The utility model discloses a disinfection cleaner for laparoscopic minimally invasive surgery suture, and belongs to the technical field of medical instruments. The disinfection cleaner for laparoscopic minimally invasive surgery suture comprises a main body, the main body comprises a cleaning box, a draining mechanism is arranged in the cleaning box, the draining mechanism comprises a pair of L-shaped connecting frames, a connecting ring is connected between the bottom ends of the pair of L-shaped connecting frames, the interior of the connecting ring is connected with a cleaning barrel through a bearing, the upper end of the cleaning barrel is connected with a hollow ring, and the lower end of the hollow ring is connected with the cleaning barrel. The upper end of one L-shaped connecting frame is connected with a U-shaped frame, a waterproof motor is installed at the upper end of the U-shaped frame, the output end of the waterproof motor penetrates through the U-shaped frame, extends into the U-shaped frame and is in transmission connection with a gear, and the gear is meshed with the outer gear ring. And the practical value is high.

This utility model belongs to the field of seedling technology, and in particular to a seedling tray, comprising: a base, including a frame-shaped main body, on which symmetrically arranged side sealing plates are provided; and a top tray, including a top frame, on which multiple through-holes are provided, and a main sealing plate forming a U-shape is provided at the bottom of each through-hole. The bottom of the main sealing plate is provided with a drainage hole. The main sealing plate and the side sealing plates cooperate to form multiple seedling pits. The entire top tray can be removed. The sides of the main sealing plate forming the U-shape are not blocked by the side sealing plates, so the sides are open, which allows for convenient removal of the nutrient soil and seedlings together. It eliminates the need to remove the nutrient soil and seedlings from the seedling pits one by one with a small shovel, making it more convenient. The removed nutrient soil is also more intact, preserving more roots and improving the survival rate of the seedlings.

This utility model provides a drilling rig reaming mechanism and drilling machinery. The drilling rig reaming mechanism includes a reaming device, which comprises a hollow base, a drive device disposed within the base, a hinge assembly, and a cutter head assembly. The cutter head assembly includes a cutter head mounting seat and a cutter head, with the cutter head fixedly mounted on the cutter head mounting seat, which is hinged to the base. The first end of the drive device is connected to the base, and the second end of the drive device is connected to the hinge assembly, which is hinged to the cutter head mounting seat. During its extension and retraction movement, the drive device can drive the cutter head assembly to rotate outward or inward to retract via the hinge assembly. This drilling rig reaming mechanism, by driving the cutter head assembly to rotate outward or inward to retract via the drive device, reduces the risk of cutter head damage while ensuring reaming efficiency and minimizing the occurrence of stuck drill accidents.
