[0031] Example 2

[0032] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a rubber sheath 7 is fixedly connected to the outer side wall of the clamping block 22 .

[0033] In this embodiment, when the four turning handles 21 drive the clamping blocks 22 on both sides of the rod to approach the rod, the clamping blocks 22 come into contact with the rod through the rubber sheath 7.
