請參閱第2、3圖，舉例而言，該電動工具10驅動該螺絲起子頭16將一鎖設元件50鎖設至一預定位置。當該鎖設元件50已呈鎖緊狀態，則該螺絲起子頭16會與該預定位置所產生的抗力會使得輸入該電動工具10的該驅動電流產生一突波，且該電動工具10所具備的離合機構(未顯示)將使得該輸出端18的輸出的扭力無法繼續轉動該螺絲起子頭16及該鎖設元件50。Please refer to FIGS. 2 and 3 , for example, the power tool 10 drives the screwdriver bit 16 to lock a locking element 50 to a predetermined position. When the locking element 50 is in the locked state, the resistance generated by the screwdriver bit 16 and the predetermined position will cause the driving current input to the power tool 10 to generate a surge, and the power tool 10 has The clutch mechanism (not shown) will make the output torque of the output end 18 unable to continue to rotate the screwdriver bit 16 and the locking element 50 .

由於該電動工具10的輸出扭力與電池所提供的電流成正比，若電池提供的電流降低，則該電動工具10的輸出扭力也隨著降低。Since the output torque of the power tool 10 is proportional to the current provided by the battery, if the current provided by the battery decreases, the output torque of the power tool 10 also decreases.

值得注意的是，該感測單元22偵測該電動工具10的電流，並經由該微處理器26傳遞至該顯示器40，當該電動工具10的電流低於一預定數值，則該警示單元30將會警示使用者，進而通知使用者更換該電動工具10的該電池15，藉此避免該電動工具10的輸出扭力不足。It is worth noting that the sensing unit 22 detects the current of the power tool 10 and transmits it to the display 40 via the microprocessor 26 , when the current of the power tool 10 is lower than a predetermined value, the warning unit 30 The user will be alerted and then notified to replace the battery 15 of the power tool 10 , thereby avoiding insufficient output torque of the power tool 10 .
