[0022] As shown in Figures 3-5 The telescopic buffer part comprises a top pipe 1, a middle pipe 2 and a bottom pipe 3 which are nested in sequence and arranged in sequence along the vertical direction. The relative positions among the top pipe 1, the middle pipe 2 and the bottom pipe 3 are adjusted to realize the telescoping of the overall telescopic buffer part and the adjustable height of the bottom opening. The top part of the middle pipe 2 is fixedly connected with a first magnetic attraction ring 4 which can be attracted to the top side or the bottom side of the top pipe 1. The stable positioning of the relative positions between the middle pipe 2 and the top pipe 1 after the adjustment is realized by the attraction between the first magnetic ring and the top pipe 1. The top part of the bottom pipe 3 is fixedly connected with a second magnetic attraction ring 5 which can be attracted to the bottom side of the top pipe 1 or the bottom side of the middle pipe 2. The stable positioning of the relative positions between the bottom pipe 3 and the top pipe 1 or the middle pipe 2 after the adjustment is realized by the magnetic action of the second magnetic ring, so as to ensure that the telescopic buffer part can adjust the position of the bottom opening thereof according to the requirements.
[0023] As shown in Figures 3-5As shown, the top side and the bottom side of the top pipe 1 are fixedly connected with the first ring body 6 which is attracted to the first magnetic ring 4 by welding, the top side and the bottom side of the middle pipe 2 are fixedly connected with the second ring body 7 by welding, the first magnetic ring 4 is fixed to the top wall of the second ring body 7 on the top side, and the first magnetic ring 4 and the top wall of the second ring body 7 are fixed by adhesive, the top side and the bottom side of the bottom pipe 3 are fixedly connected with the third ring body 8 by welding, the second magnetic ring 5 is fixed to the top surface of the third ring body 8 on the top side, and the second magnetic ring 5 and the third ring body 8 are fixed by adhesive.
[0024] As shown in the Figures 3-5 As shown, the transverse cross-sectional shape of the first ring body 6, the second ring body 7, the third ring body 8, the top pipe 1, the middle pipe 2 and the bottom pipe 3 is rectangular, which can realize stable restriction of the relative rotation process of the top pipe 1, the middle pipe 2 and the bottom pipe 3, ensure the process of relative sliding of the top pipe 1, the middle pipe 2 and the bottom pipe 3 more stable and smooth, make the process of adjusting the relative position of the top pipe 1, the middle pipe 2 and the bottom pipe 3 more stable, and ensure the use of the whole structure more convenient.

The elastic buffer part includes two symmetrical magnetic elastic deformation plates 9 which are made of magnetic rubber material and have good elastic deformation performance, so that the magnetic elastic deformation plates 9 can buffer the impact force of the cuttings falling on the surface of the magnetic elastic deformation plates 9 and reduce the splashing degree of the cuttings. The two magnetic elastic deformation plates 9 are surrounded by a material passing groove 10, and the magnetic elastic deformation plates 9 have magnetic properties, so that the magnetic elastic deformation plates 9 can exert a magnetic attraction force on the cuttings which can be attracted by a magnet, further enhancing the buffering performance of the whole structure, and further reducing the probability of splashing of the cuttings. When the amount of cuttings discharged per unit time is excessive, the gravity of the cuttings will cause the magnetic elastic plate to be bent, so that the opening of the material passing groove 10 will gradually increase, so that the cuttings can better pass through the magnetic elastic deformation plate and fall into the chip truck and be collected;
