[0030] A specific application of this embodiment is as follows: In use, the operator first places the automotive part to be tested on the workbench 211. Then, the operator rotates knob 214 clockwise, causing the bidirectional threaded rod 218 to rotate. Simultaneously, the rotation of the bidirectional threaded rod 218 causes the moving blocks 219 to move closer together. This movement of the moving blocks 219 also causes the clamping plates 212 to move closer together. The two moving blocks 219 then move together through the clamping plates 212 and slide on the outer surface of the slide rod 217. The slide rod 217 provides support for the horizontal movement of the clamping plates 212. As the clamping plates 212 move closer together, they clamp and fix the automotive part. Simultaneously, the operator can also rotate knob 220 clockwise according to the height of the automotive part, causing the support block 221 to move upwards. The movement of the support block 221 causes the clamping plate 213 to move together and clamp and fix the automotive part, further improving the clamping effect of the equipment. This allows for clamping and fixing automotive parts of different sizes. This significantly improves the practicality of the equipment. After the automotive parts are clamped in place, the operator starts the motor 311, which drives the turntable 313 to rotate. As the turntable 313 rotates, it drives the support rod 315 to reciprocate up and down. The movement of the support rod 315 also drives the limit bracket 316 to move. Thus, the worktable 211 moves along with the limit bracket 316 and completes the vibration test. At the same time, when the worktable 211 moves downward, it drives the second telescopic rod 319 to move inward into the first telescopic rod 318 and compress the spring 317. The spring 317 generates a certain rebound force through the limiting effect of the first telescopic rod 318, which drives the worktable 211 to reset. This greatly improves the vibration effect, the accuracy of the test, and the yield rate of the products. When the motor 311 is working, the motor bracket 312 provides a certain degree of support to ensure its stable operation. The support rod 315 is connected to the off-center of the turntable 313. Therefore, when the turntable 313 rotates, it drives the support rod 315 to reciprocate up and down.
