an operator places the product on the supporting block 3211, adjusts the positions of the first limiting block 3221, the second limiting block 3222 and the third limiting block 3223, so that the product is fixed by the three, and the product is prevented from moving in the test process. Clicking on the start button 332 drives the motor to move the holding device 32 into the cavity 21. The first cylinder 3231 drives the slider 3232 to slide, and the slider 3232 moves the communication terminal 3234 toward the communication unit 311, and inserts the communication terminal 3234 into the communication unit 311. The control system controls the X-axis moving unit 421 and the Y-axis moving unit 422 to move in a predetermined direction, and controls the antenna 433 to emit electromagnetic waves to perform a product test. During the test, if an emergency occurs, the test can be stopped by pressing the emergency stop switch 331. After the test is completed, the driving motor moves the clamping device 32 out of the cavity 21, and the product is taken out to start the test operation of the next round of product.
