Referring to fig. 2, fig. 2 is an enlarged view of a in fig. 1. The hanger unit 200 includes a positioning hanger 300 and a fastening hanger 400, and both the positioning hanger 300 and the fastening hanger 400 are fixedly connected to the rack body 100. The positioning hanger 300 is used for supporting the product 600, the fastening hanger 400 is used for providing an elastic force to the product 600 in a direction away from the positioning hanger 300, and the product 600 is hung on the hanger unit 200 under the action of the elastic force. Referring to fig. 3, the positioning hanger 300 and the fastening hanger 400 are vertically arranged, and when the product 600 is not hung, the portion of the fastening hanger 400 contacting the connecting hole 590 of the product 600 is inclined in a direction away from the positioning hanger 300, specifically, when the embodiment shown in fig. 3 is used, the free end 430 of the fastening hanger 400 is inclined upward. And, after the product 600 is hung, referring to fig. 4 and 5, the portion of the fastening hanger 400 for contacting the coupling hole 590 of the product 600 is elastically deformed in a direction to approach the positioning hanger 300. Thus, the fastening hanger 400 is in surface contact with the contact part of the inner side of the connecting hole 590 of the product 600, the stress at the connecting hole 590 of the product 600 is improved, and the stress area is increased, so that the connecting hole 590 is not curled. Further, the degree of the elastic deformation is such that a portion of the fastening hanger 400 for contacting the connection hole 590 of the product 600 is horizontally disposed.
