摘要： A levering device includes a coupling block, a gripper, an operating rod, and a constraint sleeve. The coupling block includes a coupling chamber, two guide slots in communication with the coupling chamber, an extension rod, and an axial hole axially cut through the extension rod in communication with the coupling chamber. The operating rod being axially movably inserted through the axial hole into a bearing chamber of a housing of a motor-driven water lifting device to stop against respective one end of a wheel axle of the motor-driven water lifting device. The gripper is attachable to the two guide slots of the coupling block and includes two gripper blocks and two claw bars respectively connected to the gripper blocks. The constraint sleeve is sleeved onto the coupling block to stop the two claw bars in the respective the guide slots.
