(III) advantageous effects

Compared with the prior art, the invention provides an integrated material evidence accepting table, which has the following beneficial effects:

1. this platform is accepted to integration material evidence owing to set up square groove cooperation fixture block and can support the connecting plate, improves the holding power that the connecting plate received, avoids the connecting plate to drop, improves the practicality of this device.

2. This platform is accepted to integration material evidence utilizes two opposite sex magnet cooperation square grooves and fixture block, makes things convenient for people to look for the cylinder like this and leads to the position of groove one, from can be quick convenience with fixed plate and connecting plate together fixed, and the adsorption affinity of two special-shaped magnets improves the fixed effect of connecting plate, avoids the connecting plate to drop, improves the practicality of device.

3. This platform is accepted to integration material evidence utilizes the separation piece cooperation cardboard can be fine carry out the card to the cylinder with, avoids the cylinder random to remove, and then has guaranteed the fixed effect of connecting plate, makes the connecting plate can not drop easily like this, improves the practicality of device.

4. This platform is accepted to integration material evidence owing to utilize the fixed cylinder of separation piece cooperation cardboard, like this when people exert force, can be very convenient extract the cylinder to take off the connecting plate, make things convenient for people to look over and place the paper of filling up the material evidence.

5. This platform is accepted to integration material evidence, because the air current need get into the gas-supply pipe through the hose, the inside of hose can be full of gas like this to the holding power that utilizes the hose to be full of after gaseous can make the hose exert the power that moves to the base plate to the fly leaf, thereby the fly leaf has begun to move to the middle part when making gas inflow gas-supply pipe, then utilizes the air current to blow the power that produces when to the kicking block, makes two fly leaves remove to the middle part, cliies the front end of paper, avoids the paper crooked.

6. This platform is accepted to integration material evidence, when taking out the connecting plate, the cardboard can utilize the thrust of aerofoil to remove left, thereby it is sealed to lead to groove two, it is like this that the air can only be a small amount or not have the air admission gas-supply pipe, it does not have sufficient air current to support to make the hose like this, thereby let the hose shrink, it drives the fly leaf and opens to both sides to utilize the hose shrink, and because the inside air current of gas-supply pipe is few, can't make the kicking block produce the power of closed fly leaf, like this when people take the paper on the connecting plate, the fly leaf opens, make things convenient for people follow-up to fix the connecting plate on the fixed plate, improve the convenience when using, make things convenient for people to use.

7. This platform is accepted to integration material evidence because set up dry gas output mechanism, makes the inside air that gets into the file case keep dry like this, has avoided the paper to wet, has improved the save time of paper.

8. According to the integrated material evidence reception table, the air holes are arranged in a circular truncated cone shape and matched with a cylindrical shape, and the blocking plates are arranged in a conical shape, so that when the connecting plates are fixed on the fixing plate, the air holes can be better sealed, air can enter each air conveying pipe, and the floating blocks can generate enough force; and when the internal air pressure is larger, the air can generate larger force on the blocking plate, so that the redundant air can be normally discharged when the air pressure is larger, the load of the air blower is reduced, and the service life of the air blower is prolonged.

9. This platform is accepted to integration material evidence has set up the gasket and can make and produce the gap between half slot and the cylinder, and assurance cardboard of bigger degree can not reciprocate with hole one or three contacts in hole like this, assurance cylinder can be normal.

10.
