Second limit grooves 18 are provided on both side surfaces of the connecting block 17. A fixing seat 19 is fixedly installed below the connecting block 17. The second limit grooves 18 provided on both sides of the connecting block 17 can be fine-tuned on the fixing seat 19, and then the connecting block 17 is fixed by means of threads. This adjustment method can facilitate the gray card test module 14 to be aligned with the test slot 11 below the connecting plate 10 for light measurement, and record the reflected light of the gray card test module 14. At the same time, the gray card test module 14 and the fixing block 15 are directly mounted on the pin 16 on the connecting block 17. This disassembly method is more convenient and quicker than the threaded method, and is convenient for the staff to carry out maintenance and replacement.

[0024] like Figure 1 and Figure 2 As shown, the bracket 2 is arranged on one side of the mounting plate 1, and the first limiting groove 3 is opened in front of the bracket 2. The bracket 2 is movably connected to the mounting plate 1. Through the setting of the bracket 2 and the first limiting groove 3, the height can be adjusted on the mounting plate 1, and then the bracket 2 is fixed by a threaded connection, so as to adjust the white card label test module 8 in conjunction with the watch test.

[0025] like Figure 1 and Figure 2 As shown, the cylinder 4 is fixed in front of the bracket 2, the fixing plate 5 is fixed at the lower end of the cylinder 4, and the fixing plate 5 is movably connected to the bracket 2. The setting of the cylinder 4 pushes the fixing plate 5 and the white card label test module 8 below to test the watch.

[0026] like Figure 1 and Figure 2 As shown, a white card label test module 8 is fixedly arranged below the connecting seat 7. The number of white card label test modules 8 is three. By setting three groups of white card label test modules 8, it is convenient to test three watches at one time, thereby improving the test efficiency.

The purpose of adjustment can be coordinated with the position of the watch, so that the watch can be accurately tested with a gray card.

[0029] The working principle of the utility model is as follows: firstly, the external power supply is turned on, and then the mounting plate 1 is installed together with the test machine. Then, according to the height that the white card label test module 8 needs to be adjusted, the first limiting groove 3 opened on the front surface of the bracket 2 is aligned with the thread groove on the surface of the mounting plate 1. Then, the bracket 2 is moved up and down on the mounting plate 1. After the movement is adjusted to a suitable overall height, the bracket 2 is fixed to the mounting plate 1 by means of a threaded connection. Then, the connecting block 17 above the fixing seat 19 is adjusted forward and backward on the fixing seat 19 through the second limiting grooves 18 opened on both sides of the connecting block 17 according to the position tested by the watch. When it is adjusted to a suitable position, the connecting block 17 is fixed by means of a threaded connection. Then, the gray card test module 14 and the fixing block 15 are connected. The gray card test module 14 is positioned by inserting the pin 16 on the connecting block 17, and then the dial 13 is placed in the fixture module 12, and the dial 13 is clamped and positioned by the fixture module 12. Then the cylinder 4 switch can be turned on to drive the fixing plate 5, the connecting seat 7 and the white card label test module 8 to descend. When it descends to the top of the watch, the cylinder 4 switch is turned off, and the NFC label test is performed on the watch surface. The gray card test module 14 below is set, and the fixing seat 19 and the gray card test module 14 are lifted and lowered by the driving component, so that the gray card test module 14 is lifted and lowered to the test slot 11 below the watch, and the watch is measured. The reflected light of the gray card test module 14 is recorded, and the use process of the watch PPG board test fixture is completed.
