To reduce the weight, can be made hollow. For ease of assembly and disassembly custody, may be made in dismantling the threaded rod and hanging with holes .① machine with standard taper shank test rods. material CRWMN or T10A, rod heat-treatment is C59, must be qualitatively processed .② cylinder machine test stick. stick material is a T10A or seamless, heat-treated to C59.
