In the two cavities, two compression springs 32 are respectively fixedly connected. At the end of the compression spring 32 away from the housing 30, an upward thrust spring slider 33 is fixedly connected. At the end of the upward thrust spring slider 33 away from the compression spring 32, it is slidably connected to the first bearing 31. In the third partition plate 17, through holes are opened at positions corresponding to the two chutes. The two first bearings 31 can both slide left and right in the through holes. One end of the two second caps 20 close to the installation groove is respectively connected to the first bearing 31. Specifically, at one end of the two second caps 20 close to the installation groove, threaded holes are opened. Threaded holes are sleeved with bolts, and the bolts pass through the threaded holes and the through holes and are connected to the first bearing 31.

[0027] Further, referring to Figure 2 and Figure 4 As shown, in the middle of the outer side of the fourth partition plate 18, a second driving gear 34 connected to the second motor 16 is provided. Below the second driving gear 34, a second bearing 35 is arranged at intervals. Above the second bearing 35, a horizontal plate 36 is slidably connected. At the upper end of the horizontal plate 36, horizontal teeth meshing with the second driving gear 34 are provided. At the right side of the horizontal plate 36, a sliding block 37 is connected, and at its left side, a first limiting block 38 is connected; the sliding block 37 is horizontally slidably connected to the outer side of the fourth partition plate 18, that is, the sliding block 37 can slide horizontally on the fourth partition plate 18, and on the side of the sliding block 37 facing the fourth partition plate 18, two third bearings 39 are provided. One end of the two second caps 20 close to the sliding block 37 is respectively slidably sleeved on the two third bearings 39.

[0028] Further, positioning holes, a plurality of circular sliding holes and a plurality of arc-shaped sliding holes are formed in the third partition plate 17 and the fourth partition plate 18. Both ends of the first rotating shaft 24 are rotatably arranged in the positioning holes on both sides; second rotating shafts 41 are sleeved on the third driven gears 26 on both sides and the fourth driven gear 27 on the right side of the second driven gear 25. Both ends of the second rotating shaft 41 are slidably arranged in the arc-shaped sliding holes on both sides; the fourth driven gear 27 on the left side of the second driven gear 25 and the fifth driven gear 28 are both sleeved with third rotating shafts 42. Both ends of the third rotating shaft 42 are slidably arranged in the circular sliding holes on both sides; the fifth driven gear 28 on the right side of the second driven gear 25 is sleeved with a fourth rotating shaft 43. Both ends of the fourth rotating shaft 43 are respectively connected to two second caps 20; the second rotating shafts 41 arranged on the third driven gears 26 are respectively rotatably connected to the first cap 19 and the second cap 20. Both ends of the second rotating shaft 41 on the fourth driven gear 27 on the right side of the second driven gear 25 are respectively connected to the second cap 20. Both ends of the third rotating shaft 42 are respectively connected to the first cap 19.

[0029] By rotating the second motor 16, the second motor 16 drives the second driving gear 34 to rotate. During the rotation of the second driving gear 34, the horizontal plate 36 is driven to move left and right on the second bearing 35. When it is necessary to clamp the certificate, the horizontal plate 36 moves left on the second bearing 35. The horizontal plate 36 drives the sliding block 37 to slide left, and then pushes the two third bearings 39 to move left as well. During the leftward movement of the third bearings 39, the two second caps 20 are driven to rotate, and the two second caps 20 move towards each other. At the same time, the first bearing 31 in the spring assembly also moves left in the installation groove until it contacts the upward pushing spring slider 33. At this time, the compression spring 32 generates a downward acting force, which further pushes the second cap 20 to continue moving towards each other, thereby clamping the certificate, and the upward pushing spring in the upward pushing spring slider 33 is compressed, storing elastic potential energy; when it is necessary to loosen the certificate, the horizontal plate 36 moves right on the second bearing 35. The horizontal plate 36 drives the sliding block 37 to slide right, and then pushes the two third bearings 39 to move right as well. At the same time, the first bearing 31 also moves, and the two second caps 20 move away from each other. During this process, the upward pushing spring releases the stored potential energy, which further pushes the upward pushing spring slider 33 to reset, and the downward force of the compression spring 32 gradually decreases, which further drives the two second caps 20 to continue moving away from each other, thereby loosening the certificate; in the embodiment of the present invention, through the cooperative action of the upward pushing spring and the compression spring 32, it is ensured that the transmission device can clamp the certificate when transmitting the certificate, and the clamping stability is high. Also, through the bearing trigger mechanism, the clamping force can be controlled, thereby avoiding excessive pressure on the certificate.

[0030] In this embodiment, refer toFigure 4 As shown, second limit blocks 40 are symmetrically arranged at both the left and right ends inside the third partition plate 17 and the fourth partition plate 18, and the second limit blocks 40 are semi-cylindrical in shape; when the certificate enters and exits the transmission device, the semi-cylindrical limit blocks effectively limit the movement of the certificate and prevent the certificate from moving offset during the transmission process, thereby improving the transmission accuracy.
