Problems solved by technology

Although the categories described in these patent technologies have related to the drilling sampling mechanism and sampling soft bag for drilling and sampling of lunar soil, they do not relate to a kind of tubular fabric for wrapping samples mentioned in the present invention (soft bag is included in the scope of the present invention) (inside) the device and method for measuring the smoothness of drawing that is socketed on the wall of the heat pipe, and does not involve the device and method for measuring the smoothness of pulling out of the tubular fabric used under different temperature conditions and socketed on the wall of the heat pipe. In particular, it does not involve the expression of the axial friction force generated when the tubular fabric is sleeved on the heat pipe wall and the smoothness and smoothness attenuation rate of the tubular fabric during the folding and drawing process
