[0037] As Figure 2 and Figure 6 ​As shown, the fastening mechanism 6 comprises a mounting box 61, a hand wheel 62, a cam 63, a mounting plate 64, a compression spring 66, a V-shaped seat 68 and a pair of fastening pressure seats 69. Two sides of the mounting box 61 are fixedly provided with connecting blocks 611. The mounting box 61 can slide on the lathe bed 1 through the sliding fit of the connecting blocks 611 and the lathe bed 1. The hand wheel 62 is threadedly connected to the mounting box 61. The cam 63 is installed at the output end of the hand wheel 62 and located in the mounting box 61. The mounting plate 64 is slidingly arranged in the mounting box 61. The compression spring 66 is arranged between the mounting plate 64 and the inner bottom wall of the mounting box 61. The V-shaped seat 68 is installed at the upper end of the mounting box 61. The fastening pressure seats 69 are connected between the mounting plate 64 and the moving plate 67 which is slidingly connected to the mounting box 61. The pair of fastening pressure seats 69 are symmetrically arranged above the V-shaped seat 68.

[0038] In order to further ensure that the mounting plate 64 can move smoothly, a pair of limiting rods 65 for the sliding of the mounting plate 64 are arranged in the mounting box 61. The pair of limiting rods 65 are respectively arranged at the two sides of the cam 63.

[0039] As shown in Figure 2 and Figure 5 The lower end of the connecting block 611 is provided with a sliding block 612 which is slidingly fitted with the corresponding first sliding groove 11. The first sliding groove 11 is provided with a second sliding groove 12.
