Example 1: as shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, a first quantitative measuring tool for the degree of movement of a wedge joint is provided, a sliding groove plate 1 is a right angle plate, a bottom plate of the sliding groove plate 1 is connected with a left plate 5 through a left fixing screw 4, the top of the other end of the left plate 5 is provided with a downward bending shape, a sliding groove 3 is arranged in the vertical direction of one side of the straight plate of the sliding groove plate 1, a scale plate 2 is a right angle plate 8, the bottom plate of the scale plate 2 is connected with a right plate 8 through a right fixing screw 7, the top of the other end of the right plate 8 is provided with a downward bending shape, a sliding plate 6 is arranged in the vertical direction of one side of the straight plate of the scale plate 2, the sliding plate 6 is provided with scales, the sliding groove 3 is in an arc concave shape, the section of the sliding plate 6 is in an arc convex shape (convex shape or a plurality of circles), and the arc concave shape is matched with the arc convex shape in size and shape, and the sliding groove 3 can be movably connected with the sliding plate 6.

The cross section of the sliding plate 6 is a convex arc (most of a circle), one side of the sliding plate 6 is connected with the straight plate 9, the other end of the straight plate 9 is connected with the scale plate 2, and the width of the scale plate 2 is about 5-6mm.

Or the section of the sliding plate 6 is a circle with a chord, the chord is connected with the straight plate 9, the other end of the straight plate 9 is connected with the scale plate 2, and the width of the scale plate 2 is about 5-6mm.

The sliding plate 6 is inserted in the sliding groove 3, the left plate 5 and the right plate 8 wrap the upper parts of five toes, the scale plate 2 and the sliding groove plate 1 are pinched to move up and down, and the scale size of the sliding plate 6 is read.

Example 2: as shown in fig. 1, 2, 3, 4 and 5, the first quantitative measuring tool for the activity degree of the plantar wedge joint is portable and lightweight, and is made of soft metal (copper or aluminum) to increase the plasticity, so that the first quantitative measuring tool for the activity degree of the plantar wedge joint is more attached to the surface of the skin. And adopt screw (left set screw 4 and right set screw 7) to carry out the fixed of metal sheet (slip frid 1 and left board 5 and scale board 2 and right board 8), its purpose is in order to carry out the change of metal sheet to adapt to different foot types, also can prevent the metal sheet fatigue fracture because of moulding many times simultaneously.
