When the electric cylinder 22 is activated, the extension and retraction of the electric cylinder 22 can move the platform 10 up or down, which can be equipped with a secondary lifting platform, thereby adapting to operations that require secondary lifting, improving its work efficiency and utilization efficiency. When the electric push rod 29 is activated, the extension and retraction of the electric push rod 29 can move the bonding block 25 and the locking block 26 up or down, which can allow the bonding block 25 and the locking block 26 to enter or disengage from the bonding groove 28 and the locking groove 27, thereby driving the platform 10 to rotate, thus allowing it to adapt to operations in different directions.
