The outer surface of the second clamping block 8 is in active contact with the outer surface of the capstan rope wheel 3. The top surface of the first clamping block 7 is installed with a top column 10, and the top surface of the top column 10 is in active contact with the outer surface of the pressure sensor 12. The pressure sensor 12 detects that the pressure of the top column 10 is too large, and the pressure sensor 12 is not damaged.
