A groove 2 is formed on the top of the comb plate body 1, and multiple convex comb teeth 6 are slidably arranged inside the groove 2. Fixing grooves 8 are formed on both sides of the convex comb teeth 6. A U-shaped groove 13 is formed on the inner side of the comb plate body 1, and two rotating shafts 14 are provided inside the U-shaped groove 13. The two rotating shafts 14 are symmetrically distributed with respect to the vertical center line of the comb plate body 1, and both ends of the two rotating shafts 14 are rotatably connected to the comb plate body 1. A pressing structure is provided between the two rotating shafts 14. Each of the two outer sides is fixedly connected to an extrusion block 15. Each of the two extrusion blocks 15 has an installation plate 16 on its outer side. Each of the two installation plates 16 has multiple fixing posts 17 fixedly connected to one side of the opposite side. One end of the fixing post 17 passes through the inner side of the U-shaped groove 13 and extends into the inside of the protrusion groove 2. The fixing post 17 is slidably connected to the comb plate body 1. The fixing post 17 is set inside the fixing groove 8. Each of the multiple fixing posts 17 has a spring 18 sleeved on its outer side. Both ends of the multiple springs 18 are fixedly connected to the comb plate body 1 and the two installation plates 16 respectively. The comb plate body 1 is provided with a heating structure.

[0024] The pressing structure includes two gears 19, which are fixedly connected to the outer side of one end of two rotating shafts 14. Both gears 19 are meshed with racks 20 on their outer sides. A connecting plate 21 is fixedly connected between the two racks 20. The top of the connecting plate 21 is provided with two sliding pillars 22. The bottom ends of the two sliding pillars 22 pass through the connecting plate 21 and are slidably connected to the connecting plate 21. Both ends of the sliding pillars 22 are fixedly connected to the comb plate body 1. A second spring 23 is sleeved on the outer side of the sliding pillars 22. Both ends of the second spring 23 are fixedly connected to the connecting plate 21 and the comb plate body 1, respectively. The pressing structure also includes a pressing column 24, which is fixedly connected to the bottom of the connecting plate 21. A circular groove is formed at the bottom end of the U-shaped groove 13. The pressing column 24 is set inside the circular groove and is slidably connected to the comb plate body 1.
