[0029] Rotate the turning handle 4 to drive the screw rod 3 to rotate, so that the two moving blocks 5 approach each other, and the ends of the two connecting rods 7 connected to the moving blocks 5 also approach each other accordingly. The other ends of the two connecting rods 7 act simultaneously to push the moving plate 8 and the clamping plates 10 connected to its top towards the two fixed plates 13. Then place the rubber part between the two fixed plates 13 and the two clamping plates 10. Then continue to rotate the turning handle 4. By the same principle, the two clamping plates 10 and the two fixed plates 13 clamp and fix the rubber part inside. Then carry out the hole expanding operation. After the hole expanding is completed, rotate the turning handle 4 in the reverse direction to separate the two clamping plates 10 from the two fixed plates 13, and then take out the hole-expanded rubber part. During the whole hole expanding process, the rubber part will not come off, improving the success rate of hole expanding. And the operation process is simple, convenient and fast, improving the hole expanding efficiency.

[0030] A baffle 14 is arranged between the two fixed plates 13. Insert plates 15 are fixedly connected to the outer walls on both sides of the baffle 14. Slots 16 are opened on the opposite surfaces of the two fixed plates 13. The insert plates 15 are located inside the slots 16.
