One end of the third upright 63 is connected to the second upright 62, and the other end is movably sleeved on the adjusting rod 22 and fixed by the positioning member 23. The assembly of multiple uprights can reduce the space occupied by a single component and facilitate disassembly, transportation or storage. In other embodiments, the number of uprights can be increased or decreased as needed, such as movably sleeved on the bottom of the second upright 62 on the adjusting rod 22 and fixed by the positioning member 23.

[0031] In another embodiment, the boom 3 is telescopic to adjust its length. The boom 3 includes multiple interlocking crossbars, a support frame connected to a corresponding crossbar, and a lifting cable 1 slidably connected to at least one crossbar. The telescopic boom 3 improves the installation flexibility of the portable lifting device. When the ground installation environment is limited or the adjustable base 2 is located far from the building side wall 9, the object to be lifted 10 can be moved to a designated position by adjusting the length of the boom 3.

[0032] In another embodiment, the stand can also be rotatably connected to the boom 3, which can be unfolded to lift objects or folded to reduce space occupation, which not only improves applicability but also facilitates movement or storage.

[0033] In this embodiment, the lifting section also includes a positioning wheel assembly 4, through which the lifting line 1 is slidably connected to the support body. In this embodiment, multiple positioning wheel assemblies 4 are used to form a multi-stage steering positioning system for the lifting line 1. Specifically, a positioning wheel assembly 4 is located at the intersection of the upright and the boom 3, i.e., at the intersection of the first upright 61 and the boom 3. A positioning wheel assembly 4 is also located at the end of the boom 3 furthest from the upright. One end of the lifting line 1 is wound around the control component, and the other end of the lifting line 1 passes through multiple positioning wheel assemblies 4 sequentially before connecting to the object 10 awaiting lifting in the housing. Using multiple positioning wheel assemblies 4 reduces the risk of the lifting line 1 swaying or getting stuck.

[0034] In this embodiment, the control component includes a spool 51 rotatably connected to the support body, a crank handle 52 on the spool 51, and a lifting line 1 wound around the spool 51. In this embodiment, the control component also includes a spool frame 53, which is connected to the support body. Specifically, the spool frame 53 is connected to the second upright 62, the spool 51 is rotatably connected to the spool frame 53, and the crank handle 52 is connected to the spool 51 for driving.

[0035] In this embodiment, the lifting line 1 is also equipped with a hook 7 at the end for lifting, which facilitates the lifting and installation of objects such as boxes.

[0036] The method of using this utility model includes the following steps:

[0037] Adjust the height of the top of the bracket body and fix it in place via the adjustable base 2;

[0038] The lifting line 1 is connected to the object 10 to be lifted, and the object 10 is pulled up by the control component.

[0039] The working process of this embodiment is as follows:

[0040] Move the portable lifting device to the predetermined position and place the support body on the building base plate 8 via the adjustable base 2;

[0041] Based on the requirements of the building floor height and lifting height, adjust the length of the support body, align the positioning hole with the matching adjustment hole 621 and insert the adjustment bolt 611 to achieve coarse adjustment of the support body length. When the support body length needs fine adjustment, the positioning part 23 can be rotated to finely adjust the height of the top of the support body so that the boom 3 corresponds to the building top plate.

[0042] Connect the hook 7 to the object 10 to be lifted, turn the crank 52 to make the box lift the object 10 rise to the specified height.

[0043] This utility model is reusable, saves costs, has a simple structure, is easy to carry and install, and its structure is adjustable to suit complex installation environments and requirements. It can reduce the need for boxes, improve labor costs and construction efficiency during the installation process, reduce the physical exertion of installers, and ensure construction safety.

[0044] Example 2:

[0045] In this embodiment, an illumination element 71 is also included. The illumination element 71 is connected to the support or lifting part, such as by connecting the illumination element 71 to the hook 7 to suit different installation environments. The illumination element 71 can be made of LED light, which is easy to assemble and has low cost.

[0046] In this embodiment, the control component further includes a crank limiter 521, which is rotatably connected to the spool frame 53. Preferably, the spool frame 53 has an accommodating space to accommodate the crank limiter 521. When the crank 52 is rotated to lift an object, the crank limiter 521 is positioned within the accommodating space. When the object 10 to be lifted is raised to a predetermined height, the crank limiter 521 can be rotated to extend it and prevent the crank 52 from rotating back. This dual protection improves the safety of the construction process.

[0047] In this embodiment, the lifting part also includes an auxiliary lifting strap, which is detachably connected to the hook 7. The auxiliary lifting strap can be used to wrap around the outside of the box and cooperate with the hook 7 to improve lifting stability and prevent the box from tilting.
