In this step, a Z-shaped connecting block 42 is fixed in the middle of the sliding frame 24, and the end of the Z-shaped connecting block 42 slides through the clamping groove, while a pulling force is applied to the sliding frame 24, thereby improving the stability of the sliding frame 24 when moving. When the Z-shaped connecting block 42 moves, it pushes the piston 51 to slide in the cylinder 5, enabling the Z-shaped connecting block 42 to slide stably. When the position of the Z-shaped connecting block 42 is fixed, the piston 51 is fixed in the cylinder 5 due to the air pressure inside the cylinder 5, thereby fixing the position of the Z-shaped connecting block 42. In this step, an additional cylinder piston device is added when the Z-shaped connecting block 42 moves, thereby improving the stability of the Z-shaped connecting block 42 when moving, and reducing the phenomenon of the Z-shaped connecting block 42 deviating during use of the lifting appliance. When the lifting hook 17 is not connected to the transformer, the third spring 6 is in a compressed state. When the lifting hook 17 is connected to the transformer, the third spring 6 is stretched. When the lifting hook 17 is in a straight state, the stretching state of the third spring 6 is relaxed to a certain extent, but it is still stretched. When the lifting appliance is used, the third spring 6 is stretched, which pulls the pulling block 105. The elastic action of the third spring 6 can buffer the stress of the pulling block 105 when moving. In this step, the third spring 6 buffers the stress of the pulling block 105 when moving, thereby improving the stability of the pulling block 105. When the fourth spring 7 is compressed, the fourth spring 7 is released when the sliding frame 24 moves, thereby generating a force on the sliding frame 24. When the position of the sliding frame 24 is fixed, a pushing force is applied to the sliding frame 24, thereby stabilizing the position of the sliding frame 24. In this step, the fourth spring 7 generates a pushing force on the sliding frame 24 after the sliding frame 24 moves and is fixed, thereby reducing the deviation of the sliding frame 24 and improving the stability of the sliding frame 24.
