[0021] Working principle: When using the utility model for leg support, first adjust the support height of the calf as needed, and then adjust the angle of the thigh and calf support, that is, rotate the worm 13 through the handle 14, the worm 13 drives the first bracket 11 through the worm wheel 12, and the first bracket 11 deflects on the support 1, so that one end of the first bracket 11 is raised to the required height; then directly push one end of the second bracket 15 upward, so that the second bracket 15 is deflected on the first bracket 11 to the required angle, and the ratchet 22 in the shaft sleeve 21 has a supporting effect on the first wedge 28, so that the second bracket 15 can be kept at the desired height. Angular position, when the second bracket 15 deflects, the housing 23 thereon rotates accordingly, the first wedge block 28 is squeezed by the ratchet 22 to slide inwardly along the through slot 25, and then automatically resets under the elastic force of the spring 27. If the second bracket 15 needs to be reset, the button 210 at the first bracket 11 can be pressed to make the push block 213 push the second wedge block 29, and the first wedge block 28 on the second wedge block 29 moves accordingly, and the first wedge block 28 slides inwardly along the through slot 25 and compresses the spring 27. When the first wedge block 28 is completely out of the ratchet 22, the second bracket 15 can be reset; then the second wedge block 28 can be reset by pushing the second wedge block 29 upward. One end of the third bracket 17 makes the third bracket 17 deflect to the required angle on the second bracket 15, and the supporting effect of the ratchet 22 on the first wedge 28 can keep the third bracket 17 at this angle. When the third bracket 17 deflects, the housing 23 thereon rotates accordingly, and the first wedge 28 is squeezed by the ratchet 22 to slide inward along the through groove 25, and then automatically resets under the elastic force of the spring 27. If the third bracket 17 needs to be reset, the button 210 at the second bracket 15 can be pressed, so that the push block 213 pushes the second wedge 29, and the first wedge 28 on the second wedge 29 is reset accordingly. The first wedge block 28 slides inwardly along the through groove 25 and compresses the spring 27. When the first wedge block 28 is completely disengaged from the ratchet 22, the third bracket 17 can be reset. Among them, the first supporting cloth 16 is used to support the calf part, the second supporting cloth 18 is used to support the thigh part, the flange 24 is used to limit the shell 23, the positioning groove 26 is used to cooperate with the protrusion 212 to position the button 210, the elastic block 211 is used to realize the connection between the button 210 and the shell 23, the heel pad 19 is made of foam cotton to support the heel, and the foot support plate 110 is used to support the sole of the foot to prevent the foot from sagging.
