三、手動扳手的特點

1、操作簡單

手動扳手的使用相對簡單，操作者只需根據被緊固或拆卸的緊固件的特點，選用相應的扳手。旋緊操(cao)(cao)作時(shi)(shi)(shi)，用手握扳(ban)手柄末端，順時(shi)(shi)(shi)針方向(xiang)(xiang)用力旋緊；旋松操(cao)(cao)作時(shi)(shi)(shi)，逆時(shi)(shi)(shi)針方向(xiang)(xiang)旋轉即可。

2、價格低

相比電動扳手等高級工具，手動扳手的價格較低，更適合于預算有限的場合。其制造成本也相對較低，使得手動扳手在市場上(shang)具有較高的(de)性價比。

3、勞動強度大

手動(dong)扳手需要操作(zuo)者手動(dong)施加力量，因此勞動(dong)強(qiang)度相對較(jiao)大(da)。這也限制了其在一些需要快速、高(gao)效完成工作(zuo)的(de)場合的(de)應(ying)用(yong)。然而，在普通生(sheng)活工作(zuo)、機械檢修(xiu)、設備裝置、家用(yong)裝修(xiu)、汽車修(xiu)理等領域，手動(dong)扳手仍然發揮(hui)著重要作(zuo)用(yong)。
