At the same time, the thickness of the silicone pad 203 is related to the pipe diameter. Silicone pads 203 of different thicknesses can be selected according to different pipe diameters to increase the clamping force. Furthermore, the silicone pad 203 is soft in texture, which avoids the clamping block 2 from damaging the pipe during the process of clamping the pipe.
