[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] See also Figures 1 to 4 As shown, the utility model is a hook tool for lifting and lowering building materials, comprising a hand-held ring 1 and a storage tube 101 fixed on the top of its outer wall, a straight rod 102 is arranged inside the storage tube 101, a moving block 103 is sleeved on the outer wall of the straight rod 102, a through groove 1031 is opened at the center of the rear end face of the moving block 103, an adjustment component 2 is arranged on the top of the storage tube 101, the internal cross-section of the storage tube 101 is rectangular, an outer wall of the straight rod 102 is provided with an external thread, and the moving block 103 can slide on the outer wall of the straight rod 102 to adjust the position;

[0029] The adjusting assembly 2 includes a rotating block 201 and a gear ring 202 fixed at the center of its outer wall. A snap ring 203 is fixedly connected to the outer side of the bottom of the rotating block 201. The internal thread in the threaded hole wall of the inner wall of the rotating block 201 is meshed with the external thread on the outer wall of the straight rod 102 to play a transmission role. The snap ring 203 is located inside the annular groove 1011 to assist rotation and limit position.

[0030] An annular groove 1011 is provided on the outer side of the top of the storage tube 101, the bottom end of the straight rod 102 is fixedly connected to a limiting plate 1021, and the top of the outer wall of the straight rod 102 is fixedly connected to a hook body 1022, and the limiting plate 1021 plays a role in limiting the straight rod 102;

[0031] Slide grooves 1032 are provided on both sides of the rear end surface of the moving block 103, and a blocking hook 1033 is fixedly connected to the center of the outer wall of the moving block 103;

[0032] When the above arrangement is in use, the hand-held handle ring 1 can be used to utilize the straight rod 102 and the hook body 1022 to assist in lifting construction materials. The tool can operate the lifting object from a distance, avoiding the need to lift the object by hand nearby. Firstly, when lifting objects by hand, whether it is rising or falling, the wire rope itself will turn in a circle, driving the lifting object to have a rotating torque, which is often difficult for the human wrist to resist. In particular, when falling and hanging, the movement of objects has inertia, and the lifting object that seems to be slightly shaking may actually be very harmful. Secondly, the reaction time is increased in dangerous emergency situations, and the hook body 1022 can be released in time to avoid it. In addition, when the material accumulation area is in a relatively messy situation, when lifting steel bars and steel pipes, the hook body 1022 can easily pull the rope buckle from one side to the other, avoiding the team members from extending their hands or arms under the lifting object, especially if there are no pads under some materials. The on-site solution is often to lift one end first, and then lift the The wire rope is introduced and tied from below, but this temporary lifting method of lifting one end is often not firm enough and is very easy to slip. At this time, blindly extending hands or arms under the hanging object is likely to cause accidental injury. The tool can easily and quickly pull the lifting rope to avoid accidents. When auxiliary lifting of materials at a long distance is required, the toothed ring 202 is rotated, and the toothed ring 202 is forced to rotate under the assistance of the retaining ring 203 and the annular groove 1011. The rotation of the toothed ring 202 will drive the inner rotating block 201 to rotate, and the internal thread in the threaded hole wall on the inner wall of the rotating block 201 is meshed with the external thread on the outer wall of the straight rod 102. Therefore, when the rotating block 201 rotates, it will push the straight rod 102 to move toward the outside of the storage tube 101, so that the length of the straight rod 102 extending out of the outside of the storage tube 101 can be adjusted, which is convenient for the staff to adjust according to the actual usage, with high work efficiency and resource saving.

[0033] Among them Figure 1 , 5As shown, a limit assembly 3 is arranged inside the through slot 1031, and the limit assembly 3 includes a push-pull plate 301 and a linkage rod 302 fixed at the center position of the upper surface thereof, a push block 303 is fixedly connected to the top of the linkage rod 302, and a connecting rope 304 is fixedly connected to the center position of the inner wall of the push block 303, and the push-pull plate 301 and the push block 303 are connected by the linkage rod 302, which plays a role of connecting transmission;

[0034] The front end surface of the push block 303 is fixedly connected with a slide plate 3031 on both sides of the edge, and the slide plate 3031 is located inside the slide groove 1032. Under the action of the slide plate 3031 and the slide groove 1032, the push block 303 can be assisted to move and play a role of limiting.

[0035] The other end of the connecting rope 304 passes through the sliding hole at the center of the outer wall of the outer plate 305 and is connected to the outer wall of the movable plate 306. The inner wall center of the movable plate 306 is fixedly connected with a connecting rod 308. The push block 303 and the movable plate 306 are connected by the connecting rope 304, which plays a role of connecting transmission.

[0036] The other end of the connecting rod 308 passes through the through hole at the center of the outer wall of the fixed plate 307 and is connected to the block 3010. A spring 309 is sleeved on the outer side of the outer wall of the connecting rod 308. The movable plate 306 and the block 3010 are connected through the connecting rod 308 to play a role in connecting transmission.

[0037] The spring 309 is located between the fixed plate 307 and the block 3010. The outer wall of the outer plate 305 and the fixed plate 307 are fixed on the inner wall of the through groove 1031. The elastic performance of the spring 309 drives the block 3010 to move.

[0038] When the above arrangement is in use, the push-pull plate 301 is moved upward and downward, and the upper surface of the push-pull plate 301 is connected to the push block 303 through the connecting rod 302. Therefore, when the push-pull plate 301 moves, the push block 303 is driven to move under the action of the connecting rod 302, so that the push block 303 slides under the auxiliary action of the slide plate 3031 and the slide groove 1032, and the inner wall of the push block 303 is connected to the moving plate 306 through the connecting rope 304. Therefore, when the push block 303 moves, the moving plate 306 is driven to move under the action of the connecting rope 304, and the inner wall of the moving plate 306 is connected to the block 3010 through the connecting rod 308. Therefore, when the movable plate 306 moves, the block 3010 will be driven to move under the action of the connecting rod 308, and the spring 309 will be squeezed, so that the block 3010 can be moved into the through groove 1031, and the limiting effect of the block 3010 on the external thread of the outer wall of the straight rod 102 can be cancelled. Then, by applying force to the push-pull plate 301, the position of the movable block 103 on the outer wall of the straight rod 102 can be adjusted, and then the position of the blocking hook 1033 can be adjusted according to the building materials, and it can cooperate with the hook body 1022 to limit the building materials, play a protective role, and improve safety performance.

[0039] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
