出装置。[Claims for Utility Model Registration] (1) An operating pipe is loosely fitted on the outside of the gas extraction pipe, and a first stopper support is formed at the tip of the operating pipe, and a suitable position on the outside of the gas extraction pipe is provided. a second stopper support part is configured, and an elastic cylindrical stopper that can freely protrude in the radial direction by compression in the axial direction is interposed and supported between the first and second stopper support parts, A moving mechanism for relatively moving the operating pipe and the gas extraction pipe in a direction to narrow the gap between the first and second plug supports; A gas extraction device characterized in that a holding mechanism that holds the holding mechanism at a narrow interval and a holding release mechanism that releases the holding mechanism are provided at appropriate positions. (2) The moving mechanism, the holding mechanism, and the holding/releasing mechanism are constructed of a lead screw formed on the outside of the gas extraction pipe and a female screw threadedly engaged with the lead screw. Retrieval device. (3) The moving mechanism, the holding mechanism, and the holding release mechanism each have a driving piece that is loosely fitted into the actuating tube, and an engagement driving part that pushes the driving piece against the elasticity of the return spring. A utility model consisting of a drive shaft, a locking piece that loosely fits into the actuating pipe and supports one side so as to be rotatable, and a locking spring for maintaining the locking piece in an inclined state. A gas extraction device according to registered claim 1.
