The movable tool is used for the center tube of the movable tubing retrievable downhole safety valve. The movable tool can effectively solve the problem that the downhole safety valve cannot be opened and closed normally due to wax and scaling on the center tube of the downhole safety valve.

After the center tube of the downhole safety valve is movable, the normal opening and closing function of the downhole safety valve can be realized to maintain the normal production of oil and gas wells.
