一、手動扳手是什么

手動扳手又被稱為扳手，是一種常用的機械工具，通常由一把手柄和一組可旋轉的螺口組成。手動扳手一般用于擰緊和松開螺絲和螺母，比較適合小型和中等型的機械作業。手(shou)動(dong)扳手(shou)有許多不同的(de)(de)種類和尺寸，不同的(de)(de)手(shou)動(dong)扳手(shou)適用于(yu)不同的(de)(de)螺(luo)絲(si)和螺(luo)母(mu)，需要選擇合適的(de)(de)扳手(shou)來完成工作。

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(xuan)緊操作(zuo)(zuo)時(shi)，用(yong)(yong)手握扳手柄末端，順時(shi)針(zhen)方向(xiang)用(yong)(yong)力旋(xuan)緊；旋(xuan)松操作(zuo)(zuo)時(shi)，逆時(shi)針(zhen)方向(xiang)旋(xuan)轉即(ji)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(zai)市場(chang)上具有(you)較高(gao)的性(xing)價比。

3、勞動強度大

手(shou)動扳(ban)(ban)手(shou)需要(yao)操作(zuo)(zuo)者手(shou)動施加力量，因此勞(lao)動強度(du)相(xiang)對較大。這(zhe)也限(xian)制了(le)其(qi)在(zai)一些(xie)需要(yao)快速、高效完成工作(zuo)(zuo)的(de)(de)場合的(de)(de)應用(yong)。然而，在(zai)普通生活工作(zuo)(zuo)、機械(xie)檢修、設備裝(zhuang)置、家用(yong)裝(zhuang)修、汽車修理等(deng)領域(yu)，手(shou)動扳(ban)(ban)手(shou)仍然發揮著重要(yao)作(zuo)(zuo)用(yong)。
