The working principle of the invention is as follows:

when the suction type electronic component self-checking device is used, the suction type electronic component 2 needs to be inserted into the installation shell 1, each pin of the suction type electronic component 2 is inserted into the slot, the size of the electronic component is consistent with that of the cavity inside the installation shell 1, when the electronic component is inserted into the installation shell 1 to reach the lowest part, the shell at the bottom of the electronic component presses down the adsorption ball 11, the upper friction block 12 is arranged above the bottom wall inside the installation shell 1, the upper friction block 12 is pressed downwards when the electronic component is installed, so that the electronic component and the lower friction block 13 collide and rub, oxygen inside the fixed suction disc 9 and inside the adsorption channel 10 is consumed in the process of collision and rubbing of the two friction blocks, a pressure difference is formed between the inside and the outside of the fixed suction disc 9, the fixed suction disc 9 can fixedly adsorb the outer wall of the main electronic component, and the looseness of the main electronic component can be prevented in the later working process, moreover, because the adsorption ball 11 is made of elastic material, after the electronic element is taken out, the adsorption ball 11 can be bounced again, so that the upper friction block 12 is separated from the lower friction block 13, and the next installation and use are facilitated;

when the self-checking device does not work, the one-way valve bucket 33 can be supported and attached to the bottom wall of the upper air supplementing channel 18 under the action of the elastic force of the supporting spring 34, so that the gas in the lower air supplementing channel 32 cannot flow back to the upper part, after the electronic component is installed in the installation shell 1, the air pressure in the fixed sucker 9 and the adsorption channel 10 is reduced, the one-way valve bucket 33 is pressed towards the lower air supplementing channel 32 by the atmospheric pressure due to the fact that the pressure in the upper air supplementing channel 18 above the one-way valve bucket is larger than the pressure in the lower air supplementing channel 32 below the one-way valve bucket, and is tightly matched with the one-way valve bucket, and the situation that the adsorption effect is reduced due to the fact that air leakage points do not occur in;

when the attraction type electronic component 2 is installed inside the installation shell 1, and the weak current detection insertion sheet 7 is communicated with a power supply, the detection controller 29 can control the circuit to start self-checking, the weak current detection sheet 7 can supply power to the electromagnetic coil 22, so that the electromagnetic coil 22 is electrified, then the electromagnetic coil can adsorb the lever 24 to move downwards, the connector 25 on the right side of the lever 24 can be coincided and communicated with the connection point 26, the detection controller 29 can receive a communication signal at the moment, the process lasts for three seconds, and the steps can be repeated for five times after five seconds, so that whether the circuit component inside the attraction type electronic component 2 can meet the requirements in use can be detected;
