Due to the existence of the opening groove 311 and the locking ring 32 being an elastic ring, a partial segment of the locking ring 32 protrudes out of the opening groove 311, and after the bolt locking part 31 is installed in the installation groove 211, the groove wall of the installation groove 211 presses the protruding portion, thereby compressing the opening 321.

In one embodiment, the opening slot 311 is multiple, and the multiple opening slots 311 correspond to the outer surfaces of the hexagonal cylinder respectively. The provision of the plurality of open grooves 311 increases the projection of the bolt locking portion 31, thereby increasing the elastic force provided by the locking ring 32.

In one embodiment, the receiving chamber 12 is composed of a first chamber section 121, a second chamber section 122, and a third chamber section 123, the first chamber section 121 has a maximum bore diameter to ensure that the head 21 of the screw-in bolt mounting member 20 is retained within the first chamber section 121, and the second chamber section 122 and the third chamber section 123 are penetrated by the stud portion 22 and the bolt locking portion 31, respectively. The bolt locking portion 31 has a smaller diameter than the stud portion 22 in consideration of the fact that it is only effective when the screw-in bolt attachment member 20 is installed and receives a small force.

In one embodiment, the body 10 is a hollow structure having a receiving cavity 12, and may be designed in multiple parts, and the parts are connected after the head 21 of the screw-in bolt mounting member 20 is mounted in the first cavity section 121, so that the head 21 can be securely mounted in the first cavity section 121.

In one embodiment, the length of the first cavity segment 121 is greater than the length of the head 21 such that the head 21 is movably disposed relative to the first cavity segment 121. The head 21 is made movable relative to the first chamber section 121 while ensuring its ability to rotate relative to the first chamber section 121, thereby making the positional adjustment of the two more convenient.

In one embodiment, the hoisting structure consists of a trolley, a screw-in bolt (screw-in bolt mount 20), and a bolt tacking mechanism (locking assembly 30). The lifting body is a main bearing mechanism and is provided with a circular lifting ring (lifting ring 11) and a screw-in bolt mounting cylinder (main body 10), and the screw-in bolt mounting cylinder is an internal hollow cavity. The screw-in bolt head is placed inside the installation cylinder, the screw-in bolt can move up and down in the cylinder hollow cavity along the axial direction of the bolt but can not be completely separated from the cylinder hollow cavity, and the screw-in bolt can freely rotate in the cylinder hollow cavity along the axial direction of the bolt. The head 21 of the screw-in bolt is provided with a hexagon socket counter bore (mounting groove 211), and the lower part of the stud part 22 is provided with a thread.

The handling body is connected with bolt tight nail mechanism, and bolt tight nail mechanism includes: the bolt fastening body (the bolt locking part 31 and the connecting plate 33) is an L-shaped mechanism; a locking ring 32, which is an annular device with a circular cross section and is provided with an opening 321, and the locking ring 32 is fixedly installed on the bolt fastening body by passing through a circular annular hole (through hole) on the hexagonal cylinder (bolt locking part 31); and an anti-drop spring (elastic member 35) having both ends passed through the cylindrical body 34 of the bolt shank and detachably mounted to the bolt shank.

Because the lifting body and the screw-in bolt can rotate mutually, when the screw-in bolt is completely fastened, the lifting body can freely rotate around the axis of the screw-in bolt, so that an included angle between the lifting ring 11 and the lifting hook is eliminated, and safe lifting is realized. For example, when a cabinet body is hoisted, the hexagonal cylinder of the bolt fastening mechanism is firstly placed in the inner hexagonal counterbore of the screwed bolt, the opening 321 of the locking ring 32 is reduced to keep elasticity, and the hexagonal cylinder and the inner hexagonal counterbore are ensured to be free from relative sliding to realize stable matching. At the moment, the lifting body is rotated, the circular lifting ring of the lifting body is contacted with the bolt fastening body, and the bolt fastening mechanism drives the screw-in bolt to rotate, so that the screw-in bolt is screwed on the cabinet body. After the bolt is completely fastened, the hexagonal cylinder is completely pulled out from the inner hexagonal counter bore, the lifting body is rotated according to the included angle between the lifting hook and the circular lifting ring of the lifting body to eliminate the included angle so as to realize connection, and the bolt nailing mechanism can be effectively prevented from falling off due to the existence of the anti-falling spring. After the included angle is eliminated, the hexagonal cylinder is placed in the hexagonal counter bore again, so that mutual rotation between the lifting body and the screwed bolt is avoided, and safe lifting is achieved.
