[0022] When implemented, burette rack is more common in water quality analysis, soil detection and other experimental processes in the field of water conservancy engineering, and the weight change of the liquid in the burette main body 4 cannot be monitored by the traditional burette rack, so that the titration process is not accurate. The weighing indicator main body 10 can be placed on the top of the support rod 2, and then slowly lowered. During the falling process of the weighing indicator main body 10, the butt joint block 12 and the U-shaped seat 14 can be moved. When the bottom end of the butt joint block 12 moves to the inside of the connecting block 6 through the plug-in hole 9, the butt joint block 12 can extrude the inclined surface of the clasp seat 8. When the clasp seat 8 is extruded, the reset spring 7 can be compressed. When the reset spring 7 is compressed to the maximum extent, the bottom end of the butt joint block 12 can slide to the bottom position of the plug-in hole 9. At this time, the clasp seat 8 can be reset by the reset spring 7.
