1.一種手動螺絲松緊工具,單頭、雙頭多規格活動柄棘輪梅花扳手(固定孔的)。是由不同規格尺寸的主梅花套和從梅花套通過鉸接鍵的陰鍵和陽鍵咬合的方式連接的。由于一個梅花套具有兩個規格的梅花形通孔,使它可以用于兩種規格螺絲的松緊,從而擴大了使用范圍,節省了原材料和工時費用。活動扳柄可以方便地調整扳手使用角度。這種扳手用于螺絲的松緊操作,具有適用性強,使用方便和造價低的特點。     

2.扭矩扳手-也叫扭力扳手或力矩扳手,力矩就是力和距離的乘積,在緊固螺絲螺栓螺母等螺紋緊固件時需要控制施加的力矩大小,以保證螺紋緊固且不至于因力矩過大破壞螺紋,所以用扭矩扳手來操作。首先設定好一個需要的扭矩值上限,當施加的扭矩達到設定值時,扳手會發出“卡塔”聲響或者扳手連接處折彎一點角度,這就代表已經緊固不要再加力了。

3.它們的區別在于,扭矩扳手的力矩可以設定。
