According to the current trend of Internet cloud technology and the Internet of Things, the server technology of computers and industrial computers is growing at a rapid pace. Its development trend is mainly towards strong computing functions, fast speed and small size. In addition, many electronic devices or equipment will use computers to control their actions or execute functions, making computers occupy an extremely important position. When processing huge amounts of data, the servers of commercial computers urgently need high-density and large amounts of memory storage devices (such as hard drives, solid-state drives, optical drives, or burners, etc.) to store and read data. Therefore, a large amount of memory storage devices are usually placed inside computer hosts, server cases, storage or electronic cabinets, etc. to increase storage capacity.

Furthermore, since a general computer mainframe, server case, storage or electronic cabinet has a large number of memory storage devices, when the user performs maintenance or replacement operations on each memory storage device, the replacement speed between the memory storage devices installed in the case must be simpler and faster, and the assembly structure and component manufacturing costs must also be taken into consideration to meet the cost and demand of the large number of memory storage devices. In addition, the case must be considered for long-term use. Considering the stability of the whole system and the convenience of maintenance and replacement, and facilitating user operation, thereby reducing downtime and manpower losses, multiple C-type clamps are often used to clamp and fix two plates located at the chassis. However, the C-type clamp must first be screwed to adjust the distance between the movable clamp and the fixed clamp. When the distance is larger than the outer surface of the two plates, it is then placed on the outside of the two plates and the screw is turned to reduce the distance between the movable clamp and the fixed clamp for locking. Although the above method can effectively fix the two plates, it takes a lot of time to turn the screws back and forth to enlarge and then reduce the distance. Moreover, many C-type clips are needed to fix the four sides of the two plates. It takes a lot of time to separate the two plates and disassemble the C-type clips for maintenance. For a server room with a large number of chassis, it is obviously not economical. Furthermore, the screws of the C-type clips do not have any locking mechanism, so it is easy for the screws to loosen and cannot be fixed firmly. The above-mentioned deficiencies must rely on the relevant manufacturers engaged in this industry to develop and improve.

Therefore, in view of the above problems and deficiencies, the inventor collected relevant information and, after multiple evaluations and considerations, designed the invention of this tightening and fixing device.

The main purpose of the present invention is to provide a kind of abutment fixing device, comprising: a positioning seat, wherein two sides of the top plate of the seat each extend downwardly with a side plate and the top plate has a screw groove, the two side plates are provided with a buckle portion protruding toward one side and an operation panel is formed on the other side opposite to the buckle portion; a fixing member, which comprises a head and a rod body locked in the screw groove, and a positioning end extends from the end of the rod body; a holding mechanism, which comprises a base with a storage chamber inside, the storage chamber is used to accommodate a turning body at the bottom side of a movable seat and the movable seat can be rotated on the base, and a connecting portion with a positioning groove inside extends above the turning body, and the positioning end of the fixing member is inserted into the positioning groove and fixed. According to the above, when the movable panel provided at the chassis is placed on the outer edge of the protrusion on one side of the base and is to be fixed, the buckle parts of the multiple abutting fixing devices are obliquely extended into the corresponding coupling holes provided on the edge of the protrusion; at the same time, the base of the abutting mechanism is connected with the movable base at an inclined angle, and force is applied to the operation panel to rotate the positioning seat from the inclined state to the horizontal state and make the abutting surface of the base abut against the surface of the movable panel, and then the fixing part is rotated to make the abutting surface of the base move toward the surface of the movable panel, so that the movable panel and the base are tightly fixed, and the fixing part is locked through the elastic positioning part assembled on the operation panel, so as to achieve the purpose of quick assembly, disassembly and locking of the base and the movable panel without loosening.

The secondary purpose of the present invention is that the fixing part has a positioning ring with multiple cross grooves formed on the surface between the head and the rod, and a turntable is formed by plastic injection molding at the head and the positioning ring. The center of the turntable has a receiving groove for accommodating the head and an annular inner wall covering the outer edge of the positioning ring. The edge of the turntable is recessed inward to form multiple limit grooves.

Another purpose of the present invention is that the top surface of the head of the fixing part is further provided with an operating groove for inserting a preset hand tool into the operation, and the operating groove is a straight, cross, plum blossom or hexagonal groove.
