First, the vice lock frame 2 is inserted into the main lock frame 1, and the positioning block 10 on the vice lock frame 2 slides on the clamping block 12 in the inner wall of the main lock frame 1 through the clamping groove 11. In this process, the positioning block 10 extrudes the extrusion positioning plate 8, the telescopic rod 13 is retracted, and the strong spring B 14 is compressed.

[0037] The anti-loosening assembly is arranged on the outer wall of the main lock frame 1.

[0038] The clamping assembly is arranged on the outer walls of the main lock frame 1 and the vice lock frame 2.

[0039] As shown in Figure 3 and Figure 5 , as a preferred embodiment, on the basis of the above-mentioned mode, further, the anti-loosening assembly comprises a fixed plate 4 fixedly connected to the outer wall of the main lock frame 1, a limiting frame 5 slidably connected to the outer wall of the fixed plate 4, a strong spring A 9 fixedly connected to the outer wall of the fixed plate 4 and fixedly connected to the limiting frame 5, a plurality of limiting grooves 7 arranged on the outer wall of the limiting frame 5, and a limiting frame 6 slidably connected to the outer wall of the limiting groove 7 and fixedly connected to the vice lock frame 2.
