Manually operating the external controller can adjust the operating status of the first motor 4, the second motor 7, the third motor 10, and the hydraulic cylinder 17 respectively. All of the above are existing technologies. When using this device, first start the third motor 10 through the external controller. The third motor 10 drives the adjusting shaft 11 and the limiting shaft 12 to rotate. The adjusting shaft 11 can... The first adjusting block 13 slides left and right within the limiting shell 9, bringing the two first adjusting blocks 13 closer together. The second adjusting block 14 and the second clamping block 16 move synchronously with the first adjusting blocks 13.

The third motor 10 is started again, which drives the two... An adjusting block 13 moves closer, allowing the test clamp to open and clamp onto the terminal of the equipment to be tested. The device can clamp the test clamp using an adjustable first clamping block 15 and a second clamping block 16, and control the opening and closing of the test clamp. The tilt angle and direction of the test clamp can be adjusted using a rotatable mounting plate 6 and a support plate 8.
