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。手動扳手有許多不(bu)(bu)同(tong)的(de)種類和尺寸，不(bu)(bu)同(tong)的(de)手動扳手適(shi)用于不(bu)(bu)同(tong)的(de)螺絲(si)和螺母(mu)，需要選擇(ze)合適(shi)的(de)扳手來完成工作。

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(jin)操作時(shi)(shi)，用手握扳手柄末(mo)端，順時(shi)(shi)針(zhen)方向(xiang)(xiang)用力旋(xuan)緊(jin)；旋(xuan)松(song)操作時(shi)(shi)，逆時(shi)(shi)針(zhen)方向(xiang)(xiang)旋(xuan)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(shi)場上(shang)具(ju)有(you)較高的(de)性價(jia)比。

3、勞動強度大

手(shou)動扳手(shou)需要操作者手(shou)動施加(jia)力量，因此勞動強度(du)相對較大。這也限制了其(qi)在(zai)一些需要快速(su)、高效完成工作的場(chang)合的應用(yong)。然(ran)而，在(zai)普(pu)通生活工作、機械(xie)檢修(xiu)、設(she)備(bei)裝置、家用(yong)裝修(xiu)、汽車修(xiu)理(li)等領域，手(shou)動扳手(shou)仍(reng)然(ran)發揮著重要作用(yong)。
