Vibration tool and method for improving screening test efficiency of products to be tested

The invention provides a vibration tool and method for improving screening test efficiency of a to-be-tested product. The vibration tool comprises a vibration tool body, the vibration tool body comprises a bottom plate, a first vertical plate and a second vertical plate, and the first vertical plate and the second vertical plate are symmetrically distributed; the lightening holes are formed in the planes of the bottom plate, the two first vertical plates and the two second vertical plates; the first vertical plate and the second vertical plate are arranged in an inclined mode from top to bottom, four rectangular lightening holes are symmetrically distributed in the middle of the bottom plate, each vertical plate is provided with two lightening holes, and the lightening holes are symmetrically distributed in the two sides of the upper ends of the vertical plates. And each to-be-tested product is fixed on the inner side of the vertical plate through eight bolts which are distributed circumferentially. According
