Place the instrument to be tested on the upper surface of the support platform, then pull the mounting plate outward, so that the strip plate can drive the through shaft to move, and the piston rod can move downward. Through the support platform and the piston tube, the piston shaft can carry the limit block close to the instrument, and then the instrument can be fixed.

When the seesaw contacts the toggle block, the driven shaft continues to move up, which will cause the seesaw to squeeze the toggle block, thereby causing the vibration rod with the toggle block to move toward the connecting shaft and compress the spring three. Then the driven shaft continues to move upward, which will cause the seesaw to rotate, thereby causing the seesaw to pass over the toggle block. At this time, the toggle block will be instantly reset under the elastic force of the spring three, thereby causing the vibration rod to knock on the side of the instrument. Through the rotation of the connecting plate and the spring one, the vibration rod can knock on multiple positions on the side of the instrument, thereby more comprehensively testing the anti-vibration performance of the instrument. 3.

By changing the position of the hemisphere, more data can be provided to ensure the accuracy of the test results. BRIEF DESCRIPTION OF THE DRAWINGS
