wherein when said detent member is operated and switched to a second position, a safety is disarmed, so that said gate member is operable for opening said passage, wherein when said detent member is armed when said gate member closes said passage, when said main body bears a designated torque, said energy absorption area allows said main body to distort in response, so as to ensure that said gate member still closes said passage, wherein said main body has a main arm, a hook arm, and the hook opening is defined by connecting said hook arm with a top end of said main arm, wherein the passage is provided and maintained between a free end of said hook arm and a right side of said main arm, wherein said hook arm has the female buckle arranged on the free end thereof, wherein said main arm has the connection unit arranged below said hook opening and the energy absorption area is arranged between said connection unit and said hook arm, and is a channel laterally passing through a left and right side of said main arm, wherein said main arm has a symmetrically shaped front board and back board, wherein an end of said hook arm is affixed between atop end of said front board and a top end of said back board in a clamping manner, wherein said connection unit has an intermediate block affixed between a bottom end of said front board and a bottom end of said back board in a clamping manner, wherein said hook arm and said intermediate block control and keep said energy absorption area between a back side of said front board and a front side of said back board, wherein said connection unit is formed by said intermediate block, a main bolt, and a breaking bolt, wherein said intermediate block has a covered portion and a bare portion, wherein said covered portion is clamped between the bottom end of said front board and the bottom end of said back board and affixed through a pinning of said main bolt and said breaking bolt, wherein the strength of said breaking bolt is lower than the strength of said main bolt, wherein said bare portion has a hanging hole penetrated thereon, wherein said anti-torque safety hook further comprising a spring mounted between said detent member and said intermediate block, so that said spring provides a predetermined force onto said detent member to grant said detent member a potential to stay at the first position.
