The utility model belongs to the technical field of greenhouse, disclose a kind of precision control ventilation opening automatic switch's greenhouse, including the greenhouse body, the cotton quilt being laid on the greenhouse body and the roller blind mechanism for controlling the winding and unwinding of cotton quilt, and the roller blind mechanism includes the roller blind rod for winding cotton quilt, and the length direction of greenhouse body is equipped with ventilation opening;At least one first positioner for identifying the position of roller blind rod is fixed on the greenhouse body, and the first positioner is located below 0~2 meters of ventilation opening, and the signal output end of first positioner is connected with the signal input end of roller blind mechanism.The utility model can accurately open or close ventilation opening, with high degree of automation, long service life, and is suitable for greenhouse automatic winding and unwinding cotton quilt.

This invention belongs to the field of display device technology, specifically a display module disassembly and assembly tool and its usage method. The tool includes first and second structural components; the first structural component has a handheld part, an mounting part, and a contact part connected in sequence, with two longitudinally extending mounting grooves symmetrically arranged within the mounting part; the second structural component has a pressing ring, sliding arms located at two free ends of the pressing ring, and claws connected in sequence. The sliding arms slidably pass through the corresponding mounting grooves, and an elastic reset element is provided between the sliding arms and the wall of the mounting groove. The two sliding arms are extended outwards towards the contact part. The part of the pressing ring opposite to the handheld part is the pressing part; external force causes the pressing part to move relative to the handheld part, driving the sliding arms to slide and compress the elastic reset element, opening the two claws; when the external force is removed, the elastic reset element pushes the sliding arms back to their original position, and the two claws retract. This tool allows for single-handed control of the claw opening and closing, opening upon gripping and clamping upon release, conforming to ergonomics, greatly simplifying the steps, and improving disassembly efficiency.

This utility model belongs to the field of valve device technology and discloses a machine tool liquid tank replenishment control valve, including a valve body and a liquid outlet pipe opened at the bottom of the valve body. A first liquid inlet pipe and a second liquid inlet pipe are respectively opened on both sides of the valve body. The first liquid inlet pipe and the second liquid inlet pipe are connected. The liquid outlet pipe is perpendicularly arranged to the connection of the first liquid inlet pipe and the second liquid inlet pipe and is connected to each other, so that the pipeline of the first liquid inlet pipe, the second liquid inlet pipe and the liquid outlet pipe are arranged in a T-shape. This utility model integrates the valve body in a T-shape and has two independently controllable semi-circular valve stems built in. It can control the liquid inlet of two liquid inlet pipes simultaneously in a single valve body. Compared with the traditional solution of two independently placed valve structures, the space occupied is greatly reduced, the overall structure is greatly simplified, and the installation and arrangement of the valve is more convenient.
