A groove 22 with a depth of 1 cm is provided around the bottom surface of the inner cavity of the tray 2 body, and anti-slip protrusions 25 are provided on the bottom surface of the inner cavity of the tray 2 body. Specifically, the tray 2 has a rectangular opening cavity structure. The top of tray 2 has an outwardly flared horizontal folded edge A21 around its perimeter. Two sets of through holes 23 are symmetrically arranged on the horizontal surfaces of the two short sides of the folded edge A21. The through holes 23 are the same size as the first locking hole 245 of the built-in spring buckle 24, and are symmetrically arranged vertically to fit the locking post 33 and prevent the pressure ring 3 from moving upward. The bottom surface of the inner cavity of tray 2 has a groove 22 around its perimeter to fit the vertical pressure plate 32 that is locked into the pressure ring 3. At the same time, the bottom surface of the inner cavity of tray 2 has anti-slip protrusions 25 to further reduce the risk of the sterile cloth sliding.
[0034] like Figures 3-5 As shown, in this embodiment, the pressure ring 3 also includes a rectangular ring-shaped folded edge B31. A pressure plate 32 is vertically arranged around the inner side of the bottom surface of the folded edge B31. The pressure plate 32 is adapted to the groove 22 on the bottom surface of the tray 2. The width of the folded edge B31 is equal to that of the folded edge A21. Two sets of locking pins 33 are vertically and symmetrically arranged at the bottom of the two opposite horizontal planes of the folded edge B31. The locking pins 33 are adapted to the through holes 23. Specifically, the folded edge B31 of the pressure ring 3 is a rectangular ring. A vertical pressure plate 32 is vertically arranged on the bottom surface of the folded edge B31. The width of the folded edge B31 is equal to that of the folded edge A21. When the pressure plate 32 is inserted into the groove 22 of the tray 2, the folded edge B31 and the folded edge A21 abut against each other. The first locking hole 245 and the second locking hole 246 coincide. The locking pin 33 is adapted to be inserted into the through hole 23 and extends to the first locking hole 245. The locking pin 33 is fixed by the spring 243 to prevent the pressure ring 3 from moving upward.
[0035] like Figure 6 As shown, in this embodiment, the spring buckle 24 further includes a columnar body 244, a spring 243 is sleeved inside the columnar body 244, a core 242 is provided at the top of the spring 243, and a pressing head 241 is provided at the top of the core 242; a first locking hole 245 is vertically provided on the body of the columnar body 244, and a second locking hole 246 is vertically provided on the body of the core 242, the first locking hole 245 and the second locking hole 246 are of equal size; specifically, the spring buckle 24 includes four parts: the columnar body 244, the spring 243, the core 242 and the pressing head 241. When in use, pressing the pressing head 241 makes the first locking hole 245 and the second locking hole 246 coincide, the locking pin 33 is inserted into the through hole 23 and extends to the first locking hole 245 and the second locking hole 246, and the pressing head 241 is released, and the locking pin 33 is locked and fixed under the action of the spring 243.

At the same time, the silent locking wheels 14 are provided at the bottom of the bracket 1 for easy movement.
[0037] This utility model provides a working principle for a surgical instrument tray: In use, medical staff first take the pressure ring 3, then symmetrically and flatly lay a suitable size of sterile cloth on the tray 2. Then, they use their thumbs and index fingers to lift the two folded edges B31 of the pressure ring 3 with the locking pin 33, aligning the folded edges B31 with the corresponding edges A21 of the tray 2. Then, they press the pressing heads 241 on both sides with their middle fingers, so that the first locking hole 245 and the second locking hole 246 coincide. They press the pressure ring 3 downwards with both hands, so that the locking pin 33 penetrates the sterile cloth and inserts into the first locking hole 245 of the spring buckle 24. They then release their middle fingers. At the same time, the lower part of the pressure plate 32 is inserted into the groove 22 on the bottom surface of the inner cavity of the tray 2, so that the pressure ring 3 is firmly fixed and the sterile cloth is prevented from sliding.
