[0021] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0022] Embodiment 1:

[0023] Combined with Figure 1 and 2 A mountain hook quick lifting tool comprises two connecting members 1; one end of each of the two connecting members 1 is equipped with a first pin shaft 2, and the other end is cross-overlapping and hinged through a second pin shaft 3. This structure enables the connecting member 1 to deflect around the second pin shaft 3, so that the first pin shaft 2 can be stably hung on the mountain hook.

[0024] In actual operation, firstly, the second pin 3 needs to be passed through the two connectors 1 and the lifting hole of the single-hole workpiece; then the connector 1 is adjusted to expand outward so that the two first pins 2 can be hung on both sides of the mountain hook. After the hanging is completed, the lifting operation can be carried out. When the workpiece is accurately placed at the specified position, only the second pin 3 needs to be removed to easily remove the single-hole workpiece and prepare for the next lifting task. It is not only simple in structure, convenient and quick to use, but also highly safe.

[0025] In order to ensure that the center of gravity of the single-hole workpiece is consistent with the center of gravity of the entire lifting system, and to avoid tilting or accidental falling during the lifting process, the attached Figure 2 As shown, each connector 1 is composed of two spaced connection plates, both ends of which are provided with through holes, wherein the top through hole is used to penetrate the first pin 2, and the bottom through hole is used for the second pin 3. The bottom of one connector 1 is inserted into the bottom of the other connector 1, so that the workpiece is located between the two, ensuring the alignment of the center of gravity.

[0026] Further design optimization is reflected in that a neck portion is provided at both ends of the first pin shaft 2, and the neck portion is provided with an annular groove, and the annular groove is used to install a limit member 4, such as a retaining spring or a limit baffle fixed by a screw. Such a design limits the possibility of the connecting plate moving axially along the first pin shaft 2, prevents the first pin shaft 2 from accidentally detaching from the connecting plate, and increases the overall safety and reliability.

[0027] For the second pin shaft 3, an axle pin structure is adopted, and its small end is locked by a capped locking pin 5 and a cotter pin 6; when the second pin shaft 3 is assembled with the single-hole workpiece and the connector 1, a capped locking pin 5 can be passed through the small end of the axle pin, and the capped locking pin 5 can be locked by the cotter pin 6, so that the second pin shaft 3 can be effectively locked to ensure that it will not slip out of the single-hole workpiece or the connector 1 due to axial movement. Once the second pin shaft 3 is assembled with the single-hole workpiece and the connector, the small end can be locked by the capped locking pin 5 and the cotter pin 6 to ensure its firmness.

[0028] In addition, considering the requirements of different working environments and workpiece characteristics, the spacing of the connector 1 and the position of the pin can be adjusted according to the specific application scenario, and even the first pin 2 and the second pin 3 of different specifications can be replaced, and the connector design can be adapted to various types of mountain hooks. These characteristics greatly improve the versatility and flexibility, enabling it to provide efficient and safe services in various complex industrial environments.

[0029] Embodiment 2:

[0030] In actual use, it was found that when a single-hole workpiece was hoisted to a predetermined position and the second pin shaft 3 was pulled out, the corresponding cross-overlapping ends of the two connecting parts 1 often separated unexpectedly, thereby delaying the hoisting operation of the next single-hole workpiece. In order to solve this technical problem, this embodiment is further improved.

[0031] Combined with Figures 2-3 , a mountain hook quick lifting tool, which is different from Example 1 in that, on the basis of Example 1, the corresponding cross-overlapping ends of the two connectors 1 are correspondingly hinged through the ring sleeve 7, and the second pin shaft 3 is movably inserted in the ring sleeve 7. Even if the second pin shaft 3 is completely pulled out, the corresponding cross-overlapping ends of the two connectors 1 are still restricted by the ring sleeve 7, and the hinged assembly relationship is maintained, and there will be no problem of accidental separation, which is conducive to the quick assembly operation of the connector 1 and the single-hole workpiece, and further improves the convenience.

[0032] It should be noted that, as shown in the accompanying drawings, in order to keep the center of gravity of the single-hole workpiece coaxial with the center of gravity of the mountain-shaped hook, there can be two ring sleeves 7, and the two ring sleeves 7 are arranged at intervals, and the corresponding connecting plates of the two connecting parts 1 are respectively hinged through the two ring sleeves 7.

[0033] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
