[0022] By means of the above structure: when working, the buffer component inside the cotton block 1 provides buffering support for the cotton block 1. When the cotton block 1 is under pressure, the support frame 4 is also under pressure. Since the connection parts of the support frame 4 are all hinged structures, as the support frame 4 is under pressure, the angle of the support frame 4 will increase, thereby driving the support blocks 5 to approach each other, and the support blocks 5 compress the buffer spring 6. At this time, the buffer spring 6 rebounds under the action of its own elastic force, thereby offsetting part of the pressure to achieve buffering of the cotton block 1, preventing the cotton block 1 from being overly compressed, resulting in its rebound performance gradually deteriorating, or even unable to rebound.

[0023] like Figure 4 As shown, a fixing plate 7 is provided at the bottom of the cotton block 1, and a fixing frame 8 is provided at the top of the outer wall of the cotton block 1, the fixing plate 7 is matched with the fixing frame 8, the fixing plate 7 and the fixing frame 8 are both square structures, the fixing plate 7 and the fixing frame 8 are both made of rubber, a card groove 13 is provided on the outer wall at the top of the fixing plate 7, the depth of the card groove 13 is less than the thickness of the fixing plate 7, the card groove 13 is matched with the cotton block 1, the fixing plate 7 supports the cotton block 1, and the fixing frame 8 and the fixing plate 7 cooperate with each other to further improve its pressure resistance.

[0024] like Figure 3As shown, control blocks 9 are arranged around the outer wall of the top of the fixing plate 7 and around the outer wall of the bottom of the fixing frame 8, buffer rods 10 are arranged on the outer walls on both sides adjacent to the control block 9, a control groove 11 is provided on the inner wall of the control block 9, the buffer rod 10 is slidably connected to the inner wall of the control groove 11, the buffer rod 10 is a dumbbell-shaped structure, the outer walls on both sides adjacent to the control block 9 are provided with holes adapted to the buffer rod 10, the inner wall of the control groove 11 is provided with a support spring 12, the end of the support spring 12 is connected to the buffer rod 10, when the cotton block 1 is compressed, the fixing frame 8 at the same height thereof is compressed accordingly, at this time, the buffer rod 10 squeezes the support spring 12, thereby further providing buffering support through the support spring 12, and the support spring 12 cooperates with the buffer spring 6 to improve the buffering performance of the cotton block 1, the cotton block 1 is not easily deformed, and the service life of the cotton block 1 is improved.

[0025] How this utility works:

[0026] When working, the buffer component inside the cotton block 1 provides buffer support for the cotton block 1. When the cotton block 1 is compressed, the support frame 4 is also compressed. Since the connection parts of the support frame 4 are all hinged structures, as the support frame 4 is compressed, the angle of the support frame 4 will increase, thereby driving the support blocks 5 to approach each other, and the support blocks 5 compress the buffer spring 6. At this time, the buffer spring 6 rebounds under the action of its own elastic force, thereby offsetting part of the pressure to achieve buffering of the cotton block 1, preventing the cotton block 1 from being overly compressed, resulting in its rebound performance gradually deteriorating, or even unable to rebound;

[0027] When the cotton block 1 is under pressure, the fixed frame 8 at the same height is also under pressure. At this time, the buffer rod 10 squeezes the support spring 12, thereby further providing buffer support through the support spring 12. The support spring 12 cooperates with the buffer spring 6 to improve the buffering performance of the cotton block 1, make the cotton block 1 less likely to deform, and increase the service life of the cotton block 1.
