Multifunctional strength tester

The invention discloses a multifunctional strength tester which comprises fixing devices, a sensing testing device and strength testing accessories. The fixing devices comprise the lower limb fixing device and the universal fixing device; the sensing testing device comprises a fixing device connecting ring, a pull force sensing element, a display and a strength testing accessory connecting ring; the strength testing accessories comprise the upper limb strength testing accessory and the waist, back and lower limb strength testing accessory. The upper limb strength is measured by connecting the fixing devices, the sensing testing device and the upper limb strength testing accessory; the waist or back strength is measured by connecting the fixing devices, the sensing testing device and the waist, back and lower limb strength testing accessory; the lower limb strength is measured by connecting the universal fixing device, the sensing testing device and the waist, back and lower limb strength testing accessory. Accordingly, multiple testing instruments are integrated on one device, the strength of the different parts of a human body can be tested simultaneously, and meanwhile the strength of one or more joints in different angles can be tested.
