[0027] The effect achieved by the entire embodiment 1 is that the two driving motors 113 are started, and the two threaded rods 114 are moved through the two connecting blocks 115, and the other ends of the two threaded rods 114 are rotated inside the two fixed frames 104, so that the printing component 116 installed between the two connecting blocks 115 can move upward, and then the two electric push rods 117 are started to drive the two T-shaped sliders 103 to move inside the two slide grooves 102, so that the printing component 116 that moves up and down can move forward and backward.
