[0023] like Figure 1-Figure 3 As shown, it also includes a push-up assembly, which includes a slider 1401, a stepper motor 1402, a threaded rod 1403, a guide rod 1404 and a push block 1405. The front of the temporary storage box 5 is symmetrically provided with sliders 1401 that can slide left and right along it and can be detached and separated. The bottom surface of the lower slider 1401 is installed with a stepper motor 1402 by bolts.
