7. A method of using a DNA identification sample collector, comprising:
in an initial state, the pushing spring, the connecting spring and the lifting spring are all in a compressed state, and the contact switch is positioned in the lifting cavity;
the first step is as follows: the test tube with the blood sample penetrates through the clamping hole and then is inserted into the semicircular groove, the clamping block is enabled to simply limit the shaking of the test tube under the elastic force action of the clamping spring, the spring rod is enabled to be pressed downwards due to the test tube with the blood sample, the chain is loosened while the supporting spring is compressed, the connecting spring is enabled to reset and drive the lower pressing rod to descend, the rear end of the rotating rod is enabled to descend, the front end of the rotating rod is enabled to ascend, the rotating column is enabled to move upwards, the lifting spring is enabled to reset and drive the lifting plate to ascend, and therefore the upper end of the contact switch enters the lifting cavity;
the second step is that: after the test tube is installed, the cover plate is manually rotated, so that the storage cavity is sealed, the lifting rod is lowered, the lifting plate is lowered and is in contact with the contact switch, the driving motor is started to work, the driving motor is lowered due to the lowering of the lifting plate, the driving shaft and the cam are lowered, the cam is pressed against the movable block to move the movable block, so that the test tube is inclined, the driving shaft is driven to rotate due to the work of the driving motor, the cam is driven to rotate, the movable block is shaken front to back left and right under the action of the compression spring, so that the test tube is shaken, when the test tube is empty, the support spring is not compressed, so that the lower pressing rod is positioned at the top, the connecting spring is still in a compressed state, the rear end of the rotating rod moves upwards and the front end moves downwards, so that the lower end of the rotating column presses down the lifting, the lifting spring is compressed, so that the contact switch is still positioned in the lifting cavity, the lifting plate is still not contacted with the contact switch when the lifting plate descends, and the driving motor cannot work;
the third step: after the cover plate is rotated, the trapezoidal block returns to the ejection cavity firstly and compresses the ejection spring, when the ejection cavity is communicated with the pressing hole, the ejection spring is reset to drive the trapezoidal block to move, so that the pressing block moves towards the direction far away from the storage cavity, the pressing spring is stretched, when the box needs to be opened, the pressing plate is only manually pressed, the pressing block presses the trapezoidal block to enable the trapezoidal block to return to the ejection cavity, and then the cover plate is rotated, so that the cover plate can be rotated;
the fourth step: when the safe deposit box takes place to empty or incline left, the sliding block of the left and right sides moves left, left sliding spring relaxs left rope simultaneously in the left sliding block removal compression, the sliding spring on the tensile right side of sliding block left motion and the rope on taut right side, left rope relaxs and makes left promotion piece be close to towards the test tube under the effect of left promotion spring, thereby make the carriage release lever move right, thereby make the left clamp plate of test tube move right and draw the left extension spring of test tube, thereby make the left clamp plate of test tube support the test tube, thereby avoid the big angle slope of test tube and cause the test tube to break into pieces the condition, thereby play the effect of protection test tube.
