The invention discloses a transfer case. Mechanical claws are assembled in a case body of the transfer case, so that components can be clamped in the case body by the mechanical claws when transferred; clamping force can be applied to two reverse sides of each component by two claw bodies of the corresponding mechanical claw, accordingly, supporting effects can be realized for the components in the case body by the mechanical claws, and the components can be prevented from being toppled over along with jolting of the case body; the two claw bodies of each mechanical claw can be oppositely opened and closed from the periphery of the corresponding component to clamp the component when the two claw bodies of the mechanical claw are operated to clamp the component, so that the claw bodies of the mechanical claws can be prevented from frictionally sliding on the surfaces of the components when the components are clamped by the mechanical claws, and the surfaces of the components can be prevented from being scratched. The transfer case has the advantages that the components can be clamped under the oppositely opened and closed actions of the claw bodies of the mechanical claws and can be prevented from being toppled over owing to the component supporting effects of the claw bodies, and accordingly the problem that the front and rear surfaces of components can be easily suspended or scratched in transferring procedures in the prior art can be solved.
