[0031] The detailed connection means is the technology known in the art, and the working principle and process are mainly introduced below. The specific work is as follows.

[0032] Firstly, the device is stably placed through the base 11; during testing, one of the fixed assemblies 2 is installed at the left end of the bearing seat 18, and the other fixed assembly 2 is installed at the position close to the right end of the bearing seat 18 and needs to be located at the left side of the impact plate 19, then according to the length or width of the tested product, the other fixed assembly 2 is adjusted to move, and the tested product is placed on the bearing seat 18 and clamped by the blocking seat 21, and the blocking seat 21 is fixed and limited by the fixed bolt 22 after moving; If it is a certain thickness range such as a circuit board, the two ends of the circuit board can be located below the other end of the blocking seat 21, then the lower pressing bolt 23 is rotated, the sleeve cap 24 with rubber pad is contacted with the tested product to perform flexible force, and the lower pressing bolt 23 is effectively rotated to press and fix; Then, according to the testing requirements, the force direction of the impact structure 5 is adjusted through the transposition structure 3; that is, the first motor 36 on the turnover frame 33 is driven to rotate the first gear 37, the first gear 37 is engaged with the second gear 38, the first gear 37 drives the first rotating rod 34 on the rear side of the second gear 38 to turn over; since the force frame 39 is movably arranged between the other end of the first rotating rod 34 and the other end of the second rotating rod 35, and the shape and length of the first rotating rod 34 and the second rotating rod 35 are different, when the first rotating rod 34 turns over, the force frame 39 is displaced, and the force frame 39 is limited by the second rotating rod 35 to realize the turnover of the force frame 39; The force frame 39 can be turned over to the horizontal or relatively vertical position below the bearing seat 18 by the turnover of the first rotating rod 34 and the turnover and limitation of the second rotating rod 35; The position of the turnover table 40 after turnover is adjusted by driving the electric sliding rail 31 to move the turnover frame 33 through the adapter arm 32, so that the turnover table 40 is relatively interfaced or has a certain distance on the right side of the bearing seat 18, or the position of the turnover table 40 vertically below the bearing seat 18 is adjusted, so as to realize the turnover and displacement adjustment of the impact structure 5; By controlling the starting of the second motor 56, the driving rod 55 is driven to rotate, and by means of the arc-shaped force storage groove 7 on the driving rod 55, the top rod 58 is actuated to rotate, and then the force receiving seat 57 is driven to slide on the sliding rod 52 and compress the second spring 54, so as to realize the force storage of the second spring 54, and the force storage size of the second spring 54 is related to the compression degree of the second spring 54, but since the length of the force storage groove 7 is certain, the force adjusting nut 53 can be moved on the sliding rod 52 and the spring is compressed by rotating the force adjusting nut 53, so as to realize auxiliary force storage. When the top rod 58 enters the return groove 6 from the force storage groove 7 along with the rotation of the driving rod 55, the force receiving seat 57 is reset and shot out by means of the second spring 54, that is, the force receiving plate 60 on the connecting rod 59 is shot out; the force receiving plate 60 impacts and tests the impact plate 19, or the force receiving plate 60 impacts and tests the lower wall of the hanging platform 13; When the force receiving plate 60 impacts and tests the lower wall of the hanging platform 13, the test is a rigid impact test, and the impact direction is a vertical force; When the force receiving plate 60 tests the impact plate 19, it is a horizontal force test; and according to the test requirements, the sliding seat 16 can be adjusted to realize the rigid test or the flexible test of the horizontal force; For example, when the adjusting nut 17 is located at the right end of the adjusting screw 15, farthest from the hanging platform 13, the force of the impact plate 19 will drive the bearing seat 18 to the left, and the sliding seat 16 is limited to move to the left in the sliding groove 8 by means of the sliding seat 16, and the adjusting screw 15 penetrates the sliding groove 8, when the sliding seat 16 contacts the first spring 14, the flexible impact test is realized by buffering, and if the first spring 14 is forced to reverse, the sliding seat 16 is right, and the bidirectional force impact test is realized; When the adjusting nut 17 is rotated on the adjusting screw 15, the adjusting nut 17 is attached to the right side wall of the hanging platform 13 supported by the hanging arm 12 to a certain height, the sliding seat 16 is limited to move by the adjusting nut 17, at this time, the force receiving side of the impact plate 19 realizes the rigid impact test of the horizontal force; and the rotation of the driving rod 55 driven by the second motor 56 can continuously reciprocate and quickly impact.
