[0025] like Figure 6 As shown, the driving member 51 includes a central shaft 511, an upper seat 512, a side shaft 513 and a No. 2 spring 514. The central shaft 511 is slidably connected to the through hole 31, and the central shaft 511 is fixedly connected to the telescopic driving device 2. The upper seat 512 is fixed to the upper end of the central shaft 511, and a plurality of side shafts 513 are fixed to the peripheral side of the upper seat 512. The No. 2 spring 514 is sleeved on the outer side of the central shaft 511. The expansion member 52 includes a sliding shaft 521 and a clamping plate 522. The sliding shaft 521 is slidably connected to the slide slot 41. The clamping plate 522 is fixed to one side of the sliding shaft 521. The side shaft 513 corresponds to the sliding shaft 521. The inside of the slide slot 41 is fixedly connected to the perforated plate 42. The sliding shaft 521 is arranged in the hole of the perforated plate 42. The No. 1 spring 43 is fixedly connected to one side of the perforated plate 42. The outer side of the sliding shaft 521 is fixed with a limiting ring 5211.

[0026] The flange to be fixed is placed on the upper end surface of the receiving platform 3, and the telescopic drive device 2 is started, so that the central axis 511 drives the upper seat 512 to move downward and compresses the No. 2 spring 514. During the downward movement of the upper seat 512, the side axis 513 on the side of the upper seat 512 contacts the sliding shaft 521 and pushes the sliding shaft 521 to slide outward along the sliding groove 41, and at the same time compresses the No. 1 spring 43, and the clamping plate 522 on one side of the sliding shaft 521 expands outward.
