[0029] See attached Figure 1 and 2 The chassis 1 includes a housing 1-1, a display 7 tilted on the housing 1-1, a testing platform 1-2 horizontally mounted on the housing 1-1, an air pump 8 fixed to the outside of the housing 1-1 for providing a power source to the drive components, a button 1-3 mounted on the housing 1-1, a control circuit mounted within the housing 1-1, and a connecting plate 1-4 located below the testing platform 1-2 and used to connect the positioning seat 3, the rotary clamping device 4, and the plug-in device. Multiple groups of connecting plates 1-4 and the devices thereon are arranged along the length of the housing 1-1 to facilitate simultaneous testing of multiple USB modules 2.

[0030] An opening is provided on the inspection platform 1-2, with the positioning seat 3 positioned at the opening. The actuating end of the rotary clamping device 4 is located above the opening. The plug-in devices are all located below the inspection platform 1-2, making the overall apparatus aesthetically pleasing and neat. In this embodiment, the rotary clamping device 4 utilizes a rotary clamping cylinder.

[0031] See attached Figure 1-9The above-mentioned plug-in device includes a test line 5 connected to the main port of the USB module 2, a first driving component that drives the test line 5 and the power supply module 21 to move horizontally and electrically connect to the USB interface and the power supply interface at the inner end of the USB module 2, and a second driving component that drives the first adapter line 6 to electrically connect to the USB interface at the outer end of the USB module 2. When the first driving component drives the test line 5 and the power supply module 21 to electrically connect, the power supply module 21 is first electrically connected to the power supply interface at the inner end of the USB module 2, and then the test line 5 is electrically connected to the USB interface. The first driving component acts first, and the second driving component acts later.

[0032] In this embodiment, the USB module 2 has two USB-C ports on its inner end: one for connecting to the industrial computer on the workpiece, and the other for connecting to the DVR port on the recorder. Therefore, these ports also require testing and are equipped with a second adapter cable 20. Therefore, the first driver assembly also drives the second adapter cable 20 to electrically connect to the corresponding ports. The USB module 2 has two USB ports on its outer end: a USB-A port and a USB-C port. Both the first adapter cable 6 and the second adapter cable 20 are connected to a circuit board, which is equipped with a USB flash drive or sampling circuit to test the transmission speed and charging protocol, respectively.

[0033] See attached Figure 3-5 , 6 and 7, the above-mentioned first driving assembly includes a first clamping assembly for fixing the test line 5, a first guide assembly arranged between the first clamping assembly and the connecting plate 1-4 in the chassis 1, and a first driving cylinder 9 for driving the first clamping assembly to move along the guiding direction of the first guide assembly. The first clamping assembly includes a first lower pressing plate 10 connected to the execution end of the first driving cylinder 9, a first upper pressing plate 11 and connecting bolts for connecting the first lower pressing plate 10 and the first upper pressing plate 11. A test line lower positioning groove 10-1 for positioning the connecting end of the test line 5 is provided on the first lower pressing plate 10, and a test line positioning groove 11-1 is provided on the first upper pressing plate 11, which cooperates with the test line positioning groove 10-1 to form a test line limiting cavity. The power supply module 21 is fixed on the first lower pressing plate 10.

[0034] The first lower pressing plate 10 is provided with a lower adapter line positioning groove 10-2 for limiting the second adapter line 20, and the first upper pressing plate 11 is provided with an upper adapter line positioning groove 11-2 that cooperates with the lower adapter line positioning groove 10-2 to form an adapter line limiting cavity.

[0035] The first guide assembly includes a first slide rail 12 fixed to the connecting plates 1-4 and a first slider 13 fixed to the first lower pressure plate 10 and matched with the first slide rail 12. The first drive cylinder 9 is located below the display 7. The cable limiting cavities for the test line and the second adapter cable are arc-shaped and symmetrically arranged to facilitate the layout of the test line and the adapter cable.

[0036] See attached Figure 3-5 , 8 and 9, the aforementioned second drive assembly includes a patch cord clamping assembly for securing the patch cord 6, a patch cord guide assembly disposed between the patch cord clamping assembly and the connecting plates 1-4 within the chassis 1, and a second drive cylinder 14 for driving the patch cord clamping assembly to move along the guide direction of the patch cord guide assembly. The second drive cylinder 14 is located below the connecting plates 1-4 and is connected to the patch cord clamping assembly via a drive plate 15 that passes through the strip-shaped holes 1-5 in the connecting plates 1-4. This design can reduce horizontal occupancy and thus the horizontal footprint of the device.

[0037] The adapter cable clamping assembly includes an adapter cable lower pressure plate 16 connected to the drive plate 15, an adapter cable upper pressure plate 17, and connecting bolts for connecting the adapter cable lower pressure plate 16 and the adapter cable upper pressure plate 17. A lower end positioning groove 16-1 for positioning the connection end of the adapter cable 6 is provided on the adapter cable lower pressure plate 16, and an upper end positioning groove 17-1 is provided on the adapter cable upper pressure plate 17, which cooperates with the lower end positioning groove 16-1 and forms a connection end limiting cavity of the adapter cable 6. The adapter cable guide assembly includes a second slide rail 18 fixed to the connecting plate 1-4 and a second slider 19 fixed to the adapter cable lower pressure plate 16 and matched with the second slide rail 18. In this embodiment, since the outer end of the USB module 2 has two or even more USB interfaces and the interfaces can be USB-A, USB-C, etc., a connection end limiting cavity corresponding to the number of interfaces is provided between the two adapter cable pressure plates.

[0038] The testing tool of this utility model operates as follows: After the device is powered on and initialized, the USB module 2 to be tested is placed into each positioning seat 3. A button on the chassis 1 is pressed to initiate testing. A rotating clamping cylinder presses the USB module 2 against the positioning seat 3. Then, the first and second drive cylinders 9 and 14 respectively drive the corresponding test cables 5 and adapter cables 6 to connect them to the USB module 2. The control circuit within the chassis 1 then tests the transmission speed and charging protocol via the test cables 5 and adapter cables 6, and displays the results on the display 7.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for protection of the utility model.
