Multipurpose stand for experiment

Abstract

The present invention relates to the multipurpose stand for experiment.

1 . A multipurpose stand for experiment comprising: 
 a pedestal ( 25 );    a tie rod ( 27 ) vertically erected on said pedestal ( 25 );    position-controlling members ( 15 ), inserted into said tie rod ( 27 ), which can easily move vertically and rotationally;    fixing members of vertical position ( 17 ), closely adhered to the bottom face of said position-controlling members ( 15 ), which fix the position of said position-controlling members by clamp screws ( 20 );    fixing bars of experimental instruments ( 37 ,  38 ), one end of which are adhered to said position-controlling members ( 15 ) and the other of which can set kinds of experimental instruments;    and thermometer-putting bars ( 24 ) adhered to the spar-parts ( 37   b,    38   b ) of said fixing bars of experimental instruments ( 37 ,  38 ).    
     
     
         2 . The multipurpose stand for experiment according to  claim 1 , wherein each of said position-controlling members ( 15 ) comprises; a metal plated through bore ( 15   a ) in the shape of cylinder; trapped holes ( 15   b ) on the top face of said position-controlling member ( 15 ); grooves on the upper side face ( 15   c ); one trapped hole on the lower side face ( 15   d ); and clamp screws ( 20 ) inserted into said trapped holes ( 15   b,    15   d ) for the purpose of fasting said fixing bars of experimental instruments ( 37 ,  38 ) and the position-controlling members ( 15 ).  
     
     
         3 . The multipurpose stand for experiment according to  claim 1 , wherein each of said thermometer-putting bars ( 24 ) comprises; a control unit ( 24   a ) inserted into the spar-part ( 37   b,    38   b ) of said fixing bar of experimental instrument ( 37 ,  38 ); a clamp screw ( 24   c ) to fix said control unit ( 24   a ); and a thermometer-putting portion ( 24   b ), in the shape of inverted L, assembled with said control unit ( 24   a ).
