A muscle stretching rehabilitation apparatus according to claim 1, wherein: a third supporting plate (32) is fixedly connected to one side of the L-shaped plate (1) far away from the first supporting plate (3), the top of the third supporting plate (32) is fixedly connected with two positioning plates (33), two through holes are arranged on the positioning plate (33), second positioning rods (34) penetrate through the through holes, one ends of the two pairs of second positioning rods (34) close to each other are fixedly connected with massage plates (35), a plurality of massage blocks (36) are arranged on the side wall of the massage plate (35), the massage blocks (36) are of rubber pad structures, the bottom of the third supporting plate (32) is fixedly connected with a bidirectional motor (37), the other end of each pair of the second positioning rods (34) is fixedly connected with a moving block (38), a threaded hole is formed in the moving block (38), a second threaded rod (39) is connected with the threaded hole in an internal thread manner, one end of the second threaded rod (39) is fixedly connected to an output shaft of the bidirectional motor (37).

7. The muscle stretching rehabilitation device according to claim 6, wherein: the two massage blocks (36) are arranged symmetrically with respect to the central axis of the third support plate (32).

8. A muscle stretching rehabilitation apparatus as claimed in any one of claims 1 to 7, including the steps of:

s1, firstly, all the electrical elements are externally connected with a power supply, when leg muscles need to be stretched, a crank (25) can be shaken, the crank (25) drives a first threaded rod (24) to rotate, then a threaded block (23) and an adjusting block (27) are driven by the first threaded rod (24) to move towards the direction far away from a first supporting plate (3), further the distance between a second rotating block (11) and a first rotating block (10) is adjusted, and after the distance is proper, the ankle can be seated on the first supporting plate (3) and placed in a limiting groove on a first limiting block (15).

S2, starting the transmission motor (17), the transmission motor (17) drives the second gear (18) to rotate, then the second gear (18) drives one of the first gears (16) to rotate, and then the first gear (16) drives the other first gear (16) to rotate in the opposite direction, so that the pair of the first rotating block (10) and the second rotating block (11) respectively rotate in two directions, and then the leg is stretched to be used.

And S3, when the hand muscle needs to be stretched, the hand muscle can be stretched by holding the U-shaped block (29) by hand and placing fingers on one side of the movable block (30), then the fingers press the movable block (30) and compress the spring (31), and then the movable block (30) is pushed to restore the original position through the elastic reset action.

S4, when the waist muscles need to be stretched, the two first rotating blocks (10) and the second rotating blocks (11) are driven to be close to each other through the transmission motor (17), the first gear (16) and the second gear (18), then the second supporting plate (19) and the second fixing rod (20) are placed on the first rotating blocks (10) and the second rotating blocks (11), then a user lies prone on the first supporting plate (3) and the second supporting plate (19), leans against the front body on the backup plate (5), at the moment, the hydraulic cylinder (8) is started, and the hydraulic cylinder (8) pushes the backup plate (5) to slowly rotate towards the direction far away from the L-shaped plate (1), so that the waist muscles are stretched.

S5, when the waist needs to be massaged, the user can sit on the third supporting plate (32), then the two-way motor (37) is started, the two-way motor (37) drives the two second threaded rods (39) to rotate, then the moving block (38), the second positioning rod (34) and the massage plate (35) are driven to move back and forth through the second threaded block (23), and then the waist is massaged through the massage block (36).
