During the cabin unit hoisting process, to ensure the stability of the prefabricated cabin, different-sized hoists must be used for each prefabricated cabin. This often requires multiple sets of hoists of different sizes, making transportation inconvenient and the workload of hoisting changes considerable, impacting work efficiency.

[0008] As an optimization, the upper end of the clamping arm is hinged with a clamping plate through a hinge axis C extending axially along the hinge axis B; the clamping surface of the clamping arm is adapted to the prefabricated cabin through the clamping plate to prevent damage to the prefabricated cabin when an angle is formed between the clamping arm and the prefabricated cabin.
[0009] As an optimization, the lower end of the clamping plate is connected to the clamping arm through a return spring B, and the hinged part of the return spring B and the clamping arm is located below the hinge axis C; the return spring B ensures that the clamping plate in the idle state is in a fixed position, which facilitates the clamping of the prefabricated cabin during work and saves manpower.
[0010] As an optimization, a through hole extending axially along the hinge axis B is provided on the clamping jaw, the hinge axis B is passed through the through hole, and the clamping jaw is slid onto the hinge axis B through the through hole; the axial position of the hinge axis A of the clamping jaw is adjusted through the through hole and the hinge axis A, so as to clamp prefabricated cabins of different sizes.

[0012] As an optimization, anti-slip grooves are provided on the inner side of the clamping plate; the anti-slip grooves increase the friction between the clamping plate and the prefabricated cabin, preventing the claws from sliding on the prefabricated cabin.
[0013] As an optimization, a 90° angle is formed between the support plate and the clamping arm; the prefabricated cabin can be better clamped by forming a 90° angle between the support plate and the clamping arm.
