The invention discloses a wrist power simulation training device. The wrist power simulation training device comprises a safety housing, a transfer bar, a power apparatus, a support, a speed regulator, an arc-shaped groove, a simulation cutter and a transmission groove, wherein the transfer bar and the power apparatus are installed inside the safety housing, the power apparatus is composed of a transmission connecting rod, a rotation shaft, a rotation wheel and a motor, the transfer bar and the transmission connecting rod are in rolling connection through a rolling bearing, the speed regulator is arranged at the top portion of the safety cap, the speed regular is electrically connected with the power apparatus, the speed regulator is composed of a intermediate gear, a low gear, a high gear and a switch, the simulation cutter is composed of a connection fixation rod, a simulation cutter body and a simulation cutter handle, and the connection fixation rod is in rolling connection with the transfer bar through a rolling bearing. The wrist power simulation training device is scientific and reasonable in structure and convenient and safe to operate. An automatic speed regulation function is realized through three-gear speed change and same gear of the speed regulator according to a wrist jittering frequency, and the learning speed and the operation safety of a trainee are greatly improved.
