The invention discloses a forming die with an adjustable die cavity and belongs to the field of dies. The forming die with the adjustable die cavity comprises a support. The upper end of the support is fixedly connected with a die box, and a perpendicular movable plate is arranged in the die box. Two pairs of air cylinders are fixedly connected to the support, and the stretching and contracting ends of the air cylinders penetrate the bottom end of the die box and are fixedly connected with the perpendicular movable plate. A horizontal movable plate is arranged at the upper end of the perpendicular movable plate, and an electric push rod matched with the horizontal movable plate is fixedly connected to the side wall of the perpendicular movable plate. An auxiliary support is fixedly connected to the side wall of the die box, a sealing cover matched with the die box is connected to the upper end of the auxiliary support in a sliding manner, and three limiting pillars matched with the sealing cover are fixedly connected to the upper end of the die box. A positioning rod is connected between one limiting pillar and the auxiliary support. The size of the containing cavity of the die canbe conveniently adjusted, and the production requirements of different sizes of concrete blocks are easy to meet.

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 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 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. The invention further discloses a testing method adopting the device. The device can simulate coal stress, gas pressure, shield coal pillar influences and gas seepage influences, and therefore the simulation degree of a test is increased. The repeat function of conducting multiple outburst experiments by loading a coal sample once is realized, and working efficiency is improved.
