The balance lifting tool can be used to lift goods or workbenches, facilitating the transfer of goods or the high-altitude operation of workers. The balance lifting tool will be made of materials with appropriate weights and have sufficient strength and stability.
[0003] In the prior art, some hooks are movably sleeved under the balance lifting tool when in use, which are used to hang steel wires or goods. However, during the lifting process, the movable hooks are prone to swaying back and forth, resulting in unstable lifting of the goods and affecting the stability of the balance lifting tool during the lifting process.

One side of the side frame is connected with an extension frame. A fixed seat is fixed above the side frame. A chain is sleeved above the fixed seat. One end of the chain far from the fixed seat is sleeved with a first hanging ring. A second hanging ring is fixed below the side frame. The hook is sleeved below the second hanging ring. A reinforcing plate is connected at the included angle between the extension frame and the side frame.
[0006] Preferably, a connecting frame is slidably sleeved on the outer side of the extension frame. An extension mechanism is installed inside the connecting frame. One end of the extension frame is connected to the extension mechanism. A ball is installed at one end of the extension frame close to the connecting frame.
[0007] Preferably, the ball is slidably connected with the built-in groove of the connecting frame. A support frame is fixed below the side frame. A limiting mechanism is connected to one end of the support frame close to the hook, and one side of the limiting mechanism is connected to the hook.
[0008] Preferably, the extension mechanism includes a sliding rod, a first slider, a bidirectional lead screw, a second slider, and a turning handle. The bidirectional lead screw is installed inside the connecting frame through a bearing. A sliding rod is installed inside the connecting frame far from the bidirectional lead screw.
[0009] Preferably, one end of the bidirectional lead screw is connected with a turning handle. One end of the extension frame close to the connecting frame is fixed with a first slider and a second slider. The first slider is slidably sleeved on the sliding rod, and the second slider is threadedly sleeved on the bidirectional lead screw.
[0010] Preferably, the limiting mechanism includes a pull rod, a limiting spring, a limiting block, a rotating block and a limiting groove. One end of the support frame is installed with a rotating block through a movable shaft, and a limiting spring is arranged in the built-in groove of the rotating block.
[0011] Preferably, one end of the limiting spring is provided with a limiting block. One side of the limiting block is connected with a pull rod. The pull rod is located outside the rotating block. Limiting grooves are formed on both sides of the hook close to the limiting block.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. The present utility model is provided with a limiting mechanism. When in use, the hook is hung on the goods or the steel wire rope is hung on the hook as needed, and then the pull rod is pulled to one side, driving the limiting block to slide into the interior of the rotating block and extruding the limiting spring. Then, the rotating block rotates around one end of the support frame. When it rotates to the specified position, the pull rod is released, and the limiting spring rebounds, driving one end of the limiting block to insert into the limiting groove. The limiting block abuts against both sides of the hook, which can assist in limiting the hook. Without affecting the hanging of the goods by the hook, it can prevent the hook from shaking during the hoisting process, enhancing the stability of the present utility model during the hoisting process.
[0014] 2. The present utility model is provided with an extension mechanism. When in use, the turning handle is rotated to drive the bidirectional lead screw to rotate, so that the second sliders move away from each other on the bidirectional lead screw. At the same time, the second sliders drive the extension frame to slide to one side inside the connecting frame, thereby driving the first slider to slide on the sliding rod and driving the rolling balls to slide in the built-in groove of the connecting frame, enhancing the stability of the extension frame during the movement. The extension frame can drive the side frames to move to both sides, so as to quickly adjust the length of the present utility model to meet the needs of goods with longer lengths, improving the practicability of the present utility model.
