It uses batteries as a green and clean power source, has the characteristics of low noise and environmental protection, and is particularly suitable for occasions with strict environmental requirements. Its core advantage lies in being equipped with a liftable work platform, which not only allows the operator to complete aerial work tasks in a safe and stable environment, such as outdoor decoration, building maintenance, gardening pruning and cargo handling, but also demonstrates excellent maneuverability in a small space with its tricycle structure. The model has different load capacities depending on the design, and can meet multiple work load requirements. It also greatly simplifies the operation process and improves work efficiency through a simple operation interface and even remote control technology.

[0003] The problem with the above technology is that in the current application scenarios of electric lift tricycles, although they provide great convenience for high-altitude operations and cargo transportation, they still face a significant challenge, that is, during transportation, due to the lack of effective cargo fixing or clamping mechanisms, the risk of cargo falling becomes a problem that cannot be ignored. Such incidents may not only cause damage to the cargo and cause economic losses, but may also cause safety hazards and affect operational efficiency and safety. Especially when the vehicle encounters bumpy roads, sharp turns or emergency braking during driving, the lack of stable cargo fixing measures will increase the possibility of cargo shifting or even falling off.

[0024] The working principle of this utility model:

[0025] When in use, first, the operator gently places the goods on the surface of the loading plate to ensure that the goods are stable and centered, and then pulls the handle upward to separate the positioning block from the positioning groove. The realization of this step allows the turntable to rotate freely and is no longer restricted by the positioning block. At this time, it is only necessary to turn the handle to drive the movement of the turntable. The lower end of the turntable is closely connected with the fixed rod. During the rotation, the fixed rod will tighten and wind the steel cable. The steel cable is a key component connecting the turntable and the support rod at the bottom of the disc. During the tightening and winding process, the support rod is driven to rotate through pulling. The rotation of the support rod further drives the rope wound on the slide groove on the surface of the disc to shrink. The contraction of the rope makes the originally loose rope become tight. In the process of tightening the rope, the slider will be dragged to move. The slider is closely connected to the connecting block. When the slider moves, the connecting block will also move accordingly. The movement of the connecting block causes the clamping plates to move to both sides, so that the distance between the clamping plates becomes larger, making it easier to place the goods. When the connecting block at the bottom of the clamping plate slides to the top in the limit groove, the goods can be placed between the two clamping plates. Next, the operator pulls the clamping block on the clamping plate to make the clamping block move inward under the action of the spring. As the clamping block moves, the clamping force of the clamping plate on the goods gradually increases until the goods are clamped. At this time, the goods are tightly surrounded by the clamping plate and the clamping block, thereby further fixing the goods. After the goods are fixed, push the handle downward to make the positioning block contact the positioning groove again, so that the position of the clamping plate can be fixed. Finally, when the goods are stably fixed on the loading board, the operator can move the electric tricycle to the designated place and stop it. Then, by starting the air pump, the loading board is lifted. The operation of the air pump causes the loading board to rise, driving the goods to rise together until the required height is reached. At this time, the goods have been safely and firmly fixed on the loading board, and subsequent transportation or loading and unloading work can be started.
