The invention belongs to the technical field of sale cabinet equipment, and particularly relates to a sale cabinet convenient to observe for sale of computer software discs. For solving the problems of inconvenience in observation, not high degree of automation and low safety factors, the following scheme is proposed: the sale cabinet comprises a sale cabinet body, fixing seats are separately welded to four corners of the outer wall of the bottom of the sale cabinet body, a fixing hole is formed in the bottom of each fixing seat, a buffer plate adheres to the inner wall of the bottom of the sale cabinet body, and a fixing plate which is placed vertically is welded to the inner wall of the bottom of the sale cabinet body. By the sale cabinet convenient to observe for sale of the computer software discs, people can conveniently know functions of the discs, observation is facilitated, the inside of the sale cabinet body can be sterilized, bacteria can be prevented from polluting disc bodies, when the disc bodies are taken, a transmission plate is driven to rotate, thus, spiral wires are driven to rotate, the disc bodies are driven to move out, impact force can be buffered when the disc bodies drop, the disc bodies are protected against being damaged, and the safety of the device is improved.
