The jaws of the two-jaw chuck 8 are fixedly connected to the second mounting plate 9.

[0020] Among them, the first mounting plate 7 can fix the two-jaw chuck 8 and the second mounting plate 9, and then the two-jaw chuck 8 can drive the limiting mechanism 4 and the telescopic mechanism to contract, thereby fixing and clamping the corrugated tube.

[0021] See also Figure 1 and Figure 3 The limiting mechanism 4 includes a third mounting plate 10, a limiting seat 11, a first limiting groove 12 and a second limiting groove 13.
