The second fastener 433 is detachably connected to the lifting plate 42 and presses against the baffle 431. The baffle 431 blocks the opening of the slide groove 421, preventing the mounting plate 32 from coming out of the opening of the slide groove 421. The first fastener 432 and the second fastener 433 ensure a secure connection between the baffle 431 and the lifting plate 42, preventing the baffle 431 from falling off.

[0091] For example, the first fastener 432 and the second fastener 433 are threaded fasteners such as screws or bolts. Preferably, one end of the first fastener 432 and the second fastener 433 has a screw handle.

A guide sleeve 1141 is provided on the mounting frame 114, and a guide rod 422 is provided on the lifting plate 42. The guide rod 422 is slidably inserted into the guide sleeve 1141. When the lifting drive mechanism 41 drives the fixture module 3 to move up and down, the guide rod 422 slides within the guide sleeve 1141, guiding the lifting movement of the fixture module 3, improving the accuracy of the lifting movement, and preventing misalignment.

[0093] like Figure 2 and Figure 6 As shown, the automated testing device also includes an obstruction detection module 6, which is connected to the housing 1. The obstruction detection module 6 is used to detect whether there is an obstruction between the carrier module 2 and the fixture module 3, so as to ensure the safety of the pressing module 4 driving the fixture module 3 to move down.

[0094] For example, the occlusion detection module 6 is a grating.

The operation panel 5 is used to control the operation status of the testing device, such as running, stopping, and emergency stopping, to realize human-machine interaction.

[0096] Specifically, the operation panel 5 has two start operation buttons 51 spaced apart and connected in series. The start operation buttons 51 are used to issue a command to start testing the module under test. To begin testing, both start operation buttons 51 must be pressed simultaneously to ensure safety and prevent accidental start of the test device. The two start operation buttons 51 are located on opposite sides of the operation panel 5, requiring the operator to use both hands and press both buttons simultaneously to begin testing.

[0097] For example, the start operation button 51 is in the form of a button, but in other embodiments it can also be in the form of a knob. Figure 11 Below the start button 51 is a "Start" label, indicating that it is the start button.

[0098] Furthermore, the operation panel 5 also includes a reset button 52, an emergency stop button 53, and indicator lights.
