Put the clock battery 25 into the battery receiving slot of the fixed structure 2, and make its positive and negative poles correspond to the positive terminal 14 and the negative pole of the fixed terminal 7 in the fixed structure 2 respectively. Press the pressure rod 131 in the clamping mechanism 1 to drive the pressure plate 13, the positive terminal 14 and the first connecting line 4 to press down. When they are fully in contact with the clock battery, the test can be carried out. The upper positive pole is connected to the tangent circuit through the positive terminal 14 and the first connecting line 4 through the wiring hole 17, and the lower negative pole is connected to the fixed terminal 7 and then to the negative pole in the second connecting line 5 to connect to the tangent circuit.
