the double grooved pulley (57) and the left second driven grooved pulley (513) are in transmission connection through a first driving belt (514), the first driven grooved pulley (55) and the right second driven grooved pulley (513) are in transmission connection through a first driven belt (515), the double grooved pulley (57) and the second driven grooved pulley (619) are in transmission connection through a second transmission belt (621), the first transmission gear (613) and the second transmission gear (618) are in transmission connection, the first transmission grooved pulley (614) and the second transmission grooved pulley (619) are in transmission connection through a first transmission belt (615), and the second driving gear (915) and the worm (912) are in transmission connection;

the using method comprises the following steps:

when the device is used, firstly, the speed reducing motor (56) is started, the speed reducing motor (56) can drive the double grooved wheels (57) to rotate, the first driving belt (514) can be conveniently driven to rotate through the rotation of the double grooved wheels (57), the first driving belt (514) can conveniently drive the first driving gear (511) and the driven gear (512) to simultaneously rotate through the rotation of the double grooved wheels (57), the first driven belt (515) can be conveniently driven to rotate through the rotation of the driven gear (512), the roller (53) can be driven to rotate through the rotation of the first driven rod belt (515), the driving belt (54) can be driven to rotate through the rotation of the roller (53), so that the blind can conveniently walk on the driving belt (54), and then, the first air cylinder (62) can conveniently drive the first driving gear (613) to be meshed with the second driving gear (618) through the starting of the first air cylinder (62), meanwhile, the start of the first air cylinder (62) can also conveniently drive the positioning block (79) in the positioning device (7) to be clamped with the inner cavity of the positioning groove (712), so that the rotating wheel (711) can be conveniently fixed, the first transmission gear (613) and the second transmission gear (618) can be fully meshed by fixing the rotating wheel (711), then the start of the second air cylinder (81) is controlled, the second air cylinder (81) can conveniently drive the second pull rod (83) to move, the positioning block (79) on the first pull rod (714) can be conveniently driven to be separated from the inner cavity of the positioning groove (712) by the movement of the second pull rod (83), so that the return of the positioning block (79) can be conveniently completed, the forward and reverse rotation of the speed reduction motor (56) can conveniently drive the worm (912) to perform forward and reverse rotation through the transmission connection of the worm (915) and the second drive gear (915), the positive and negative rotation of worm (912) just can drive the positive and negative rotation of threaded rod (97), just can make fall way (92) conveniently go up and down through the positive and negative rotation of threaded rod (97), then just can make the guardrail adjust the height at will through the lift of fall way (92), just so can make blind person straight line running gear can adapt to the blind person of co-altitude not, at last through starting third cylinder (1001), third cylinder (1001) can drive third stopper pole (1002) and move, just can conveniently drive adaptation pole (1003) through the motion of third piston rod (1002) and move, just can conveniently accomplish the degree of difficulty of training blind person straight line walking through the motion of adaptation pole (1003).
