[0023] Please refer to Figures 2-4The top of each of the two clamping plates 11 is slidably connected with an adjusting seat 13, and the opposite side of each of the two connecting plates 8 is fixedly installed with two first electric push rods 12. The output ends of the two first electric push rods 12 installed on the two connecting plates 8 are opposite to each other. Each of the first electric push rods 12 is connected with an external power supply and is provided with a same power control switch. The output ends of the two first electric push rods 12 extend to one side of the adjusting seat 13. The bottom of the clamping plate 11 and the top of the base plate 10 form a folding angle.

[0024] Please refer to Figures 2-4 The crease deepening assembly 9 comprises two mounting plates 91. The bottom of the two mounting plates 91 is jointly installed with a mounting seat 92. The two sides of the mounting seat 92 are fixedly installed with two second electric push rods 93. The four second electric push rods 93 are connected with an external power supply and are provided with a same power control switch. The output ends of the second electric push rods 93 on the two sides of the mounting seat 92 are opposite in extension direction.
