A handheld cutting device comprises a first body and a second body that are arranged to be opposite to and spaced from each other. One of the bodies comprises a cutting blade, while the other body comprises a stop corresponding in position to the cutting blade. The two bodies are both provided with press-down sections, which can be pressed down to make the two bodies approach toward each other, thereby causing the cutting blade to move toward the stop to produce a shearing action. The two bodies receive a restoration element connected between them to provide an effect of position restoration after the two bodies are pressed down and approach each other.一種手持式刀具具有呈相對間隔設置之第一本體及第二本體,其中一本體上設有一刀刃部,另一本體上對應上述刀刃部的位置則有一擋部,且兩本體上分別具有按壓部,可供按壓並令兩本體相對靠近,進而使刀刃部朝擋部移動形成剪切動作。而兩本體之間設有一連接於二者之回復元件,提供兩本體經按壓而相對靠近後的復位效果。1...第一本體11...第一按壓部12...固定環部13...定位柱14...導引柱15...刀刃部151...刀座1512...凸柱1513...螺帽152...刀片153...螺絲2...第二本體21...第二按壓部22...定位柱23...導引柱24...擋部241...容置槽3...彈簧S...剪切空間
