The invention discloses an aluminum support twisting device. The device comprises a base, wherein a left vertical plate is fixedly welded to the top of the base in the direction close to the left side, a right vertical plate is fixedly welded to the top of the base in the direction close to the right side, and a sliding rail groove is formed in the top of the base and located between the left vertical plate and the right vertical plate. The aluminum support twisting device is advantaged in that aluminum bracket plates are arranged in a twisting groove and a placing groove, after the position is adjusted, fixing bolts are screwed in threaded holes, movement of the aluminum bracket plates is limited by the fastening force of fixing bolts and fastening springs on the aluminum bracket plates,once twisted, the fixing bolts are screwed off, the fastening springs are pressed down, finished products are disassembled, and the convenient mounting and dismounting effect is achieved, when the aluminum bracket plates of different specifications need to be twisted, a movable base is moved to the designated position, a hand wheel is made to rotate to drive a clamping groove to clamp the aluminumsupport plates, a twisting motor is started to twist the aluminum support plates, and thereby the effect that the twisting device is adjustable is achieved.

The embodiment of the invention provides a 3D display device and display method and a 3D display system. The 3D display device and display method and 3D display system achieve the situation that a viewer can always achieve an optimal viewing effect when moves back and forth in a large range. The 3D display device comprises a display panel, a phase delay unit, a sensing unit and an adjustment unit.The phase delay unit is located on a display side of the display panel and comprises a plurality of light polarization units, and the polarization direction of light emitted by every adjacent two light polarization units is perpendicular. The sensing unit is used for acquiring the viewing distance when the viewer views in real time. The adjustment unit is electrically connected with the sensing unit and the phase delay unit and is used for determining the width of the light polarization units corresponding to the viewing distance fed back in real time according to the viewing distance fed back by the sensing unit in real time and adjusting the width of the light polarization units to the determined width corresponding to the viewing distance fed back in real time.

The invention relates to an adjustable graphite cream spraying system for a friction press machine in order to solve the problem that an existing graphite cream spraying system cannot be adjusted. Theadjustable graphite cream spraying system for the friction press machine comprises a base, a forming mold and a spraying device. The forming mold and the spraying device are both arranged on the base. The spraying device comprises a cover plate and a box. An upper plate of the cover plate is provided with a through hole. A front side plate of the cover plate is provided with a mounting hole and fixing screw holes. The cover plate and the box are fixed through fixing screws in a threaded mode. The fixing screws and the fixing screw holes are arranged in a threaded mode. A power mechanism is arranged in the box. According to the adjustable graphite cream spraying system for the friction press machine, a combined structure composed of a threaded rod, a threaded pipe, a first gear, second gear, a rotary shaft and a motor is additionally arranged; the power mechanism is arranged at the upper end of the threaded rod, and a spray pipe is arranged on the power mechanism; by changing the rotating direction of a forward and reverse rotating motor, the power mechanism can ascend and descend through the threaded rod and the threaded pipe, and then the adjustable effect of the spraying systemis achieved.

The invention discloses a seeding machine with adjustable interval, which includes a box body. A material inlet hopper is communicated with the left side of the top of the box body. The bottom of the material inlet hopper penetrates through the box body, is stretched into the interior of the box body and is communicated with a fixed box. A separation board is movably connected to the interior of the fixed box. A first through hole is formed in the right side of the fixed box. The right side of the separation board penetrates through the first through hole, is stretched into the exterior of the first through hole and is fixedly connected to an electric telescoping rod. By means of cooperation of a moving pipe, a second through hole, a fixed block, a slide trough, a slide rod, a toothed plate, a fixed plate, a gear, a third through hole, a fourth through hole, a rotary disk, a rotary shaft and a worm, which are matched together, seeding interval can be adjusted. The seeding machine solves problems that the seeding interval of a seeding machine in the prior art is fixed and cannot be adjusted according to growth environment of crops. The seeding machine increases yield of crops and increases economic incoming of farmers.

The invention discloses a project acceptance device used for a brick-concrete structure building and relates to the technical field of project acceptance devices. The device comprises a shell. The bottom of the shell is movably connected with adjustable supports which are uniformly distributed. The tops of the adjustable supports are engaged with adjusting gears correspondingly. The middles of theadjusting gears are fixedly connected with calibration nuts which are rotationally connected with the inner wall of the shell. The bottom of the shell is fixedly connected with a charging port. According to the project acceptance device used for the brick-concrete structure building, through cooperative using of torsional springs and a turnplate, in an initial state, a labelled hose is wound on the turnplate in a disc shape, in addition, the turnplate rotates when the labelled hose is pulled out, meanwhile, the torsional springs are driven by the turnplate to rotate, and meanwhile, the torsional springs are driven by the turnplate to rotate; and when the labelled hose becomes back in a flexible state after being used, the labelled hose is wound back into the shell under the effect of thetorsional springs and wound on the turnplate, accordingly, the effect of convenient carrying is achieved, using and recovering are facilitated, the occupation area is small, and using is more convenient.

The invention discloses an adjustable fixing device used for maintenance of motor shells and capable of achieving centering, and relates to the technical field of civil cleaning equipment. The fixing device comprises a mounting seat, the middle part of the mounting seat is rotatably connected with a rotary table, the middle part of the rotary table is provided with uniformly distributed limiting grooves, the middle parts of the limiting grooves are movably connected with limiting columns, and the back surfaces of the limiting columns are fixedly connected with movable blocks. According to the adjustable fixing device used for maintenance of the motor shells and capable of achieving centering, through cooperative use of the rotary table and the limiting columns, in an initial state, telescopic blocks are in a stretching-out state under the action of first springs, the movable blocks are located at the innermost side of the mounting seat, and when the shells are fixed, the shells are placed in the middle of the mounting seat firstly, then the rotary table is rotated, the movable blocks move towards the inner side of the mounting seat through the limiting grooves and the limiting columns, adjustment is performed according to the shells of different sizes, and the shells are clamped and fixed by clamping plates, so that the adjustable effect is achieved, the clamping range is increased, the cleaning cost is saved, and the cleaning efficiency is improved.
