The other end of the adjustment shaft 504 extends to the inside of the guide channel 509 and is fixed with a spring. The guide gear 506 and the outer wall of the adjusting shaft 504 are fixed with symmetrically distributed cams 505. When the adjusting shaft 504 rotates, the two cams 505 can squeeze the two protection plates 503 at the same time, so that the two protection plates 503 move out of the protection channel 502 at the same time, thereby increasing the protection area. A guide plate 507 is fixed to the inner wall of the annular seat 1. A guide rack 508 is provided on the side wall of the guide plate 507 close to the guide gear 506. The guide gear 506 and the guide rack 508 are meshed and connected with each other, so that the protection plate 503 can be automatically extended during the upward movement of the protection platform 501, thereby increasing the protection area.

[0037] A limiting groove 510 is provided on the lower surface of the protection platform 501, and a limiting channel is provided on the outer wall of the annular seat 1.

[0038] This solution has the following working process: when a person performs leg rehabilitation training, the person enters the annular seat 1 through the space between the support plates 2, so that the person holds the handle 7 with his hands, and the legs are respectively located on the two side areas of the protection platform 501, and then performs leg walking rehabilitation training. During the walking process, the universal wheels 12 arranged at the bottom of the annular seat 1 can move with the person's walking, and can perform walking rehabilitation training in various angles and directions, with high flexibility. At the same time, the induction plate 8 is installed on the person's back through the soft belt 9, and the soft belt 9 is connected by Velcro. At this time, the induction plate 10 and the induction plate 2 11 are within the mutual sensing range, and the person can move by holding and pushing the handle 7 so that the annular seat 1 follows the movement, which can prevent the person from moving. The entire center of gravity of the body is pressed on the leg support. When the legs slip, the leg muscles are insufficient, the walking is unstable, etc., the person's body will tilt or fall down, and the induction plate 2 11 and the induction plate 1 10 fixed on the back of the person will be out of the sensing range. When the single-chip microcomputer receives this signal, the single-chip microcomputer controls the drive motor 410 to start, and the drive motor 410 drives the adjustment gear 411 to rotate. The meshing transmission between the adjustment gear 411 and the adjustment rack 412 drives the annular plate three 405 to rotate, and the annular plate three 405 drives the extrusion plate 406 to rotate. The extrusion plate 406 extrude the arc surface of the adjustment plate 403, so that the adjustment plate 403 drives the annular plate two 401 to move downward, and the annular plate two 401 drives the vacuum suction The plate 402 moves downward and contacts the ground, and at the same time, the single chip microcomputer controls the vacuum pump to start, and evacuates the vacuum suction cup 402, so that the vacuum suction cup 402 is stably connected to the ground. At this time, the position of the annular seat 1 is fixed, and at the same time, the annular plate 3 405 will drive the transmission plate 413 to move during the rotation, and the transmission plate 413 drives the transmission rack 414 to move, and the transmission rack 414 and the transmission gear 416 are meshed to drive the limit shaft 415 to rotate, and the limit shaft 415 drives the limit gear 513 to rotate, and the meshing transmission between the limit gear 513 and the limit rack 512 drives the limit plate 511 to move online, and the limit plate 511 drives the protection platform 501 to move upward, and the protection platform 501 drives the adjustment shaft 504. The guide gear 506 and the guide rack 508 are meshed and driven to drive the adjusting shaft 504 to rotate. The adjusting shaft 504 drives the two cams 505 to rotate. The cams 505 squeeze the two protection plates 503 at the same time, so that the two protection plates 503 extend out of the protection channel 502. When the protection platform 501 moves upward, the protection area is increased, so that the personnel sit on the protection platform 501 and the surface of the protection plate 503, reducing the degree of falling or falling of the personnel and effectively protecting them. When the sensing sheet 1 10 and the sensing sheet 2 11 are continuously sensing, the single chip microcomputer controls the vacuum pump to relieve the pressure on the vacuum suction cup 402, so that the vacuum suction cup 402 is released from fixation.Then the single chip microcomputer controls the driving motor 410 to rotate in the opposite direction. According to the above transmission principle, the extrusion plate 406 no longer extrudes the adjustment plate 403. Under the elastic force of the reset spring 408, the annular plate 401 drives the vacuum suction cup 402 to move upward, so that the vacuum suction cup 402 returns to the initial position. At the same time, according to the above transmission principle, the protection platform 501 moves downward, so that the protection platform 501 returns to the initial position. During the downward movement of the protection platform 501, the protection plate 503 automatically enters the protection channel 502, and then the personnel continue the rehabilitation training.
