[0046] According to some embodiments, referring to Figure 2 , the jig further includes a tool wrench 04 disposed on the support frame 03, with a movable end connected to the test plate 01. The jig further includes an electromagnet 05 placed on the test plate 01 for starting the Internet of Things module to be tested.

[0047] According to some embodiments, the tool wrench 04 is fixed on the support frame 03 and connected to the test plate 01 through its movable end, controlling the up and down movement of the test plate 01. Pulling the control end of the tool wrench 04 moves the test plate 01 towards the carrier plate 02; pulling the control end of the tool wrench 04 moves the test plate 01 in the opposite direction.

After testing is completed, the control end of the tool wrench 04 is pulled up, so that the movable end of the tool wrench 04 drives the test board 01 to move in the opposite direction of the carrier board 02 until the top pin 0104 is disconnected from the carrier board 02, so that the carrier board 02 is powered off. By controlling the tool wrench 04, the power supply control of the carrier board 02 is realized. After a single test is completed, the overall power supply of the test system does not need to be turned off, only the power supply of the carrier board 02 needs to be turned off by pulling up the tool wrench 04, which facilitates the replacement of the Internet of Things module to be tested, and the operation is more simple, and the safety and operation efficiency are improved.
