[0035] In actual use, the movable block 1, guide rod 14, support spring 7 and base 6 are set, so that when people press the positioning block 11 against the high-pressure oil pipe, the threaded head 4 is aligned with the thread in the high-pressure oil pipe. Through the above operation, people can use the positioning block 11 to achieve pre-alignment during the installation process, avoiding the problem of deviation of the hydraulic pipe joint during the installation process, and the installation efficiency is higher.
