The apparatus for measuring power of a metatarsophalangeal joint of a foot according to claim 2, wherein the rotary member includes a connecting shaft, bearings are provided at both ends of the connecting shaft, and the mounting portion includes a first mounting groove in which the bearings are received so that the first mounting groove restricts movement of the bearings.

4. The apparatus according to claim 3, wherein the connecting rod extends through the connecting shaft to the detecting element, so that the connecting shaft restricts the movement of the connecting rod in the horizontal direction.

5. The apparatus according to claim 2, wherein the housing is fastened with a cover plate, the cover plate is provided with a mounting hole, and one end of the connecting rod extends through the mounting hole and extends out of an end surface of the cover plate.

6. The apparatus according to claim 2, wherein the connecting structure further comprises a hook and/or a hook detachably connected to the connecting rod, and the toes of the foot to be measured are hooked on the hook or the hook, so that the metatarsophalangeal joint force of the foot to be measured is transmitted to the detecting element through the connecting rod.

7. The apparatus for measuring the metatarsophalangeal joint strength of a foot according to claim 6, wherein the connecting rod has a fixing hole at one end, and the hook and/or the hook has a connecting rod, and the fixing hole and the connecting rod are fixedly inserted into each other.

8. The apparatus according to claim 6, wherein the housing is provided with a locking groove, and one end of the hook abuts against the locking groove to restrict rotation of the hook.

9. The apparatus according to claim 2, wherein the detecting member comprises a stress sensor, and a receiving groove is formed in the housing, and one end surface of the stress sensor is fixed to the receiving groove and the other end surface of the stress sensor abuts against or is separated from the connecting rod.

10. The apparatus according to claim 9, further comprising a controller and a display element, wherein the controller is electrically connected to the stress sensor and the display element, respectively, so that the display element can monitor the foot metatarsophalangeal joint strength detection data in real time.

11. The apparatus according to claim 1, wherein the support structure comprises a baffle plate and a fixing plate movably connected to each other, and the relative positions of the baffle plate and the fixing plate are adjusted to fit different foot sizes to be measured.

12. The apparatus for measuring the strength of metatarsophalangeal joint according to claim 11, wherein the fixing plate has an adjustment hole and the baffle plate has screw holes at both ends thereof, the adjustment hole and the screw holes being fixed by screws to fixedly connect the baffle plate and the fixing plate.
