[0002] A mobile memory, as an external storage device, has the characteristics of being portable, easy to disassemble and assemble, and large in capacity, and is widely used in individuals, enterprises and various digital devices. It mainly depends on its internal controller and storage chips. The controller is the core component of the removable memory, responsible for managing data transmission, storage and reading. It includes a processor, a memory manager and firmware, which are responsible for controlling the data flow, tracking the data in the memory and allocating new storage locations, as well as controlling data transmission and detecting the status of the device. The storage chip is a key component in the removable memory. Common types of storage chips are flash memory and DRAM. Flash memory can store data persistently and retain data even when power is off, and has a relatively fast read and write speed; while DRAM has a faster read and write speed, but is a volatile memory and will lose all data after power off.

[0003] In the existing mobile memories, there is usually a memory main body, and a protective cover is hinged on one side of the memory main body. The protective cover plays a role in protecting the memory main body when it is not in use. Another way is to directly set a protective cover on one side of the memory main body. When using these two methods, in the first hinged method, when the memory main body drops, since the memory main body and the protective cover are hinged, loosening may occur. And in the other method, since the protective cover is directly covered on one side of the memory main body, the main supporting force is realized through the deformation extrusion force of the protective cover, and loosening will also occur when the memory main body drops.

[0004] Therefore, it is necessary to provide a new rotatable and telescopic mobile memory to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a rotatable and telescopic mobile memory.

One end of the clamping block extends into the activity groove. One end of the clamping block close to the activity groove is fixedly connected to one end of the first spring. The end of the first spring far from the clamping block is fixedly connected to one side inside the activity groove. The end of the clamping block far from the first spring is arc-shaped.

[0008] Preferably, the pushing device includes a driving assembly, a supporting disc and a limiting ball. One end of the driving assembly extends into the clamping column. One end of the driving assembly close to the clamping column is fixedly connected to the bottom end of the supporting disc. The side of the supporting disc far from the driving assembly is fixedly connected to the bottom end of the memory body. The limiting ball is fixedly arranged on one side of the supporting disc. The side of the limiting ball far from the supporting disc is arranged in a spiral sliding groove provided on the inner side wall of the clamping column.

[0009] Preferably, the driving assembly includes a limiting group and a rotating rod. The limiting group is arranged at the bottom end of the clamping column. The rotating rod is arranged in the limiting group. The upper end of the rotating rod is fixedly connected to the bottom end of the supporting disc.

[0010] Preferably, the limiting group includes a rotating frame and a plurality of limiting plates. The rotating frame is movably arranged at the bottom end of the protective frame. The plurality of limiting plates are evenly and fixedly arranged inside the rotating frame. One ends of the plurality of limiting plates far from the rotating frame are movably arranged in a plurality of limiting grooves provided on the rotating rod.

[0011] Preferably, a second spring is fixedly connected to the inner bottom wall of the installation groove.

[0012] Preferably, the number of the limiting plates is specifically four. One ends of the four limiting plates far from the rotating frame are movably arranged in the four limiting grooves provided on the rotating rod.

[0013] Compared with the related art, the rotatable, telescopic and movable memory provided by the present utility model has the following beneficial effects:

[0014] By setting the clamping post, the clamping block and the first spring, during use, the clamping post at the bottom of the cover body extends into the installation groove on the memory body. In this process, the clamping block will first come into contact with the upper end of the protection frame. The protection frame squeezes the clamping block, causing the clamping block to enter the inside of the clamping post, and at the same time, the first spring will be compressed until the clamping block completely enters the inside of the clamping post. At this time, the driving force of the first spring causes the clamping block to pop out, completing the fixation of the cover body. Compared with the traditional fixation method by the deformation extrusion force of the cover body, this method realizes a firm fixation of the cover body, reduces the loosening situation that may occur when the memory body drops, and to a certain extent ensures the service life of the device.
