Expandable storage device for block chain technology

Abstract

The invention provides an expandable storage device for a block chain technology, relates to the technical field of expandable storage, and aims to solve the problems that an existing expandable storage device cannot be conveniently connected with an office table, cannot assist in binding a connecting circuit and cannot conveniently fix and use the expandable storage when applied to the office table. The expandable storage device comprises a main body, a mounting piece, a rotating piece and a clamping plate, wherein the main body is of an annular structure, the outer side of the top end of themain body is of an inclined structure, the mounting piece is mounted in the embedding opening of the main body, the side piece of the mounting piece is mounted in the clamping groove, and the auxiliary block of the clamping groove is inserted into the groove of the clamping groove. According to the invention, the rotating piece is used for driving the expanding piece to rotate for use, so that the rotating piece can be conveniently controlled to rotate and adjust; and the rotating piece can be connected with the main body, so that the main body can be conveniently inserted into a line hole ofthe office table, and the office table can be conveniently installed and used.

Description

technical field [0001] The invention belongs to the technical field of extended storage, and more specifically relates to an expandable storage device used in block chain technology. Background technique [0002] When the blockchain is stored, it usually needs to use the USB interface to insert a U disk or a mobile hard disk for data storage, but a single U disk or a mobile hard disk has limited capacity, and an expansion device is needed to move or move multiple U disks. Hard disk is connected. [0003] For example, the application number: CN201610696971.3 relates to a dust-proof computer USB expansion interface, including an expansion interface body, a USB plug mechanism, a dust-proof socket mechanism, a dust-proof cover mechanism, a PCB circuit board, and a USB jack. One side of the interface body is provided with a USB socket mechanism, the other side of the expansion interface body is provided with a dustproof socket mechanism, one side of the USB plug mechanism is pro...
