[0030] The moving component 32 includes a cross beam 322, which is fixedly installed on the inner bottom of the support column 1. A sliding rod 321 is slidably installed inside the book-searching cross beam 322, and a hinge seat 323 is rotatably installed on the outer side of the sliding rod 321. A telescopic rod 324 is fixedly installed on the end of the hinge seat 323 away from the sliding rod 321, and a universal wheel 325 is fixedly installed on the end of the telescopic rod 324 away from the hinge seat 323. A motor 2 328 is fixedly installed on the inner bottom of the support column 1, a rack 327 is fixedly installed on the output end of the motor 2 328, a gear 326 is fixedly installed on the output end of the rack 327, and the rack 327 is meshed on the outside of the gear 326, so that the support mode of the device can be switched.

[0031] There are two cross beams 322, and both cross beams 322 are provided with sliding grooves, the slide rod 321 is slidably installed inside the slide grooves, the rack 327 is fixedly installed at the bottom of the slide rod 321, and there are four telescopic rods 324, and the four slide rods 321 are rotatably installed inside the support column 1. A rectangular through hole is provided at the bottom of the support column 1, and the telescopic rod 324 is rotatably installed inside the rectangular through hole to drive the support switching of the device.

[0032] The lifting assembly 31 includes a base plate 312, which is fixedly installed on the inner wall of the support column 1. A motor 313 is fixedly installed on the top of the base plate 312. A threaded shaft 316 is fixedly installed on the output end of the motor 313. A sliding frame 315 is threadedly installed on the outer side of the threaded shaft 316. A lifting rod 314 is rotatably installed on the outer side of the sliding frame 315. A bottom slide rail 317 is fixedly installed on the top of the base plate 312. A rectangular fixed plate 311 is rotatably installed on the outer side of the top of the lifting rod 314, which can adjust the device for lifting and lowering.

[0033] Embodiment 2:

[0034] See also Figure 4 In combination with the first embodiment, it is further obtained that the lifting rod 314 and the sliding frame 315 are both slidably installed on the inner side of the bottom slide rail 317, a slide groove is provided inside the bottom slide rail 317, and the lifting rod 314 is slidably installed inside the slide groove to limit the lifting and lowering of the device.

[0035] The supporting mechanism 2 includes an auxiliary rod 22, which is fixedly installed on the top of the base plate 312. A lifting plate 23 is fixedly installed on the top of the auxiliary rod 22. A protective fence 21 is fixedly installed on the top of the lifting plate 23.

[0037] In actual operation, when this device is used, when it is necessary to perform aerial work, the device needs to be moved to the designated position in advance, by energizing the motor 2 328. When the motor 2 328 is energized, the gear 326 is driven to rotate by being fixedly installed with the output end gear 326. When the gear 326 rotates, it drives the rack 327 to move in the opposite direction by meshing with the external rack 327. When the rack 327 moves in the opposite direction, it moves the slide bar 321 by being fixedly installed with the slide bar 321 to move in the opposite direction. In this way, the hinge seat 323 is driven to rotate by the opposite movement of the rack 327. When the hinge seat 323 rotates, the universal wheel 325 can contact the ground, thereby supporting the support column 1, which is more convenient and labor-saving.

[0038] When it is necessary to perform aerial work, a person stands on the top of the lifting platform 23 and energizes the motor 1 313. When the motor 1 313 is energized, the screw shaft 316 is driven to rotate by being fixedly installed with the output end screw shaft 316. When the screw shaft 316 rotates, the screw shaft 316 is driven to move by being threadedly installed with the external sliding frame 315. In this way, the lifting rod 314 can be supported by the movement of the sliding frame 315, and the rectangular fixed plate 311 can be lifted and lowered. In this way, the person can complete the aerial work. The protective fence 21 fixedly installed on the top of the lifting platform 23 can protect the person and prevent the person from falling.

[0039] When working at high altitude, it is necessary to reverse drive motor 2 328 to make the universal wheel 325 separate from the ground, so that the ground can be supported by support column 1 so that the device will not shake. When high altitude work is required in other places, there is no need for personnel to come down from the lifting platform 23. The universal wheel 325 can be directly driven by drive motor 2 328 to contact the ground and move during work, thereby saving the time required for personnel to go up and down repeatedly, thereby improving work efficiency.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
