A plurality of hollow feed screws having male threads on the outer periphery and female threads on the inner periphery and having different diameters.A small diameter feed screw is inserted inside a diameter 9 feed screw to create an adjacent feed screw. The screws are rotatably screwed together, a regulating means is provided for regulating the relative axial movement of the adjacent feed screws, and the winding directions of all the male and female screws are the same. A feed screw unit and a plurality of hollow cylinders with different diameters are concentrically engaged with each other so that they cannot rotate in the circumferential direction but can slide only in the axial direction, and each hollow cylinder has a relative relationship with an adjacent hollow cylinder. A hollow cylinder regulating means is provided for regulating the amount of movement in the axial direction, and a relative relationship between the female thread of the outermost feed screw of the feed screw unit and the male thread of the outermost feed screw of the feed screw unit is provided in the innermost hollow cylinder. The feed screw unit is inserted into the inside of the pipe unit, and the male thread of the outermost feed screw of the feed screw unit is inserted into the innermost part of the pipe unit. It is characterized by being screwed into the female thread of the hollow cylinder, fixing the outermost hollow cylinder of the pipe unit to the fuselage, and rotating the innermost feed screw to expand and contract the feed screw unit and the pipe unit. A telescopic drive device. 2. A utility model registration request characterized in that the regulating means is provided on the inner and outer peripheries of the feed screws and is constituted by steps that mutually engage with the feed screws adjacent to each feed screw. The telescoping drive device according to scope 1. 3. The telescopic drive device according to claim 1, wherein the regulating means is constituted by a retaining ring attached to one end of the inner periphery of the feed screw. 4. The hollow cylinder regulating means is configured by providing each hollow cylinder of the pipe unit with a slit that is closed at both ends, and providing a pin that engages with the slit in the hollow cylinder adjacent to the outside. A telescopic drive device according to claim 1, characterized in that it is a utility model.
