The invention discloses a portable full working condition loading device for a power cutter frame. The full working condition loading device comprises a clamping portion 6 and a clamping body. The clamping body is provided with a first bevel gear 7-2 and a circular arc guide rail module that are arranged at the same axis. The circular arc guide rail module includes a circular arc guide rail 8-1 and a sliding block 8-2 that are in sliding connection. A loading device is arranged on the sliding block and includes one pair of axial power head loading devices 9, a common cuter head loader 10, anda radial power head loader 11. Compared with the prior art, the portable full working condition loading device has the beneficial effects that: the reliability test device can be applied to differenttypes of cutter holders and the universality is high; only the loading mechanism of the simulated working condition needs to be switched for replacing a test cutter holder; and the adjustment becomessimple and convenient and is easy to operate.
