The present invention provides a tamper machine handle safety brake device, which is mainly disposed on the handle, and includes: a fixing seat, a handle and a sliding block, the fixing seat is fixed on the handle to form a fixed portion, and the fixing seat is pivoted at one end The other end of the sliding block is pivotally connected to one end of the sliding block, and the other end of the sliding block is pivotally connected to the handle； The pulley is disposed at one end of a clutch line, and the other end of the clutch line is connected to an idler mechanism for controlling the power wheel mechanism； accordingly, by pressing and holding the handle, the clutch line pulls the idler mechanism to abut the parallel connection power wheel mechanism, thereby urging The power output can drive the cultivating knife to rotate； on the contrary, when the handle is released, the restoring action of the idler mechanism will cut off the coupling power wheel mechanism, and the cultivating blade can naturally stop due to no power, thereby avoiding bad handling or components. The accident caused by the failure.本創作係提供一種耕耘機把手安全制動裝置，主要設置於該把手上，包括有：一固定座、一握柄及一滑動塊，該固定座鎖固在把手上形成固定，該固定座一端樞接該握柄之一端，另一端貫設有一滑槽且內設一滑輪，該滑輪之兩端樞接於該滑動塊之一端，該滑動塊之另一端則樞接於握柄上；又該滑輪穿設一離合器線之一端，該離合器線另一端連接於控制動力輪機構之惰輪機構；據此，透過按住握柄，令離合器線拉動惰輪機構抵頂並聯結動力輪機構，促使動力輸出得以帶動耕耘刀轉動；反之，當放開握柄時，該惰輪機構之回復作用將切斷聯結動力輪機構，耕耘刀因無動力提供自然停止，可避免因不良之操控或零組件之失效而產生的意外。
