[0073] Understandably, during operation, the control system 5 regulates the second drive motor 421 to rotate clockwise. The second drive motor 421, through the cooperation of the second T-shaped commutator 423 and the two third shafts 424, drives the two drive gears 425 to rotate counterclockwise. Two limit rods 426 guide and limit the two drive gears 425, causing them to mesh with the rack 427 and slide the guardrail 41 upwards within the oblong hole 31. The guardrail 41 protects the operator above the work platform 3. After operation, the control system 5 regulates the second drive motor 421 to rotate counterclockwise. The second drive motor 421, through the cooperation of the second T-shaped commutator 423 and the two third shafts 424, drives the two drive gears 425 to rotate clockwise. The drive gears 425, through the meshing with the rack 427, slide the guardrail 41 downwards within the oblong hole 31 until the guardrail 41 slides below the work platform 3, preventing obstruction of personnel and vehicle passage.

[0074] like Figure 6 As shown, the work platform 3 is also provided with a storage channel 32. A cover plate 71 is provided above the storage channel 32, and a storage barrel 7 is fixedly connected below the storage channel 32. The storage barrel 7 is used to store tools and materials.

[0075] It is understandable that by opening a storage channel 32 on the work platform 3 and fixing a storage bin 7 below the storage channel 32, it is convenient for operators to retrieve or store tools and materials. A cover plate 71 is installed above the storage channel 32 to seal and protect the tools and materials stored in the storage bin 7. At the same time, the cover plate 71 prevents operators from accidentally stepping into the storage bin 7 during the operation, thereby improving the safety of the operation.

[0076] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0077] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
