A neck strength measuring apparatus includes an installation frame, a sensing structure, a display and an adjusting structure fixed on the installation frame. The adjusting structure includes a longitudinal screw and a transverse screw, and the longitudinal screw and the transverse screw are disposed in perpendicular to each other. The sensing structure has an adjusting rod connecting with the adjusting structure, a sensor provided on the adjusting rod and a force component assembly connected with the sensor. And the display is electrically connected with the sensor. Thereby, human neck strength will be measured for knowing the muscle condition.本發明係為一種頸部肌力量測裝置,包括安裝架、固定在安裝架上的調整結構、感測結構及顯示器。調整結構包含縱螺桿及橫螺桿,縱螺桿及橫螺桿呈相互垂直設置。感測結構包含連接調整結構的調整桿、設置在調整桿上的感測器及連接感測器的受力組件。顯示器電性連接感測器。據此量測人體頸部之肌力,以得知頸部之肌力狀態。1‧‧‧量測裝置10‧‧‧安裝架20‧‧‧調整結構21‧‧‧縱向螺桿組211‧‧‧縱螺桿212‧‧‧承接板213‧‧‧縱向調整座214‧‧‧操控螺桿215‧‧‧縱向轉盤22‧‧‧橫向螺桿組221‧‧‧橫螺桿222‧‧‧橫向調整座223‧‧‧橫向轉盤224‧‧‧驅動座30‧‧‧感測結構31‧‧‧調整桿32‧‧‧感測器33‧‧‧受力組件331‧‧‧擋板332‧‧‧緩衝墊333‧‧‧固定帶40‧‧‧顯示器50‧‧‧座椅60‧‧‧束縛帶
