Claim 2:
3. 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 female buckle is formed by a slot communicated with said hook opening and a deep area connected with said slot, wherein a first groove penetrates said front board and said back board below said passage, wherein a second groove is arranged in a curvy manner with said first groove located at a center of curvature, wherein a right side of said second groove is upwardly connected with a third groove, wherein said gate member has a baffle adapted for closing said passage and two side boards that are bent to be arranged on the two sides of said baffle respectively, wherein said two side boards respectively have a first end and a second end oppositely arranged, wherein said first end covers said first groove and said third groove and bridges with a first axle that passes through said first groove and a second axle that passes through said third groove, wherein said second end of said two side boards bridges with a male buckle embedded in said deep area, so as for said gate member to close said passage, wherein when said passage is to be opened, said gate member has to be forced to shift downward, so as to drive said first axle to move to a lower portion of said first groove, said second axle to move to a lower portion of said second groove, and said male buckle to leave said deep area, rendering said gate member to swing toward said hook opening according to said first axle as the center thereof, which drives said second axle to move along said second groove and decouple said male buckle from said female buckle.
