[0033] Specifically, the first electric push rod 3 is activated, and the output end of the first electric push rod 3 drives the connecting chamber 13 to move, thereby adjusting the height of the terminal 14. The terminal 14 and the connection end of the terminal 17 are correspondingly distributed. The drive motor 8 is activated, and the output shaft of the drive motor 8 drives the screw 9 to rotate. Through the threaded connection between the screw 9 and the sliding plate 4 and the sliding connection between the sliding plate 4 and the sliding groove 10, the screw 9 drives the two moving plates 2 to move relative to each other through the sliding plate 4.

[0034] Please see Figures 1 to 3 In this embodiment, the placement plate 1 is provided with a limiting component for restricting the wiring terminal 17. The limiting component includes two limiting plates 5, both of which are placed on the top surface of the placement plate 1. The top surface of the placement plate 1 has two support grooves 18. The bottom surface of each of the two limiting plates 5 is fixedly connected to a support plate 6, one end of which extends into the support groove 18. The top surface of each of the two limiting plates 5 is fixedly installed with a second electric push rod 7. The output end of the second electric push rod 7 passes through the limiting plate 5.

The sliding connection between the support plate 6 and the support groove 18 supports the limiting plate 5, improving its stability. The second electric push rod 7 is activated. The output end of the second electric push rod 7 moves the pressure plate 15 downward, causing the rubber pad 16 to fit together with the terminal 17, thus fixing the terminal 17. The first electric push rod 3 is activated... The output end of 3 drives the connection chamber 13 to move, thereby adjusting the height of the terminal 14. Through the action of the clearance groove 12, the cable 11 can move up and down. The terminal 14 and the access end of the terminal 17 are correspondingly distributed. The drive motor 8 is started, and the output shaft of the drive motor 8 drives the screw 9 to rotate. Through the threaded connection between the screw 9 and the sliding plate 4 and the sliding connection between the sliding plate 4 and the sliding groove 10, the screw 9 drives the two moving plates 2 to move relative to each other through the sliding plate 4, so that the terminal 14 is inserted into the interior of the terminal 17 for testing, thereby improving the testing efficiency.
