Further, described hook portion is formed in one the hook of structure.
Further, described hook portion is that case hardening steel is made.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) in the present invention, one end of hook portion is provided with hook, the other end is provided with rotatable parts, load portion is provided with spherical hollow space and straight hole, rotatable parts are rotatably installed in cavity, the diameter of described cavity is more than the diameter of described straight hole, after using said structure to install rotatable parts, hook portion can not come off from load portion owing to rotatable parts are blocked by cavity wall, thus ensure that the safety of the present invention；
(2) the load portion of the present invention is combined by positive stop and backstop, coordinates fastening by screw and nut, so that remove and install conveniently；
(3) present invention offers through hole in load portion, hoist cable passes through hole, load portion is suspended on hoist cable, use said structure, hoist cable can be made to be applied to the counteracting force in load portion active area in load portion bigger, and then load portion will not be pulled off because of the counteracting force of hoist cable applying, thus strengthen the safety of the present invention；
(4) present invention uses case hardening steel integrated formed structure, case hardening steel is due to case-carbonizing, surface is made to have the highest hardness, can ensure that portion of the present invention deforms, additionally case hardening steel internal toughness is strong, the part impact that the absorbable present invention accepts, and then ensure that the present invention is pulled off in the middle part of practical process, thus strengthen the safety of the present invention.
(5) in the present invention, rotating part, cavity are set to spherical so that present invention frictional force in rotation process reduces, thus strengthens the motility of the present invention.
