Waterproof computer hard disk fixing device

The invention discloses a waterproof computer hard disk fixing device. The invention relates to the technical field of hard disk fixing devices. An existing hard disk fixing device cannot fix hard disks of different sizes. The heat dissipation efficiency is low; meanwhile, dust cannot be effectively prevented. The fixing device comprises a device body and a mobile device, wherein an isolation plate is arranged at the top of the device main body; a fixed tray is arranged at the bottom of the device main body; t. The bottom of the fixed tray is fixedly connected with the upper end of an elasticrod; and the moving device penetrates through the front wall of the fixed tray and comprises a control knob, a rotating gear, a rotating rod and a bearing, hard disks of different sizes can be effectively fixed, meanwhile, heat can be effectively dissipated, dust is prevented from entering the hard disks, meanwhile, the buffering effect is achieved, and the popularization value is achieved. 本发明公开了种防水型计算机硬盘固定装置，涉及硬盘固定装置技术领
