Abstract

The invention relates to the field of sports equipment, in particular to sports equipment for testing. In order to solve the problems that an existing seat body forward-bending test device cannot be well adapted to different crowds, the leg tightening steps are too complicated, looseness is generated easily for a long time, test data are inaccurate, and meanwhile, waist protection is insufficient in the test process, so that back sprain of a tester is easy to cause. The technical scheme of the invention comprises a base, a measuring ruler and the like, wherein the upper part of the front side of the base is provided with the measuring ruler for measuring the forward bending distance of the body. The invention realizes that the torsion spring drives the round roller to wind the fixing belt, so that the redundant fixing belt is wound on the round roller, thereby avoiding the influence on the fixing effect of the knee of the tester due to overlong fixing belt, realizing the fixation of the round roller and the fixing belt due to the meshing of the ratchet wheel and the pawl, avoiding the extension of the tension force of the fixing belt due to the arch of the leg, and further avoiding the influence on the accurate measurement effect.
