▎ 摘　　要

NOVELTY - The device has a heat conducting plate whose inner side is provided with a convex screw hole fixing part. Four corners of a connector switching plate (6) are fixed on the screw hole fixing part by a screw (8). A guide rail is fixed on the heat conducting plate. An electronic disk shell (32) is provided with a guide rail groove, where the electronic disc shell moves between a front panel of a machine box and the connector adapter plate along a guide rail. An upper surface of the heat conducting plate for facing to the electronic disk shell is adhered with a piece of graphene foam (5). A clamping door assembly (2) comprises a clamping door cover plate. USE - Floating mounting and dismounting device for a chuck e.g. electronic disk. Can also be used in mechanical engineering field. ADVANTAGE - The floating bush is installed on the chuck to the connector printed board, for making up for the chuck connector hard connection caused by manufacturing, assembly, vibration caused by the connector pin deformation damage by the product failure. The chuck, the chuck graphene the foam structure radiating design, using the new radiating material: foam graphene and corresponding structure form, the electronic disc radiating purpose. The new card door locking mechanism, the front side plate of the machine box is designed with a clamping door mechanism and the guide rail groove on the electronic disk shell. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a chuck floating mounting and dismounting device. 2Clamping door assembly 5Graphene foam 6Connector adapter plate 8Screw 31Hidden handle 32Electronic disk shell
