[0020] like Figure 1-3 As shown, the main body 11 is a circular shell, which is characterized in that: two first openings 12 are opened on both end surfaces of the main body 11, a driving shaft 13 is rotatably connected in the first opening 12, and an external thread 14 is provided on the driving shaft 13; one end surface of the main body 11 is fixedly connected to a motor 15, and the output shaft of the motor 15 is fixedly connected to the driving shaft 13, and a laying auxiliary mechanism is provided on the driving shaft 13, and the laying auxiliary mechanism includes a limit assembly and a flattening assembly, and the limit assembly and the flattening assembly both slide relative to the main body 11.

[0021] The two end surfaces of the main body 11 are further provided with first slots 16 , in which elastic bent plates 17 are fixedly connected. The elastic bent plates 17 are provided with first arc surfaces 18 at one end close to the main body 11 and away from the first slot 16 , and the elastic bent plates 17 are made of rubber material.

[0022] The limiting assembly includes a first limiting plate 20 and two first sliding blocks 22. The first sliding blocks 22 are fixedly connected to the first limiting plate 20. First sliding grooves 21 are provided on the two inner side surfaces of the main body 11. The first sliding blocks 22 slide relative to the first sliding grooves 21. Two second openings 23 are provided on the first limiting plate 20. The second openings 23 are provided with internal threads. The second openings 23 are threadedly connected to the driving shaft 13. An embossing 32 is provided on one end surface of the flattening block 30 away from the elastic member 25, and second arc surfaces 31 are provided on both sides of the embossing 32.

[0023] The flattening assembly includes two elastic members 25, a second limiting plate 26 and a flattening block 30. One end of the elastic member 25 is fixedly connected to the second limiting plate 26, and the other end of the elastic member 25 is fixedly connected to the flattening block 30. Two third openings 24 are provided on the first limiting plate 20, and the elastic member 25 is slidably connected to the third openings 24. Two second sliding grooves 28 are provided on one side of the main body 11 close to the second limiting plate 26.
