[0030] Referring to Figure 5As shown in the figure, specifically, an auxiliary structure 7 is provided on the lower surface of the support plate 3. The auxiliary structure 7 includes a second spring 71. The second spring 71 is fixedly connected to the lower surface of the support plate 3. The lowermost end of the second spring 71 is fixedly connected with a pull plate 72. A positioning rod 76 slides inside the second spring 71. The upper end of the positioning rod 76 is fixedly connected to the support plate 3. The lower end of the positioning rod 76 slides through the pull plate 72. A fixed rod 73 is fixedly connected to the upper surface of the pull plate 72. The upper end of the fixed rod 73 is fixedly connected with a top block 74. A reserved hole 77 is provided on the support plate 3 corresponding to the position of the top block 74. The size of the reserved hole 77 is larger than that of the top block 74. A limiting frame 75 is fixedly connected to the lower surface of the support plate 3. The pull plate 72 slides inside the limiting frame 75. After the measurement of the polarizer is completed, the pull plate 72 can be pulled upward to eject the top block 74 from the reserved hole 77 of the support plate 3, and the polarizer can be lifted by means of the top block 74, assisting the operator to quickly transfer the measured polarizer from the support plate 3.

[0031] Working principle: When it is necessary to measure the polarizer, slide along one side of the support plate 3 to above the support plate 3, and ensure that the length and width of the polarizer respectively abut against the slide rail 401 and the positioning plate 5. When the polarizer is slid, the polarizer will push the pressure ball 413. The pressure ball 413 will move upward under extrusion. At this time, the slide rod 412 will slide upward, and the first spring 415 will give a pulling force to the top plate 414 to keep the pressure ball 413 in contact with the polarizer all the time. At this time, the thickness of the polarizer can be read through the scale on the slide rod 412. At this time, the slider 402 can be directly slid to drive the connecting plate 405 to move, so that the backing plate 406 on one side of the connecting plate 405 abuts against one side of the polarizer. At this time, the length of the polarizer can be obtained according to the position of the connecting plate 405 corresponding to the scale groove 6. When it is necessary to measure the width of the polarizer, the polarizer can be directly rotated, and the width of the polarizer can be measured again by using the connecting plate 405. When it is necessary to measure the tilt angle of the polarizer, first rotate the screw rod 408 to disengage the screw rod 408 from the disc 403, then rotate the connecting plate 405 to make the backing plate 406 of the connecting plate 405 abut against the inclined side of the polarizer, and then rotate the screw rod 408 in the reverse direction to make the screw rod 408 squeeze against the anti-slip pad 409 of the disc 403 by means of the thread. At this time, the tilt angle of the polarizer can be obtained according to the position of one side of the connecting plate 405 corresponding to the protractor 410;

[0032] After the measurement of the polarizer is completed, the pull plate 72 can be directly pulled upward. At this time, the pull plate 72 will drive the fixed rod 73 and the top block 74 to move upward. The top block 74 will eject from the reserved hole 77 of the support plate 3, and the top block 74 will lift the polarizer on the support plate 3. At this time, the second spring 71 is in a compressed state. Then, the polarizer can be directly removed from the support plate 3. Then, the pull plate 72 is released, and the second spring 71 will give the pull plate 72 a downward elastic force, so that the top block 74 returns to the lower part of the support plate 3 again. At this time, other polarizers can be placed on the support plate 3 again for measurement. By setting the auxiliary structure 7, after the measurement of the polarizer is completed, the polarizer can be quickly lifted, and the operator's hand can reach in through the lifted gap and then take away the polarizer.
