The retractable automatic clamping device clamps the curbstone, thereby hoisting the curbstone.

[0042] In this embodiment, a locking mechanism is provided on the universal wheel, and the universal wheel can be locked by the locking mechanism to prevent the device from moving during operation, thereby increasing the overall reliability of the device.
