positioning slot 82 b and the rotation of the rotatable displaceable part 40 also drives the second blade seat 32 to displace along the second blade guide groove 36 hence resulting in making adjustment to the height of the second blade 321 of the second blade seat 32 that protrudes outside of the second gap a 2 also in this example a wrench is secured to the main body 10 the wrench 200 can be used to lock bolts following is a description of first operations of the coaxial cable stripper 100 the rotation of the rotatable displaceable part 40 causes the extension to rotate which drives the first polygonal cylinder 411 to rotate inside the first polygonal hole the rotation of the first polygonal cylinder 411 pushes the first polygonal hole 81 upward or downward which causes the first blade seat 31 to displace along the first blade guide groove 35 which further pushes the first blade 311 of the first blade seat 31 upward or allows the first blade 311 of the first blade seat 31 to move downward hence resulting in making adjustment to the height of the first blade 311 which protrudes outside of the first gap a 1 the second spring 22 of the shaft body 30 will simultaneously push against the first blade seat 31 and the shaft body 30.
