 a rotating button screwed in the button hole of the lower telescopic pipe and having a inner end mounted in one of the inserting holes of the upper telescopic pipe; and 
   a sliding kneeler slidably mounted on the track frame and having
 a pin mount having
 a bottom extending downwardly out of the track bars; 
 a rear side; 
 a front side; 
 two sidewalls; and 
 a pinhole formed through the sidewalls of the pin mount below the track bars; and 
 
 an inserting pin mounted in the pinhole of the pin mount, abutting against the track bars and having two ends respectively extending out of the sidewalls of the pin mount below the track bars. 
   
     
     
         2 . The waist-training machine as claimed in  claim 1 , wherein
 the lower telescopic pipe is a rectangular-hollow pipe;   the upper telescopic pipe is a rectangular-hollow pipe;   each inserting hole of the upper telescopic pipe has a diameter; and   the upper telescopic pipe has a through hole formed through the rear side of the upper telescopic pipe, aligning with one of the inserting holes and having a diameter larger than the diameters of the inserting holes.   
     
     
         3 . The waist-training machine as claimed in  claim 2 , wherein
 the track bars are curved-cylindrical bars;   the pin mount is mounted on the bottom of the sliding mount between the track bars and has a positioning hole formed through the front side of the pin mount and communicating with the pinhole;   the inserting pin has
 a central segment mounted in the pin mount between the sidewalls of the pi mount; and 
   a threaded hole formed in the central segment of the inserting pin and aligning with the positioning hole of the pin mount; and   the sliding kneeler has
 a sliding mount slidably mounted between the track bars of the track frame and having
 a bottom; 
 a top; 
 two opposite sidewalls; and 
 two axle holes formed through the opposite sidewalls of the sliding mount at an interval; 
 
 two wheel axles respectively and rotatably mounted in the axle holes of the sliding mount and each wheel axle having
 two ends respectively extending out of the opposite sidewalls of the sliding mount; and 
 two rollers respectively mounted around the ends of the wheel axle, respectively and rotatably mounted on the track bars of the track frame and each roller having
 an external surface; and 
 an annular groove formed around the external surface of the roller and abutting the corresponding track bar; 
 
 
 a positioning bolt mounted through the positioning hole of the pin mount and screwed in the threaded hole of the inserting pin to enable the inserting pin to abut the track bars to prevent the rollers separating from the track bars; and 
 a kneeler securely mounted on the top of the sliding mount. 
   
     
     
         4 . The waist-training machine as claimed in  claim 3 , wherein
 the track frame has a buffering block mounted on the front face of the connecting block; and   the track bars are curved-cylindrical bars, are securely mounted on the connecting block beside the buffering block; and   the pin mount has a buffering face formed on the rear side of the pin mount and selectively abutting the buffering block of the track frame.
