[0029] In a preferred embodiment, as Figure 3 shown, the clamping assembly includes a clamping plate 23 arranged inside the clamping groove 22. A conduit 29 is fixedly installed on the inner wall of the clamping groove 22. A connecting rod 27 is inserted into the conduit 29. A first return spring 28 is arranged at one end of the connecting rod 27 inside the conduit 29. The other end of the connecting rod 27 is fixedly connected to the outer surface of the clamping plate 23. Fixing is carried out by the clamping plate 23 in the clamping groove 22. When the clamping plate 23 is in the clamping state, one side connecting rod 27 will push inward, squeezing the internal first return spring 28.

[0030] In a preferred embodiment, as Figure 2 shown, a guide rod 24 is fixedly installed on the outer surface of one end of the first clamping frame 2. One end of the second clamping frame 21 is sleeved on the outer surface of the guide rod 24, and the second clamping frame 21 is slidably connected to the guide rod 24. A screw 25 is rotatably installed on the outer surface of the other end of the first clamping frame 2, and the other end of the second clamping frame 21 is threadedly connected to the screw 25. A motor 26 is fixedly installed on the outer surface of the first clamping frame 2, and one end of the output shaft of the motor 26 is fixedly connected to the screw 25. The motor 26 on the first clamping frame 2 drives the screw 25 at one end to rotate, causing the second clamping frame 21 to move outward along the guide rod 24, and then placing the ballpoint pen in the clamping groove 22.

[0031] In a preferred embodiment, as Figure 4 shown, the pressing plate assembly includes a pressing plate 33 arranged on one side of the side frame 31.

When conducting a test, place the paper on the placement table 3 and fix the paper through the pressing plate 33.

[0032] In a preferred embodiment, as Figure 5 shown, a mounting tube 35 is fixedly installed at the top of the side frame 31.

[0034] Refer to the attached instructions Figures 1-5 During the test, place the paper on the placement table 3 and fix the paper by the pressing plate 33. One end of the paper is connected to the traction mechanism. When fixing the test ballpoint pen, start the motor 26 on the first clamping frame 2 to drive the screw 25 at one end to rotate, so that the second clamping frame 21 moves outward along the guide rod 24. Then place the ballpoint pen in the clamping groove 22, and then drive the second clamping frame 21 to reset by the motor 26, so as to fix it through the clamping plate 23 in the clamping groove 22. When the clamping plate 23 is in the clamping state, the connecting rod 27 on one side will push inward to squeeze the first return spring 28 inside. During the test, the air cylinder 12 will drive the clamping frame to move back and forth, so as to drive the ballpoint pen to write and test on the paper. After writing, it is necessary to move the paper forward through the traction mechanism to change the writing position. Before moving the paper, it is necessary to turn off the electromagnet 39. The baffle loses the magnetic attraction of the electromagnet 39 and will be pushed upward by the second return spring 37, driving the slide plate 34 to slide upward along the chute 32, so that the pressing plate 33 loosens both sides of the paper. After the position adjustment is completed, start the electromagnet 39 again to fix the paper by the pressing plate 33.
