The two connecting plates 85 are moved toward the silicone sleeve 81 through the bidirectional screw rod 82, so that the fixed rod 88 passes through the through groove 87 and enters the corresponding fixed groove 86. When the fixed groove 86 moves upward, the rubber pad 13 first contacts the end of the fixed groove 86. During the continuous movement of the fixed rod 88, the slide bar 12 slides inside the slide groove 1, and the slide bar 1 2 presses down the first spring 11 to make the first spring 11 produce elastic contraction. When the rubber pad 13 presses against the end of the fixing groove 86 and gradually contacts the top of the fixing rod 88, the first elastic sheet 14 produces elastic bending. The inner wall of the fixing groove 86 is pressed against by multiple first elastic sheets 14.

[0025] like Figure 3 and Figure 4As shown, a second elastic sheet 2 is fixedly connected to the middle of the first elastic sheet 14; the second elastic sheet 2 is arranged in an arc shape; a through hole 21 is opened in the middle of the first elastic sheet 14 and the second elastic sheet 2; elastic ropes 22 are fixedly connected to both ends of the second elastic sheet 2; the other end of the elastic rope 22 passes through the middle of the through hole 21 and is fixedly connected to the middle of the slide bar 12; during operation, when the slide bar 12 slides into the inside of the slide groove 1, the two ends of the second elastic sheet 2 are pulled by the elastic rope 22, so that the two ends of the second elastic sheet 2 are elastically bent, and the end of the elastic rope 22 forms a gripping force against the inner wall of the fixing groove 86, and a stable fixing effect can be effectively formed by bending the end of the elastic rope 22 against the inner wall of the fixing groove 86. The gripping force formed by the bending of the elastic rope 22 can tightly grip the inner wall of the fixing groove 86, which can effectively provide stronger connection force and stability, and effectively improve the performance of the overall structure fitting the inner wall of the fixing groove 86.
[0026] like Figure 3 and Figure 4 As shown, a plurality of groups of rubber blocks 3 are fixedly connected to the middle of the second elastic sheet 2; the plurality of groups of rubber blocks 3 are equidistantly distributed in the middle of the second elastic sheet 2; the plurality of groups of the second elastic sheet 2 are fixedly connected to the side away from the first elastic sheet 14; during operation, when the elastic rope 22 bends, the rubber blocks 3 come into contact with the inner wall of the fixing groove 86, and the friction between the elastic rope 22 and the inner wall of the fixing groove 86 is increased by the rubber blocks 3.

[0030] During operation, the silicone sleeve 81 is inserted from one end of the roller core 8 to make the fixed groove 86 and the through groove 87 coincide with each other, and the handle 84 is held to rotate the bidirectional screw rod 82. The two connecting plates 85 are moved toward the silicone sleeve 81 through the bidirectional screw rod 82, so that the fixed rod 88 passes through the through groove 87 and enters the corresponding fixed groove 86. When the fixed groove 86 moves upward, the rubber pad 13 first contacts the end of the fixed groove 86. During the continuous movement of the fixed rod 88, the slide rod 12 slides inside the slide groove 1, and at the same time, the slide rod 12 presses down on the first spring 11, so that the first spring 11 produces The first elastic sheet 14 is elastically bent when the rubber pad 13 is pressed against the end of the fixing groove 86 and gradually contacts the top of the fixing rod 88. The first elastic sheet 14 is pressed against the inner wall of the fixing groove 86 by a plurality of first elastic sheets 14, and the inner wall of the fixing groove 86 is filled by a plurality of first elastic sheets 14, so that the fixing rod 88 cannot shake in the inner wall of the fixing groove 86. The insertion rod 83 is inserted into the corresponding limiting groove 80 to fix the bidirectional screw rod 82. When the silicone sleeve 81 is disassembled, the insertion rod 83 is taken out, and the bidirectional screw rod 82 is rotated again to make the two connecting plates 85 close to each other, so that the fixing rod 88 moves. When the sliding rod 12 slides into the inside of the slide groove 1, the two ends of the second elastic sheet 2 are pulled by the elastic rope 22, so that the two ends of the second elastic sheet 2 are elastically bent, and the end of the elastic rope 22 forms a gripping force on the inner wall of the fixed groove 86. When the elastic rope 22 is bent, it contacts the inner wall of the fixed groove 86 through the rubber block 3, and the friction between the elastic rope 22 and the inner wall of the fixed groove 86 is increased by the rubber block 3. One end of the connecting pipe 42 is connected to the air pump, and the air pump is used to The pump discharges the airflow to the inside of the roller core 8 through the exhaust pipe 4. When the airflow enters the roller core 8, it takes away the hot air flow and discharges the airflow inside the roller core 8 through the exhaust hole 43. When the roller core 8 is working and rotating, the connecting tube 41 is rotated at the end of the exhaust pipe 4 to make the connecting tube 42 stationary, and the sleeve 5 is inserted from one end of the roller core 8 and twisted to fix the sleeve 5 on one end of the roller core 8.
