The lower transmission structure 332 includes a rotating shaft 3321 and a plurality of driving wheels 3322. The rotating shaft 3321 is rotatably disposed at the bottom of the base 32 and extends in the longitudinal direction. The driving wheel 3322 is fixedly arranged on the rotating shaft 3321, and the driving wheel 3322 and the rotating shaft 3321 are arranged coaxially. A plurality of driving wheels 3322 are arranged at intervals along the axial direction of the rotating shaft 3321. A through hole 322 is arranged on the base 32 at a position corresponding to the driving wheel 3322. The top of the driving wheel 3322 protrudes from the top surface of the base 32 through the through hole 322. The plurality of driving wheels 3322 are located below the plurality of driven wheels 3312 in a one-to-one correspondence. The driving module 333 is connected to the rotating shaft 3321, and is used to drive the rotating shaft 3321 and the driving wheel 3322 to rotate. The driving wheel 3322 and the driven wheel 3312 are both rubber wheels.

[0064] The temporary certificate is clamped between the driving wheel 3322 and the driven wheel 3312. The driving module 333 drives the rotating shaft 3321 to rotate, thereby driving the driving wheel 3322 to rotate, and at the same time drives the driven wheel 3312 to rotate, so that the temporary certificate is transported in the horizontal direction. The above structure is compact and also makes the temporary certificate transmission stable.

[0065] Please refer to Figure 5 , Figure 6 and Figure 7The transmission assembly 33 also includes two groups of connection structures 334, which are respectively arranged at the two longitudinal edges of the upper cover 31.
