The invention discloses a combined table and stool, which relates to the technical field of portable furniture, and comprises a folding stool and a table plate. The table plate comprises a first halfplate and a second half plate, and the sides, close to each other, of the first half plate and the second half plate are hinged; a clamping groove is formed in the joint of the first half plate and the second half plate on the side, deviating from the table top, of the table plate, and the upper side of the folding stool in the extending state is matched with the clamping groove in an embedded mode; a containing groove used for containing the folding stool is formed in the side, away from the table top, of the first half plate, and a locking piece used for locking the folding state of the first half plate and the second half plate is arranged between the first half plate and the second half plate. The combined table and stool has the advantages that the table plate and the stool can be conveniently used independently, the convenience of using the combined table and stool is improved, the structure leakage is reduced, the situation that the combined table and stool is accidentally damaged to affect normal use is reduced, and the combined table and stool are convenient to carry manually.

The invention discloses a flat plate type notebook computer flipping device. The flat plate type notebook computer flipping device comprises a main body bottom cover, a double-shaft core rotating shaft, a snapping plate mounting head and an upper connecting shaft core. A main body part is mounted above the main body bottom cover, a keyboard is mounted above the main body part, and a flat face-piece sleeve is mounted above a face-piece cover. A connecting clamping plate is mounted on the side of the double-shaft core shaft, and a clamping plate mounting head is installed under the connecting clamping plate, a clamping plate support plate is installed below the clamping plate mounting head, and the clamping plate support plate is mounted on one side of the clamping plate mounting head, a rotary shaft body is mounted on one side of the clamping plate support plate, and a lower connecting shaft core and an upper connecting shaft core are installed inside the rotary shaft body. The flat plate type notebook computer flipping device has the beneficial effects that a tablet computer can be changed into a notebook computer when the keyboard is used for typing, and the tablet computer can beused alone when opening the keyboard by 360 degrees to play a protective role, and an open-to-reverse angle can support an A-shape and the experience is more intuitive.

The invention discloses a pencil bag used by an interior decoration person. The pencil bag used by the interior decoration person comprises a pencil case outer shell, a rotating block is rotated to drive a rotating sleeve to rotate synchronously, and the rotating sleeve drives a threaded seat to move upward by screw-thread fit to drive pencils to move upward, and the threaded seat is moved to the top end when the pencil needs to be replaced, and then a clamping block can be overturned to release the clamping with the pencil. A screwdriver, the pencil and a measuring function are combined together, and the pencil bag used by the interior decoration person is convenient to use alone. Measured data can be recorded on a display screen, and the situation that recording is carried out once when measurement is carried out once is avoided. Different screwdriver heads are selected according to different screws, the pencil is inside, and a pencil head is not broken.

The invention discloses a multi-chamber fluid packaging bag. The multi-chamber fluid packaging bag comprises a mixed bag and at least two mutually independent soft bag bodies, one side of each soft bag body is provided with a bag opening, one side of the mixed bag is provided with a sealing edge which makes the bag openings communicated with the mixed bag by extruding the soft bag body, and the other side of the mixed bag is provided with a sealing edge used for opening or sealing the mixed bag. By connecting multiple soft bag bodies with individual sealed spaces and a mixed bag to the packaging bag, multiple spices with different flavors can be contained and extruded into the mixed bag to be completely mixed, inconvenience brought by using third party equipment is avoided, the situation that due to the fact that two spices are contained in the same packaging bag, the ingredients lose effectiveness is avoided, by extruding the soft bag bodies, spices in all bag chambers can be extruded into the mixed packaging bags to be mixed and then extruded out, the situation that when the spices are used, the spices make contact with hands or clothes or other objects is prevented, hygiene and convenience are achieved, and waste is avoided.

The invention discloses a quick releasing device for a gas dynamic disaster simulator stand. The device comprises an outburst cylinder, wherein a plurality of piston barrels are connected to the outburst cylinder, and the total length of the piston barrels is identical with the thickness of a shield coal pillar; the piston barrel at the tail end is connected with a loading pressure relief barrel through a flange structure, and the end, connected with the piston barrel, of the loading pressure relief barrel is connected with an outburst barrel; a piston head is arranged in the loading pressure relief barrel in a sliding and sealing mode, the piston head is connected with a piston rod, and the piston rod stretches out of the free end of the loading pressure relief barrel and is connected with an external power device; a transparent observation window is arranged on the piston barrel connected with the loading pressure relief barrel; each piston barrel is connected with a seepage air outlet pipe.
