An arm vibration damping device, comprising a housing (9), a longitudinal vibration damping module (1) and a transverse vibration damping module (2), the longitudinal vibration damping module (1) comprising a longitudinal motor (11), a support frame (12) and a mounting frame (13), the mounting frame (13) comprising a U-shape element (131) and a mounting element (132) the support frame (12) being located between the U-shape element (131) and two arms, the longitudinal motor (11) being in a transmission connection with the U-shape element (131) a transverse motor (21) of the transverse vibration damping module (2) being in a transmission connection with the support frame (12) via a reverse mechanism (22) the transverse motor (21), the support frame (12), the U-shape element (131) and the mounting element (132) being arranged along an axial direction of the transverse motor (21). Vibration can be cancelled through movements in a longitudinal direction and in a direction of the longitudinal vibration damping module, and the use of two arms of the U-shape element ensures the stability of the whole mounting frame and a components fitted thereon in a longitudinal movement.本新型公開了一種減輕手臂振動影響的裝置,包括殼體、縱向減震模組及橫向減震模組。縱向減震模組用於帶動配件進行縱向減震,橫向減震模組用於帶動縱向減震模組及配件進行縱向減震;縱向減震模組包括縱向電機、支撐架及安裝架,安裝架包括U形件及安裝件;支撐架位於U形件的兩支臂之間,縱向電機傳動連接於U形件;橫向減震模組的橫向電機通過變向機構傳動連接於支撐架;橫向電機、支撐架、U形件與安裝件沿橫向電機的軸向排布設置。通過縱向及縱向減震模組兩個方向的移動來抵消震顫,利用U形件兩個支臂可保證整個安裝架及配件在縱向移動的穩定性。各主要部件沿裝置的中心軸線方向排布,整個裝置結構佈局合理,方便使用者手持使用。1‧‧‧縱向減震模組11‧‧‧縱向電機12‧‧‧支撐架121‧‧‧基座122‧‧‧傳動杆13‧‧‧安裝架131‧‧‧U形件132‧‧‧安裝件2‧‧‧橫向減震模組21‧‧‧橫向電機22‧‧‧變向機構221‧‧‧主動錐齒輪222‧‧‧從動錐齒輪9‧‧‧殼體91‧‧‧固定柱
