PROBLEM TO BE SOLVED: To provide a multifunctional auxiliary tool used for X-ray measurement.SOLUTION: An auxiliary tool 40 includes a first block 42 and a second block 44. When they are horizontally connected, the auxiliary tool 40 is inserted under two lower limbs, which allows the lower limbs to be put in a knee bending position naturally. When the two blocks 42 and 44 are vertically connected, a cover structure 68 is covered over the upper part of a holding structure 66. The combination of the two structures allows two feet to be put and kept in a position in which they are twisted inward. The auxiliary tool 40 can be used as a chair or stepstool. |
