when the two clamping plates 8 are clamped on two sides of the computer display, along with the increase of clamping force, the pressing plate 13 is gradually extruded outwards, the pressing plate 13 is extruded outwards through the pressing rod 17 to enable the air plug 18 to move in the movable groove 19, at the moment, the first spring 20 is compressed, the air plug 18 moves in the movable groove 19 to extrude air in the movable groove 19, so that the air is filled in the column groove 14 through the communicating pipe 21, the movable plug 16 and the flexible clamping column 15 can be pushed outwards by the air filled in the column groove 14, and the flexible clamping column 15 extending out of the column groove 14 can be flexibly clamped on the front side and the rear side of the computer display, and therefore the clamping and fixing effects can be further improved;
after the positioning cabinet 1 is clamped and fixed on the back of the computer display, the position of the positioning bracket is adjusted through the flexible rod 10, so that the positioning bracket is positioned beside the computer display, and when digital products need to be loaded, the digital products are directly placed on the supporting plate 23 of the positioning bracket;
when the digital product is placed on the supporting plate 23 of the positioning bracket, under the action of gravity of the digital product, the supporting plate 23 is pressed to move downwards, the supporting plate 23 is pressed downwards to drive the double-sided rack 26 to move downwards, on one hand, the lifting plate 27 is used for compressing the second spring 29, on the other hand, the side wheel 30 meshed with the outer wall of the double-sided rack 26 is driven to rotate, the eccentric wheel 24 is driven by the side wheel 30 to rotate through the linkage shaft 32, the side face of the eccentric wheel 24 is propped against two sides of the digital product, so that the digital product can be automatically clamped and fixed, the anti-falling plate 25 on the eccentric wheel 24 plays an anti-falling role, and the digital product can be blocked between the anti-falling plate 25 and the backboard 22, so that the digital product is effectively prevented from falling;
when the double-sided rack 26 moves downwards, the driving wheel 33 meshed with the outer wall of the double-sided rack is driven to rotate, the driving wheel 33 rotates to gradually enable the driven rack 34 meshed with the other side of the outer wall of the double-sided rack to rise, and the driven rack 34 rises to drive the top plate 36 to rise, so that when a digital product is loaded, the top plate 36 automatically rises and supplements light by using the light supplementing lamp 37 on the top plate 36, when the double-sided rack is used at night, the periphery of the digital product is also provided with a certain brightness, the eyesight is effectively protected, and when the digital product is not loaded, the top plate 36 is tightly attached to the top of the back plate 22, the whole volume is smaller, and the double-sided rack is easy to store and carry;
a heat radiation fan is arranged in the heat radiation barrel 40, the heat radiation fan is used for air inlet from the filter screen 41, air outlet from the heat radiation hole 42, and the discharged air is blown on the back surface of the digital product and then flows out from a gap between the digital product and the backboard 22, so that the heat radiation of the digital product can be effectively realized;
when the digital product is not loaded, the top plate 36 is tightly attached to the top of the back plate 22, and then the cover plate 39 also covers the filter screen 41 to prevent external impurities from entering the heat dissipation cylinder 40;
when loading the digital product, the top plate 36 is gradually far away from the back plate 22, and then the cover plate 39 is gradually removed from the filter screen 41, so that the filter screen 41 can be opened for air intake;
in the back and forth movement of the cover 39 relative to the filter 41, the cover 39 can clean the meshes of the filter 41 by the bristles arranged on the outer wall of the cover, thereby effectively preventing dust from blocking the meshes of the filter 41.
