[0024] In the first embodiment, the rotating shaft of the roller 31 extends into the adjustment box 32, the inner wall of the card slot 33 is provided with uniform card teeth, which mesh with the card teeth on the card block 35, and the two sides of the fixing frame 34 are stuck in the slide slot and move left and right in the slide slot.

The filter 47 can effectively prevent dust, impurities and other pollutants in the air from entering the interior of the device, protecting the various components of the hydraulic system from pollution and extending their service life. At the same time, the airflow generated by the rotation of the blades 46 driven by the motor 45 can continuously cool the hydraulic oil tank 41 after a long period of blowing, ensuring that the hydraulic system works stably within an appropriate temperature range and improving the reliability and stability of the entire system.

[0026] In the second embodiment, the lifting frame 12 is connected by screws, the bottom of the lifting plate 3 is installed on the top of the lifting frame 12, the bottom end of the hydraulic pump 2 is fixed to the base 1 through the mounting frame, support plates are installed on both sides of the lifting plate 3, the roller 31 is installed in the middle of the support plate, the rotating shaft of the roller 31 passes through the support plate and is fixed with screws, a row of buttons are evenly installed above the control box 4, an oil inlet is provided on the surface directly above the hydraulic oil tank 41, and a push-pull rod is fixed above the base 1.

[0027] Specifically, the lifting frame 12 is connected by screws. This connection method not only ensures the stability of the lifting frame 12 structure, but also facilitates disassembly and maintenance when needed. The top of the lifting frame 12 is installed at the bottom of the lifting plate 3, providing reliable support and lifting power for the lifting plate 3. The bottom end of the hydraulic pump 2 is fixed to the base 1 through a sturdy mounting bracket to ensure that the hydraulic pump 2 will not shake or displace during operation, providing a stable power source for the lifting function of the entire device. Support plates are carefully installed on both sides of the lifting plate 3. These support plates provide a stable installation position for the roller 31. The roller 31 is installed in the middle of the support plate, and its rotating shaft passes through the support plate and is fixed with screws. The roller 31 is fixed with a wire, and this fixing method enables the roller 31 to rotate stably between the support plates, and is also convenient for disassembly and replacement when needed. A row of buttons are evenly installed above the control box 4, which can facilitate the operator to perform various operations and controls on the device. An oil inlet is provided on the surface directly above the hydraulic oil tank 41, which is convenient for adding hydraulic oil to the hydraulic oil tank 41 when needed. A push-pull rod is also fixed above the base 1, and this push-pull rod provides a convenient operating position for the operator. Through the push-pull rod, the operator can more easily push the entire device to move between different work sites, thereby improving the maneuverability and ease of use of the device.

[0028] Working principle: First, the hydraulic pump 2 acts as a power source, and transmits power to the lifting frame 12 through the connected telescopic rod. When the hydraulic pump 2 is working, the hydraulic oil pushes the telescopic rod to perform telescopic movement under the action of pressure. The telescopic rod is connected to the horizontal axis of the lifting frame 12. As the telescopic rod is extended or shortened, the lifting frame 12 is lifted and lowered. The lifting plate 3 is installed on the top of the lifting frame 12, thereby driving the lifting plate 3 to move up and down. When it is necessary to fix the roller 31 to prevent the sign from falling off, the operator turns the turning handle of the adjusting screw 36 on the adjusting box 32, and the adjusting screw 36 is pushed inward, pushing the fixing frame 34 to move in the slide grooves on both sides of the adjusting box 32. The blocking block 35 on the fixing frame 34 then approaches the rotating axis of the roller 31 and finally gets stuck in the slot 33 on the rotating axis. Because the inner wall of the slot 33 and the blocking block 35 have mutually meshing teeth, the roller 31 is firmly fixed and cannot rotate. When it is necessary to remove the sign, the adjusting handle is reversed, and the adjusting screw 36 is withdrawn outward, driving the fixing frame 34 and the block 35 leave the slot 33, allowing the roller 31 to rotate, making it easier for workers to remove the sign. When the motor 45 is running, it drives the blades 46 installed on its rotating shaft to rotate. The rotation of the blades 46 generates airflow, which is sucked in from the air inlets 42 on both sides of the control box 4. At the end of the support shell 43, the air is filtered by the filter 47 to remove pollutants such as dust and impurities in the air. The filtered air continues to blow forward to the hydraulic oil tank 41. After a long period of blowing, the hydraulic oil tank 41 is continuously cooled, ensuring that the hydraulic system operates within a suitable temperature range and improving the stability and reliability of the system. The universal wheels 11 under the base 1 allow the entire device to be easily moved to different work sites. The operator can push the device using the push-pull rod installed on the top of the base 1. The row of buttons on the top of the control box 4 are used to perform various operations and controls on the device. When hydraulic oil needs to be added to the hydraulic oil tank 41, it can be added through the oil inlet on the surface directly above it. At this point, the entire workflow is completed.
