When it is necessary to operate on the blades, it can be assembled to form a large square maintenance platform to meet different application scenarios. Although this device can be used for blade maintenance, there are inconveniences in blade maintenance with the square frame structure. The main reason is that the blade needs to be placed between the square structures and then the maintenance starts, resulting in inconvenient maintenance and low maintenance efficiency.
