[0039] The detailed connection means is a well-known technology in the art, and the working principle and process are mainly introduced below. The specific work is as follows.

[0040] Firstly, the device is placed stably 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 near the right end of the bearing seat 18 and needs to be located on the left side of the impact plate 19, then according to the length or width of the test product, the other fixed assembly 2 is adjusted to move, and the test 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;

[0041] If it is to test a circuit board within a certain thickness range, 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 test product to perform flexible force, and the lower pressing bolt 23 is effectively rotated to press and fix;

[0042] Then according to the test 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, and the first rotating rod 34 at the rear side of the second gear 38 is turned 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 is turned over, the force frame 39 is driven to displace, and the force frame 39 is turned over by the limiting of the second rotating rod 35;

[0043] The force frame 39 can be turned over to be horizontally located or relatively vertically located below the bearing seat 18 by the turning over of the first rotating rod 34 and the turning over and limiting of the second rotating rod 35;

[0044] The position of the turnover table 40 after turning over is adjusted by driving the electric slide rail 31 to move the turnover frame 33 through the adapter arm 32, so that the turnover table 40 is relatively connected or has a certain distance on the right side of the bearing seat 18, or the position of the turnover table 40 vertically located below the bearing seat 18 is adjusted, so that the turnover and displacement adjustment of the impact structure 5 are realized;

[0045] The second motor 56 is controlled to start, the driving rod 55 is driven to rotate, the top rod 58 is driven to rotate by the arc-shaped force storage groove 7 on the driving rod 55, the force receiving seat 57 is driven to slide on the slide rod 52 and compress the second spring 54, the force storage of the second spring 54 is realized, 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 slide rod 52 and the spring is compressed to realize auxiliary force storage by rotating the force adjusting nut 53;

[0046] When the top rod 58 enters the reset groove 6 from the force storage groove 7 with the rotation of the driving rod 55, the force receiving seat 57 is reset and shot out by the second spring 54, that is, the force receiving plate 60 on the connecting rod 59 is shot out; the impact plate 19 is impacted and tested by the force receiving plate 60, or the lower wall of the hanging table 13 is impacted and tested by the force receiving plate 60;

[0047] When the force receiving plate 60 impacts the lower wall of the hanging table 13, the test is a rigid impact test, and the impact direction is a vertical force;

[0048] When the force receiving plate 60 impacts 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 rigid test or flexible test of horizontal force;

[0049] 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 on the impact plate 19 will drive the bearing seat 18 to the left, and the sliding seat 16 will move to the left in the sliding groove 8, and the adjusting screw 15 will pass through the sliding groove 8, when the sliding seat 16 contacts the first spring 14, it will be buffered to realize flexible impact test, if the first spring 14 is forced to reverse, the sliding seat 16 will be pushed to the right, then the bidirectional impact test is realized;

[0050] 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 at a certain height, the sliding seat 16 is limited by the adjusting nut 17 and cannot move, at this time the force on the impact plate 19 realizes the horizontal force of rigid impact test, and the rotation of the driving rod 55 driven by the second motor 56 can continuously reciprocate and quickly impact.

[0051] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
